*** UPDATE: The Fenix series has had two generation updates since this post. Check out the in-depth reviews for both the Fenix 5 Plus, and the Fenix 6! ***
It’s been nearly three months since Garmin first announced the Fenix 5 series, a lineup of three core watch sizes/models (5/5S/5X), that spans 14 variants in total. And that’s before we even talk straps. This line builds upon the Fenix 3HR introduced a year ago, which in turn built upon the Fenix 3 from a year prior to that. Yet it incorporates elements seen in the super-pricey Fenix Chronos that came out last summer (don’t worry, that product line gets all these updates too).
Since introduced, I’ve been testing a pile of watches. I’ve amassed 63 workouts on them in that time frame across three continents and from tropical waters to the icy mountains of the Alps. Not to mention the stack of workouts that The Girl (my stunning wife) has done on the Fenix 5S variant. Neither the dog nor the baby have participated in this round of testing. Slackers.
While much of the earlier testing is on beta software/hardware, recent testing over the last month has been on final hardware and largely final software. Plus, units started shipping last week to consumers around the world. As such, it’s most definitely in-depth review time. Like always, once done with the loaner units I’ll stick them in boxes and send them onwards back to the folks at Garmin and go out and get my own via normal retail channels.
With that – let’s get on with it.
Executive Summary – What’s new:
If you’re already an old hand at knowing what’s new about the Fenix 5 series, then you can honestly skip this section. But, if you’re just arriving here for the first time…then let’s get you all caught up before I dive into actually using it.
So what’s so different about the Fenix 5? Well, the two biggest pieces would be it now has maps on the Fenix 5X edition (legit maps!), and that there are three sizes now. Previously there was just one size with a crapton of different bands. Now there are three sizes with an equally large crapton of bands.
For now, let’s talk about all the differences – both nuanced and big. But first I need to explain that there are three editions of the Fenix 5:
Fenix 5S: 42mm wide, smaller wrist focused – offered in regular glass and Sapphire glass Fenix 5: 47mm wide, baseline – offered in regular glass and Sapphire glass Fenix 5X: 51mm wide, includes mapping – only in Sapphire glass
Each of these three editions is then split into basically two categories: Sapphire and non-sapphire. Except the 5X, which only has Sapphire. What’s most notable though is that the non-Sapphire editions do NOT have WiFi (kinda like Garmin Fenix Chronos). Whereas the Sapphire editions all have WiFi.
With that in mind, I’ll note each of the new features below, and whether they are specific to a given version. If no specific version is noted, then it’s applicable to all versions. In the below, I’m largely using the Fenix 3/Fenix 3HR as my baseline for changes.
Display: 5/5X Went from 218×218 pixels to 240×240 pixels (except 5S, which stays at 218×218). Display: Went from 16 colors on Fenix 3 to 64 colors on Fenix 5 Display: Now supports Emoji, right to left languages (Arabic and Hebrew) Connect IQ: Fully supports CIQ 2.2.3+, as well as 64KB for Widgets, 32KB for Data Fields, and 128KB for apps Battery: Increased battery life up to 24 hours (Fenix 5) in GPS at 1s, or 14hrs for the 5S, and 20hrs for 5X Battery: Increased UltraTrac battery life to 75 hours (Fenix 5, less for 5X) Gyroscope: Added Gyroscope to all models, used to increase track points in UltraTrac mode User Interface: Slight tweaks to UI to match Fenix Chronos series User Interface: Added new quick access controls menu, to access apps/widgets Strava: Added Strava Live Segment support for Bike & Run Sensors: Added Varia Vision Heads Up Display Support (all ANT+ remote displays technically) Sensors: Added Varia Bike Lights (all ANT+ lights technically) Sensors: Added Varia Bike Radar (all ANT+ radar technically) Sensors: Added Shimano Di2 Shifting, ANT+ Gear Shifting Support (SRAM RED eTAP & Campagnolo EPS) Sensors: Added ANT+ Muscle Oxygen Sensors (MOXY/BSX) Sensors: Added Bluetooth Smart sensor support (HR, Power, Speed, Cadence, Footpod) Optical HR Sensor: Revamped tech, now records 24×7 data every 1-2 seconds Optical HR Sensor: Flattened out even more, virtually flush with back of unit Training Data: Added FTP Estimation for cycling Training Data: Added new Training Load functionality Training Data: Added split of aerobic and anaerobic training effect Training Data: Now supports Swimming PR’s (along with previously added Swim Structured Workout support) Live Group Tracking: Added to all Fenix 5 models, à la the Edge 820 group tracking Golf: Added TruSwing, Greenview, and Autoshot features Other Sports Added: Mountain Biking, Treadmill and Indoor Track separated, Ski and Snowboard separated, Navigate app, and Track Me app Navigation Functions: Added Proximity and Navigation Alerts (for distance to waypoint, and time/distance remaining to destination) 5X Only – Mapping: Includes Topo maps in package, can add your own maps if you want 5X Only – Mapping: Ability to display mapping for current position 5X Only – Mapping: Ability to create automated running/riding routes (round trip mapping 5X Only – Mapping: Can find POI’s around you (i.e. food, including Chipotle) 5X Only – Mapping: Routing engine can ingest GPX & FIT files for turn by turn navigation
Got all that?
Ok, but what’s been removed or no longer present compared to the Fenix3 series? Well, according to Garmin it’s purely one thing: WiFi on the base models (Sapphire glass models have it).
Oh, one last thing. Wondering why there’s not a Fenix4? That’s because the phonetic pronunciation of that in Chinese roughly translates to ‘fast rise to quick death’. Not exactly the starting point Garmin wanted to begin with.
If you’re looking for the complete ‘what’s new’ wrap-up in one go, then here’s a detailed video that covers it all:
Ok, let’s get crackin’ on this box.
Editions and Unboxing:
There are 14 versions of the Fenix 5, which fall into the three basic groupings: Fenix 5S, Fenix 5, Fenix 5X. I talk about the basics of those in the previous section. Of course, within that, each model has different things included in the box. For example on some of the higher end Sapphire glass variants, you also get a secondary strap.
Trying to keep track of all the Fenix 5 versions? Join the club. Feel lucky you don’t have to type it all out and ensure it’s correct. Here’s the best way to think about it.
First, choose your watch size:
Fenix 5S – 42mm: This is the smaller one, unofficially targeting women Fenix 5 – 47mm: This is your standard issue one, officially targeting everyone Fenix 5X – 51mm: This is the mapping one, it’s bigger to fit in more battery/storage/processing
Here’s how these three look side by side, assuming you were just using the simple silicon band (no fancy bling) – Fenix 5S, Fenix 5, and then Fenix 5X:
Next though, you need to choose whether or not you want Sapphire glass. That drives whether or not you get WiFi. In theory, it also might prevent your unit from getting scratches on the lens. In reality, that’s usually not the case.
Fenix 5S: Non-Sapphire is $599, Sapphire is $699 Fenix 5: Non-Sapphire is $599, Sapphire is $699 Fenix 5X: This ONLY has Sapphire, starting at $699
Decided what size and version you want? Ok, good. Now you get to decide what bands you want. Here’s how that rolls out:
Fenix 5S – $599: White bezel with white silicone band (band officially called ‘Carrara’) Fenix 5S – $599: Silver bezel with turquoise silicone band Fenix 5S – $599: Silver bezel with black silicone band Fenix 5S Sapphire – $699: Black bezel with black band (+ includes a yellow silicone band) Fenix 5S Sapphire – $699: ‘Champagne’ bezel with gray suede band (+ includes a white silicone band) Fenix 5S Sapphire – $849: ‘Champagne’ bezel with golden color metal band (+ includes a black silicone band) Fenix 5 – $599: Slate gray bezel with black silicone band Fenix 5 – $599: Slate gray bezel with yellow silicone band Fenix 5 – $599: Silver gray bezel with granite blue silicone band Fenix 5 Sapphire – $699: Black bezel with black silicone band (+ includes a yellow silicone band) Fenix 5 Sapphire – $849: Slate gray bezel with metal band (+ includes a black silicone band) Fenix 5X Sapphire – $699: Slate gray bezel with black band Fenix 5X Sapphire – $849: Slate gray bezel with metal band (+ includes a black silicone band)
Oh no no, we’re not done yet. Finally, you need to decide if you want a bundle or not. The bundle is only offered in the following editions, so if you want an HR strap bundle (that comes with the HRM-TRI strap), for capturing swim workout data), then you have to pick one of the two specific bundles offered (neither 5S or 5X). Burger King this is not.
Fenix 5 – $699: Slate gray bezel with black silicone, with HRM-TRI strap Fenix 5 Sapphire – $769: Black bezel with black band + yellow silicone band, with HRM-TRI strap
Got all that? Good. That makes one of us.
Now, you may be wondering about all these bands. Officially they’re called QuickFit bands, as they are designed to pop on and off super-quick. And indeed, they do with a single button press. There’s virtually no risk of these popping off in an open water swim or the like, because the lever is below the band against your wrist.
The idea being you can buy extra bands of differing colors as you see fit. And oh – these QuickFit bands are also compatible with the Garmin Fenix3 series as well. Because I’ve gotten tired of typing out spec sheets, I’m going to go into abbreviated mode now. The bands are as follows:
All of which is a long-winded way of saying: Your mileage may vary on the unboxing front. I’m going to go through the unboxing of a single unit here in photos/text, and then I’ll cover all the three core units in the video below.
First up – we’ve got the box itself. This box happens to be the Fenix 5S Sapphire edition. But again, you can check out the full video of all three units in a moment.
Inside that box you’ll find the watch looking up at you, with all the parts goodness below the surface.
So what’ve we got? Well first up is the watch itself. Here’s the front and back.
Then we’ve got the secondary suede strap in there.
Of course, with the QuickFit system, you can pop it on and off super quick. The Girl has been doing that with this 5S for a while now. For workouts she uses the white silicone strap, and for the rest of the day, the suede strap.
Next, we’ve got the charging cable. It’s new to the Fenix 5 series, but Garmin says it’ll now become the standard for all future wearables. One cable to rule them all.
Lastly, there is the quick start guides you saw above. However, I want to take a brief diversion to talk about that cable. Due to that, I present you this video below I put together – which shows both the upside and downside to the new charging cable.
Finally, as promised, here’s the mother lode of unboxing videos – with all three editions unboxed, plus size and weight comparisons. It’s like knocking out two sections of this review in one sitting:
Ok, let’s move onto the comparison section.
Weights & Sizes:
You asked for it; it’s time to talk size between the units. Here are the exact specs of the three sizes (plus the Fenix3 HR at the bottom for comparison):
Fenix 5S: 1.7” x 1.7” x 0.6” (42.0 x 42.0 x 14.5 mm) – 67g Fenix 5: 1.9” x 1.9” x 0.6” (47.0 x 47.0 x 15.5 mm) – 87g Fenix 5X: 2.0” x 2.0” x 0.7” (51.0 x 51.0 x 17.5 mm) – 98g Fenix 3 HR: 2.0” x 2.0” x 0.6” (51.5 x 51.5 x 16.0 mm) – 86g
But that can be hard to conceptualize, so instead, let’s make it easier in simple text. Note, in the below I’m specifically talking about the width of the watch (round part), not so much the depth.
Fenix 5S: Roughly same size as Forerunner 735XT/230/235 (techically slightly smaller than those) Fenix 5: Slightly larger than the 5S, but smaller than Fenix3HR Fenix 5X: Virtually identical to Fenix 3 HR in size (except not as deep)
Note that technically the screen on the 5S has less pixels (218×218) vs the 5/5X (240×240), but it retains the same color (64 colors). There’s no changes in terms of contrast or display brightness between any of the watches, or compared to the Fenix 3 series. If you liked the Fenix 3 brightness, you’ll be fine with the Fenix 5. And if you didn’t like the Fenix 3 brightness, you probably won’t like the Fenix 5 brightness.
First up, let’s look at just the three core watches side by side:
Next, for fun, let’s add in the Fenix 3 HR as a bit of a benchmark on size. You can see that the Fenix 5X and Fenix 3HR are identical in terms of face size. This is why you can switch the new bands on the Fenix 5X to the Fenix 3/3HR lineup. Whereas the Fenix 5 and Fenix 5S won’t be compatible with the older Fenix 3/3HR bands.
Now let’s get all horizontal and see how they stack up. Here it’s super clear just how big the optical HR sensor bump is on the back of the unit.
What? You’re into optical sensor bumps. If that’s your thing – then here’s two more pictures comparing the Fenix 5 to the Fenix 3HR optical HR sensor bump:
Now let’s throw them all down on the pavement and see how they shake up. I tossed in the Fenix Chronos, FR920XT, and FR735XT in there. Note that the FR735XT shares the same exterior shell dimensions as the FR230 and FR235. So if you’re familiar with those watches, that should help you understand a bit.
And here’s the depth on them. You’ll notice just how much that bump from the Fenix 3HR has been reduced with the new optical sensor design on the Fenix 5 series (or even compared to Chronos). Keep in mind on Chronos it’s thinner in part because of the fact it has less battery. The sensor bump is still bigger on Chronos than the Fenix 5
Next, just two lonely watches to more clearly show just how close the Fenix 5S and FR735XT are in size.
But I hear ya – sensor bumps aren’t your thing. Instead, it’s wrist fetishes. No worries, I’ve got you covered. Here’s my wrist with all the units on it.
Oh no…we’re not done yet! Here’s some additional photos on a small women’s wrist (The Girl) of the three models:
She notes that she likes the size of the 5S the most, though wishes the poles were a little bit smaller.
And then here’s the same three models on my brother’s wrist, which is a bit larger than my wrist (which is the wrist seen for all other photos in this post):
Phew – more than you ever wanted to know probably!
The Basics:
I’m going to mix things up a little bit in this review from past reviews. Partly because I get bored writing things in the same structure each time, and partly because I think at this point there’s some things that are considered ‘base’ knowledge. Meaning that I’ve often split up into separate sections swim/bike/run, with there being so much overlap between all three sections. For this I’m going to round-up the watch basics into this section, then sports into the next, and then talk about unique Fenix 5 pieces like the new Training Load components. Then I’ll separately dive into accuracy.
To start with, you’ve got the watch face. While it may look similar to the Fenix of the past, there’s actually a fair bit of customization allowed under the cover. Virtually every element, including the data fields (even the Fenix logo) can be customized to your liking. And that’s before you even talk going to Connect IQ to download a watch face by a 3rd party, or using a photo with the Garmin watch face app.
For example, you can customize to show metrics like steps, calories, sunrise/sunset times, altitude, text message notifications, miles run, and more.
New to the Fenix 5 is also the ability to quickly access widgets and functions. That’s done by simply holding the upper left button, which opens up a ‘wheel’ of controls These include functions like locking the screen, enabling do-not-disturb mode, or controlling music. You can slightly customize these, by adding other functions like quick-access to the VIRB camera controls, setting time quickly via GPS, or the timer and stopwatch functions. Personally, I’ve found this most handy for just locking the screen (i.e. while skiing to prevent accidental presses from gloves).
Next, it’d be remiss to not mention the activity tracking that occurs. This has been standard on Garmin wearables for some time. It tracks your daily steps and movement, including stairs (using the barometric altimeter. You can either add these stats to the front watch face, or you can simply press the down button to get to the activity tracking page, which shows your steps towards your goal for the day. That goal is constantly shifting – attempting to motivate you to walk more.
All of this activity tracking data is, of course, available through the Garmin Connect Mobile app, on iOS/Android/Windows Phone (as well on online via web browser). The app syncs continuously throughout the day in the background.
A notable change to the Fenix 5 series is the updated optical HR sensor in relation to 24×7 monitoring. While the Fenix 3 HR had an optical sensor, and it also monitored your HR 24×7, it didn’t quite update as frequently as it could have. Sometimes it’d be every few seconds, and yet other times it’d be hours in between updates (during workouts, it was always every second). With the Fenix 5 however, the optical sensor has been reengineered to sample every 1-2 seconds.
That sampling is then uploaded along with your daily activity data to Garmin Connect. While Garmin notes that some people may not see a major improvement in the visual graphs shown on GCM for your daily heart rate, I certainly have. They noted that behind the scenes all that data is captured, but that a lesser set is shown online (logical, since you don’t really want to try and display 3,600 data points per hour, times 24 hours, on your mobile app). In any case, here’s what that looks like.
All of this data can be used to track your all-day heart rate. I’ve talked about this in the past, but the benefit of tracking resting heart rate is to identify trends, such as getting sick. In fact, it was easy to see over the last few weeks when my resting HR went from being in the low 40’s, up to upper 50’s – that I was getting sick (and sure enough, I was).
As you may have noticed above, you’ll also get automatic exercise recognition for certain sports like running, walking and cycling. Note that this doesn’t turn on the GPS, but rather is just using accelerometer data. You can tap these to get further details about the activity. For example, above you can see those little grey circles. One is when I walked to dinner, and another when I walked home from dinner. Below you can see the level of detail I get about each one (one going to dinner, one going from dinner), which is simply just the distance and start times (5:50PM vs 8:50PM).
I’d strongly recommend though that any time you do an actual legit workout, just use the normal sport modes. That’s going to give you the data recording you want. Otherwise, the automatic exercise recognition is basically just for capturing random walks around town, a quick commuter ride around town, etc…
Next, we’ve got smartphone notifications. For the most part, these are pretty similar to the past. The Fenix 5 supports the standard notification centers on your smartphone, so any app can trigger notifications. From Twitter to texts, and Snapchat to Strava. These will simply appear on your wrist and you can view them as-is, or press to get further details. Alternatively, you can clear them. Anything cleared will also clear on your smartphone. Further, you can open up the widget to view any missed notifications.
Note that what is new in the Fenix 5 is the support for Emoji icons, enabling you to finally see your smiley icon in its full black and white text glory.
One last basics item to cover is WiFi. The Fenix 5 has WiFi included *only* on the Sapphire edition units, so basically, the more expensive ones. WiFi is utilized to allow for quicker uploading of workouts, as well as sync of data like updates. Realistically it’s not all that much faster than Bluetooth Smart. But it is kinda convenient to just walk in the house and have things upload the second you close the door from a run.
To configure WiFi networks, you can use Garmin Express, which allows you to list numerous networks. Note that you can’t connect to proxy/filtered networks (like a Starbucks or most airport networks). But home networks, MiFi access points, and such are all good.
With that – we’ve covered all the non-sporting basics, aside from a run through the settings control panel. But if you’d like to see what’s in store there, then simply hit up the below video – where I walk through the entire watch user interface, screen by screen!
It’s time to move onto getting active with it, and seeing how it works in sport use.
Sport Usage:
Now to dive into what we’re all here for: Using the darn thing for sport. After all, while the Fenix 5 is a great day to day smartwatch, the reason you buy it is likely for outdoor sports goodness. Or at least, some sports goodness.
I’m going to iterate through some basics on a few core sports, but keep in mind that for the most part everything from a core functionality standpoint in one sport applies to another sport. Meaning aspects like data field customization, alerts, etc… are all basically the same. Where things differ of course is connectivity to sensors (e.g. power only in cycling, at least without Connect IQ add-ins), and then also how certain metrics are displayed. For example, you’d get pace in running versus speed. But many metrics can be tweaked – such as whether you want to see altitude in meters or feet. I actually like to mix and match that myself, where I’ll keep pace/speed in MPH, but altitude in meters while riding in Europe.
So, let’s talk running first. To start up any sport we’ll hit the upper right button. That brings us to the sport selection screen. It’s here we can choose any of the default sports, customize some (like triathlon mode), and add others. Also, we can access standalone apps – such as 3rd party apps or even 1st party Garmin apps like the HRV Stress app or Navigate app.
In any case, we’ll choose running – and in this case, an outdoor run. For an indoor run, you’d select ‘Treadmill’.
Once that’s selected it’ll go off and find satellites. You can see the status of this by the ring around the edge of the watch. Wait until it’s green. Red is bad, and orange is less bad. Green is good. In general, I like to wait a few seconds extra (10-15 seconds) before starting, after it’s green. This ensures it’s truly got good legit satellite coverage. A few folks have also noticed that on the very first GPS activity you do outdoors (ever), you may want to give it an extra minute or so before starting. That seems to help significantly.
At the same time, it’s going to be acquiring your heart rate optically. You can see this by the little HR icon at the top. When it’s blinking, it’s thinking. When it’s done thinking, it stops blinking and stays lit. Don’t run till you’ve got it lit full-on.
If you’re using a heart rate strap (external), or a footpod, it’ll go off and connect those accessories. Of course, ensure you’ve got them paired first.
Next, let’s talk data fields and data screens. This basically applies to all sports. Essentially, you can customize the crap out of data fields and screens. No device on the market gives as much customization as this. You’ve got customizable data pages (screens), that can have up to 4 fields each. That can be one field, two fields, three fields, or four fields. And then within both three and four fields you can arrange them two different ways each (technically three ways for three fields – one without field titles).
You can create numerous custom data pages, I haven’t figured out the limit because you can create so many. But you can also select from standard data pages that can be lightly customized as well. These include: Virtual Partner, Map, Compass, Elevation (Graph), Music Controls, Running Dynamics (x2 pages), plus a heart rate zone page. Lots of pages.
I tend to keep mine somewhat basic. Essentially I’ve got a page focused on workout totals (i.e. total distance, total time, etc…), and then another focused on laps (i.e. lap distance, lap pace, lap time, heart rate). Btw, you can select either automatic laps based on a preset distance or manual laps based on pressing the button.
Within laps, you can also customize a lap banner, which will display the lap details after pressing the lap button. So you can mix and match what data you want there. I’d point out that this is the one area that Suunto has an advantage over Garmin, with their Spartan series. They’ve got a super cool lap summary page. Ironically, this lap summary page is modeled in turn after what Garmin did on their Edge series devices. But alas, it’s never come to the wearables lineup.
Note Suunto also can now do 7 data fields per page, though I honestly haven’t had much of a reason to need more than four on a wearable. So one could argue that’s a benefit for Suunto, though again, I think the real strength is their lap page.
In any event – let’s actually just run. Once running (after you’ve pressed start), it’ll record all your data including your location. In order to show how instant pacing works and responds, I’ve put together this quick video:
While running you can, of course, change data pages at any time by pressing the up/down buttons. Heck, you can even customize the data fields mid-workout if you so choose (something you can’t do on Suunto/Polar devices). It’s all pretty darn flexible.
Once done with the run you’ll get summary and PR information – such as longest run, or fastest 5K run, etc… You’ll also get recovery time metrics (more on that in the next section), and workout benefit details.
And then finally, you’ll find your workout will sync via Bluetooth Smart or WiFi (if your unit has it), or you can just plug it in. It’s here you can then explore the activity online using your mobile app or browser. Also, if you’ve connected to Strava, TrainingPeaks, or one of the other Garmin Auto Sync services, it’ll end up there within a few seconds too.
One final note is that the Fenix 5 still doesn’t support running power meters natively (Suunto does). However, you can use the Stryd Connect IQ data field to get that data. That field will then show up just like a normal power meter field within your data pages, and allow you to record the data online to not just Garmin Connect, but also apps like TrainingPeaks – which will show it as well (seen towards the bottom, with the little ‘IQ’ pieces next to each graph).
Next, let’s talk cycling. Virtually everything I’ve talked about above applies here in terms of data field customization and such. About the only major difference is when we start talking about power meters, which the cycling mode supports.
I talk about sensors in a full section down below, but it’s worthwhile noting here that the unit does now also support Bluetooth Smart power meters and Bluetooth Smart Speed/Cadence sensors (in addition of course to ANT+ sensors it’s always supported).
While riding, you’ll be able to display data from the power meter, as well as any other sensors you have. Plus distance and speed data from GPS, and altitude data from the barometric altimeter. One downside to the Fenix 5 though for triathletes is the lack of a quick release kit. As such, you’ve either got to wear it on your wrist, or pick up one of those cheap $11 rubber mounting blocks for your bike. But those blocks don’t tend to fit triathlon bike bars very well. Hopefully, we’ll see Garmin offer a quick release kit. Given the triathlon season is just getting underway…now would be a really good time for that.
Note that the Fenix 5 supports Strava Live Segments, via the app built into it. This allows you to see your status of a segment you’ve starred, which will automatically trigger when you cross the segment. This is true of both cycling and running. I talk a bit more on how this works in this slightly older post, when the functionality first came out.
Next, let’s move onto swimming. That’s where things get a bit more unique sport-wise. The Fenix 5 supports both openwater and pool swims. For openwater swims, it’ll use GPS. Whereas for pool swims, it’ll use the accelerometer.
I’ve actually got a crapton of experience with openwater swims and the Fenix 5, thanks in large part to being in warmer climates for January-March.
To demonstrate how it all works, I’ve put together this video that walks through step by step both the unit in action, as well as accuracy after the fact:
The key thing to understand with openwater swimming modes on any GPS watch is that it’s a constant struggle for units to figure out where you are. Each time your hand goes under the water, it loses GPS signal. And each time it gets above the water (for all of 1-1.5 seconds), it partially regains it. Usually, it doesn’t regain enough signal to know exactly where you are – so instead it starts trying to plot based on a spread of points. That’s why openwater swims are rarely perfect in track length. As a general goal, I find anything within +/- 10% to be acceptable for openwater swim distance. Obviously, I’d prefer it be spot on, but plenty of openwater swimming over the years says that’s roughly the line in the sand.
There are things you can do to improve your success rate though:
A) Always get signal above water before starting
B) Always press the start button above water, and then wait for 2-5 seconds before your first strokes
C) If making a sharp turn somewhere (such as a buoy), I find it helpful if you slightly slow down your stroke rate at the turn buoy – giving the unit just an extra split second of your wrist above water to try and find GPS
D) Always wait until out of the water to stop the GPS track, ideally waiting 5-8 seconds for it to ensure it has a clean lock on GPS
If you do those four things, I find substantial improvements in GPS tracking during swims (across all device vendors). None really impact your workout.
Next, let’s talk pool swims.
As noted earlier, for this it leverages the accelerometer in the unit. That’s then combined with a known pool length, which it’ll prompt you to select it from some common lengths. You can also customize the length as well if you’re pool is wonky. Once it’s set, it’ll remember it for future swims – but you can easily change it if you pool-hop.
Overall I found no issues with the swimming on the Fenix 5 throughout a few different pool swims in both an empty pool and a busy pool (18 people in my lane).
As always though with (all) pool swimming and accelerometers, there’s a few tricks you can use as well to get better accuracy:
A) Obviously, ensure your pool length is right
B) The key to swimming watches is remembering it’s looking for a ‘cue’ as to when you’ve reached the end of the length. So, push off forcefully each time
C) It doesn’t matter if you do flip turns or open (non-flip) turns, I mix and match depending on the craziness at the end of my line
D) Again, just push off sharply, no matter what you do
E) Avoid stopping/starting mid-lane, since it’ll confuse things
F) If you have to pass someone mid-lane, it’s best to ramp into that pass as evenly as possible. Versus just instantly sprinting mid-lane, since it may think you’ve just done a new length. I realize that’s easier said than done – but just giving some general advice
G) Don’t do the YMCA song at the end of the lane, even if at the YMCA. Also, if you go the bathroom, pause the watch.
Speaking of pausing, note that the Fenix 5 does include an inverted display color when you pause it – so you can know whether your mid-set or not. Also, you can use drill mode for things that don’t involve your wrists (i.e. kickboard drills). That allows you to simply enter in the total distance for that drill set at the end of the set.
Once you’re done, you’ll get summary data on the watch, but you’ll also get it of course on Garmin Connect as well. Both per length data as well as per-set data.
Ok – with all three core triathlon sports taken care of, let’s briefly talk about triathlon mode. This is the key element to a multisport watch, and enables you to seamlessly transition from sport to sport, all within a single recording. It’s what differentiates a Garmin/Polar/Suunto multisport watch from a TomTom watch that may support all three sports individually, but not as a single workout/race.
With the Fenix 5 you’ve got a triathlon mode that by default includes openwater swim, outdoor cycling and an outdoor run. It’ll also capture transition times too. You just press the lap button to change to a new sport.
One tip I’d recommend is during a triathlon, is to lock the watch. Garmin actually offers an automatic locking option after each sport (you can enable/disable it per sport), so that it’ll automatically lock as soon as you change sports. To change sports again, you’ll hold to unlock, then press again to change.
Next, if you want to customize the multisport mode you can do so too. For example, to do an indoor triathlon, or to do a duathlon. Or to do a brick workout. Also, you can just make-up a multisport mode on the fly by simply holding down the middle left button and changing the sport to something else. Basically it offers never-ending multisport mode.
Speaking of making things up – you’ve got the ability to select numerous other sports, as well as customize those sports. Here’s the grand total of sports that I see on the watch today:
Running: Run, Trail Run, Treadmill Run, Indoor Track Hiking: Hike, Climb, Walk, Navigate Cycling: Bike, Bike Indoor, Mountain bike Swimming: Openwater Swim, Pool Swim Triathlon: Triathlon Mode, Swimrun, +general multisport mode Skiing: Ski, Snowboard, XC Ski Other water: Stand Up Paddleboard, Row, Row Indoor Other: Golf, Golf TruSwing, Strength, Cardio, Jumpmaster, Tactical, Other (make your own up)
Phew!
Next, let’s talk structured workouts and intervals. Structured workouts are ones that you download from Garmin Connect. You can create them online there yourself, or download ones as part of a plan from them (such as running or triathlon plans).
These can’t be created on the mobile app, but can be sync’d via that app. So you’ll need to edit/create the ones above using a desktop/laptop computer (don’t even bother trying on the app). Once that’s done, it’ll show up on your watch for you to execute:
Typically structured workouts are more complex than basic interval workouts (which I’ll cover in a second). So with a structured workout you may have numerous targets and/or rather complex phases or steps within them. The watch will guide you through each of those steps/targets, and you’re basically along for the ride (or run).
Whereas with interval mode, you’re running through a relatively basic interval workout (basic in structure – it may still be quite painful in terms of execution). With these you’ll go into the interval mode on the unit itself, and then you can customize the interval’s work duration (time or distance or open), the rest period (time/distance/open), as well as the number of reps and the warm-up/cool-down periods.
Once that’s all customized, it’ll iterate through these steps and again, you’re along for the ride. The key difference between this and the structured workout above really gets to the complexity of what you can do. With the interval timer on the unit itself you can’t set targets (i.e. a target pace), whereas with a structured workout you can.
Ok – we’ve covered all of the core sport pieces. Note that the next section will dive into the training and stress pieces, whereas the section after that I’ll talk about navigation and courses. Courses can also be used for pacing as well (i.e. racing against a previous effort), so those do have some overlap there into the sport realm.
Training Load & Stress:
Perhaps the biggest change in the Fenix 5 is the inclusion of new Training Load and Stress metrics, as well as now listing the aerobic and anaerobic training effect (versus just a single training effect before).
At first glance, you’d probably say these were just more puff numbers. But behind the scenes there’s actually a fair bit going on, and it’s including a pretty massive codebase from partner FirstBeat into the watch. All of these metrics are identical to what FirstBeat has been using for years in their pro athlete offering, which is a big software suite that pro teams use to try and gauge training and recovery. Garmin has in turn licensed portions of that, which are now seen in the Fenix 5.
One really important thing to point out is that these metrics take time to adapt to you. Realistically FirstBeat says it takes about two weeks in total to get to the point of having truly valid data. That also assumes that you’re able to get two workouts that trigger a VO2Max estimate (either running or cycling, but two of the same sport type). It’s those two key items that allow it to really hone in. It’ll reach it’s ‘full potential’ once it has about a month’s worth of data on you.
So what type of data is it giving? Well, there’s a bunch of metrics. Nothing here requires a heart rate strap. First, we’ve got the basics – like VO2Max for both cycling and running. These have been around for a while.
Then we’ve got recovery hours. This is a continual timeline of your recovery hours. This grows with each workout, and shrinks over time, like flipping over an hourglass timer. Along the bottom it’ll give guidance on how to train:
Then we’ve got the new Training Load piece. This tells you how much load you’ve had in the last 7 days, and whether that’s optimal, overtraining, or undertraining. Remember though – this is based on understanding you as an individual (which gets to those first few weeks). So it’s looking at your past training load and figuring out what you’re capable of. Said differently: It’ll be different for everyone based on their historical loads.
The specific number given in the middle ranges differently for each person. The below graph kinda helps to put it in perspective. But again – the optimal range will vary by individual.
A couple of things to keep in mind about the Training Load function:
– The number is a 7-day rolling value
– It’ll take one week before you see the first number
– It takes four weeks to be ‘fully calibrated’, inclusive of VO2Max estimates
– It requires either the optical HR sensor be enabled or a heart rate strap be paired to accumulate load
Then we’ve got the previous Race Predictor function. This is pretty straightforward and just does a lookup table based on your current running VO2Max, your gender, and your age. Nothing more, nothing less. This also assumes you’ve done the training such that your legs can maintain that distance. In general, for most people, it tends to be in the right ballpark of their *potential*. Again, you’d have to have the training in the legs to hit that.
Lastly, we’ve got the Training Status screen. This is new, and it’s pretty cool. Up top it’ll tell you your current training Status, followed by whether your fitness level is falling, and if the load is increasing. Here’s mine as of today:
So what’s it telling me? Well, it says that I’m doing unproductive training. That makes sense. I’ve been traveling the last few days, along with skiing. That’s moderately unproductive. Officially, here’s what the description from FirstBeat means:
“Your training load is at a good level, but your fitness is decreasing. Your body may be struggling to recover, so be sure to pay attention to your overall health including stress, nutrition and rest.”
Which is ironically exactly true. I was sick last week, and combined with the travel and weird hours – it’s not ideal. Kinda neat when something works.
In the photo above you’ll see the fitness and load directional arrows. One is showing my fitness is decreasing as a result, while my load is actually slightly up. That’s because I’ve been doing ad hoc (but unstructured) shorter runs the last few days (3-4 days in a row), coming off of skiing for a week. So it’s less than ideal from a training standpoint.
Here’s another example from a few weeks ago, which is showing the opposite, as I was peaking at that point coming off of a strong week.
Next, at the end of every workout, you’ll be given a split of anaerobic an aerobic training impact, in terms of a number between 0.0 and 5.0. While Training Effect used to be a single number, now it’s split.
So what’s the above telling me? Well, there are tons of different phrases it can give back to you:
In order to make that easier, they’ve put them into a spreadsheet, which I’ve uploaded to below. Actually, two spreadsheets:
Finally, note that all of this is displayed on Garmin Connect at the end of each activity, you can see it here:
What isn’t (yet) displayed though is graphs showing this all over time. That would allow you to plot this and determine where you stand with training load in general, and potentially going into an event.
Two last notes – the Fenix 5 includes both the ability to establish Lactate Threshold levels as well as cycling VO2Max. The lactate threshold feature was introduced in the past with the Garmin FR630 and Fenix 3. As was cycling VO2Max on other units. With the lactate threshold feature you do need a heart rate strap (as you do if you want to use the ‘Stress Test’ score app). Also, with the cycling VO2Max test/values, you’ll need a power meter connected. Just wanted to make that clear.
Also, the Fenix 5 can record HRV data from an HR strap to the activity files, if you have specific apps that want to take advantage of that. To enable that you’ll dive into the settings menu and turn that to enabled.
Overall I’ve been pretty impressed with new FirstBeat driven features– more so than I’ve been in the past with similar training status/recovery type metrics. At the end of almost every workout I’d say that the ‘Training Status’ page (i.e. productive, unproductive, etc…), and fitness/load arrows are inline with how I feel. Of course, they’ve got years of experience with his algorithm in their dedicated software platform. Obviously though, I’m interested in seeing how it works for others as well – once folks are able to get 3-4 weeks of time on their units with good data to starting getting details on.
Navigation and Courses (and 5X Maps):
Historically one of the biggest differentiators between the Fenix series and the Garmin Forerunner series has been the navigation capabilities. Turning back the way-back machine to the original Fenix (aka Fenix 1), that was all about navigation. Then over the course of the Fenix 2 and Fenix 3 it became more focused on sports, albeit not to the detriment of hiking/navigation.
What I want to do here is show you how it works to create a course/route, load it onto a unit, and then navigate on it. That’s the basics. But then I’ll show you the unique differences within the 5X, since that has maps on it. Whereas with the 5/5S, they don’t have maps and instead use a breadcrumb style trail with general directional guidance (i.e. compass style).
To begin, you’ll need to create a course. The easiest way is to do this with Garmin Connect, where you can drag and drop your route over a map.
Once you’ve got the route done (I’ve got some tips a bit later in this section), you’ll send it to your Fenix 5. You can do this from the desktop or mobile app. From there it’ll show up in your list of courses on the unit:
Ok, with that all set we’ll crack open the course to navigate on it. It’ll offer the ability to show a map (which is just an outline) as well as the elevation profile. Below is how it looks on the Fenix 5 (non-X), we’ll get to the 5X in just a second.
Within the ‘map’ view (on all Fenix models), you can use the upper right button to iterate between three different zoom/pan functions. See those three tiny circles in the upper right corner? If I press that upper right button it then changes the lower-left button functions. Once for zoom options, once for pan left/right, and once for pan up/down.
While navigating the course it’ll show your current position and then it’ll show your planned route. It’ll also notify you anytime you need to change direction. Further, the little red arrow uses the magnetic compass to point you in the right direction.
If you want you can also select a past activity to follow. In doing so, it’ll actually set it up as a bit of a race, allowing you to pace/race against it while running/riding that course:
And you’ll get your current position within the elevation profile as well.
If you wander off-course, it’ll let you know about that as well (see the little turn indicator counting down along the bottom of the screen below).
And this is to some degree where we get into the key differences between the Fenix 5/5S and the Fenix 5X. When you’re routing on the 5/5S it has no context of what you’re on. It just knows you need to go in a given compass direction. Whereas on the 5X, it actually has routable maps – so it knows you’re on a road/trail.
You can see that below too – it’s not telling me of any impending turns, despite the route being on a twisting road – because it knows I can’t go anywhere but that road.
This is important because when I was on a winding mountain road, the Fenix 5 would constantly notify me at every switchback in the road, even though there was nothing else to do but follow the road. Whereas on the 5X, it knew that I was on a simple switchback, and didn’t notify me to keep following the only road there was (logical).
Speaking of routing, let’s talk a few more 5X specifics. On *only* the Fenix 5X is the ability to do round-trip routing.
This allows you to request a route (i.e. cycling/running) of a given length and if you want a given direction, and it’ll go and find you a course using the map set it has.
Well technically, it will offer up three routes for you to choose from:
You can then execute these courses just like you would any other course. It’s great for running or riding in places you don’t know, since it’s going to leverage cycling routes and other non-car friendly options when available.
I’d note that the creation of the route can take a wee bit of time. Within the city, it would take about 60-90 seconds (easily) per route. Whereas out in the middle of nowhere it was far quicker.
The other downside is that it does depend on the trail data within the mapset. For example in Spain when I was in a hiking mecca, the base mapset (it was a European Fenix 5X edition), didn’t include any (or at least, many) of these local trails. So the only options it gave me for hiking/running were on the main roads. Which was definitely a bummer.
Inversely, in Chamonix in France – I got tons of great options for routing, and many/most trails were understood.
Next, we’ve got the 5X’s ability to search through local points of interest. This means you can lookup a place to eat, or a place to get gas (useful for also finding food or water on a long ride), and many other places:
Once you select a POI, you can route to it as well just like before. This is essentially the same functionality you’d find on the Garmin handheld series. And again, none of this requires a phone to work. It can be done totally without any connectivity. What’s cool about this is the Around Me function, which has the watch tell you everything around you:
Or, you can filter it to just certain categories – like food.
What’s interesting is you if you look above you’ll see a little wedge on the upper right portion of the circle – kinda like two clock hands. This allows you to press the red button and then get a listing of places within just that wedge. Thus narrowing down the list.
You can rotate that little pizza pie around, to zoom in on another section:
And all of this does work pretty darn well. However, there are some tricks to making things work better, especially on route creation.
First, when using Garmin Connect’s site, you’ll likely try first in satellite mode. That’s fine, as that’s the best bet for figuring out routes. However, it won’t always work. For example, in this simple case I tried to create a route between the road and that beach you see down south of it. The red line is what happened when I told it to connect those two points:
So basically, it didn’t find anything there routing wise. Pretty much useless.
Instead, if you try clicking the dropdown in the upper right and select “OpenStreetMap” from the upper left corner, and try again. Ahh….much better!
Note in both cases I left on the option for ‘Stay on Roads’, which also translates to ‘Stay on trails’. Else it’d just connect the two dots and ignore roads.
The point being here that you’ll definitely need to experiment a bit. Also, somewhat frustrating you still have to do this all via desktop computer. There’s no option for doing this via your phone.
And the above is a perfect example of that. On this roadway it’d be very common for folks to stop at that parking lot and then want go to for a few mile/kilometer hike. There are many options (some of them you can plainly see in the map). Yet planning those would require getting back out a desktop computer, unless the Fenix 5X happened to know about it (and in the case of this area, it didn’t know about many trails I tried).
Which ultimately gets to my final point here: The 5X is very cool, and generally quite responsive. And if you’ve done enough planning it works out really well. Or, if you’re just in an area where the mapping quality is good. But if you’re not, then you’ve paid an extra pile of money for something that a $1 phone app tends to do a lot better. Or, as I said years ago in my previous Fenix reviews: I want to be able to plan routes from my phone and then immediately transfer them to my watch. Is that asking too much?
Heart Rate Sensor Accuracy:
The Fenix 5 series includes Garmin’s Elevate optical HR sensor built into the bottom of it, which I used both in workouts as well as in 24×7 continual HR monitoring mode. With the Fenix 5, this sensor got a slight overhaul/upgrade, most notably when in 24×7 mode. Previous to this, Garmin’s Elevate sensor would sample rather infrequently (outside of workouts), at rates from every few seconds to every few hours. It was all over the map.
But with the new lower-power Fenix 5 optical sensor, it now samples every 1-2 seconds. Basically, it’s always on. In addition to the change in sampling frequency, they’ve also reduced the sensor bump. Of course – my goal is to find out if there were any undesired repercussions from this, specifically in sport mode. When it came to 24×7 mode, the new data looks much better, and the accuracy seems spot on for casual activities like watching TV, walking, or just living life.
Thus with each subsequent new unit released I re-visit sensor accuracy. While it’s the same physical hardware, one can see the impact that firmware updates make. Additionally, each watch has a slightly different form factor (exterior design), which can impact accuracy in terms of external light getting into the sensor area (which degrades accuracy of optical HR sensors).
Before we move on to the test results, note that optical HR sensor accuracy is rather varied from individual to individual. Aspects such as skin color, hair density, and position can impact accuracy. Position and how the band is worn are *the most important* pieces. A unit with an optical HR sensor should be snug. It doesn’t need to leave marks, but you shouldn’t be able to slide a finger under the band (at least during workouts). You can wear it a tiny bit looser the rest of the day.
Ok, so in my testing, I simply use the watch throughout my normal workouts. Those workouts include a wide variety of intensities and conditions, making them great for accuracy testing. I’ve got long/steady runs, hard interval workouts on both bike and running, as well as tempo runs and rides. Not to mention skiing and hiking. Night and day, sun and snow. I’ve got it all!
For each test, I’m wearing additional devices, usually 3-4, which capture data from other sensors. Typically I’d wear a chest strap (usually the HRM-TRI), as well as often another optical HR sensor made by Scosche and in some cases also a Suunto Spartan Wrist HR that I’m also testing. I generally consider the Scosche sensors to be the most accurate optical HR sensors for fitness/workouts today. Note that the numbers you see in the upper right corner are *not* the averages, but rather just the exact point my mouse is sitting over.
Let’s dive into the first data set. Note all this data is analyzed using the DCR Analyzer, details here.
First let’s start off with an interval run of sorts. The first part is a bit of a warm-up, and then I go into four interval sets of about 5 minutes each, followed by three slightly more intense (but shorter intervals). On one arm I had the Fenix 5 with the optical HR sensor. On the other I had a Suunto Spartan Ultra paired to a Scosche Rhythm+, and then I had a Fenix 3 paired to an HRM-TRI heart rate strap. Here’s the overview:
So, a couple of things. First up is at the front we see the two optical sensors match nicely, while the HRM-TRI chest strap is a bit low. This is actually an interesting case because the chest strap is wrong here. A classic case of a cooler day (with some light winds) and it taking a few minutes to ‘click’. I believe I added some more spit to the chest strap around the 6-8 minute marker, and adjusted it a bit and then it matched nicely.
And in fact, from that point forward throughout the rest of the intervals things are really very clean and actually some of the best tracking I’ve seen. If I were to nitpick a bit more, it looks like at the end of the first interval the HR strap properly reduces the HR quicker than the optical sensors by a few seconds, but nothing major. You’ll notice at the start of the 3rd interval I appear to ‘lose’ the connectivity to the Scosche. Said another way: The battery died and quite literally flat-lined.
But for the rest of the run, even during the very short/hard sprints at the end, the Fenix 5 is looking quite good.
Next, let’s look at another run (this time back home in Paris). This time a somewhat steady-state run, but it included some rollers, which means my HR was constantly shifting. Additionally, cadence was shifting a bit too as I’d go up/down slight inclines.
At a high glance, things track relatively close. But there are some quirks. For example, early on there’s a bit of separation, which I’ll give the HRM-TRI strap as being the more correct of the two.
And then into the run, if you pick it apart more closely you see where the optical HR sensor seems to be slightly overshooting and occasionally undershooting little shifts in intensity. It’s not massive, and only lasts a few seconds each time. But it is notable.
Most people would consider the above nitpicking, but it’s certainly worthwhile pointing out.
In general, most of my runs mirror the above results. Usually it’s pretty good, and usually it doesn’t miss any major moments. I have found in general if there’s going to be an issue, it’s almost always going to happen in the first 120-180 seconds. While I often wait a few seconds longer after ensuring an HR lock, I haven’t seen that have a major impact on my first few minute success one way or the other.
Next, let’s shift to a cycling. This is historically where Garmin’s optical HR sensors have struggled. I’m going to pick an outdoor ride, namely because you can check out one of my trainer rides below and see it performed almost flawlessly (the optical HR sensor). Outdoor is hard, indoor is easy. This ride was almost 8 hours long, so there’s lots of variability in pacing and such. So I’m really going to focus on one of the climbs I did, since that was a bit more intense.
Here’s that climb, once zoomed in:
You can see it definitely missed the first 4-5 minutes, being offset by about 20bpm (that’s a lot), but then it seemed to lock in pretty well for much of the rest of the climb, save a few moments here and there. Still, not quite ideal.
Next, another section of that ride before a break where a small group of us were rotating through at pretty high intensity for about 10 minutes or so. You’ll notice that it got the general plot correct, but was still off 3-6bpm for fair chunks of time.
And this is in general what I’d see. The Fenix 5 Elevate optical HR sensor is definitely improved over the first generation Garmin Elevate sensors (either via firmware or hardware) when it comes to cycling, but it still leaves a bit to be desired in this area. Personally, I’ll use a HR strap or other optical HR sensor (i.e. the Scosche) while cycling outdoors. For indoor trainer use, the Fenix 5 optical HR sensor seems just fine though (no vibrations on the road to screw it up).
So overall – I’d say things are pretty good (the best we’ve seen from Garmin’s sensor tech) while running, but a mixed bag while cycling. Note that Garmin doesn’t enable the optical HR sensor during swimming (either indoor or openwater), except to simply sample for your 24×7 HR. So while you’ll see the light go on and off, that data isn’t recorded to the workout file. Garmin has experimented more with this in recent months, but still doesn’t believe the accuracy is there yet to keep it on while doing swim activities. For that, you’ll still need/want either the HRM-TRI or HRM-SWIM straps to pair with.
Lastly, here’s a table of all my activities on final or near-final software from the last couple of weeks:
Garmin Fenix 5 Data Sets

GPS Accuracy:
There’s likely no topic that stirs as much discussion and passion as GPS accuracy. A watch could fall apart and give you dire electrical shocks while doing so, but if it shows you on the wrong side of the road? Oh hell no, bring on the fury of the internet!
GPS accuracy can be looked at in a number of different ways, but I prefer to look at it using a number of devices in real-world scenarios across a vast number of activities. I use 2-6 other devices at once, trying to get a clear picture of how a given set of devices handles conditions on a certain day. Conditions include everything from tree/building cover to weather.
Over the years I’ve continued to tweak my GPS testing methodology. For example, I try to not place two units next to each other on my wrists, as that can impact signal. If I do so, I’ll put a thin fabric spacer of about 1”/3cm between them. But often I’ll simply carry other units by the straps, or attach them to my shoulder straps of a CamelBak. Plus, wearing multiple watches on the same wrist is well known to impact optical HR accuracy too.
Next, as noted, I use just my daily training routes. Using a single route over and over again isn’t really indicative of real-world conditions, it’s just indicative of one trail. So my training over the last nearly 3 months have covered over 61 workouts with the Fenix 5 in the following locales:
Cycling: Australia, France, Spain, United States Running/Hiking: Australia, France, Spain, Finland, United States Openwater Swimming: Australia, Spain Skiing: France, Italy
These have included the following condition types:
Dense forests, desert mountains, cliff-laden mountains, the highest peaks in the Alps, tons of city running/cycling, light forests/suburbia, generic dessert (flats), coastal roads, open oceans
Almost all of my activities are available on Strava from the last three months, and almost all of those are from the Fenix 5.
When it comes to the data I’m focusing on for accuracy details in this review, I’m going to mostly limit it to the last few weeks, since earlier data was beta data. Though even in earlier beta conditions, I rarely had issues with GPS accuracy. During the beta (where software is being worked on), the only issues I saw were related to openwater swimming – but Garmin has since addressed those. I also saw a weird quirk with respect to tunnels, which Garmin has also since addressed (or at least, I haven’t seen it again). Such as in my run yesterday it are tracked through this tunnel area.
So while I’m focusing on data from the near-term, since that’s largely on final/production firmware – this data is indicative of the kind of data I saw throughout my time period with the unit.
First, let’s just start off with a run. Note all this data is analyzed using the DCR Analyzer, a tool you can use as well. Details here.
This run is fairly straight-forward in that it’s along the beach in Barcelona, but I figure it’s a good place to start. Plus, I make some nice turns/loops near some buildings to add a layer of complexity.
While running along the main portion of the boardwalk, things were just fine – which is largely to be expected. It’s pretty open.
Once I got towards the end of this stretch of beach, I decided to do some interval loops around a set of buildings. These buildings, in particular along the roadway, would have me running within 1 meter of 6-8 story structures. A great place to see how well it could hold a track.
Looking at the above, the Fenix 5 most accurately tracked where I was. The Fenix 3 in second place, and the Spartan Ultra cutting the corners at every opportunity. The Fenix 5 even correctly tracked when I brain-farted and missed the turn at the very southern tip – having to turn back around slightly.
Let’s look closer though at going down the roadway next to the buildings (left side):
You can see here that the Fenix 5 easily threads the needle on this, keeping my track properly between the two sets of buildings. Good stuff. Interestingly however, each time I passed this massive lookout tower, all three units veered left (even though I stayed to the right). Clearly some sort of interference going on there.
I run this route a lot as a test route. And in particular I’m looking for a few things. First, does it correctly cross the bridge and not cut the corner. In this case, the answer is yes, it nails it.
Next, as I go down the tree and building lined canal – does it follow my track and not get distracted by large structures?
On the way in (right side), the answer is yes, it stays on the track quite nicely. On the way out (left side), it almost perfectly gets it, but then takes one diversion into the side of the building by about 5m, just as I crossed the road up against the building.
Next, how does it handle the tunnel, highlighted in yellow (about 200m long)? I’m looking here for it to not get distracted and go off into the buildings at either entrance/exit when it loses satellite reception. It does so better than the FR735XT, though not quite as nicely as the Suunto Spartan Ultra (though, up above the Spartan Ultra is in the buildings for most of the canal test area).
Finally, as I come back onto the islands, I’m looking that it manages to hold track without putting me in either the water or the buildings. This is another really tough spot because of the tight roads and tallish buildings. But it does well, without any issues.
Note, I would move onto a cycling activity – but I’ll be honest – they’re boring. And they all look perfect. So, rather than just showing you perfection, let’s nitpick something else.
So next, we’ve got an openwater swim. This one is an interesting openwater swim – and one I highlighted up above in the openwater swim video. I like it because it’s actually a fairly complex swim track. What you see here is the Fenix 5 on my wrist, the Fenix 3 on the swim buoy trailing above/behind me, and then the Suunto Spartan Ultra as well in the mix (it got started late, but we can still look at the track from that point forward). Here’s the overall track.
Let’s zoom into the first 1/3rd or so, and see how that looks.
You can see below that the smoothest is the purple line on the swim buoy, however the Fenix 5 is reasonably close to it. It bobs a little bit to the side here and there – though not a massive amount. This is common for openwater swim tracks as it’s not quite as precise as being above water the entire time.
Next, we’re looking at the middle section (passing another pier), when I properly started the Suunto Spartan Ultra. You can see that in general the Fenix 5 and Fenix 3 maintain the same dance. The swim buoy laden Fenix 3 is smoother of course, but the Fenix 5 is pretty darn similar. The Suunto Spartan Ultra isn’t really competing at this point. I don’t know what it’s doing, but it’s been a continual problem for me in OW swims. Suunto now has the unit and is trying to figure out what’s up with it.
Next, this last part where I come into this sheltered area behind the break wall. I selected this route on purpose, specifically because it was complex. And the two Garmin watches actually did quite well at mirroring not only each other, but also my exact track (interestingly, it’s here that it’s obvious the Fenix3 was accidentally in smart recording mode). In fact, technically the Fenix 5 actually correctly cornered the last turn around the rocks a bit more perfectly.
If we look at the final distances, here’s where they stand:
In this case the Fenix 5 had an overage over the reference track by about 180 meters. That’s a tiny bit more than I’d like to see (ideally I want it +/- 10%), though, it’s in the ballpark for openwater swim units. Note DO NOT LOOK AT the distance for the Spartan. Remember, that was started 500m into the swim (i.e. 1320m + at least 500m). So it’s already added a bunch of extra distance; obviously, it’s way off.
So overall, it’s not too shabby. I also included another two openwater swims in these sets down below – which gave comparable (or slightly better) results.
Note that I’m just highlighting the above three GPS data sets, but everything else is below in the table. I picked the above three because I felt that covered the most varied of conditions – and were also representative of what I saw on the whole. Some days/areas were slightly better, and some areas/days slightly worse. But nothing in terms of major outliers.
Here’s a table of all my activities on final or near-final software from the last 2-4 weeks. Note that in general, I’m excluding activities where I didn’t have multiple devices, or excluding activities where GPS isn’t involved (i.e. indoor treadmill runs or similar). As well as stuff from earlier beta firmware versions.

Sensor Support (ANT+ & Bluetooth Smart):
The Fenix 5 series is the first Garmin unit to not only support a slew of ANT+ sensors, but also now supports Bluetooth Smart sensors. Previously Garmin would only utilize the Bluetooth side of the house for connecting to your phone via Bluetooth Smart. Now however, you can connect to both ANT+ and Bluetooth Smart sensors, assuming both follow published standards.
At present, the Fenix 5 supports the following sensor types:
ANT+ External Heart Rate Sensor
ANT+ Cycling Power Meter
ANT+ Cycling Speed-only, Cadence-only, and Speed/Cadence Combo Sensors
ANT+ Running Footpod
ANT+ Gear Shifting Profile (SRAM RED eTAP/Campagnolo EPS)
ANT+ External Temperature Sensors (Tempe)
ANT+ Lighting Sensors (Garmin Varia/Bontrager lights)
ANT+ Radar Systems (Garmin Varia Radar)
ANT+ Remote Display (Varia Vision heads up display)
ANT+ Muscle Oxygenation Sensor (i.e. Moxy/BSX)
ANT Shimano Di2 Gear Shifting Profile
ANT Garmin VIRB Action Camera Control
Bluetooth Smart External Heart Rate Sensor
Bluetooth Smart Cycling Speed-only, Cadence-only, and Speed/Cadence Combo Sensors
Bluetooth Smart Cycling Power Meters
Bluetooth Smart Running Footpods
Phew! Lots of sensor types!
Now, the most important wording I noted above was ‘follow published standards’. On the ANT+ side, this means either following specific adopted ANT+ profiles (i.e. the heart rate sensor or gear shifting profile), or in a few limited cases, following company-specific standards. For example, Shimano Di2 doesn’t technically follow the ANT+ gear shifting standard, rather, they’ve done their own thing. But they were the first to do that thing, so everyone supports it anyway.
Where things get messy is private/extended variants of standards, especially on the Bluetooth Smart side. For example – running dynamics. There is no standard on either ANT+ or Bluetooth Smart for running dynamic type data (i.e. vertical oscillation, ground contact time, etc…). Instead, Garmin uses private-ANT (just like Shimano does for Di2). And other companies like Wahoo with the TICKR series use private methods over Bluetooth Smart. These aren’t compatible. Meaning that you’ll get base heart rate data – but you won’t get any running dynamics stuff when using a non-Garmin strap. Maybe some day, but today is not that day.
The same is true of offline data, meaning the ability for a heart rate strap to cache/save data when not connected to a watch. Garmin uses this with the HRM-TRI/HRM-SWIM heart rate straps to save data while you swim, because it can’t send that data to the watch through the water. When connected again, Garmin uses the standard ANT+ ANTfs offloading capability to allow a watch to download that data. This is a published standard (and has been for more than half a decade).
However, others don’t follow this standard, and there is no equivalent published standard for offloading fitness data on Bluetooth Smart. Thus other companies do it differently. For example, both Polar’s new H10 and Wahoo’s TICKR-X can save data offline, as can Stryd, Suunto, and 4iiii heart rate straps. But none do so the same way on Bluetooth Smart, let alone utilize the ANT+ ANTfs standard for offloading.
Said more simply: You’ll need a Garmin HRM-TRI/HRM-SWIM strap to download data. And you’ll need either a Garmin HRM-TRI or HRM-RUN to get running dynamics.
Of course, folks could pressure both sides of the equation to support other standards. For example, folks could pressure Garmin to open up Running Dynamics to be an ANT+ standard for a variety of efficiency metrics (nobody has tried harder to pressure them to do so than I). And inversely, folks could pressure companies like Wahoo and 4iiii to support ANTfs offloading of data from the strap for offline access.
Finally – some might wonder if you can use Polar’s H7/H10 and other like straps that transmit heart rate signals underwater live, to do so to the Fenix 5 (underwater). The answer no. That’s because while underwater the Polar device doesn’t use Bluetooth Smart to connect to these straps, but rather an analog frequency (the same one used for gym treadmills and such), which Garmin doesn’t support.
Here’s a simplified FAQ section, since I’ve seen about 1,328 questions about this:
Will the Garmin Fenix 5 support running dynamics from my Wahoo TICKR strap?
No, see above for details. It will read the heart rate data just fine.
Will the Garmin Fenix 5 connect to my PowerTap P1 pedals via Bluetooth Smart?
Yes, they can. You’ll connect both sides (Left/Right) and the Garmin will properly track left/right balance. However, because there is no standard for Torque Efficiency and Pedal Smoothness on Bluetooth Smart, you won’t get those unless you connect via ANT+. The general guidance of *every* power meter company I talk to in the industry is given the option to connect your power meter over ANT+ or Bluetooth Smart, always choose ANT+.
Will my power meter work flawlessly over Bluetooth Smart?
I’m just gonna be straight about this now: This will continue to be a mess. Garmin has done a pretty good job in getting compatibility working for the dozen+ ways that power meter companies have adopted the Bluetooth Smart standards in power meters. In the few BLE power meters I’ve tested, they’ve worked. But I haven’t tested every firmware version of every unit out there – and I can guarantee some don’t work. It sucks. A lot. Garmin isn’t the only one shaking their head. Everyone is. Different companies handle it differently. Suunto has tried as well to just ‘make it work’ as quickly as possible, while Polar seems to drag its heels on making things work. Everyone I talk to in the industry here about this topic truly sighs and puts their head in their hands in frustration.
Who to blame is a mixed bag, but either way, the consumer is left holding said bag. The good news is that every power meter out there except the Polar power meters support dual ANT+/Bluetooth Smart, so just use ANT+ and don’t worry about it.
Will the Fenix 5 connect to my Polar strap underwater?
No; said Polar strap uses analog signals to broadcast underwater. Garmin doesn’t have that hardware in the Fenix series to connect to that.
Does this mean the end of ANT+?
Not likely. I do think it applies pressure to ANT+ though to maintain relevance, but I think they can do that through things like standardizing running metrics and stuff – thus encouraging companies to utilize the platform. But until the day comes where I can look back on the preceding 6-12 months and say that every Bluetooth Smart power meter (or cycling sensor) has worked flawlessly with every head unit (from a connection standpoint), then ANT+ will likely continue to do quite well.
Can I connect to my ANT+ FE-C trainer?
No, Garmin’s wearable lineup does not support connecting to/controlling via ANT+ FE-C. However, virtually all trainers that support FE-C also broadcast ANT+ Power/Speed – so you can still connect to those signals just fine. You just can’t control the trainer from the watch. For that, you’ll need another app/device.
Can I connect multiple Bluetooth Smart sensors?
Yes and no. You can connect multiple sensors to a Fenix 5 – no issues there. However, you cannot connect multiple devices to a single Bluetooth Smart sensor. So if you’re connected to your Bluetooth Smart heart rate strap with the Zwift app (on your phone), then the Fenix 5 will be unable to connect to it as well. That’s because Bluetooth Smart at this time cannot accept multiple master device connections.
Bluetooth 5.0 does resolve this (upcoming), but so did Bluetooth 4.1 – and nobody has adopted either from a sensor standpoint in the sports industry yet. ANT+ does not have these limitations, a key reason it’s used in gym/coaching scenarios today.
Bugs & Quirks:
I often include a section in my review about specific bugs and quirks seen in the product. From a software development standpoint, there’s often a fine line between a bug that needs fixing – and what the software industry calls ‘by design’. Meaning it’s not technically a bug, but rather something that’s designed that way (however sucky that might be). In my case, I’m going to call those ‘quirks’.
Given I’ve been testing a pile of units since the day it has come out, I’ve got boatloads of time on said units. Much of that time has been on beta firmware versions. In general, I’m drawing the line that I’m only going to cover bugs seen in the final production version of things. After all – that’s somewhat the point of beta – to rid itself of bugs. I have however been tracking bugs I saw during beta, and specifically validating those have been fixed in the production version.
Also, note that I’m specifically looking at issues *I’ve encountered* during swim/bike/run/ski/hike/daily use/etc… This isn’t designed to be the end-all-be-all of bugs that may exist in the product.
With that, here’s where I stand:
Bug – Connect IQ Issues with Stryd Running Power Meter: I get constant dropouts with the Stryd footpod using their Connect IQ Data Field app. Ironically I didn’t have this earlier in beta, but it surfaced in the last 3-4 weeks. At present this appears solved in the latest un-released beta, which will likely hit shortly. At least, it was resolved in my run yesterday (for the past month it’s been broke). I’ll cross this out once things publish to production.
Stryd Update (Aug 1st, 2017): This has slowly manifested itself more clearly to be limited to the Fenix 5/5S (but not the 5X or FR935). It also impacts a few other random sensors in edge cases, but is more obvious with Stryd. Stryd no longer recommends people use either the 5/5S with Stryd, and I agree. I’ve run countless runs with it and Stryd, and the experience just sucks as much as it has 6 months ago. It’s part of why I use the FR935 instead (I also like smaller watches). As for potential fixes, it sounds like that ship has sailed. Stryd doesn’t have much they can do from a chipset standpoint, and it sounds like Garmin pushed the boundaries of the chipsets in the 5/5S a bit too much from a reception standpoint. I asked for another update last week (July 27th) from Garmin on the issue, specifically asking if either a software or hardware update was possible, or if changes to hardware were being made. Here’s the response:
“We are aware that there are reports of ANT+ reception issues, particularly with some specific devices. Garmin is looking at ways to improve the performance, but there does not appear at this time to be a “quick fix” software update. We do anticipate future designs to improve support for identified third-party devices that are not consistently meeting expectations today.”
Translation: It needs a hardware update (and that’s based on talking to a fair number of people in the know). My bet here is that at some magical point in the future there will be a small but undeclared chipset change on the 5/5S. It’ll likely happen as quietly as the new manufacturer static testing procedures for resolving the Fenix 3HR altimeter issues (and why you don’t see those issues on other new units). And my bet is after that point folks can probably call in and ask for a swap of a unit without issue (like you can do now for those seeing F3HR altimeter issues). But I also could be wrong. They could just never update the chipsets involved and it’ll remain a broken scenario. The irony here being that Stryd is probably THE app that Garmin holds up most often as a Connect IQ partner, and they’ve essentially screwed them on their best selling and most premier device.
Bug – Drops in ANT+ Connectivity when Shimano Di2 Connected: This annoying bug manifests itself only when connected to Shimano Di2, which will cause near continuous drops of other ANT+ sensors (i.e. power meters, external heart rate sensors, cadence sensors, etc….). Note that this appears to be happening significantly less in the most recent software versions – but it is still happening enough to me that I can repro it. So I think they’re getting closer to fixing it.
Bug/Quirk/Something – Optical HR accuracy in outdoor cycling definitely leaves something to be desired. Running seems pretty good, outside of a few blips sometimes in the first minute or two.
Quirk – There’s no quick release kit: One of my top complaints about the Fenix 3, before they released one, and the same is true here. For a triathlon/multisport watch, it’s a pretty big omission. Hopefully, Garmin will be able to find a way to create a quick release kit, similar to what they eventually created for the Fenix 3. Obviously, this would likely block the optical HR sensor, but I think that’s a fair trade-off in a triathlon where you’re likely to be using the HRM-TRI heart rate strap for recording HR underwater anyway.
Now in some ways, what’s more important than the bugs I stumble on is how the company reacts to the bugs you stumble on. In general, Garmin has a pretty good track record of tackling software-focused bugs relatively quickly.
Where they have less than an ideal track record is tackling trickier bugs – such as one that seemingly popped up for some Fenix 3HR users this past fall – making their barometers pretty much useless. The company has dragged their heels for 4-5 months now (despite my constant reminders about the topic), and their most recent response is just as unhelpful. There’s a very real slice of the population who have units that just don’t work (there’s, of course, a far larger chunk of the population that are just fine). It’s these sorts of incidents that are less settling when they happen.
Hopefully though we won’t see any unforeseen major issues with the Fenix 5, and that any uncaught bugs are quickly squished. As is the case, I’m currently testing the next firmware version – which fixes bugs that while not impacting me, no doubt impact someone.
Product Comparison Tool:
The Fenix 5 is loaded into the product comparison tool. At this point I’ve consolidated the three variants into a single entry, since the tool focuses on features more than sizes. The variations are noted accordingly in the entry below. For comparison sake, I’ve placed it against the Fenix 3 HR, as well as the Suunto Spartan Ultra, and then the FR735XT. You can, of course, mix and match your own comparisons using the comparison tool here, thus adding products as you see fit.
Again – remember you can make your own comparisons using the comparison tool here.
Summary:
I think it’s fair to say that the Fenix 5 is the best watch Garmin has ever made. While it may not be revolutionary in terms of features, it’s more of a polished evolutionary update. After nearly three months of usage, there are very few items I can quibble about in terms of oddities or quirks. And the early feedback from all of you after you’ve had nearly two weeks of usage since Garmin has started shipping seems largely the same.
Certainly, there are little things I’d like to see changed – but those are actually mostly on the platform side. For example, the mobile app supporting route creation, or the ability to see better web/app trending on the new training load and recovery metrics. Similarly, if you come from something like an Apple Watch you’ll also miss the ability to get pictures from text messages on the watch. But that type of display/capability of course comes at a heavy price on battery life. Certainly not a tradeoff I’m willing to make yet.
And that’s a key thing to understand: Sure, the Apple Watch has a brilliant display that looks stunning. And it has many apps. But…it also lasts one hole whopping day of battery. Maybe two if you’re lucky. Watches like those from Garmin, Suunto and Polar are instead designed to last weeks and have battery for GPS activities over 50 hours. It’s just a different market. More importantly, they’ve got easy to use tactile buttons for numerous functions that the Apple Watch lacks (as do some Android Wear watches). Which isn’t to say there isn’t a place for an Apple Watch, there absolutely is. It’s just not on the wrist of a triathlete in an Ironman, nor on the wrist of someone on a multiday hike through the Alps.
In any event, I suspect that either the 5 or the 5S will become my daily watch going forward (I tend to like smaller watches over the larger 5X). The Fenix 5 has quick responsiveness, accuracy, and is easy to use. Simple as that.

Hopefully you found this review/post useful. At the end of the day, I’m an athlete just like you looking for the most detail possible on a new purchase – so my review is written from the standpoint of how I used the device. The reviews generally take a lot of hours to put together, so it’s a fair bit of work (and labor of love). As you probably noticed by looking below, I also take time to answer all the questions posted in the comments – and there’s quite a bit of detail in there as well.
If you're shopping for the Garmin Fenix 5 (5/5S/5X) or any other accessory items, please consider using the affiliate links below! As an Amazon Associate I earn from qualifying purchases. It doesn’t cost you anything extra, but your purchases help support this website a lot.
And finally, here’s a handy list of accessories that work well with this unit (and some that I showed in the review). Given the unit pairs with ANT+ & Bluetooth Smart sensors, you can use just about anything though.
This is a dual ANT+/Bluetooth Smart cycling cadence sensor that you strap to your crank arm, but also does dual Bluetooth Smart, so you can pair it both to Zwift and another Bluetooth Smart app at once if you want.
This is one of the top straps I use daily for accuracy comparisons (the others being the Polar H9/H10). It's dual ANT+/Bluetooth Smart, and in fact dual-Bluetooth Smart too, in case you need multiple connectons.
Seriously, this will change your life. $9 for a two-pack of these puck Garmin chargers that stay put and stay connected. One for the office, one for your bedside, another for your bag, and one for your dog's house. Just in case.
This speed sensor is unique in that it can record offline (sans-watch), making it perfect for a commuter bike quietly recording your rides. But it's also a standard ANT+/BLE sensor that pairs to your device. It's become my go-to speed sensor.
This wifi-connected scale will track your weight and related metrics both on the scale display and in Garmin Connect (plus 3rd party apps like TrainingPeaks). It'll also then sync your weight to your watch/bike computer, to ensure accurate calorie data.
The HRM-PRO Plus is Garmin's top-end chest strap. It transmits dual ANT+/Bluetooth Smart, but also transmits Running Dynamics & Running Pace/Distance metrics, stores HR data during a swim, and can be used without a watch for other sports. Also, it can transmit XC Skiing Dynamics as well.

Thanks for reading! And as always, feel free to post comments or questions in the comments section below, I’ll be happy to try and answer them as quickly as possible. And lastly, if you felt this review was useful – I always appreciate feedback in the comments below. Thanks!
First off, thanks for the incredibly in-depth reviews and the occasional giveaways! I have not been able to find the answer to this question about my Fenix 5 Sapphire:
Will the Fenix 5 have enough storage capacity, with 1-second recording, during a run/trail run, to record a full 50-mile or 100-mile ultra marathon? (Battery life is not an issue since I will be using a portable usb charger if/when needed)
I also haven’t been able to determine the maximum length (in time OR distance) that I can run before using up all the storage (I plan on using 1-second recording, and unsure whether I’ll have GLONAS on or off).
Hi John B. I don’t think storage for any single activity could ever be a problem. i just checked and my fenix 5 has still has all the activities going back to the first one on May 15 and it is Sept 21 today. Thats over 1000km of runs alone logged at 1s GPS polling.
Background: I’m still using my 910xt, a Garmin footpod and an ‘original’ Quarq crank. All this is working rather wonderfully. However I also have a desire to spend waste some money on a new toy;-)
However, noting that there is always a bias to people reporting problems, not ‘stuff works as it should, move along, nothing to see’ posts, I’m slightly worried about the Ant+ with the Quarq (given I’ve not got Bluetooth) and with the GPS (albeit I use a footpod for pace anyway). Note that my main interest in the accuracy is giving me running pace feedback, I’m less bothered about if when I get home I ran 14.5km or 14.8km. So should I spend or wait?
1: no idea,
2: My fenix 5x tends to wobble a bit( especially for fast paced runs), if you don’t really want/need maps on the watch I’d recommend buying the 5/5S/FR935. I personally still use my vivoactive HR for shorter races…
For cycling I cover more distance than running, and being on a bike I have a greater need for easy access to maps. It sounds like the 5x map is too much of a compromise, especially compared to the interactivity of maps on a smart phone.
Does anyone have experience of using the 5 connected to a smartphone for mapping navigation? Is this a much better solution compared to the compromised view and interactivity on the 5x, albeit being all on the one device?
Hi DC Rainmaker, thank you for your great review!!
I hope you can help.
I love my Fenix 5s, absolutely brilliant, but recently I just cannot ‘sync’ my activities/sleep/steps etc.
My IPhone 7 is paired with my Fenix5s because I get SMSes and What’s ups and can read them all on my Watch Screen BUT when I try to sync my watch with Garmin up to see stats on my Iphone or Garmin Connect, it says it’s synced but no activity has been recorded… no steps nothing… I get a comment: please check your device is connected by bluetooth and that’s all. I’ve searched for answers for hours but no luck.. I can’t work it out..
Even when I connect my watch to my computer with the cable, the data does not upload automatically to Garmin Connect website. Sorry for the lengthy message. Hope you can help or maybe you know who could. Thanks very much, Justyna (Greetings from South Africa!)
The lack of after sales service from Garmin is shocking. Since the Android Nougat update of my Samsung Galaxy A5 – Garmin Connect cannot “connect” with my mobile phone.
The forums are awash with similar complaints and Garmin is offering NO SOLUTIONS??
Can DC Rainmaker please inform your loyal followers that Garmin Connect is a total failure and the service from Garmin is nom existent.
I now have a USD899 watch that can’t sync or upload my runs???
Did you contact Garmin support? It’s unclear if you did.
Often times during major phone updates, Bluetooth pairings fail. Thus in most cases you can simply remove the pairings (from both the phone as well as the apps), and that’ll resolve that.
I’d be curious again though, what Garmin support said when you called.
I once bought a 910xt from China when living in Shanghai and found that it was an Asia version. At this time the watch’s firmware updates were done by Garmin China and were a long way behind the non-Asian versions. Do a search on the garmin forums and you will see thee is some frustration there.
The flip side is that the device works just fine and the internet is a magnet for complaining.
If it was me, and I had an easy choice (return with access to a non Asian version), it go for the switch.
If you don’t have that option. Don’t worry, it may never be a problem. ?
In short, the situation sucks, but for most people it’s not a deal breaker. I can pressuring Garmin on it, because there’s no good reason for the delays there (well, no good ‘acceptable’ reason IMHO).
Where it hurts most is things like Connect IQ updates (which weren’t around in the days of the FR910XT). Take for example the planned CIQ update on Nov 22nd, that unlocks various apps/functions (like Garmin Running Power). But it could be numerous months later until the Asian variants get the update. Will you get the update? Yes, almost always eventually. But the eventually part is the part that sucks.
Hey, I have the fenix 5, saphire. Question. When i run sometimes I look down and the background to my watch face is black, and then it is white next time i look. It isn’t because of daylight it just seems to be random. Is it HR related?
hello any one an idea , i can not update my garmin 5X to the newest beta version,
i download all the files copy them as recommended, but nothing happens, this is happening since version 5,8x
Thanks for a great review. I read somewhere that the Fenix 5 Sapphire battery does not last as long as the Fenix 5 regular. Is this true caused by wifi?
What benefit is the wifi really?
thanks
There’s one very annoying thing that also belongs in the “Bugs & Quirks” section.
I just upgraded from e Fenix3 to a Fenix5 and wondered why my morning wake-up alert keeps disappearing all the time. Following link also describes the issue -> link to medium.com
I have the gF5X and its great but not sure what happened since i updated to version 6 o firmware I am not able to install the latest beta versions, I copy them to my GF5X bu one i discount the device from the computer it is not updating,
and when i connect to computer again the GUPDATE file not there there anymore any idea??
Yes i use a MacBook Pro download The filé this is automatic unpacked in the download folder I copy it to the Garmin folder
Disconnect the f5 x and nothing happens just updating watch faces …
When I reconnect the f5 to the Mac the gcd file is not there anymore any suggestion ?
I’ve been reading rumors about Garmin possibly releasing a slight upgrade to the Fenix 5 in January that doesn’t seem to be the Fenix 6 (Fenix 5 Plus?). If that is the case, would you recommend to those that are looking to purchase their first watch to hold off on the Fenix 5? Granted, it’s entirely speculation and you may have more information on the rumors than the general public. I’m very interested in the Fenix 5X, but there seems to be a lot of complaints over the GPS accuracy that has been reported across multiple blogs and forums. If this upgrade in January is legit, do you think it would be worth holding off to see if those issues have been addressed?
The data/tech and fitness junkie in me is getting real antsy to buy this watch. Haha. I hope to gain your input on this. Thanks.
Or you could get the Forerunner 935 which has the same internal hardware and software, but a different case which seems to cause far less problems in terms of ANT+ and BLE sensor connectivity.
Hi – great review…I have a question regarding the swimming – If I swim in a pool and do different strokes for example…200m backstroke and 400m freestyle – will the Fenix 5 pick this up and differentiate between the two? And show in my post swim data?
The elevation it tells you is a mix of barometric and GPS. For short term changes it’s mainly barometric, but it automatically re-calibrates off GPS on longer time scales.
I don’t know of any way to get it to tell you separate numbers for GPS and barometric.
This is a review of a million words, but did you really test the watch?
I bought it on Monday…and been suspicious about it’s accuracy since second one!
Yesterday I spent a full day outside in the cold:
14806 steps performed or 12.3km…
This helped to make 308 active calories…cannot be right, I am a 83kg man…
Hearth rate is always slow to catch up also in running mode;
Fitbit with products that cost a fifth is more consistent.
Also if I understand HR may be a work in progress, calories calculation is a simple calculation, cannot pass on this one, really bad.
This morning after one full hour of breakfast making and washing dishes, it accounted 3 active calories…like making a toilet break while sleeping.
I just updated my Garmin Virb basic and was playing around with it and my Fenix 5 Sapphire 47mm. Before it wouldn’t pair with camera for remote control but now it does. I just received an update for the camera and added it plus an update for the watch some time back. Apparently they have added this functionality. Just when I was going to get a new camera for this seasons snowboarding Garmin had to go an fix an issue. Well it saved me some money so now I can buy the a new helmet.

Just switched from Fenix 5 to Fenix 5X Sapphire, could you confirm that Vibration on 5X ist definitely weaker than on regular 5, or maybe I have a faulty modell?
It seems that the Fenix 3 can only store up to 30 courses on the devices (I cannot succeed in storing more courses, anf I have the latest current FW 8.50).
Is this limitation also on the Fenix 5 series, and more specially on the 5X ?
Thanks
However my Fenix 3 has currently 30 fit files stored in the COURSES folder.
I don’t know if there are any differences between ‘courses’ and ‘routes’. On the device they are named “courses”; however in the link you provided they mention “routes”.
Anyhow, I cannot add more courses on the devices… the limitation seems to be 30 courses, and not 50 as described…
Thank you for the review. However on one aspect you have put me on the wrong leg.
I do lifting and cross fit. I like to follow my HR especially when I do HIIT with weights. In these circumstances the HR doesn’t work at all. It’s not even close. The needle just doesn’t move. I can work my butt off but my HR will not raise above 100 which is definitely not the case.
You have any advice on that? I already regret that I bought the watch.
I picked up the Fenix 5x, primarily due to this detailed review (thanks!). I tested it out last night and was very pleased EXCEPT for the optical HR. I was doing hill sprints (8×30) and I live at 7,300 ft and the HR was waaay low (130bpm). I adjusted the watch to make sure I was below the wrist bone, tightened it, removed & put on other wrist, etc. But the HR was always low.
I really want to believe in the optical HR tech but I feel like out of the gate it’s wrong. Any thoughts? I really do not want to have to return the watch. It was cold last night (upper 30s) and my arms are obviously moving while doing hill sprints. Could this impact it?
If I go back to a traditional chest strap, what would you recommend for brands?
Any guidance would be greatly appreciated. Thanks!
I have not read all the post but in the review shall be added some test of Optical HR with HII Training or racquets sports…. seems that Fenix 5 is a poor performer.
The HR measurement is a base for a lot of calculations an data. Calories, peak performance, VO2Max and training effect. If it doesn’t work properly it becomes basically useless for measurement of training progress.
The optical HR is rather poor to my opinion. I do regret I bought the watch!
Something else funny. I already had at least 3 times that the phone tells me to move while I am walking. The thing is clueless obviously. Or I am an angel hovering above the ground.
I haven’t seen any comments or advice from the rainmaker ass well…
*Posted on Vivoactive 3 Review also*
Ray – great review as always. Thanks for the CT discount for VIP membership!
Can you post some pics comparing the VA3 to the F5 series? I am really curious how it compares. I am on the fence between the VA3 and the F5 Sapphire (upgrading my Vivosmart HR+ and want to stop carrying my Garmin 1000 on trips just to record gym gym stationary bike rides with my HR monitor).
First off…Ray, thanks for all your work and great reviews.
My Fenix 5X works well when at rest & for easy, short runs. But anything over ~45 mins, or at higher intensity and it seems to hit a ceiling and not register HR above 145. I’ve worn it with my Fenix 3 and chest strap (both watches set up with exact same profile), often seeing the F3 in the 170s but the F5 “stuck” at 145. This doesn’t always happen, at times the F5 will show higher HRs. But I can’t get close to recording a max HR with the F5.
I’ve tried wearing it as tight as possible, different positions on my wrist, and changing wrist (and adjusting the setting) but all with the same result. I only bought the F5 because I hate wearing a chest strap. If I could I would return the F5 and continue to use the F3. I can’t recommend this watch IF reliable HR measurements are important to you. It is a good watch 90% of the time, but it’s the 10% failure when I really need it that is frustrating.
I agree. 90% is not good enough if 10% does the damage. I have the same issues. I bought it to get rid of the chest strap. Paid good money for it and it just doesn’t work. I can get my HR above 100. It’s a joke.
Strange problem as you describe, I do not recognize this behaviour. During my runs I see regular values higher then 170. I compared teh values during a run with my old Suunto Ambit 2S watch with HR-strap versus the Garmin 5S. It’s not 100% exact but close enough. The average numbers were very close, the graphs were almost the same. Did you already google or contact the Garmin support ?
By the way, today i was gardening, i think the OHR isn’t precise, i felt my HR was sky high when did some heavy works…the OHR diplayed only 94 hr…this wasn’t right.
—
I think for sports you wil always need to wear a cheststrap..
—
Finally, as for wrist OHR, in general it doesn’t work as reliably (across most devices), when you have tools/objects in your hand with a tight grip. Sorta of a reality there unfortunately with much of the sensor tech today (wrist-based).
—
I’d be surprised if the OHR could keep a reliable measurement though tennis motions.
—
I’ve been using the Fenix 5 for a couple of days now. Unfortunately, I cannot make the OHR sensor providing me with useful information. The HR reading is completly off the chart. I tried everything – I even shaved off the hair under the watch. It didn’t help.
Check out the picture attached. I did 10min uphill intervalls and the HR does not correlate with the effort at all.
—
I’m having some difficulties with the ORH. In addition to some of the expected issue flagged in Ray’s various reviews of Garmin OHR watches, such as difficulties tracking sharp intervals and some issues with road cycling, I’m finding random spikiness and unreasonably high readings in what should be less challenging situations. This morning I recorded my normal morning walk to work as an activity and uploaded to Strava. This was a downhill walk at a pretty constant pace. I have a pretty low RHR, and I believe that my HR during this walk is typically in the 70-90 range. The HR graph shows several sharp spikes, into the 120’s with gradual declines. There is no way my HR ever got that high and the shape of the graph is entirely implausible.
—
I do have to say that oHR just doesn’t work for me (haven’t had a single run without issues), while for many other people apparently it’s great.
—
I won’t be using wrist-based OHR because it is too unreliable for me,
—
I also had my first workout with the new device today, a 4×4 interval session on a treadmill. The heart rate was way off in the intervals. During the first two intervals it was off by 20-25 beats, and in the last two it was off with 10-15 beats. I tried to change the position of the watch during the workout, but the result was just as bad. During the resting periods it took the watch about 20-30 seconds before syncing with my HR again. I know intervals are tricky for OHR, but at some point during 4 minutes of hard intensity, it should be able to get it right!
HR inaccuracy is one thing – especially when it’s variable. But the person is saying that no matter what they do they can’t get the HR to show over 145, which is actually rather unusual.
Optical HR accuracy depends on many factors, a lot of them being how a person wears the device and uses it. But even then, sometimes there are issues – just like sometimes on chest straps there are issues. Anyone who says either is perfect is kidding themselves. Some companies are better than others, and anyone who lumps all optical HR sensors into the same bucket is also kidding themselves.
Like it or not, what I tend to see in real-life running/riding with people that use optical HR sensors is that most wear it wrong. Most wear it too lose (flopping around), and right atop the wrist bone (also bad). Certainly, some wear it right and get issues (as I even showed in this very post). But with 1,600 comments on just this post alone, I’ve long since given up on trying to reply to every optical HR sensor bad-moment with the list of how to try and troubleshoot it.
I have solved my HR issue with a Scosche OHR band around the lower arm. It’s working fine. It also proofs to my opinion that the OHR of the Fenix5 just sucks. I have worn the watch on exactly the same place (holding it nicely in place by an neoprene elbow support which I used to support my joints and ligaments during training). It still doesn’t give the results. It’s too slow as far as I can see it. I think the sample frequency icw perhaps the strength of the less is just not good enough.
Anyway I have serious doubts about the OHR of the Fenix5.
And is not a optical Hr problem, my polar M600was perfect in recording Hr during high intensity sessions. Running is ok but other sport can’t be recorded properly… GARMIN support is even not responding to my questions….
I found some more flaws this morning. It’s no recording sleep data. Not so imported but it just doesn’t pick it up although I have been wearing the watch during the night.
>>In any event, I suspect that either the 5 or the 5S will become my daily watch going forward (I tend to like smaller watches over the larger 5X). The Fenix 5 has quick responsiveness, accuracy, and is easy to use. Simple as that.
Fenix 5 wrist heart rate inaccuracy in Stand Up Paddling.
At the start of the session the device reads the correct heart rate but a couple of minutes into the session the heart rate reading drops and stays at a level of about 37% of max heart rate for the entire session, whereas it is in reality about 75% of max as measured by my 920 with chest strap.
I’ve tried tightening and loosening the wrist strap but it make no difference.
Any insight on this issue?
Sapphire glass or no sapphire glass? I am wondering if the cost upgrade for the 5S makes sense. I have a few knicks in the bezel of my old 235 and 220, but nothung overly noticeable. I am a data nerd, so am thinking the Fenix is best, but am very interested in protecting my investment. I’ve never put a screen cover on my phones and haven’t had any issues. I only keep my watch for a couple of years, have been lucky to be able to upgrade, I just don’t know if it’s with the cost. (Plus I like the black and silver best!) Plus I wear it every day, since I work at a running store.
I made the choice for none-sapphire glass and the black-silver version. It looks very nice even as a regular watch. However I put a screenprotector on the glass to avoid accidents happening. I’m also very carefull but my previous smartwatch had some scratches (on the screenprotector) due to unfortunate scratching a wall.
For me the price difference is too large (despite the additional band you get) and the black version looks the same as the FR935 (which is cheaper but has same functionality in plastic case).
I hope my two cents help you make a choice.
My husband likes to hike and hunt. He has gotten lost a few times in the woods. Although he obviously finds his way back, I’d like to buy him a watch to make it a bit easier. I am guessing the Fenix 5X won’t help much, since he is always off the beaten path? Is there an app on any of the watches that can help him track where he starts walking and then lead him back there when he is done?
He also runs and works out every day so I’m sure he will appreciate any of the Garmins. Any recommendations for which one would be best suited for him wandering in the woods?
The whole 5 line has a navigation feature called “back to start” which would help. The 5x would have the additional advantage of a map for context where the 5 and 5s would just display the track.
In one of the recent beta firmware F5 updates (and subsequent up to software version v7.00 BETA) there was a BTE/ANT/SNS firmware update to v5.30. Does this update mitigate ANT+ reliability problems?
No change there. Sensor hub stuff is generally just very minor tweaks behind the scenes. I don’t expect to see any mitigation at this point to the ANT+ reliability issues.
In addition to this new sensor hub firmware, there are release notes on BETAs just prior to v6.00 RELEASE that indicate changes to ANT+ power management to improve reliability.
I reached out to Stryd support who indicated that they have made a modification to the Stryd firmware to increase the transmition power of their device and Garmin has made some tweaks on the Fenix 5. “I think those two factors have mitigated the issues that arose earlier.” The net result is that they are currently not getting complaints about dropouts from their F5 customers.
It makes sense to me that there could be a physical design problem with the F5 RF that causes intermittent problems at the margin that could be mitigated by things like boosting transmition power, scaling back aggressive power management, and possibly tweaks at the protocol level. While not fixing a physical problem they could make the marginal difference between flaky dropouts and reliable.
It seems like there is some reason to be cautiously optimistic.
Do you still have an F5 and Stryd that you could test with the latest?
(I stated what I stated above, because Garmin has been pretty consistent in talking to me in saying they didn’t see any way forward on this without hardware changes. On the flip side, Stryd did have a technical solution for the specific chipset Garmin was using they believe could have made a difference. Garmin was hesitant on that for reliability reasons. Perhaps this beta is them winning a bit of a test to see what happens.)
Loved the review but unfortunately my Fenix 5 doesn’t record power consistently with my stages power meter. A work colleague has a similar issue and I have seen numerous forums discussing this issue. It seems Garmin are in denial. This is incredibly frustrating. I expect a 500GBP watch to work without a hitch and to be thoroughly tested by the manufacturer.
I had a look through some of the other comments but have you experienced any issues?
Stages have given me a brand new unit which I will test this week but I am not optimistic. If it still doesn’t work I will be sending it back and moving to a rival product.
This is the never ending blame game between Garmin and Stages here. Ultimately, there’s basically two ways to look at this:
A) No other power meters show this issue on Garmin devices, except Stages.
B) Most other head units don’t see this issue, except Garmin with Stages.
On item B, one should probably remember that when it comes to power meter GPS watches, Garmin outsells everyone else like 95:1 for GPS watches, so it’s harder to see those trends.
None of which really changes your predicament. Try pairing it on Bluetooth Smart instead, some folks have seen better luck there. While there are issues as noted in the review on connectivity to 3rd party sensors on the 5/5S, Stages is one that’s kinda been an issue for years across many devices. It’s generally agreed upon within the industry that the transmission coming off of a Stages power meter is less than most other power meters.
This generally fails for people on the wrist specifically because usually people using it are on tri bikes, and usually that means their hands are further forward, and usually against aerobars. Which usually means you’re body acts as a huge signal blocker (wrist), plus the aerobars and related cockpit goodness.
Not making excuses for either company, just explaining the reality of the situation that’s been this way for years.
I disagree with the statement ‘no other power meter show this issue with Garmin’. My ‘G3 Powertap hub’ drops in and out of my Fenix 5 too. I am not on a tri bike, I am on my road bike (size 56 so not overly large frame with a long reach).
I compare data with my 510 and it is sometimes way off. I never had this issue with my Fenix 3. So what I can say is the Fenix 5’s reception is pretty ‘crap’ in relation to the Fenix 3. It is disheartening and frustrating as I prefer the size of the Fenix 5, the straps are better (although, I could put one on the Fenix 3). I like the split between anearobic and aerobic during an activity and I like the 24hr heartrate (although, when I do a ‘proper activity’, I will use a HR strap as I know the HR in the watch is not reliable when doing intervals etc.. I expected that from the go)..
Anyway, first world problems.. Now the issue is, do I sell the Fenix 3 or the Fenix 5? Do’oh..
Continuing the dropout theme I get dropouts using the Garmin Tempe sensor.
All I here is:
Change the battery. Done it.
Reboot the Fenix 5. Done it.
Keep the two devices closer together. Tried it.
I wait untill the Tempe connects before starting the activity. During the activity it periodically drops connection and records data from the built in thermometer causing spikes in the graph.
I fall into your catagory of geek full of data and find this issue frustrating.
Has anyone had or even cured this issue.
Cheers.
Phil.
I get the same annoying issue with my 935. I’m pretty sure it’s a firmware bug and I’ve already contacted Garmin about it a while ago. Another annoying issue is that I have two Tempes and sometimes find that the watch will connect to the sensor that’s on my running shoe circa 30ft away through two brick walls, but not the bike’s sensor that’s just 1-2ft away. It would be great if I could prioritise a sensor for a particular activity, i.e., just look for the running Tempe when starting a run, and just the bike one when starting a ride. In terms of ‘curing’ it I’ve found if you go into sensor settings and force the connection to the appropriate Tempe I get no dropouts, however I’ve only done this three times so far as it’s such a palaver to do at the beginning of an activity, so it might just be a coincidence. Ray any chance you mention these issues to Garmin please?
DC Rainmaker, thank you once again for a great review.
Some folks mentioned they wanted to see more on the navigation features, and I have a step-by-step there (and more of a hiking based review) on my site here:
I purchased a Fenix5 as a one stop device – however adding to the dropout issues: For me, a Watteam Powerbeat and Stages. Both of which work flawlessly on other headunits, including other Garmins.
Interesting is the fact that BT is more stable than ANT but not 100% – and ANT is supposed to be Garmin’s own protocol!
Garmin support actually responded that they dont support 3rd party devices, and are more or less burying their head in the sand over it – despite marketing the device to support all of these features.
It’s more than BT coming off Stages is at a slightly higher signal strength.
The challenge is that the Stages unit signal is well known to be an issue (and has been for years). Combined with the lower quality reception on the 5/5S, it hurts.
Yes, I have connection issues Fenix 5 with Stage powermeter. And connection Garmin Edge 510 to Stage no problem. When I put Fenix 5 on frame of bike very near the pedals, than ok, if I put on the wrist and make distance between pedals and watches bigger, then connection failed. So I can use F5 on home , close to turbotrainers and pedals, because want estimate my VO max by Fenix 5, but after it will be not possible in the spring , when will start outdoor season. So it is all very sad, because I did`t find this issue before buying F5.
Hey folks, I just recently switched from the 735xt to the fenix 5. So there is one thing that drives me nuts: All my activities that I recorded with the 735xt had “Elev Corrections” enabled. For the fenix 5 they are always disabled and the discrepancy between the altimeter & corrected data is huge. Now, I don’t know which data is more acurate, but I want to compare my new activities to my old ones. So why can’t define the “Elev Corrections” for my fenix 5 to be “activateed” for all (future) uploads? I automatically deactivates the correction for new activities! So, Is there a work around? Thank you in advance!
I have a Fenix 5 inbound for my birthday (not sapphire). Does anyone recommend a screen protector? Do you really need it? I bought it from REI so it has a 1-year satisfaction guaranteed clause in case I wish I had the 5X or the 5 Sapphire.
I am mainly planning to use it as my primary activity & sleep tracker and to keep track of workouts, walking and hiking while traveling (2-weeks a month). I may start swimming this Spring as well.
Hi
On my fenix 5s do I use a screenprotector since about 5 weeks (24/7). It withstood hiking, training and a little swimming and showers. Better safe then being sorry. I bought mine on Amazon link to amazon.co.uk
They are a little smaller but this is helpfull in applying them or getting them off if needed.
Up untill now, no scratches.
The 5X’s optical sensor can’t do HRV during a workout (nor does it display raw HRV data natively). Perhaps there’s some 3rd party Connect IQ app that does something I’m not aware of for day to day use.
Hi Ray! Do you have any idea as to when Garmin will release a new watch to update the Fenix 5? I have taken so long to buy it, I don’t want to invest in it to see another model come out right after! Thanks in advance and happy holidays!
Apologies if this has been asked before, i just cant read through all of the above questions…sorry.
Is it possible to add an existing set of GPS coordinates (given to me by someone else) to my Fenix 5x? If so, how?
Thanks for the great review!! It helped me to decide between the Fenix and the Spartan.
Just received my F5 and started using it (I’ve been using a FR620 just to run and ride, so I will have to consider wearing a watch all day again).
Keep the great work and our lives easier everytime we need to decide where to jump next on our devices!!
Thanks Garmin – a christmas present I’ve wanted for ages.
on the latest beta we have: Added the ability to access ‘Broadcast Heart Rate’ from the Controls menu (Settings > Controls) as well as through the system Hot keys (Settings > System > Hot Keys).
no longer 42 key presses to connect HR to Garmin edge
This is my first comment. Over the last decade or so I’ve been relying on DC Rainmaker’s in-depth reviews to influence my purchasing decisions. Thank you!
Now how about the Tanita BC-1000? It has ANT+ but I can’t find anything about 5x compatibility.
Garmin stopped making watches that work with ANT+ scales some years ago (3-4 I think). However, I believe Tania does have a Connect IQ app that works with it (and on the Fenix 5), but I don’t know the details of how well it works.
I Just got the 5s and so far I love it but there’s one niggling little thing I can’t seem to change.
I like to use my watch to track the various gym classes that I take. Obviously when I am indoors I do not care about distance, speed, or GPS. However I cannot see any option in the default Indoor Cycling Activity to shut off GPS and stop reporting speed and distance. (I’m not going anywhere on a stationary bike).
I also created a custom activity called Class for a bodypump style class. I was able to get the watch to turn off GPS, and to only display the data I care about (calories, time, HR). But in both instances when I stop the activity it still gives me a distance displayed. Is there any way to cut that out?
I’m just really surprised that in many of the factory-provided indoor Activity types, that it’s got GPS on by default with no way to configure it to stay off by default during that activity. I don’t want to have to go into system settings and toggle GPS every time I start an indoor workout!
it’s also annoying when i go into the mobile app to see my activities summary for the day and I see “Indoor Bike : — mph —- speed 55:00 minutes” – ideally i’d love to just see time/calories/hr. Distance and speed are irrelevant (and unmeasurable) in indoor spinning!
I’m really curious about this as well! I currently have a VivoActive HR and want to get something new as they don’t make these anymore. During my gym workouts with the VA HR my watch displays Work out time and Calories burned. If there is a way to set this up on a Fenix I am sold. If not I don’t know ill stick with Garmin :(
It‘s on sale at the moment @amazon.de for 359,20 €
Price is 449 but black/grey has a 20% off coupon which is activated during checkout. Sold by amazon directly.
Thank you a lot for that tip!!
But one question: Is there a successor comming in the next month?! .. A Fenix 6? What are the rumors for that? What new features is it going to have?
I am not impressed with Turn by Turn on my Fenix 5X on trails and nature preserves. Do I have to get the 24K to get turn by turn and to help me discover and navigate trails and nature preserves? How can I explore these trails and find them then load on my watch so that I don’t get lost while on them? Any ideas on a website that helps with this or would the Garmin 24K topo maps and basecamp help with this. I now that many trails in Michigan are not found on the 100K topo. Thanks.
I have a fenix 3 hr. Turn by turn navigation works by picking up map metadata rather than recognising a sudden change in direction. I found this to only to work in urban environments and not on trails (at least not in the UK). You can build a route in Garmin connect and download to the device. It does not seem to support waypoints (the website now sports a clunky way of adding these after much criticism but it doesn’t work). You can use other route creation tools such as Strava (free) and copy the gpx download to the hidden newfiles directory but it ignores waypoints. Suunto does the whole navigation thing so much better (see my previous comments). The idea of maps on a watch is a gimmick. You just need a route displayed to indicate the direction you need to travel at the appropriate level of zoom. Look at a paper map now and then – hi res – enormous screen – colour – visible in direct sunlight – infinite battery life. Its safer and its fun! Garmin is only interested in marketing. Their strategy is to produce lots of device variants with lots of features to penetrate as much of the market as possible irrespective of whether they work properly or even at all. I use my Polar M430 for serious training and my old Ambit 3 for hiking at which it excels.
I have the non sapphire Fenix 3 which my dog now uses, strapped to her collar, for walks and canicross. She’s about as rough as you could get on a watch but it hasn’t scratched yet and never missed a beat.
I’m not the one that made the comment, but I’ve been strapping my 5X to my dog’s collar to see how far she goes when we go on off leash walks in a park full of other off lease dogs vs how far I go (usually 1.8x’ish, for anyone curious). I’ve been using hook and loop straps. Seems to work pretty well.
I have these collars link to amazon.co.uk and I unscrew the watch band pins and run it through like a normal watch band or for Fenix 6 onwards because they changed the pins (for the worst) I bought a little pouch that they sell on places like Etsy that are attached to the collar and usually used for a tracker but the watch fits perfectly. Both my girls have the 5 and as ML said great for seeing how far they go so most days I’ll do 10k and the Dalmatian will do 11/12 and the GSP about 14/15 but she once did 22k when we walked with another Pointer and we did 8k.
Thank you for the very useful review.
Do you have investigated about the Bluetooth range of Fenix 5? I’ve observed that its range is shorter with respect to the forerunner 235 and to polar m400. I’m referring to smart notifications between the phone and the smartwatch. In particular it loses the signal when the phone and the smartwatch are in different rooms, at a distance of 4-5 m, while the other watches are still connected. Have you observed the same behaviour ?
Thanks
Really appreciate your exhaustive product reviews, very helpful, well done. Question on Garmin Connect privacy.
Just got a Fenix 5 and bike sensors to replace my (don’t laugh) Polar 625SX. Initially loved the Fenix but now am totally spooked about privacy since the thing needs to be linked into Garmin Connect which looks like a Google data mining play once one looks under the hood.
Fenix is a beautiful multipurpose device I can use for training, competition and wear to work without looking like a dork BUT looks like everything I do from bike to bedroom is getting synced 24/7 to Garmin and then shared. Some digging and I find Garmin Connect code pings Facebook (graph.facebook.com) and Ad Trackers (tags.tiqcdn.com) even though I don’t use Facebook and I set Garmin Connect to private, private. So now Facebook and who knows who else has my phone IP and associated it with my device (if you have a phone IP you have a name). And Garmin Connect privacy statement references using personal data for marketing purposes and sharing with affiliates, etc.
Using free services like Gmail means Google will pretty much record and sell everything you do, that’s the deal. But after paying $800 for some Garmin gear last thing I want is all my activity mined and monetized via Garmin Connect. Remember when Lenovo got busted for embedding Superfish in laptops? Or when Samsung TVs had open mikes? That’s kind of how I feel now.
Any idea how much of our data Garmin is monetizing and any way we can stop it? Or alternatively if there is a desktop only option for the Fenix (similar to my old Polar with the desktop app) where all of our data isn’t sent to Garmin? I don’t use social media, zero interest in sharing, comparing, etc. just want my metrics. Any thoughts or insight would be appreciated.
IANAL: They appear to claim not to share your data with 3rd parties unless you connect to other services like Strava or use social media login. They do use Google Analytics and Azure analytics on the servers and HockeyApp crash analytics in the Garmin Connect app.
So they say but then why are they providing Facebook with my phone and watch IP even though I have set Garmin Connect to private? Also, privacy policy references service not for use by those under 16 so if the personal data is 100% locked down, why the disclaimer for children? Unless you opt out, Garmin most certainly shares your data and I believe even when opting out they still share (like my phone and watch IP address).
I’m not a conspiracy theorist but I am in the IT business so anything connected to the cloud basically is in play. Good summary here on privacy concerns with activity tracking devices – link to techcrunch.com
I’ve recently bought Fenix 5x after few happy years with ambit 3. I was amazed by how bad the web interface is. Specifically, I could not found any way to change watch specification (eg light on or off during workout). Does anyone knows how to set watch specification at the web interface and then sync it with the watch?
Lacking an F5 myself, I’ll go out on a limp and say that you probably should look on settings on the watch itself, all garmin devices I own can alter each setting on the device itself. Doing this by a web interface is taking a detour and may not work at all.
dear rainmaker
thanks to your review I bought the fenix 5s. i used to have a tom tom . dont get me wrong it did his job but now i can cleary see why this watch costs more. im super happy with it.
and besides the white color is beautiful
Simple answer to this most likely. How do I get to the music control widget while using the watch for a run? When I try to scroll up and down I just get the different run screens. Thanks in advance anyone!
1. You need to have installed the music controls widget.
2. To access the widget loop during a run, you need to HOLD the down button (assuming you still have the default hot key setup).
So far so good with my fenix 5 after a week. A few minor drop outs on with the tempe sensor, but Vector 2 Power Meter pedals seemed to work ok after a few rides and Scosche HR worked fine for my Sunday 4 hour ride.
Clarity of the lcd screen is noticeably better then the fenix 3, that certainly helps with my failing eye sight. It’s also the perfect size for my wrist. I eventually got used to the fenix 3 size, but this is better.
I’m also digging the stress metrics and increased HR data capture. Expensive as all get out, but I found one dirt cheap on ebay.
hi , is anybody having issues with Altimeter ? I have a fenix 5 and altimeter is completely off, looks like i have been on everest few times! i called garmin support here where I live and they are very aware of the problem … they proposed to replace it, but they are not sure i will not encounter this issue again, to the point that they said i could consider going for the FR935…
I had the same problem, altitude ranging from +65,000 feet to – 1,200 in the same spot on my brand new $750 Fenix 5 Saphire. I believe problem to be more likely related to barometric based altitude adjustment rather than GPS because these wild swings occurred during crazy weather here in DC; however, my issue was resolved by (1) removing all non factory watch faces and (2) calibrating altitude and barometer with GPS. Keep in mind if you have watch on ‘auto’ your altitude will be driven by barometer so big weather system comes flaming in and your elevation will swing accordingly.
I didn’t run a strict testing protocol but I am certain watch faces played a role because (1) when installed I experienced lag or non reponsiveness on some buttons/functions and other weirdness and (2) all problems disappeared when I removed the watchfaces (I know, post hoc ergo propter hoc but too much of a coincidence. Also try comparing your watch barometric reading with local weather station – pick an activity, add barometric pressure as a data screen, and then you can compare to weather station. Might not be exact because some stations may altitude adjust but should be in the neighborhood. Hope this helps.
I think it is a lot easier to find negative feedback on the Itnernet than the silent majority that are reasonably happy.
I have had a fēnix 5 saphire since May and I have had very few problems. The firmware updates have generally resolved issues that I have had and introduced new features.
I had one GPS track go haywire during a cross country race with GPS+GLONASS enabled and a clear sky with no obstructions. On that occasion the only other runner with GLONASS enabled (on a fēnix 3) also got insane results. I subsequently turned off GLONASS and never had another significant issue. I subsequently learned that GPS+GLONASS is probably best for use in a city with tall buildings to improve tracking where there are a lot of reflections and interference with the sky. It generally makes it worse with unobstructed sky.
I had the display freeze and become unresponsive during a fartlek session while running a beta firmware once several months ago and I thought I was going to lose data. It turned out to be entirely a display freeze and after about 5 minutes the watch recovered and I had data and a GPS track for the entire run that looked sensible.
The GPS tracks and mileage is reasonably accurate and comparable to TomTom, Fenix 3, Forerunner 25,Forerunner 35, Forerunner 235, and Forerunner 620 results that my buddies get. The 1km pace and splits are always reasonable (with the above one-time exception). The instantaneous pace is sometimes very wrong but will correct itself in a few seconds. I feel like there has been some improvement in this area probably using the accelerometer to smooth the pace. I’m located in Southern Africa with very few tall buildings.
Back around June or July on one occasion, I had course navigation telling me to turn into the wrong road maybe 100m too early. There have been several firmware revisions and that issue did not recur.
I find the wrist heart rate sensor to provide reasonable-looking results 99.9% of the time. Rarely, I will see a spike that seems questionable but I also have seen occasional wonky results on a chest strap. Overall, it is a win for convenience.
The barometric sensor seems to give reasonable results except when I did an entirely uphill mountain half marathon into a rain storm where the barometric pressure was falling due to weather while I was also climbing. In this case it read quite low compared to adjusted GPS net elevation gain in Garmin and Strava.
The temperature sensor on the watch is clearly affected by body heat and I don’t think it consistently provides accurate numbers within 5C.
I have fallen in a cross country race and tumbled and bounced the watch face off of a rock which left no marks. I also fell once on a steep muddy descent in the rain head and arms first into mud and rocks. My skin was torn up, there were scratches on the rubber strap, but once I washed the mud out of the watch there were no marks. I don’t think my old Forerunner 230 would have survived either of those events intact.
I easily get a full week between charges with doing activity tracking workouts daily, mostly outside with GPS enabled.
I don’t currently have any ANT+ or bluetooth accessories, so I cannot say whether I would have an issue with reliability of personal area network devices.
Also for comparison, I have some mates with TomTom watches and in the past year two of those have done either complete scribble GPS during a race or shifted the whole track by at least 100m diagonally so that it doesn’t line up with any roads. None of this tech is perfect.
I would be happier if the display were 30-50% more pixel dense but not at the expense of significant battery life.
Overall, although it is expensive and not perfect, I have been happy with the device. Enough so that I just purchased a fēnix 5s for my wife.
I’ve got one since mid November and have don plenty of runs and bike-rides. When compared to the Forerunner 735xt and my note 5 the accuracy of the fenix 5 is notecibly better! I’d say it’s the best performing gps-device that i’ve ever had.
I use GPS+Glonass and I did several test-tracks, i.e. zick-zack runs, “Writing-Runs” (trajectory represents letters & words), etc. The fenix’s performance is stunning and I could clearly “run words” within a 5m*5m-letter-raster.
So did I miss something?! What problems is the fenix 5 said to supper from?
Also: Since it’s CES now, what are the rumors for a fenix 5 (plus/titanium) update and/ or a fenix 6 models? What is expected to be new and when is it speculated to be released?
So you’re the one that got the functioning Fenix 5! But seriously, I love my new watch but GPS is all over the place and seems to be a common complaint based on the Garmin forums; however, being a new user I’m withholding judgement until I am certain I am using the darn thing properly. As per my previous post I have found conflicts with supplemental watch faces so have removed them all and now the watch seems to be running fine. Still a few quirks but these could be intentional, still learning the thing.
Aleander, I was attempting to reply to your comment and seem to have replied to the person with a barometric pressure sensor problem accidentally. See my comment to you in #1675.
As a scientist I know that no measurement is flawless – quantum theory tells us that. At a classical physical scale we do not always have the luxury of constancy in conditions other than the one under investigation and yet conclusions can still be inferred based on statistical analysis. A good example is the measuring of strains on a suspension bridge by applying a known perturbating force with a known period – the short term much larger effect of traffic is virtually eliminated as it is relatively random and the sampling period is long. The chance of a significantly smaller spread of values detected by feller for some devices is so highly unlikely to occur by chance we should discount this. Of course all the GPS watches are OK – depends on your needs. Trail running in the UK may require great precision to avoid missing a track and in my experience Garmin watches aren’t really up to this whereas Suunto and Polar are. Unreliable instantaneous pace may be an important issue for some. Getting rid of the longer GPS antenna for marketing reasons has an impact on performance which may or may not be important to an individual. Let’s not pretend there is none.
Neither fellrunr nor DC Rainmaker are able to test fo sample variability by having several of the same units. Anecdotally it does seem like there is significant sample variation, particularly in early production units. There have also been a lot of software updates and it isn’t clear to me if ConnectIQ apps and data fields can affect the overall performance of the device. (I suspect they can.)
Your UK trails must be much more difficult to navigate than the trails in the bush in Southern Africa. I know many people navigating ultra run trails in the bush using Garmin Fenix and TomTom Spark. The Fenix 3 is the most popular watch with the F5 trickling in. I only know one person with an Ambit3 and her watch died on the 21km group run I was on today. (I’m sure she just forgot to charge it.)
My real world experience is that all of the recent watches are pretty similar in performance most of the time. Sometimes any one of them may freak out without an obvious explanation.
In any case I think the testing that Ray has done tends to show the devices are all pretty acceptable in real world GPS performance.
“…it isn’t clear to me if ConnectIQ apps and data fields can affect the overall performance of the device. (I suspect they can.)”
They certainly can. A few months ago I put a ConnectIQ field (I think, I don’t remember what it was any more, could have been a widget) on my Edge 1000. From then until I finally realized what was happening and removed it, I had ANT+ connectivity problems which I had never had before. That Garmin permits an IQ thing to screw up a core purpose of a device is worrying.
It is a shame a third party site such as Strava is not able to provide this information. It has the luxury of a huge population sample of real world use and it knows which devices were used (though I don’t believe the sampling or recording rates). Segments would provide an ideal basis for comparison. I bet some companies would pay to keep this quiet! (if they have not already done so).
My only African experience is of running in the Sahel in W.Africa. If the bush in S.Africa compares then yes, running trails in the UK is far more demanding for a GPS device (though not as physically challenging for the athlete!) for obvious reasons (Very sparse vegetation compared to to lush nigh on temperate rainforest in S.Wales and a large number of very narrow trails).
Not sure why you mention someone not charging their watch – what is the significance?
My real world experience is that the world is flat, projectiles run out of impetus, particles do not exhibit wave like behaviour, simultaneity is not relative and moving clocks run at the same rate as stationary ones.
It is a good job some brighter sparks were able to see beyond the “real world” or we would not have atomic clocks, special and general relativity and …. oh yes, GPS which is based on these non real world concepts!
Ha! Yes, West Africa is very different. Terrain ranges from veldt, to vlei (wetland), to mountain and dense forest.
The real world I inhabit is actually an oblate spheroid. That means I have to deal with time zones and my international airplane flights travel in arcs. Quantum effects happen in my computers all the time and a practical application of Einstein Relativity allows instantaneous, cheap, and fairly precise geolocation.
I don’t see much practical evidence that any male or model of consumer GPS watch is dramatically more or less accurate than 3-4m for each measurement and ~3% overall. They are differentiated by other features and industrial design and branding. I’ve seen faults happen on different makes and models that were not repeatable.
Garmin’s breadcrumb navigation does, in fact, work fine.
So what this practically means for existing unhappy users of fenix 5 sapphire
(unhappy because of stryd incompatibility and generally dropout issues because of poor signal)?
incredible , after having had fenix3 changed 3 times as they all died, now with the 5 the barometer altitude issue.
i really want to like this watch , but they just don’t work. I have to say i never ever returned a suunto or a polar , never .
I think it’s just poor manufacturing. Great customer service though they are always ready to assist and give you a new watch, as i am sure they know they always have issues.
maybe spend a bit less in customer service and more in quality of manufacturing could make sense.
Too much is being read into that FCC spec item. Far too much.
The issue around connectivity has *never* been the antenna with the Fenix 5. It’s the specific communications chipset they selected on the 5/5S, they can’t get the power out of it they need for the range they want. By time they realized the extent of the problem, the ship had sailed. Antenna placement can change for a million reasons, most notably shifts in other internal components.
I’ve argued they should have paused sailing and addressed then, but alas, I’m not the captain of that ship.
at the end, the fact is that fenix 5 have serious flaws when is paired with different sensors (p1 pedals, stryd…). for example I have big difference of NP between 520 and fenix…
I cant work out if it is Garmin or Huawei who are to blame for the current bluetooth incompatibility with the fenix 5. Each one are blaming the other. Anyone got any inside info on the current situation.
I do swimming, cycling and running and I’m a bit confused with Garmin’s product line-up. For me, would there be any difference between a Fenix and 920XT ? Both seem good for swimming and running workouts (I use an Edge 520 on the bikes)
Is there any reason to buy a Fenix over a 920X, or vise-versa ?
The 920XT is a generation old. It’s a solid device but kinda clunky looking and doesn’t have an optical wrist HR sensor. There’s nothing wrong with it. Solid and reliable, lots of people I know use them for Triathlon up to Iron Man and Ultra running. You should be able to get a good price.
The FR935 replaces the 920. It has a round display and newer software. It supports the latest accessories and comes with optical HR sensor, but you will want a chest strap for swimming and cycling. It’s a Fenix 5 in a plastic case without the metal bezel and sapphire crystal option. The FR920 seems to have marginally better Bluetooth/ANT+ connectivity than the Fenix 5 and 5s (but not the 5x), which makes a big difference for reliably connecting to the accessories from 3rd party vendors that should be compatible. YMMV.
The Fenix 3 HR is very similar to the F5 but in a larger case. Main difference is the software is a little slower and the screen resolution is a little lower and less colorful. The F3 series does not support the latest ConnectIQ API for 3rd party apps. The Fenix 3 non-HR is more similar in functionality to the 920XT, but heavier andlooks a lot cooler. You can get the F3HR new at the same price as a F3 on Amazon, so I would not consider the F3 without the optical HR unless you are getting a steep discount.
What firmware are you on? I’ve been on a bit of a roll trying various Garmin devices. Just finished a 35km ride with my (new to me) fenix 5 Sapphire and I had zero drop outs.
Units used during the ride:
Forerunner 935, edge 810, edge 1000 and fenix 5 Sapphire (with firmware 7.60). All units with 1 second recording and Glonass off.
Paired to the devices were:
Tempe
Vector (2) dual sided power
Scoshe optical HR
When I compared all 4 activities in Garmin Connect, every single activity showed no drop outs in sensors (ok, 2 small drop outs from the tempe with the 935, but zero drop outs otherwise).
Ray, your thoughts on if Garmin may have solved some issue here with ANT+ connectivity? I was going to sell off the fenix 5, but now might move the 935 along.
Hi, what’s your view on the altimeter / barometer problem of Fenix 5? My device is absolutely crazy on that and this unit is already the third trial (thru RMA)?
Hi there. I was wondering if there are different versions of Fenix 5x Hardware out there. I mean, i wouldnt like to end up buying some really old version of Fenix 5x (first ones out there) which may have hardware issues.
I know software will be probable needs to be updated which is not a problem cause that works like a charm, but is there anything i need to know about hardware?
Do you have any idea why the HR monitor is “all over the place” after the firmware update on December?
A lot of people are facing similar issues. Heard anything? Any tips maybe?
Its really disappointing . I came back to garmin with top of the line watch after a 3 years pause with suunto cause I didnt like their software issues and they fail on basics.
One of the body’s responses to cold conditions is to divert blood flow away from the limbs and the surface of the skin, and restrict it to just the head and core (preserving body heat for the essential organs). As OHR measures changes in the light reflected back from the LEDs with each heart beat, reduced blood flow makes getting an accurate OHR reading from the watch harder.
The legs are probably OK, because they are working hard and generating heat, but blood flow to the arms would definitely be reduced in the conditions you describe. The additional wind chill from the higher speeds during the bike leg would make the body colder, but core temperatures may rise slowly when running again, which would account for the timing of the HR accuracy.
A chest strap is probably going to be a better option in those conditions.
Great info.Never thought of it this way
Though I am running in Greece with 15 degrees at a February night I’ll keep in mind the blood flow factor and the temperatures.
My initial watch used to be perfectly fine, but some weeks ago the Barometric altimeter started to go crazy showing constant changes in altitude. I got a replacement unit. It had worked properly for 4 days and then the same problem occured: the altimeter is all over the place on my peplacement device. Its going up and down from +20000m to -20000 within several hours.
Is this problem known? is there a fix? Recalibrated everything several times. Same problem on sw-version 7.60 & 8.00. After reinitialization same problem. I wouldn’t want to get a 3. replacement..
Since I have a lot oc custimization (activity-profiles and Data-field setups): Is there a possibility to transfer all the settings (i.e. activity-settings) on a new watch? Where is that settings file located?
I have the 3rd unit now and it has worked for two days now ?. I have no trust on this though. I have been following discussions on the topic and I am extremely disappointed that Garmin keeps radio silence. That is a shame. I would have hoped a statement from DC too, but maybe I have missed it.
Aleander, I had the same problem, altitude running from +65,000 feet to –1,200 in the same location. Try this – remove any non factory watch faces and compare your barometric reading to a local weather node to check your sensor (add Barometric Pressure as a data screen to an activity to make it easy to view) . In my case the third party watch faces were hosing things up. Removed them, did a reset, recalibrated, and now all’s fine. Also the Garmin logic in Auto mode tries to figure out if the barometric change is due to you changing altitude or the weather. This can be tricky on a long hill climb which can mimic a slow drop in baromometric pressure.
Just looked at the thread a bit, but hard to discern what’s going on as it’s been over the course of 8 months or so.
I’d start with eliminating 3rd party apps first, and then go from there.
As a general rule of thumb with any device from any company, I find that if someone goes through 3+ units in rapid succession, it’s almost always something specific to that person’s situation (environmental, settings, usage, etc…). Not blaming, just saying that’s the best place to start and kinda walk back troubleshooting from there. Certainly, there are the rare units with manufacturing defects (or the general 5/5S communication stack issue), but beyond that there hasn’t been much in the way of widespread issues.
Thanks. If you take a while and look at the issue for instance in Garmin’s own discussion forum, you might notice that this may be epidemic. I live in North-Finland and it is cold and dry, but I would expect the device to cope with that. Others have similar experiences in other conditions, I have noticed. My previous unit went crazy at the 1st training session in the woods. I was once for a decade at the company within the same business and know something about the devices, but I wouldn’t like to go back to those as I find Garmins much more lucrative from spex point of view. And from their outlook. I have had long discussions with Garmin Finland and their service is great, but either they do not have a clue what the problem might be or they cannot admit that because it is that epidemic. I hope my present unit stands with my cross country skiing and MTM in these rare extreme conditions.
i am on my second fenix 5 , and have exactly the same problem again. I am currently at 8915 mt of altitude according to the watch.
Garmin at least here in Switzerland is very aware of the problem , they suggested replacement or to switch to 935… it looks like an issue with the metal case… this watch is of no use for people like me that use it especially for mountaineering activities
Altimeter Problems in 3 fenix 5 devices.
I purchased a fenix 5 sapphire in mid-January, 2018.
I repeatedly hit the problems of the altimeter being inaccurate by orders of magnitude: 65000+ feet and 32000+ feet elevation readings…and the down to negative 12000 feet (in areas of about 200 – 4000 feet above sea level)
I already returned 2 fenix 5 devices that had this problem and will be returning the third one I currently have.
I have the latest firmware, have done re-calibrations, multiple resets and do not have additional watch faces and apps loaded.
I am very familiar and experienced with devices that use barometric pressure for altitude. I have never seen problems like this with other Garmin devices with barometric pressure based altitude on such as Garmin Edge cycling computers and the Garmin Montana handheld GPS units. Same with 10+ year old Suunto watches. I’m using the fenix 5 in same areas / use cases as the others devices.
Garmin support did not acknowledge any specific known or widespread problems with the fenix 5 altimeters and offered to replace the device yet again, but after 3 strikes I’m done. It would be great if we could get some type of statement on where they are on the root cause analysis of this problem. It is not an isolated instance given that some people who care about altitude functionality are reporting it in various forums (including Garmin’s) and are also seeing it in replacement units…and there are likely others who do not take the time to post.
Since altitude is one of the most important measurements and metrics for my activities, I will be returning this for good as I’ve lost confidence in the device and Garmin’s ability to solve this problem for this device.
I’m disappointed because I’m otherwise very satisfied with the overall functionality and form of the fenix 5.
My story is indeed similar and there are others. Besides that I’m disappointed with the product quality I am extremely sad with Garmin’s and its ambassadors’ silence. Anyone can see that this is epidemic, at least. I am not an engineer but have worked in a company making HRMs in North Finland and I know something about if the problem is in HW or in SW. I would be happy with a statement that we are working with the problem and you will get a solution as soon as it is fixed. Now we have to keep replacing units and listening before it to how the device has to be calibrated etc.
I had two Fenix 5’s with the same altitude issue. Switched back to 5x and it doesn’t accurately track my skiing speeds or HR. Skiing speeds ranging from 80-125mph on various firmware versions.
My 2nd replacement Garmin Fenix 5 replacement with a bad pressure sensor. Both this one and the previous one quickly glitched. I do think static electricity is zapping the capacitance based pressure sensor causing it to go to a reading of 0 millibars over time. This one has been on my wrist for 3 days only. Temp is —-, barometer and altimeter are —-. Watch altimeter climb today for hours to over 65k feet and then it stopped working.
And when you contact Garmin, they will either replace it without questions or, for the sake of formality and before the replacement, they give you the link to the calibrating instructions. Fair and reasonable.
Kari – I agree and feel Garmin has done and will do the right thing with respect to replacement. I would like to know what actual conditions are causing the pressure sensor to act the way it does. I have determined that the sensor is drifting (ie: it is still sensing pressure but for instance mine reads 589.1 mb (should be about 1015 or 1030 mb) so it has drifted a lot. If I increase pressure it responds (ie: increases) and the altimeter will drop or the barometer will increase. The problem is the ambient is jumping around much more than normal. Wearing a long sleeve shirt or removing a jacket (causes static electricity discharge) causes it to retreat from it’s real reading and creates what I call a new bias point that is much lower in mb. The watch tries to compensate by either increasing altitude or lowering barometer reading (depends on setting of watch and logic).
This is an issue with the circuitry and logic of the pressure sensor – it appears gradually change the values even though the sensor reading is pretty sensitive. It reaches a new bias and if one calibrates with that incorrect bias, stability of measurement is ruined.
Just while typing this with the watch on my arm it is down to 582.7 mb. A bad storm is 6 mb drop within an hour ….
Living in Baltimore MD, the temperature outside is 55 degrees and the humidity is normal today. Even though most heated buildings are dry, the Fenix 5 pressure sensor should be able to withstand typical static discharge, but that is not the case with the 3 I have had. The first one was the least glitchy, this one is the most. Comparing serial #s, the first one was manufactured in April 2017, these in November 2017. They are over 90000 units apart in serial numbers, so I know that there has not been a change in hardware or manufacturing process with respect to the barometer.
This may be a 3rd party problem – I am sure Garmin sources these from a manufacturer like Infineon – it is most likely the problem either with the sensor itself or the integration of the sensor into the device (ie: mechanical casing, electrical connections, power supply, data lines, logic, software drivers, etc.)
Problem seems to have hit the 5, 5S, 5X and 935 as well as the 3HR all with varying degrees. 5 seems hardest hit.
My Fitbit worn on the opposite arm still counts steps.
I bought mine in December so I have a lot of time to see if Garmin figures this out. I love the watch otherwise (if I was not injured I would be out running, but since I cannot run I am doing stairs every day).
Thanks Mark :-) Your analysis would indeed explain the issue. What I am still awaiting is Garmin’s statement, explanation or instructions on how to go around this. Coming from a similar background, I cannot understand or accept the radio silence.
I’ve had an unfortunate experience with Garmin using a Fenix2 and have not considered their products since.
That watch would crash through a ride or a run. Switching from sport to sport in Multi mode, crashed. If it ran out of space, it’d crash and was very difficult to connect to PC and free up space.
I went back n forth with Garmin while still under warranty and they were very reluctant at the time to help much or send me a new unit. Eventually they sent a refurbished unit only after they’d received the problematic unit.
Unfortunately the same started happening with the old unit at which point I just gave up and decided not to look at Garmin again from a product standpoint and a customer service standpoint. It worked for 3 months prior, barely worked thereafter and won’t even hold a charge now. I’ve not touched it since last Spring 2017. Junk.
So, having read this eval, I was wondering if anyone here had expressed similar issues with a Fenix 5 as I’m reluctant to fork out another $600+ (I’m in Canada) on a problem product and then deal with not-so-helpful support from Garmin
Hi Ray ,first thanks for your work I read your blog since many years.
I don’t understand though the environmental, usage , settings remark, I have had many ABC GPS watches and never had an issue with altimeter barometer .. I sent my second fenix 5 for RMA and currently using an old ambit vertical which has perfect altitude readings .
Apart for that I really like the watch , but for me altitude datas are very important .
Regards
A) Specific to a person and how they use/treat the gear
B) Specific to the region they’re using it in (such as weather that might include humidity/dry air/salty air/etc…)
C) Specific to what the person might be wearing (such as specific pieces of clothing that have a higher likelihood of transferring meaningful static electricity)
D) Some other random factor that’s unique to a given person’s day to day situation that causes and issue
By and large, most non-software tech bugs of all products after the first month or two tend to fall into environmental type issues. Meaning, they’re harder to solve because it’s a unique thing to that person/environment that can’t be easily repro’d elsewhere.
I’d specifically note the static electricity one as a very likely cause of breaking of altimeters. Certain clothing is far more likely to cause issues than other. For example, I know I’ve got one running tech shirt that for whatever reason always zaps me. Why? I don’t know. Some clothing expert could probably tell me…but I don’t know why that green shirt always does that.
The reason we know it’s not widespread is the numbers just don’t support that. By now it’s a safe estimate that Garmin has probably shipped between 750,000 and 1,250,000 Fenix 5 units. Roughly (based on historical trending of Fenix 3 units and such while getting more popular). If this was a huge issue that had hundreds or thousands of unique comments on those threads, then I’d be more concerned.
Instead, it’s still a totally sucky thing for those that run into it – but that means it’s not likely to be considered a widespread issue that everyone runs into. Obviously it sucks being on the wrong side of it, especially when it’s hard to figure out what causes it. But if a given person goes through 2-4 Fenix 5 units in a short timespan with the same issue, then that almost exclusively points to something unique about that person or their environment.
Ray, far from trying to have a discussion with you on sport tech, you a guru and know well what you talking about , but i am not convinced on this one.
i had many many gps ABC watches in the past 15 years, and never ever had such an issue where i would go from 15k mt to -32k.
the reason why i think many people don’t complain about the altimeter out of the hundred of thousands who own a fenix 5, it’s probably because they do not use this specific function . I live in Switzerland and I use the altimeter of course :-) …
the fact that Garmin itself on a phone call suggested to probably look at the 935 instead after a couple of RMA, to me looks quite obvious that they are aware of the issue.
I have zero technical knowledge but I do have many years of usage and again never one of my previous polar suunto or garmin itself gave me such a problem.
Still I like the watch and I hope the 3rd one will not have the same issue.
regards
Ray, your answer is fair, thanks. However, I cannot yet believe that this is not a bigger problem than you suggest. I have been using various Polar devices, and devices of another Finland based company because of some coop between those at some point of time in history and I never faced this. Further, if you design a device like Fenix 5, you simply have to take into account such environmental factors as you list. Fenix 5 is a device that should stand quite a lot in terms of environment and there are engineers who can reach that. I cannot make a hard claim but to my current understanding, Fenix 5 has design failure.
Curious if these altitude problems are occurring in GPS or UltraTrac OR offline when watch is in Auto mode and it’s extrapolating altitude via pressure changes (which can be waaaay off)? Also not clear if these problem watches have checked sensor accuracy with known values like local weather nodes and topo maps. Apologies if this was already covered or maybe I’m completely missing something.
My assessment as a first time Garmin customer and Fenix 5 owner is that the altitude problem, at least on my watch, seems to be the logic for differentiating whether pressure change is due to weather or altitude when watch is in auto mode. My barometer readings match the local weather node and calibrating altitude via GPS matches topo maps so sensors seem accurate.
I’m going by the Garmin book for offline (no sat link) use – calibrating altitude via GPS and leaving watch on Auto mode. Problem is that watch makes assumptions about pressure changes – slow and its weather, fast and you must be moving. Generally this has held true for me provided I calibrate every day and keep moving (or I stay still and the barometer is steady). If I don’t calibrate for a few days my home/starting point altitude starts to drift up or down 50’ – 100’ which isn’t unreasonable given the crazy weather that comes through Wash DC. And overnight I can go +/- 50′ – 100′ while asleep so that’s obviously weather.
When I first got my watch I too was getting +65,000 to -1,500 altitude swings. Removed non factory watch faces (I was getting button lag or no response on some functions), did a hard reset, recalibrated altitude and barometer via GPS and been fine ever since – when I calibrate at home I get the same altitude every time and high and low points on rides, runs, and drives are the same as well. But mix in some weather and long slow hill climbs I’ll get variations. Haven’t tried GPS or UltraTrack yet so maybe that’s where everyone is having trouble but so far all of my GPS calibrations have very closely matched topographical maps in the DC metro area.
But if folks are using GPS or UltraTrac and getting +/- 65,000′ variations AND their sensors consistently correspond to known values (weather nodes and topo maps) then I’d agree something going on. Just not on my watch except when I had the wonky watch faces.
I think A) might be the cause for my problems. Here is my experience:
Bought a fenix 5 last November. Everything awesome. After one month however, the fenix 5 froze, i.e. hung up during a long, cold trail. But it could reboot after 20min and continued recording. Same thing happened twice some weeks later during runs in very cold weather. And finally in mid January again the watch hung up while running but this time it never rebooted. I did not know better and simply tried the soft-reboot pattern and/or connecting to pc.. So I got a replacement. It had been working just some days and suddenly both the altitude- & barometer-drifting began followed by a temperature reading of “—“. Soon after the drifting began the watch hung up and was not rebooting, just like the previous watch. So I replaced it another time and the story repeated itself after a week with the 3. watch.
Now, however, I’m happy with that 3. watch, as I can confirm that a hardreset will make the watch work again and all the sensor readings will be perfectly fine. I searched for different button-press combinations on the watch to do a hard-reset and was able to enter the Test mode, which showed everything is fine with the watch’s hardware. Now it’s been working perfectly fine for a week.
Conclusion: The one constant thing on all the problematic watches has been a custom watchface. I’m not sure if the watchface really is the cause for the problem, but now I use the native face and had no issues so far. So if you happen to get the same sensor driftings/errors, do a backup before and try a hard reset. Hopefully it will work again. And get rid of the custom watchfaces.
Another thing: I think the garmin support is very good. they replace the units quickly by new ones. So no complaints from my side.
1) Ambient Pressure (AP) which is the “true” figure and which can only be seen in training modes
2) Barometric Pressure (BP) which can be seen in widgets and which is based on AP and calculated further based on weather etc.
In my faulty devices, AP was all the time between — and a high figure such as 10 0000. I live at sea level and it should be always ca. 980 – 1050.
If the AP is e.g. 20, the device assumes you are in the “moon” and you get a crazy high figure. If the AP is 100000, it assumes you are at the sea bottom. The figure of AP is the one to blame in this comedy.
If you in such a crazy situation calibrate your altitude with GPS, you get the right altitude, but just for a very short moment. The device starts “correcting” the figure immediately and you are soon again in the space or on the sea bottom.
Why the AP give crazy figures, I do not know. I hope it would be sw related, but I am afraid it is not. I think the engineers have simply ignored standard design steps what comes to testing static electrics tolerance. Now we have to avoid skiing in winter, wearing jumpers and keep washing the device in soap water every now and then.
I would not dare to use their diving instruments before a fair explanation.
Kari – For some odd reason one of your comments got stuck in the trash bin which appeared to have a ripple-on effect for your duplicate variant attempts. Not really sure why, as there’s nothing in it that’s SPAM/Trash worthy. Odd. Anyway, found it and fished it out. Sorry about that.
As the two previous commentators noted, I’d be curious if you have any custom watch faces or apps – and if so, if you’ve tried their steps. I totally get singular bad units, or even singular bad batches (or heck, even a few weeks of bad batches). But generally speaking when the same individual goes through three watches (especially from the RMA pool, which is the most random way possible of getting new watches), it almost always falls back to an issue that’s somehow unique to that individual.
Not trying to place blame that it should be your problem to untangle – but rather, just trying to help troubleshoot.
Hi again – I think one my faulty devices had an extra face, but at least the last one didn’t. It went crazy almost immediately. I have been thinking of what I do wrong or what circumstances may cause this, but the only thing I could say is the weather. It is dry and cold here. In winter and with the last faulty device, I did only xc skiing. Garmin asked me to test it for a while before the replacement – they wanted to have the file as well – and in those sessions I had my Edge 810 in the pocket and it gave right recordings. While the Fenix was at Garmin, I used my beta M400 and it gave right recordings. Also, I had the M400 on my wrist 24/7 those days exactly as I had my Fenix and M400 didn’t take schocks from anywhere. The AP / the respective sensor is the reason, but is it in the SW, HW or in some combination, I do not know.
I observed ambient pressure (direct pressure read by sensor) jumping around. The sensor appears to skew its’ baseline (generally dropping) when exposed to static electricity. I believe the sensor is capacitance-based. The ambient pressure should somewhat match current barometric pressure compensated by altitude. The actual barometric pressure – altitude compensated (maybe with some temperature compensation.
For me at a few hundred feet above sea level that number is usually a little over 1000 mb when the sensor is working correctly. Right now my ambient pressure is around 950mb but is fluctuating up and down (while inside a building). I get no measurement of climbing or going down 8 stories of stairs.
When it works correctly I could do stair climbing sessions and see the 6 flights and 6 descents done twice on the elevation chart of the activity. I don’t get any flights anymore with this Fenix 5 (3rd one).
This is definitely a widespread issue with the sensor (maybe bias gets messed up due to static discharge) or I am unlucky (3 for 3). Ruled out 3rd party apps this time.
I tried warm water with mild detergent as Garmin mentioned. Helped but can’t get the sensor to ‘settle down’
There is an ambient pressure connect iq widget that shows the true story of what is going on.
I have also had my last couple attempts to post not take (tons of typing)… Echos exactly what Karl and others are stating about ambient pressure sensor …. this is after soaking the watch for an hour and it sitting on the shelf all night. Ambient finally is recovering.
I have attempted multiple posts but they don’t seem to have made it here …. saw with with another person as well.
Yesterday I did a hard reset of my Fenix 5. I also did a 30 minute warm water with mild detergent (per Garmin’s web site FAQ) soak. I paired with my phone, but have not added back any connect iq watch faces, widgets, data fields or apps. I let the watch sit overnight off of my wrist. This morning I placed the watch on and went about my daily routine (actually at a hospital where my daughter is ….). The altimeter and barometer are working within reason all day with no large retreats. I am not looking at ambient pressure, but looking at barometric pressure it is reading in the 1010+/- range and the altitude is maybe 150 feet off (I have not calibrated it) but responding exactly as the watch should. I climb 8 flights of steps and I see the altimeter respond fairly quickly and accurately. I go back down steps and see roughly the original value shown. I drove home tonight and the elevation change roughly was pretty decent (no random ascents or descents) and the altitude at my house was maybe 160 feet off. I did calibrate the altitude (leaving the watch in default auto-mode) and all seems ok. We do have a low pressure system over us and the barometer is about 999 mb, weather channel states 1000.3mb. Right now the sensor is pretty darn accurate.
I don’t doubt the sensor is affected by static discharge, but maybe some connect iq widgets and/or watch faces are causing the sensor hub not to properly handle recovery from a glitch?
Are some of the Watch faces you download from GC throwing off these watches? In my case, I think it was really draining the battery, although I don’t know why. The watch face was pretty simple but had a steps counter and 1 or 2 other things.
Here is a probably slightly offtopic question, but still, I hope you can help:
I recently bought a PowerTap C1-Powermeter and I use it with my fenix 5. Everything works flawelessly and I already did several FTP tests. So I aim to train in powerzones and I’d like to show a smoothed %FTP- field in the fenix’s screen.
All I can find, however, is an instantaneous FTP-field, which jumps around like crazy all the time, rendering this datafield totally useless. So is there a way to show the 3s/5s/10s %FTP-average like it is possible to be done for the absolute Power?
Yeah, throw me on the list of people with huge altimeter problems. Been going on since I got the unit, and I’ve gone back and forth on email, but based on what I’ve read on Garmins forums, they’re not acknowledging the problem. Today, I’ve been on quite the roller coaster ride today with this watch. With the exception of its inability to connect to my stages power meter, it’s been phenomenal, but the altitude issues are abysmal. Yes, it’s cold where I am right now. Yes, I wore a synthetic shirt skiing all day today. Yes, it probably generated static. But that’s what I bought the watch for. Skiing, and hiking, and biking and running. And I live in upstate NY, so it’s often cold. Shouldn’t the device function during these activities? My fenix 3 never experienced this issue under the same conditions.
I’m on that list too. My first Fenix 5 went awry within a month. Warranty, got another, that one went wacky after a couple weeks. Now they are sending me a 5x, which they say doesn’t have the same issues.
Last week I went skiing… At the base of the mountain I was at 60k ft elevation, by lunch time I was at an amazing -520,000 ft.
Wow my best is 93,000 above sea level. Interesting that they gave you a 5X–did you ask for it or did they volunteer. I just soak mine every couple days–pathetic.

Hey DC,
First off, thanks for the incredibly in-depth reviews and the occasional giveaways! I have not been able to find the answer to this question about my Fenix 5 Sapphire:
Will the Fenix 5 have enough storage capacity, with 1-second recording, during a run/trail run, to record a full 50-mile or 100-mile ultra marathon? (Battery life is not an issue since I will be using a portable usb charger if/when needed)
I also haven’t been able to determine the maximum length (in time OR distance) that I can run before using up all the storage (I plan on using 1-second recording, and unsure whether I’ll have GLONAS on or off).
Hi John B. I don’t think storage for any single activity could ever be a problem. i just checked and my fenix 5 has still has all the activities going back to the first one on May 15 and it is Sept 21 today. Thats over 1000km of runs alone logged at 1s GPS polling.
Background: I’m still using my 910xt, a Garmin footpod and an ‘original’ Quarq crank. All this is working rather wonderfully. However I also have a desire to spend waste some money on a new toy;-)
However, noting that there is always a bias to people reporting problems, not ‘stuff works as it should, move along, nothing to see’ posts, I’m slightly worried about the Ant+ with the Quarq (given I’ve not got Bluetooth) and with the GPS (albeit I use a footpod for pace anyway). Note that my main interest in the accuracy is giving me running pace feedback, I’m less bothered about if when I get home I ran 14.5km or 14.8km. So should I spend or wait?
Does the Fenix 5 give a VO2 max estimate for cycling without a power meter?
Also, have you ever felt the 5x to be too cumbersome while exercising?
Thanks!
1: no idea,
2: My fenix 5x tends to wobble a bit( especially for fast paced runs), if you don’t really want/need maps on the watch I’d recommend buying the 5/5S/FR935. I personally still use my vivoactive HR for shorter races…
Are there longer bands available for the Fenix 5s other than Garmin?
For cycling I cover more distance than running, and being on a bike I have a greater need for easy access to maps. It sounds like the 5x map is too much of a compromise, especially compared to the interactivity of maps on a smart phone.
Does anyone have experience of using the 5 connected to a smartphone for mapping navigation? Is this a much better solution compared to the compromised view and interactivity on the 5x, albeit being all on the one device?
Hello,
I needed to ask if Fenix 5x can be used for diving upto 50 to 70 metres..
it will be ok ? or the watch will be messed up ?
Hi DC Rainmaker, thank you for your great review!!
I hope you can help.
I love my Fenix 5s, absolutely brilliant, but recently I just cannot ‘sync’ my activities/sleep/steps etc.
My IPhone 7 is paired with my Fenix5s because I get SMSes and What’s ups and can read them all on my Watch Screen BUT when I try to sync my watch with Garmin up to see stats on my Iphone or Garmin Connect, it says it’s synced but no activity has been recorded… no steps nothing… I get a comment: please check your device is connected by bluetooth and that’s all. I’ve searched for answers for hours but no luck.. I can’t work it out..
Even when I connect my watch to my computer with the cable, the data does not upload automatically to Garmin Connect website. Sorry for the lengthy message. Hope you can help or maybe you know who could. Thanks very much, Justyna (Greetings from South Africa!)
The lack of after sales service from Garmin is shocking. Since the Android Nougat update of my Samsung Galaxy A5 – Garmin Connect cannot “connect” with my mobile phone.
The forums are awash with similar complaints and Garmin is offering NO SOLUTIONS??
Can DC Rainmaker please inform your loyal followers that Garmin Connect is a total failure and the service from Garmin is nom existent.
I now have a USD899 watch that can’t sync or upload my runs???
Did you contact Garmin support? It’s unclear if you did.
Often times during major phone updates, Bluetooth pairings fail. Thus in most cases you can simply remove the pairings (from both the phone as well as the apps), and that’ll resolve that.
I’d be curious again though, what Garmin support said when you called.
Are you able to run (follow) a course and use a workout at the same time?
Not a problem.
Select the activity then long press the UP button, sellect navigation, choose yours course, press GO.
Sorted.
Hi Ray,
I got a Fenix 5X but the box says “ASIA VERSION” should i be worried? May I know what’s the difference with this and the US version?
I once bought a 910xt from China when living in Shanghai and found that it was an Asia version. At this time the watch’s firmware updates were done by Garmin China and were a long way behind the non-Asian versions. Do a search on the garmin forums and you will see thee is some frustration there.
The flip side is that the device works just fine and the internet is a magnet for complaining.
If it was me, and I had an easy choice (return with access to a non Asian version), it go for the switch.
If you don’t have that option. Don’t worry, it may never be a problem. ?
Hi Jase,
Thanky you very much for the enlightenment. This is very useful information.
Indeed, Jase hit the nail on the head.
In short, the situation sucks, but for most people it’s not a deal breaker. I can pressuring Garmin on it, because there’s no good reason for the delays there (well, no good ‘acceptable’ reason IMHO).
Where it hurts most is things like Connect IQ updates (which weren’t around in the days of the FR910XT). Take for example the planned CIQ update on Nov 22nd, that unlocks various apps/functions (like Garmin Running Power). But it could be numerous months later until the Asian variants get the update. Will you get the update? Yes, almost always eventually. But the eventually part is the part that sucks.
Hey, I have the fenix 5, saphire. Question. When i run sometimes I look down and the background to my watch face is black, and then it is white next time i look. It isn’t because of daylight it just seems to be random. Is it HR related?
hello any one an idea , i can not update my garmin 5X to the newest beta version,
i download all the files copy them as recommended, but nothing happens, this is happening since version 5,8x
any help is very much appreciated
marc
I do hope you uploaded that to Strava. Can you confirm if the GPS track was accurate for the jaunt on the nudist beach.
Love the info!
Thanks for a great review. I read somewhere that the Fenix 5 Sapphire battery does not last as long as the Fenix 5 regular. Is this true caused by wifi?
What benefit is the wifi really?
thanks
Hi Ray,
There’s one very annoying thing that also belongs in the “Bugs & Quirks” section.
I just upgraded from e Fenix3 to a Fenix5 and wondered why my morning wake-up alert keeps disappearing all the time. Following link also describes the issue -> link to medium.com
Crazy that they did not fix this by now!
Cu,
Wouter
Hello Ray , I am asking for our help please…
I have the gF5X and its great but not sure what happened since i updated to version 6 o firmware I am not able to install the latest beta versions, I copy them to my GF5X bu one i discount the device from the computer it is not updating,
and when i connect to computer again the GUPDATE file not there there anymore any idea??
Just to confirm, are you putting the .GCD file (unzipped) within the Garmin folder?
Yes i use a MacBook Pro download The filé this is automatic unpacked in the download folder I copy it to the Garmin folder
Disconnect the f5 x and nothing happens just updating watch faces …
When I reconnect the f5 to the Mac the gcd file is not there anymore any suggestion ?
Hey Ray,
I’ve been reading rumors about Garmin possibly releasing a slight upgrade to the Fenix 5 in January that doesn’t seem to be the Fenix 6 (Fenix 5 Plus?). If that is the case, would you recommend to those that are looking to purchase their first watch to hold off on the Fenix 5? Granted, it’s entirely speculation and you may have more information on the rumors than the general public. I’m very interested in the Fenix 5X, but there seems to be a lot of complaints over the GPS accuracy that has been reported across multiple blogs and forums. If this upgrade in January is legit, do you think it would be worth holding off to see if those issues have been addressed?
The data/tech and fitness junkie in me is getting real antsy to buy this watch. Haha. I hope to gain your input on this. Thanks.
Or you could get the Forerunner 935 which has the same internal hardware and software, but a different case which seems to cause far less problems in terms of ANT+ and BLE sensor connectivity.

Hi – great review…I have a question regarding the swimming – If I swim in a pool and do different strokes for example…200m backstroke and 400m freestyle – will the Fenix 5 pick this up and differentiate between the two? And show in my post swim data?
Thanks!
Please, I need help in a specific issue. The altitude in Fenix 5x is given based on barometer only or it gives you the altitude based on GPS also?
The elevation it tells you is a mix of barometric and GPS. For short term changes it’s mainly barometric, but it automatically re-calibrates off GPS on longer time scales.
I don’t know of any way to get it to tell you separate numbers for GPS and barometric.
This is a review of a million words, but did you really test the watch?
I bought it on Monday…and been suspicious about it’s accuracy since second one!
Yesterday I spent a full day outside in the cold:
14806 steps performed or 12.3km…
This helped to make 308 active calories…cannot be right, I am a 83kg man…
Hearth rate is always slow to catch up also in running mode;
Fitbit with products that cost a fifth is more consistent.
Also if I understand HR may be a work in progress, calories calculation is a simple calculation, cannot pass on this one, really bad.
This morning after one full hour of breakfast making and washing dishes, it accounted 3 active calories…like making a toilet break while sleeping.
If your calories are off significantly, it’s almost always because there’s a typo in your weight.
unfortunately there is no typo;
weight is correct;
age is correct;
height is correct;
I just updated my Garmin Virb basic and was playing around with it and my Fenix 5 Sapphire 47mm. Before it wouldn’t pair with camera for remote control but now it does. I just received an update for the camera and added it plus an update for the watch some time back. Apparently they have added this functionality. Just when I was going to get a new camera for this seasons snowboarding Garmin had to go an fix an issue. Well it saved me some money so now I can buy the a new helmet.

Just switched from Fenix 5 to Fenix 5X Sapphire, could you confirm that Vibration on 5X ist definitely weaker than on regular 5, or maybe I have a faulty modell?
It seems that the Fenix 3 can only store up to 30 courses on the devices (I cannot succeed in storing more courses, anf I have the latest current FW 8.50).
Is this limitation also on the Fenix 5 series, and more specially on the 5X ?
Thanks
link to support.garmin.com
Thanks Volker.
However my Fenix 3 has currently 30 fit files stored in the COURSES folder.
I don’t know if there are any differences between ‘courses’ and ‘routes’. On the device they are named “courses”; however in the link you provided they mention “routes”.
Anyhow, I cannot add more courses on the devices… the limitation seems to be 30 courses, and not 50 as described…
A bug ?
Hi Ray,
Thanks for the great review!
Do you know how to show the 25k topo maps from géoportail and swisstopo without buying them from Garmin?
Thank you for the review. However on one aspect you have put me on the wrong leg.
I do lifting and cross fit. I like to follow my HR especially when I do HIIT with weights. In these circumstances the HR doesn’t work at all. It’s not even close. The needle just doesn’t move. I can work my butt off but my HR will not raise above 100 which is definitely not the case.
You have any advice on that? I already regret that I bought the watch.

I picked up the Fenix 5x, primarily due to this detailed review (thanks!). I tested it out last night and was very pleased EXCEPT for the optical HR. I was doing hill sprints (8×30) and I live at 7,300 ft and the HR was waaay low (130bpm). I adjusted the watch to make sure I was below the wrist bone, tightened it, removed & put on other wrist, etc. But the HR was always low.
I really want to believe in the optical HR tech but I feel like out of the gate it’s wrong. Any thoughts? I really do not want to have to return the watch. It was cold last night (upper 30s) and my arms are obviously moving while doing hill sprints. Could this impact it?
If I go back to a traditional chest strap, what would you recommend for brands?
Any guidance would be greatly appreciated. Thanks!
I have not read all the post but in the review shall be added some test of Optical HR with HII Training or racquets sports…. seems that Fenix 5 is a poor performer.
That’s my opinion as well.
The HR measurement is a base for a lot of calculations an data. Calories, peak performance, VO2Max and training effect. If it doesn’t work properly it becomes basically useless for measurement of training progress.
The optical HR is rather poor to my opinion. I do regret I bought the watch!
Something else funny. I already had at least 3 times that the phone tells me to move while I am walking. The thing is clueless obviously. Or I am an angel hovering above the ground.
I haven’t seen any comments or advice from the rainmaker ass well…
Also clueless??
Typo: phone is watch (Garmin Fenix 5x sapphire )
*Posted on Vivoactive 3 Review also*
Ray – great review as always. Thanks for the CT discount for VIP membership!
Can you post some pics comparing the VA3 to the F5 series? I am really curious how it compares. I am on the fence between the VA3 and the F5 Sapphire (upgrading my Vivosmart HR+ and want to stop carrying my Garmin 1000 on trips just to record gym gym stationary bike rides with my HR monitor).
Thanks!!
Tim
First off…Ray, thanks for all your work and great reviews.
My Fenix 5X works well when at rest & for easy, short runs. But anything over ~45 mins, or at higher intensity and it seems to hit a ceiling and not register HR above 145. I’ve worn it with my Fenix 3 and chest strap (both watches set up with exact same profile), often seeing the F3 in the 170s but the F5 “stuck” at 145. This doesn’t always happen, at times the F5 will show higher HRs. But I can’t get close to recording a max HR with the F5.
I’ve tried wearing it as tight as possible, different positions on my wrist, and changing wrist (and adjusting the setting) but all with the same result. I only bought the F5 because I hate wearing a chest strap. If I could I would return the F5 and continue to use the F3. I can’t recommend this watch IF reliable HR measurements are important to you. It is a good watch 90% of the time, but it’s the 10% failure when I really need it that is frustrating.
I agree. 90% is not good enough if 10% does the damage. I have the same issues. I bought it to get rid of the chest strap. Paid good money for it and it just doesn’t work. I can get my HR above 100. It’s a joke.
Strange problem as you describe, I do not recognize this behaviour. During my runs I see regular values higher then 170. I compared teh values during a run with my old Suunto Ambit 2S watch with HR-strap versus the Garmin 5S. It’s not 100% exact but close enough. The average numbers were very close, the graphs were almost the same. Did you already google or contact the Garmin support ?
Amazon is letting me return it. I’ll buy the new HRM Run strap and continue to use my trusty Fenix 3.
If you can’t get it to register anything above 145BPM, then simply put – something is broke. As Fred noted, that’s not a problem I’ve seen elsewhere.
Really? Don’t you read other comments?
Here are some of the comments
—
By the way, today i was gardening, i think the OHR isn’t precise, i felt my HR was sky high when did some heavy works…the OHR diplayed only 94 hr…this wasn’t right.
—
I think for sports you wil always need to wear a cheststrap..
—
Finally, as for wrist OHR, in general it doesn’t work as reliably (across most devices), when you have tools/objects in your hand with a tight grip. Sorta of a reality there unfortunately with much of the sensor tech today (wrist-based).
—
I’d be surprised if the OHR could keep a reliable measurement though tennis motions.
—
I’ve been using the Fenix 5 for a couple of days now. Unfortunately, I cannot make the OHR sensor providing me with useful information. The HR reading is completly off the chart. I tried everything – I even shaved off the hair under the watch. It didn’t help.
Check out the picture attached. I did 10min uphill intervalls and the HR does not correlate with the effort at all.
—
I’m having some difficulties with the ORH. In addition to some of the expected issue flagged in Ray’s various reviews of Garmin OHR watches, such as difficulties tracking sharp intervals and some issues with road cycling, I’m finding random spikiness and unreasonably high readings in what should be less challenging situations. This morning I recorded my normal morning walk to work as an activity and uploaded to Strava. This was a downhill walk at a pretty constant pace. I have a pretty low RHR, and I believe that my HR during this walk is typically in the 70-90 range. The HR graph shows several sharp spikes, into the 120’s with gradual declines. There is no way my HR ever got that high and the shape of the graph is entirely implausible.
—
I do have to say that oHR just doesn’t work for me (haven’t had a single run without issues), while for many other people apparently it’s great.
—
I won’t be using wrist-based OHR because it is too unreliable for me,
—
I also had my first workout with the new device today, a 4×4 interval session on a treadmill. The heart rate was way off in the intervals. During the first two intervals it was off by 20-25 beats, and in the last two it was off with 10-15 beats. I tried to change the position of the watch during the workout, but the result was just as bad. During the resting periods it took the watch about 20-30 seconds before syncing with my HR again. I know intervals are tricky for OHR, but at some point during 4 minutes of hard intensity, it should be able to get it right!
Nope, you’re mixing up very different things.
HR inaccuracy is one thing – especially when it’s variable. But the person is saying that no matter what they do they can’t get the HR to show over 145, which is actually rather unusual.
Optical HR accuracy depends on many factors, a lot of them being how a person wears the device and uses it. But even then, sometimes there are issues – just like sometimes on chest straps there are issues. Anyone who says either is perfect is kidding themselves. Some companies are better than others, and anyone who lumps all optical HR sensors into the same bucket is also kidding themselves.
Like it or not, what I tend to see in real-life running/riding with people that use optical HR sensors is that most wear it wrong. Most wear it too lose (flopping around), and right atop the wrist bone (also bad). Certainly, some wear it right and get issues (as I even showed in this very post). But with 1,600 comments on just this post alone, I’ve long since given up on trying to reply to every optical HR sensor bad-moment with the list of how to try and troubleshoot it.
I have solved my HR issue with a Scosche OHR band around the lower arm. It’s working fine. It also proofs to my opinion that the OHR of the Fenix5 just sucks. I have worn the watch on exactly the same place (holding it nicely in place by an neoprene elbow support which I used to support my joints and ligaments during training). It still doesn’t give the results. It’s too slow as far as I can see it. I think the sample frequency icw perhaps the strength of the less is just not good enough.
Anyway I have serious doubts about the OHR of the Fenix5.
It depends obviously what sports you do and how fast your HR goes up and down. Both for cross fit and HIIT indoor rowing it just doesn’t work.
And is not a optical Hr problem, my polar M600was perfect in recording Hr during high intensity sessions. Running is ok but other sport can’t be recorded properly… GARMIN support is even not responding to my questions….
Agree. My polar A360 with optical HR works fine.
I found some more flaws this morning. It’s no recording sleep data. Not so imported but it just doesn’t pick it up although I have been wearing the watch during the night.
At Garmin they can’t care less.
Fenix 3 HR Sapphire is on sale for $400 CAD in BF. It is better value than the fenix 5/5x due to the price difference.
Wow, very detail
>>In any event, I suspect that either the 5 or the 5S will become my daily watch going forward (I tend to like smaller watches over the larger 5X). The Fenix 5 has quick responsiveness, accuracy, and is easy to use. Simple as that.
So did it??? Or did you go back to Apple watch?
Generally if on a Garmin watch, I use the FR935 these days.
Today, I wore no watch.
WHAAAT… No watch??
NOOOO…
You are missing out on steps ;-)
Fenix 5 wrist heart rate inaccuracy in Stand Up Paddling.
At the start of the session the device reads the correct heart rate but a couple of minutes into the session the heart rate reading drops and stays at a level of about 37% of max heart rate for the entire session, whereas it is in reality about 75% of max as measured by my 920 with chest strap.
I’ve tried tightening and loosening the wrist strap but it make no difference.
Any insight on this issue?
Sapphire glass or no sapphire glass? I am wondering if the cost upgrade for the 5S makes sense. I have a few knicks in the bezel of my old 235 and 220, but nothung overly noticeable. I am a data nerd, so am thinking the Fenix is best, but am very interested in protecting my investment. I’ve never put a screen cover on my phones and haven’t had any issues. I only keep my watch for a couple of years, have been lucky to be able to upgrade, I just don’t know if it’s with the cost. (Plus I like the black and silver best!) Plus I wear it every day, since I work at a running store.
I made the choice for none-sapphire glass and the black-silver version. It looks very nice even as a regular watch. However I put a screenprotector on the glass to avoid accidents happening. I’m also very carefull but my previous smartwatch had some scratches (on the screenprotector) due to unfortunate scratching a wall.
For me the price difference is too large (despite the additional band you get) and the black version looks the same as the FR935 (which is cheaper but has same functionality in plastic case).
I hope my two cents help you make a choice.
Hi Ray,
If the price difference between Fenix 5 and 3 HR is ~$100, could you suggest if F5 is worth it?
Thanks,
XS
My husband likes to hike and hunt. He has gotten lost a few times in the woods. Although he obviously finds his way back, I’d like to buy him a watch to make it a bit easier. I am guessing the Fenix 5X won’t help much, since he is always off the beaten path? Is there an app on any of the watches that can help him track where he starts walking and then lead him back there when he is done?
He also runs and works out every day so I’m sure he will appreciate any of the Garmins. Any recommendations for which one would be best suited for him wandering in the woods?
The whole 5 line has a navigation feature called “back to start” which would help. The 5x would have the additional advantage of a map for context where the 5 and 5s would just display the track.
In one of the recent beta firmware F5 updates (and subsequent up to software version v7.00 BETA) there was a BTE/ANT/SNS firmware update to v5.30. Does this update mitigate ANT+ reliability problems?
The BTE/ANT/SNS “Sensor Hub” update from v4.10 to v5.30 happened in F5 Software Version 6.83 BETA from November 23, 2017.
No change there. Sensor hub stuff is generally just very minor tweaks behind the scenes. I don’t expect to see any mitigation at this point to the ANT+ reliability issues.
In addition to this new sensor hub firmware, there are release notes on BETAs just prior to v6.00 RELEASE that indicate changes to ANT+ power management to improve reliability.
I reached out to Stryd support who indicated that they have made a modification to the Stryd firmware to increase the transmition power of their device and Garmin has made some tweaks on the Fenix 5. “I think those two factors have mitigated the issues that arose earlier.” The net result is that they are currently not getting complaints about dropouts from their F5 customers.
It makes sense to me that there could be a physical design problem with the F5 RF that causes intermittent problems at the margin that could be mitigated by things like boosting transmition power, scaling back aggressive power management, and possibly tweaks at the protocol level. While not fixing a physical problem they could make the marginal difference between flaky dropouts and reliable.
It seems like there is some reason to be cautiously optimistic.
Do you still have an F5 and Stryd that you could test with the latest?
Yup, I can give it a whirl on a run today.
(I stated what I stated above, because Garmin has been pretty consistent in talking to me in saying they didn’t see any way forward on this without hardware changes. On the flip side, Stryd did have a technical solution for the specific chipset Garmin was using they believe could have made a difference. Garmin was hesitant on that for reliability reasons. Perhaps this beta is them winning a bit of a test to see what happens.)
Hi,
Loved the review but unfortunately my Fenix 5 doesn’t record power consistently with my stages power meter. A work colleague has a similar issue and I have seen numerous forums discussing this issue. It seems Garmin are in denial. This is incredibly frustrating. I expect a 500GBP watch to work without a hitch and to be thoroughly tested by the manufacturer.
I had a look through some of the other comments but have you experienced any issues?
Stages have given me a brand new unit which I will test this week but I am not optimistic. If it still doesn’t work I will be sending it back and moving to a rival product.
Thanks
Neil
This is the never ending blame game between Garmin and Stages here. Ultimately, there’s basically two ways to look at this:
A) No other power meters show this issue on Garmin devices, except Stages.
B) Most other head units don’t see this issue, except Garmin with Stages.
On item B, one should probably remember that when it comes to power meter GPS watches, Garmin outsells everyone else like 95:1 for GPS watches, so it’s harder to see those trends.
None of which really changes your predicament. Try pairing it on Bluetooth Smart instead, some folks have seen better luck there. While there are issues as noted in the review on connectivity to 3rd party sensors on the 5/5S, Stages is one that’s kinda been an issue for years across many devices. It’s generally agreed upon within the industry that the transmission coming off of a Stages power meter is less than most other power meters.
This generally fails for people on the wrist specifically because usually people using it are on tri bikes, and usually that means their hands are further forward, and usually against aerobars. Which usually means you’re body acts as a huge signal blocker (wrist), plus the aerobars and related cockpit goodness.
Not making excuses for either company, just explaining the reality of the situation that’s been this way for years.
I disagree with the statement ‘no other power meter show this issue with Garmin’. My ‘G3 Powertap hub’ drops in and out of my Fenix 5 too. I am not on a tri bike, I am on my road bike (size 56 so not overly large frame with a long reach).
I compare data with my 510 and it is sometimes way off. I never had this issue with my Fenix 3. So what I can say is the Fenix 5’s reception is pretty ‘crap’ in relation to the Fenix 3. It is disheartening and frustrating as I prefer the size of the Fenix 5, the straps are better (although, I could put one on the Fenix 3). I like the split between anearobic and aerobic during an activity and I like the 24hr heartrate (although, when I do a ‘proper activity’, I will use a HR strap as I know the HR in the watch is not reliable when doing intervals etc.. I expected that from the go)..
Anyway, first world problems.. Now the issue is, do I sell the Fenix 3 or the Fenix 5? Do’oh..
Continuing the dropout theme I get dropouts using the Garmin Tempe sensor.
All I here is:
Change the battery. Done it.
Reboot the Fenix 5. Done it.
Keep the two devices closer together. Tried it.
I wait untill the Tempe connects before starting the activity. During the activity it periodically drops connection and records data from the built in thermometer causing spikes in the graph.
I fall into your catagory of geek full of data and find this issue frustrating.
Has anyone had or even cured this issue.
Cheers.
Phil.
I get the same annoying issue with my 935. I’m pretty sure it’s a firmware bug and I’ve already contacted Garmin about it a while ago. Another annoying issue is that I have two Tempes and sometimes find that the watch will connect to the sensor that’s on my running shoe circa 30ft away through two brick walls, but not the bike’s sensor that’s just 1-2ft away. It would be great if I could prioritise a sensor for a particular activity, i.e., just look for the running Tempe when starting a run, and just the bike one when starting a ride. In terms of ‘curing’ it I’ve found if you go into sensor settings and force the connection to the appropriate Tempe I get no dropouts, however I’ve only done this three times so far as it’s such a palaver to do at the beginning of an activity, so it might just be a coincidence. Ray any chance you mention these issues to Garmin please?
DC Rainmaker, thank you once again for a great review.
Some folks mentioned they wanted to see more on the navigation features, and I have a step-by-step there (and more of a hiking based review) on my site here:
link to hikingguy.com
I purchased a Fenix5 as a one stop device – however adding to the dropout issues: For me, a Watteam Powerbeat and Stages. Both of which work flawlessly on other headunits, including other Garmins.
Interesting is the fact that BT is more stable than ANT but not 100% – and ANT is supposed to be Garmin’s own protocol!
Garmin support actually responded that they dont support 3rd party devices, and are more or less burying their head in the sand over it – despite marketing the device to support all of these features.
It’s more than BT coming off Stages is at a slightly higher signal strength.
The challenge is that the Stages unit signal is well known to be an issue (and has been for years). Combined with the lower quality reception on the 5/5S, it hurts.
Yes, I have connection issues Fenix 5 with Stage powermeter. And connection Garmin Edge 510 to Stage no problem. When I put Fenix 5 on frame of bike very near the pedals, than ok, if I put on the wrist and make distance between pedals and watches bigger, then connection failed. So I can use F5 on home , close to turbotrainers and pedals, because want estimate my VO max by Fenix 5, but after it will be not possible in the spring , when will start outdoor season. So it is all very sad, because I did`t find this issue before buying F5.
Hey folks, I just recently switched from the 735xt to the fenix 5. So there is one thing that drives me nuts: All my activities that I recorded with the 735xt had “Elev Corrections” enabled. For the fenix 5 they are always disabled and the discrepancy between the altimeter & corrected data is huge. Now, I don’t know which data is more acurate, but I want to compare my new activities to my old ones. So why can’t define the “Elev Corrections” for my fenix 5 to be “activateed” for all (future) uploads? I automatically deactivates the correction for new activities! So, Is there a work around? Thank you in advance!
Because altimeter is better.

I am not able to locate the Leather band for the Fenix 5X on the Garmin website. Do you know how to order one?

Hi ,
I have a fenix 5s with the normal glass screen.
This week, it broke after a very small impact that i even haven’t noticed.
Is the expensive repair (± 182 €) by garmin the only solution for this problem?
Or do you know another solution for me?
I have a Fenix 5 inbound for my birthday (not sapphire). Does anyone recommend a screen protector? Do you really need it? I bought it from REI so it has a 1-year satisfaction guaranteed clause in case I wish I had the 5X or the 5 Sapphire.
I am mainly planning to use it as my primary activity & sleep tracker and to keep track of workouts, walking and hiking while traveling (2-weeks a month). I may start swimming this Spring as well.
Hi
On my fenix 5s do I use a screenprotector since about 5 weeks (24/7). It withstood hiking, training and a little swimming and showers. Better safe then being sorry. I bought mine on Amazon link to amazon.co.uk
They are a little smaller but this is helpfull in applying them or getting them off if needed.
Up untill now, no scratches.
Hallo Dear Rainmaker,
please, can the Fenix 5x show HRV on display all the time, while running.
You answer would make me glad. Thank you
No.
The 5X’s optical sensor can’t do HRV during a workout (nor does it display raw HRV data natively). Perhaps there’s some 3rd party Connect IQ app that does something I’m not aware of for day to day use.
Hi Ray! Do you have any idea as to when Garmin will release a new watch to update the Fenix 5? I have taken so long to buy it, I don’t want to invest in it to see another model come out right after! Thanks in advance and happy holidays!
Hi Ray,
Apologies if this has been asked before, i just cant read through all of the above questions…sorry.
Is it possible to add an existing set of GPS coordinates (given to me by someone else) to my Fenix 5x? If so, how?
Thanks for the great review!! It helped me to decide between the Fenix and the Spartan.
Just received my F5 and started using it (I’ve been using a FR620 just to run and ride, so I will have to consider wearing a watch all day again).
Keep the great work and our lives easier everytime we need to decide where to jump next on our devices!!
Thanks Garmin – a christmas present I’ve wanted for ages.
on the latest beta we have: Added the ability to access ‘Broadcast Heart Rate’ from the Controls menu (Settings > Controls) as well as through the system Hot keys (Settings > System > Hot Keys).
no longer 42 key presses to connect HR to Garmin edge
This is my first comment. Over the last decade or so I’ve been relying on DC Rainmaker’s in-depth reviews to influence my purchasing decisions. Thank you!
Now how about the Tanita BC-1000? It has ANT+ but I can’t find anything about 5x compatibility.
Thanks DC Rainmaker for this resource!!
Cheers
Garmin stopped making watches that work with ANT+ scales some years ago (3-4 I think). However, I believe Tania does have a Connect IQ app that works with it (and on the Fenix 5), but I don’t know the details of how well it works.
I Just got the 5s and so far I love it but there’s one niggling little thing I can’t seem to change.
I like to use my watch to track the various gym classes that I take. Obviously when I am indoors I do not care about distance, speed, or GPS. However I cannot see any option in the default Indoor Cycling Activity to shut off GPS and stop reporting speed and distance. (I’m not going anywhere on a stationary bike).
I also created a custom activity called Class for a bodypump style class. I was able to get the watch to turn off GPS, and to only display the data I care about (calories, time, HR). But in both instances when I stop the activity it still gives me a distance displayed. Is there any way to cut that out?
I’m just really surprised that in many of the factory-provided indoor Activity types, that it’s got GPS on by default with no way to configure it to stay off by default during that activity. I don’t want to have to go into system settings and toggle GPS every time I start an indoor workout!
it’s also annoying when i go into the mobile app to see my activities summary for the day and I see “Indoor Bike : — mph —- speed 55:00 minutes” – ideally i’d love to just see time/calories/hr. Distance and speed are irrelevant (and unmeasurable) in indoor spinning!
I’m really curious about this as well! I currently have a VivoActive HR and want to get something new as they don’t make these anymore. During my gym workouts with the VA HR my watch displays Work out time and Calories burned. If there is a way to set this up on a Fenix I am sold. If not I don’t know ill stick with Garmin :(
It‘s on sale at the moment @amazon.de for 359,20 €
Price is 449 but black/grey has a 20% off coupon which is activated during checkout. Sold by amazon directly.
Thank you a lot for that tip!!
But one question: Is there a successor comming in the next month?! .. A Fenix 6? What are the rumors for that? What new features is it going to have?
Garmin bot?
I am not impressed with Turn by Turn on my Fenix 5X on trails and nature preserves. Do I have to get the 24K to get turn by turn and to help me discover and navigate trails and nature preserves? How can I explore these trails and find them then load on my watch so that I don’t get lost while on them? Any ideas on a website that helps with this or would the Garmin 24K topo maps and basecamp help with this. I now that many trails in Michigan are not found on the 100K topo. Thanks.
I have a fenix 3 hr. Turn by turn navigation works by picking up map metadata rather than recognising a sudden change in direction. I found this to only to work in urban environments and not on trails (at least not in the UK). You can build a route in Garmin connect and download to the device. It does not seem to support waypoints (the website now sports a clunky way of adding these after much criticism but it doesn’t work). You can use other route creation tools such as Strava (free) and copy the gpx download to the hidden newfiles directory but it ignores waypoints. Suunto does the whole navigation thing so much better (see my previous comments). The idea of maps on a watch is a gimmick. You just need a route displayed to indicate the direction you need to travel at the appropriate level of zoom. Look at a paper map now and then – hi res – enormous screen – colour – visible in direct sunlight – infinite battery life. Its safer and its fun! Garmin is only interested in marketing. Their strategy is to produce lots of device variants with lots of features to penetrate as much of the market as possible irrespective of whether they work properly or even at all. I use my Polar M430 for serious training and my old Ambit 3 for hiking at which it excels.
P.S. and both devices cost less in total than a fenix 5!
I’m hard on a device so I’d need the Sapphire edition of any. So that is a game changer for price it appears.
I have the non sapphire Fenix 3 which my dog now uses, strapped to her collar, for walks and canicross. She’s about as rough as you could get on a watch but it hasn’t scratched yet and never missed a beat.
Ok, so I googled ‘how to attach Fenix 5 to dog collar’ and this is the only thing that came up 😂 how did you do it??
I’m not the one that made the comment, but I’ve been strapping my 5X to my dog’s collar to see how far she goes when we go on off leash walks in a park full of other off lease dogs vs how far I go (usually 1.8x’ish, for anyone curious). I’ve been using hook and loop straps. Seems to work pretty well.
I have these collars link to amazon.co.uk and I unscrew the watch band pins and run it through like a normal watch band or for Fenix 6 onwards because they changed the pins (for the worst) I bought a little pouch that they sell on places like Etsy that are attached to the collar and usually used for a tracker but the watch fits perfectly. Both my girls have the 5 and as ML said great for seeing how far they go so most days I’ll do 10k and the Dalmatian will do 11/12 and the GSP about 14/15 but she once did 22k when we walked with another Pointer and we did 8k.
Thank you for the very useful review.
Do you have investigated about the Bluetooth range of Fenix 5? I’ve observed that its range is shorter with respect to the forerunner 235 and to polar m400. I’m referring to smart notifications between the phone and the smartwatch. In particular it loses the signal when the phone and the smartwatch are in different rooms, at a distance of 4-5 m, while the other watches are still connected. Have you observed the same behaviour ?
Thanks
Really appreciate your exhaustive product reviews, very helpful, well done. Question on Garmin Connect privacy.
Just got a Fenix 5 and bike sensors to replace my (don’t laugh) Polar 625SX. Initially loved the Fenix but now am totally spooked about privacy since the thing needs to be linked into Garmin Connect which looks like a Google data mining play once one looks under the hood.
Fenix is a beautiful multipurpose device I can use for training, competition and wear to work without looking like a dork BUT looks like everything I do from bike to bedroom is getting synced 24/7 to Garmin and then shared. Some digging and I find Garmin Connect code pings Facebook (graph.facebook.com) and Ad Trackers (tags.tiqcdn.com) even though I don’t use Facebook and I set Garmin Connect to private, private. So now Facebook and who knows who else has my phone IP and associated it with my device (if you have a phone IP you have a name). And Garmin Connect privacy statement references using personal data for marketing purposes and sharing with affiliates, etc.
Using free services like Gmail means Google will pretty much record and sell everything you do, that’s the deal. But after paying $800 for some Garmin gear last thing I want is all my activity mined and monetized via Garmin Connect. Remember when Lenovo got busted for embedding Superfish in laptops? Or when Samsung TVs had open mikes? That’s kind of how I feel now.
Any idea how much of our data Garmin is monetizing and any way we can stop it? Or alternatively if there is a desktop only option for the Fenix (similar to my old Polar with the desktop app) where all of our data isn’t sent to Garmin? I don’t use social media, zero interest in sharing, comparing, etc. just want my metrics. Any thoughts or insight would be appreciated.
Garmin Connect privacy policy.
link to connect.garmin.com
IANAL: They appear to claim not to share your data with 3rd parties unless you connect to other services like Strava or use social media login. They do use Google Analytics and Azure analytics on the servers and HockeyApp crash analytics in the Garmin Connect app.
So they say but then why are they providing Facebook with my phone and watch IP even though I have set Garmin Connect to private? Also, privacy policy references service not for use by those under 16 so if the personal data is 100% locked down, why the disclaimer for children? Unless you opt out, Garmin most certainly shares your data and I believe even when opting out they still share (like my phone and watch IP address).
I’m not a conspiracy theorist but I am in the IT business so anything connected to the cloud basically is in play. Good summary here on privacy concerns with activity tracking devices – link to techcrunch.com
Hi and happy new year to all,
I’ve recently bought Fenix 5x after few happy years with ambit 3. I was amazed by how bad the web interface is. Specifically, I could not found any way to change watch specification (eg light on or off during workout). Does anyone knows how to set watch specification at the web interface and then sync it with the watch?
Cheers,
Itamar
Lacking an F5 myself, I’ll go out on a limp and say that you probably should look on settings on the watch itself, all garmin devices I own can alter each setting on the device itself. Doing this by a web interface is taking a detour and may not work at all.
Great review as ever… now to buy the 5X!!
dear rainmaker
thanks to your review I bought the fenix 5s. i used to have a tom tom . dont get me wrong it did his job but now i can cleary see why this watch costs more. im super happy with it.
and besides the white color is beautiful
Simple answer to this most likely. How do I get to the music control widget while using the watch for a run? When I try to scroll up and down I just get the different run screens. Thanks in advance anyone!
1. You need to have installed the music controls widget.
2. To access the widget loop during a run, you need to HOLD the down button (assuming you still have the default hot key setup).
So far so good with my fenix 5 after a week. A few minor drop outs on with the tempe sensor, but Vector 2 Power Meter pedals seemed to work ok after a few rides and Scosche HR worked fine for my Sunday 4 hour ride.
Clarity of the lcd screen is noticeably better then the fenix 3, that certainly helps with my failing eye sight. It’s also the perfect size for my wrist. I eventually got used to the fenix 3 size, but this is better.
I’m also digging the stress metrics and increased HR data capture. Expensive as all get out, but I found one dirt cheap on ebay.
hi , is anybody having issues with Altimeter ? I have a fenix 5 and altimeter is completely off, looks like i have been on everest few times! i called garmin support here where I live and they are very aware of the problem … they proposed to replace it, but they are not sure i will not encounter this issue again, to the point that they said i could consider going for the FR935…
I had the same problem, altitude ranging from +65,000 feet to – 1,200 in the same spot on my brand new $750 Fenix 5 Saphire. I believe problem to be more likely related to barometric based altitude adjustment rather than GPS because these wild swings occurred during crazy weather here in DC; however, my issue was resolved by (1) removing all non factory watch faces and (2) calibrating altitude and barometer with GPS. Keep in mind if you have watch on ‘auto’ your altitude will be driven by barometer so big weather system comes flaming in and your elevation will swing accordingly.
I didn’t run a strict testing protocol but I am certain watch faces played a role because (1) when installed I experienced lag or non reponsiveness on some buttons/functions and other weirdness and (2) all problems disappeared when I removed the watchfaces (I know, post hoc ergo propter hoc but too much of a coincidence. Also try comparing your watch barometric reading with local weather station – pick an activity, add barometric pressure as a data screen, and then you can compare to weather station. Might not be exact because some stations may altitude adjust but should be in the neighborhood. Hope this helps.
I think it is a lot easier to find negative feedback on the Itnernet than the silent majority that are reasonably happy.
I have had a fēnix 5 saphire since May and I have had very few problems. The firmware updates have generally resolved issues that I have had and introduced new features.
I had one GPS track go haywire during a cross country race with GPS+GLONASS enabled and a clear sky with no obstructions. On that occasion the only other runner with GLONASS enabled (on a fēnix 3) also got insane results. I subsequently turned off GLONASS and never had another significant issue. I subsequently learned that GPS+GLONASS is probably best for use in a city with tall buildings to improve tracking where there are a lot of reflections and interference with the sky. It generally makes it worse with unobstructed sky.
I had the display freeze and become unresponsive during a fartlek session while running a beta firmware once several months ago and I thought I was going to lose data. It turned out to be entirely a display freeze and after about 5 minutes the watch recovered and I had data and a GPS track for the entire run that looked sensible.
The GPS tracks and mileage is reasonably accurate and comparable to TomTom, Fenix 3, Forerunner 25,Forerunner 35, Forerunner 235, and Forerunner 620 results that my buddies get. The 1km pace and splits are always reasonable (with the above one-time exception). The instantaneous pace is sometimes very wrong but will correct itself in a few seconds. I feel like there has been some improvement in this area probably using the accelerometer to smooth the pace. I’m located in Southern Africa with very few tall buildings.
Back around June or July on one occasion, I had course navigation telling me to turn into the wrong road maybe 100m too early. There have been several firmware revisions and that issue did not recur.
I find the wrist heart rate sensor to provide reasonable-looking results 99.9% of the time. Rarely, I will see a spike that seems questionable but I also have seen occasional wonky results on a chest strap. Overall, it is a win for convenience.
The barometric sensor seems to give reasonable results except when I did an entirely uphill mountain half marathon into a rain storm where the barometric pressure was falling due to weather while I was also climbing. In this case it read quite low compared to adjusted GPS net elevation gain in Garmin and Strava.
The temperature sensor on the watch is clearly affected by body heat and I don’t think it consistently provides accurate numbers within 5C.
I have fallen in a cross country race and tumbled and bounced the watch face off of a rock which left no marks. I also fell once on a steep muddy descent in the rain head and arms first into mud and rocks. My skin was torn up, there were scratches on the rubber strap, but once I washed the mud out of the watch there were no marks. I don’t think my old Forerunner 230 would have survived either of those events intact.
I easily get a full week between charges with doing activity tracking workouts daily, mostly outside with GPS enabled.
I don’t currently have any ANT+ or bluetooth accessories, so I cannot say whether I would have an issue with reliability of personal area network devices.
Also for comparison, I have some mates with TomTom watches and in the past year two of those have done either complete scribble GPS during a race or shifted the whole track by at least 100m diagonally so that it doesn’t line up with any roads. None of this tech is perfect.
I would be happier if the display were 30-50% more pixel dense but not at the expense of significant battery life.
Overall, although it is expensive and not perfect, I have been happy with the device. Enough so that I just purchased a fēnix 5s for my wife.
thanks Dc Dan for your suggestions , I will try !
Does the garmin fenix 5 have any gps-problems?
I’ve got one since mid November and have don plenty of runs and bike-rides. When compared to the Forerunner 735xt and my note 5 the accuracy of the fenix 5 is notecibly better! I’d say it’s the best performing gps-device that i’ve ever had.
I use GPS+Glonass and I did several test-tracks, i.e. zick-zack runs, “Writing-Runs” (trajectory represents letters & words), etc. The fenix’s performance is stunning and I could clearly “run words” within a 5m*5m-letter-raster.
So did I miss something?! What problems is the fenix 5 said to supper from?
Also: Since it’s CES now, what are the rumors for a fenix 5 (plus/titanium) update and/ or a fenix 6 models? What is expected to be new and when is it speculated to be released?
Thank you all!
So you’re the one that got the functioning Fenix 5! But seriously, I love my new watch but GPS is all over the place and seems to be a common complaint based on the Garmin forums; however, being a new user I’m withholding judgement until I am certain I am using the darn thing properly. As per my previous post I have found conflicts with supplemental watch faces so have removed them all and now the watch seems to be running fine. Still a few quirks but these could be intentional, still learning the thing.
Aleander, I was attempting to reply to your comment and seem to have replied to the person with a barometric pressure sensor problem accidentally. See my comment to you in #1675.
Best.
As a scientist I know that no measurement is flawless – quantum theory tells us that. At a classical physical scale we do not always have the luxury of constancy in conditions other than the one under investigation and yet conclusions can still be inferred based on statistical analysis. A good example is the measuring of strains on a suspension bridge by applying a known perturbating force with a known period – the short term much larger effect of traffic is virtually eliminated as it is relatively random and the sampling period is long. The chance of a significantly smaller spread of values detected by feller for some devices is so highly unlikely to occur by chance we should discount this. Of course all the GPS watches are OK – depends on your needs. Trail running in the UK may require great precision to avoid missing a track and in my experience Garmin watches aren’t really up to this whereas Suunto and Polar are. Unreliable instantaneous pace may be an important issue for some. Getting rid of the longer GPS antenna for marketing reasons has an impact on performance which may or may not be important to an individual. Let’s not pretend there is none.
Neither fellrunr nor DC Rainmaker are able to test fo sample variability by having several of the same units. Anecdotally it does seem like there is significant sample variation, particularly in early production units. There have also been a lot of software updates and it isn’t clear to me if ConnectIQ apps and data fields can affect the overall performance of the device. (I suspect they can.)
Your UK trails must be much more difficult to navigate than the trails in the bush in Southern Africa. I know many people navigating ultra run trails in the bush using Garmin Fenix and TomTom Spark. The Fenix 3 is the most popular watch with the F5 trickling in. I only know one person with an Ambit3 and her watch died on the 21km group run I was on today. (I’m sure she just forgot to charge it.)
My real world experience is that all of the recent watches are pretty similar in performance most of the time. Sometimes any one of them may freak out without an obvious explanation.
In any case I think the testing that Ray has done tends to show the devices are all pretty acceptable in real world GPS performance.
“…it isn’t clear to me if ConnectIQ apps and data fields can affect the overall performance of the device. (I suspect they can.)”
They certainly can. A few months ago I put a ConnectIQ field (I think, I don’t remember what it was any more, could have been a widget) on my Edge 1000. From then until I finally realized what was happening and removed it, I had ANT+ connectivity problems which I had never had before. That Garmin permits an IQ thing to screw up a core purpose of a device is worrying.
It is a shame a third party site such as Strava is not able to provide this information. It has the luxury of a huge population sample of real world use and it knows which devices were used (though I don’t believe the sampling or recording rates). Segments would provide an ideal basis for comparison. I bet some companies would pay to keep this quiet! (if they have not already done so).
My only African experience is of running in the Sahel in W.Africa. If the bush in S.Africa compares then yes, running trails in the UK is far more demanding for a GPS device (though not as physically challenging for the athlete!) for obvious reasons (Very sparse vegetation compared to to lush nigh on temperate rainforest in S.Wales and a large number of very narrow trails).
Not sure why you mention someone not charging their watch – what is the significance?
My real world experience is that the world is flat, projectiles run out of impetus, particles do not exhibit wave like behaviour, simultaneity is not relative and moving clocks run at the same rate as stationary ones.
It is a good job some brighter sparks were able to see beyond the “real world” or we would not have atomic clocks, special and general relativity and …. oh yes, GPS which is based on these non real world concepts!
Ha! Yes, West Africa is very different. Terrain ranges from veldt, to vlei (wetland), to mountain and dense forest.
The real world I inhabit is actually an oblate spheroid. That means I have to deal with time zones and my international airplane flights travel in arcs. Quantum effects happen in my computers all the time and a practical application of Einstein Relativity allows instantaneous, cheap, and fairly precise geolocation.
I don’t see much practical evidence that any male or model of consumer GPS watch is dramatically more or less accurate than 3-4m for each measurement and ~3% overall. They are differentiated by other features and industrial design and branding. I’ve seen faults happen on different makes and models that were not repeatable.
Garmin’s breadcrumb navigation does, in fact, work fine.
Hello Ray
First of all, thank you for your great reviews.
I have a simple question for you:
Garmin D2 Charlie is the same that Garmin Fenix 5x, but including aviation mode?
Thank you
interesting!
link to fccid.io
could a fix to the ANT+ issues finally be on the horizon?
So what this practically means for existing unhappy users of fenix 5 sapphire
(unhappy because of stryd incompatibility and generally dropout issues because of poor signal)?
I’m hoping it’s going to lead to the ‘silent fix’ that Ray suggested and that we’ll be able to swap our watches out for one’s that work
My Stryd kind of works with mine but my Tacx trainer is a compete nightmare :(
I hope that that is possible scenario.
This is the most in depth product review I have ever read. Period.
Hoping to train for my first Ultra with a 5s soon!
Kudos and thanks.
incredible , after having had fenix3 changed 3 times as they all died, now with the 5 the barometer altitude issue.
i really want to like this watch , but they just don’t work. I have to say i never ever returned a suunto or a polar , never .
I think it’s just poor manufacturing. Great customer service though they are always ready to assist and give you a new watch, as i am sure they know they always have issues.
maybe spend a bit less in customer service and more in quality of manufacturing could make sense.
It seems like there might be some progress with the F5 antenna issues:
link to the5krunner.com
Dont know if this will mean a product recall, or a newer F5 variant… Hopefully we will see some announcements in the next few weeks…
Too much is being read into that FCC spec item. Far too much.
The issue around connectivity has *never* been the antenna with the Fenix 5. It’s the specific communications chipset they selected on the 5/5S, they can’t get the power out of it they need for the range they want. By time they realized the extent of the problem, the ship had sailed. Antenna placement can change for a million reasons, most notably shifts in other internal components.
I’ve argued they should have paused sailing and addressed then, but alas, I’m not the captain of that ship.
It does say it is to increase power output of ANT+ and BLE though so a bit puzzled if it’s not to address the problems
at the end, the fact is that fenix 5 have serious flaws when is paired with different sensors (p1 pedals, stryd…). for example I have big difference of NP between 520 and fenix…
Generally speaking, when people have different NP values, it’s because they’ve set zero averaging to be different.
Dropouts can be a cause, sure, but only two people above have reported P1 issues, which is pretty minimal.
I cant work out if it is Garmin or Huawei who are to blame for the current bluetooth incompatibility with the fenix 5. Each one are blaming the other. Anyone got any inside info on the current situation.
I do swimming, cycling and running and I’m a bit confused with Garmin’s product line-up. For me, would there be any difference between a Fenix and 920XT ? Both seem good for swimming and running workouts (I use an Edge 520 on the bikes)
Is there any reason to buy a Fenix over a 920X, or vise-versa ?
The 920XT is a generation old. It’s a solid device but kinda clunky looking and doesn’t have an optical wrist HR sensor. There’s nothing wrong with it. Solid and reliable, lots of people I know use them for Triathlon up to Iron Man and Ultra running. You should be able to get a good price.
The FR935 replaces the 920. It has a round display and newer software. It supports the latest accessories and comes with optical HR sensor, but you will want a chest strap for swimming and cycling. It’s a Fenix 5 in a plastic case without the metal bezel and sapphire crystal option. The FR920 seems to have marginally better Bluetooth/ANT+ connectivity than the Fenix 5 and 5s (but not the 5x), which makes a big difference for reliably connecting to the accessories from 3rd party vendors that should be compatible. YMMV.
The Fenix 3 HR is very similar to the F5 but in a larger case. Main difference is the software is a little slower and the screen resolution is a little lower and less colorful. The F3 series does not support the latest ConnectIQ API for 3rd party apps. The Fenix 3 non-HR is more similar in functionality to the 920XT, but heavier andlooks a lot cooler. You can get the F3HR new at the same price as a F3 on Amazon, so I would not consider the F3 without the optical HR unless you are getting a steep discount.
*Edit…. Just realised the 920XT has been superseded by the 735XT / 935.
I have found that my Stages PM is now holding a connection with Fenix 5. Not sure if a firmware update addressed this but I’m happy none the less.
What firmware are you on? I’ve been on a bit of a roll trying various Garmin devices. Just finished a 35km ride with my (new to me) fenix 5 Sapphire and I had zero drop outs.
Units used during the ride:
Forerunner 935, edge 810, edge 1000 and fenix 5 Sapphire (with firmware 7.60). All units with 1 second recording and Glonass off.
Paired to the devices were:
Tempe
Vector (2) dual sided power
Scoshe optical HR
When I compared all 4 activities in Garmin Connect, every single activity showed no drop outs in sensors (ok, 2 small drop outs from the tempe with the 935, but zero drop outs otherwise).
Ray, your thoughts on if Garmin may have solved some issue here with ANT+ connectivity? I was going to sell off the fenix 5, but now might move the 935 along.
Here’s the fenix 5 file:
7.60. I have had over 100 miles with no drop outs. Worn on my wrist and mounted on Madone handle bar.
One week in on 7.60 and no drop outs either (vector 2, Tempe, Scoshe optical HR)
When I figure out how to link my activity’s here I’ll do so.
Hi, what’s your view on the altimeter / barometer problem of Fenix 5? My device is absolutely crazy on that and this unit is already the third trial (thru RMA)?
Hi there. I was wondering if there are different versions of Fenix 5x Hardware out there. I mean, i wouldnt like to end up buying some really old version of Fenix 5x (first ones out there) which may have hardware issues.
I know software will be probable needs to be updated which is not a problem cause that works like a charm, but is there anything i need to know about hardware?
Thanks a lot in advance!
Hi DC
Thnx for this review
Do you have any idea why the HR monitor is “all over the place” after the firmware update on December?
A lot of people are facing similar issues. Heard anything? Any tips maybe?
Its really disappointing . I came back to garmin with top of the line watch after a 3 years pause with suunto cause I didnt like their software issues and they fail on basics.
Ikeep up the good work,
John
I’ve noticed my HR isn’t accurate any more now. I’m on the latest FW as of now (7.60).
Yesterday was a cold duathlon event, 3.6m run, 17m bike, 3.6m run.
The ride was 2 laps. My pace and effort was pretty much identical. 11 seconds time gap between each lap. Conditions remained the same.
Temp was 6 degrees with a cold north wind.
My HR on the run looks normal. My HR on the 2nd run takes about half a mile to “come up” and is then normal.
See attached pic for my bike HR. It just stops being accurate about half way through the cycle. This isn’t the 1st time i’ve noticed this.
The watch is tight on my wrist, not moving during the ride or the runs.
Any advice, is the unit faulty? It’s < 1 year old, purchased from Wiggle. Should I look for an exchange with Garmin / Wiggle?
Thanks
Dan
Dan,
One of the body’s responses to cold conditions is to divert blood flow away from the limbs and the surface of the skin, and restrict it to just the head and core (preserving body heat for the essential organs). As OHR measures changes in the light reflected back from the LEDs with each heart beat, reduced blood flow makes getting an accurate OHR reading from the watch harder.
The legs are probably OK, because they are working hard and generating heat, but blood flow to the arms would definitely be reduced in the conditions you describe. The additional wind chill from the higher speeds during the bike leg would make the body colder, but core temperatures may rise slowly when running again, which would account for the timing of the HR accuracy.
A chest strap is probably going to be a better option in those conditions.
Great info.Never thought of it this way
Though I am running in Greece with 15 degrees at a February night I’ll keep in mind the blood flow factor and the temperatures.
Thank you Andrew.
Since posting my own research has backed up your reply. You’ve described it perfectly.
Cheers
Dan
My initial watch used to be perfectly fine, but some weeks ago the Barometric altimeter started to go crazy showing constant changes in altitude. I got a replacement unit. It had worked properly for 4 days and then the same problem occured: the altimeter is all over the place on my peplacement device. Its going up and down from +20000m to -20000 within several hours.
Is this problem known? is there a fix? Recalibrated everything several times. Same problem on sw-version 7.60 & 8.00. After reinitialization same problem. I wouldn’t want to get a 3. replacement..
Since I have a lot oc custimization (activity-profiles and Data-field setups): Is there a possibility to transfer all the settings (i.e. activity-settings) on a new watch? Where is that settings file located?
Thank you for your help!
I have the 3rd unit now and it has worked for two days now ?. I have no trust on this though. I have been following discussions on the topic and I am extremely disappointed that Garmin keeps radio silence. That is a shame. I would have hoped a statement from DC too, but maybe I have missed it.
Aleander, I had the same problem, altitude running from +65,000 feet to –1,200 in the same location. Try this – remove any non factory watch faces and compare your barometric reading to a local weather node to check your sensor (add Barometric Pressure as a data screen to an activity to make it easy to view) . In my case the third party watch faces were hosing things up. Removed them, did a reset, recalibrated, and now all’s fine. Also the Garmin logic in Auto mode tries to figure out if the barometric change is due to you changing altitude or the weather. This can be tricky on a long hill climb which can mimic a slow drop in baromometric pressure.
Just looked at the thread a bit, but hard to discern what’s going on as it’s been over the course of 8 months or so.
I’d start with eliminating 3rd party apps first, and then go from there.
As a general rule of thumb with any device from any company, I find that if someone goes through 3+ units in rapid succession, it’s almost always something specific to that person’s situation (environmental, settings, usage, etc…). Not blaming, just saying that’s the best place to start and kinda walk back troubleshooting from there. Certainly, there are the rare units with manufacturing defects (or the general 5/5S communication stack issue), but beyond that there hasn’t been much in the way of widespread issues.
Thanks. If you take a while and look at the issue for instance in Garmin’s own discussion forum, you might notice that this may be epidemic. I live in North-Finland and it is cold and dry, but I would expect the device to cope with that. Others have similar experiences in other conditions, I have noticed. My previous unit went crazy at the 1st training session in the woods. I was once for a decade at the company within the same business and know something about the devices, but I wouldn’t like to go back to those as I find Garmins much more lucrative from spex point of view. And from their outlook. I have had long discussions with Garmin Finland and their service is great, but either they do not have a clue what the problem might be or they cannot admit that because it is that epidemic. I hope my present unit stands with my cross country skiing and MTM in these rare extreme conditions.
i am on my second fenix 5 , and have exactly the same problem again. I am currently at 8915 mt of altitude according to the watch.
Garmin at least here in Switzerland is very aware of the problem , they suggested replacement or to switch to 935… it looks like an issue with the metal case… this watch is of no use for people like me that use it especially for mountaineering activities
Altimeter Problems in 3 fenix 5 devices.
I purchased a fenix 5 sapphire in mid-January, 2018.
I repeatedly hit the problems of the altimeter being inaccurate by orders of magnitude: 65000+ feet and 32000+ feet elevation readings…and the down to negative 12000 feet (in areas of about 200 – 4000 feet above sea level)
I already returned 2 fenix 5 devices that had this problem and will be returning the third one I currently have.
I have the latest firmware, have done re-calibrations, multiple resets and do not have additional watch faces and apps loaded.
I am very familiar and experienced with devices that use barometric pressure for altitude. I have never seen problems like this with other Garmin devices with barometric pressure based altitude on such as Garmin Edge cycling computers and the Garmin Montana handheld GPS units. Same with 10+ year old Suunto watches. I’m using the fenix 5 in same areas / use cases as the others devices.
Garmin support did not acknowledge any specific known or widespread problems with the fenix 5 altimeters and offered to replace the device yet again, but after 3 strikes I’m done. It would be great if we could get some type of statement on where they are on the root cause analysis of this problem. It is not an isolated instance given that some people who care about altitude functionality are reporting it in various forums (including Garmin’s) and are also seeing it in replacement units…and there are likely others who do not take the time to post.
Since altitude is one of the most important measurements and metrics for my activities, I will be returning this for good as I’ve lost confidence in the device and Garmin’s ability to solve this problem for this device.
I’m disappointed because I’m otherwise very satisfied with the overall functionality and form of the fenix 5.
Hi
My story is indeed similar and there are others. Besides that I’m disappointed with the product quality I am extremely sad with Garmin’s and its ambassadors’ silence. Anyone can see that this is epidemic, at least. I am not an engineer but have worked in a company making HRMs in North Finland and I know something about if the problem is in HW or in SW. I would be happy with a statement that we are working with the problem and you will get a solution as soon as it is fixed. Now we have to keep replacing units and listening before it to how the device has to be calibrated etc.
KJ
I had two Fenix 5’s with the same altitude issue. Switched back to 5x and it doesn’t accurately track my skiing speeds or HR. Skiing speeds ranging from 80-125mph on various firmware versions.
My 2nd replacement Garmin Fenix 5 replacement with a bad pressure sensor. Both this one and the previous one quickly glitched. I do think static electricity is zapping the capacitance based pressure sensor causing it to go to a reading of 0 millibars over time. This one has been on my wrist for 3 days only. Temp is —-, barometer and altimeter are —-. Watch altimeter climb today for hours to over 65k feet and then it stopped working.
And when you contact Garmin, they will either replace it without questions or, for the sake of formality and before the replacement, they give you the link to the calibrating instructions. Fair and reasonable.
Kari – I agree and feel Garmin has done and will do the right thing with respect to replacement. I would like to know what actual conditions are causing the pressure sensor to act the way it does. I have determined that the sensor is drifting (ie: it is still sensing pressure but for instance mine reads 589.1 mb (should be about 1015 or 1030 mb) so it has drifted a lot. If I increase pressure it responds (ie: increases) and the altimeter will drop or the barometer will increase. The problem is the ambient is jumping around much more than normal. Wearing a long sleeve shirt or removing a jacket (causes static electricity discharge) causes it to retreat from it’s real reading and creates what I call a new bias point that is much lower in mb. The watch tries to compensate by either increasing altitude or lowering barometer reading (depends on setting of watch and logic).
This is an issue with the circuitry and logic of the pressure sensor – it appears gradually change the values even though the sensor reading is pretty sensitive. It reaches a new bias and if one calibrates with that incorrect bias, stability of measurement is ruined.
Just while typing this with the watch on my arm it is down to 582.7 mb. A bad storm is 6 mb drop within an hour ….
Living in Baltimore MD, the temperature outside is 55 degrees and the humidity is normal today. Even though most heated buildings are dry, the Fenix 5 pressure sensor should be able to withstand typical static discharge, but that is not the case with the 3 I have had. The first one was the least glitchy, this one is the most. Comparing serial #s, the first one was manufactured in April 2017, these in November 2017. They are over 90000 units apart in serial numbers, so I know that there has not been a change in hardware or manufacturing process with respect to the barometer.
This may be a 3rd party problem – I am sure Garmin sources these from a manufacturer like Infineon – it is most likely the problem either with the sensor itself or the integration of the sensor into the device (ie: mechanical casing, electrical connections, power supply, data lines, logic, software drivers, etc.)
Problem seems to have hit the 5, 5S, 5X and 935 as well as the 3HR all with varying degrees. 5 seems hardest hit.
My Fitbit worn on the opposite arm still counts steps.
I bought mine in December so I have a lot of time to see if Garmin figures this out. I love the watch otherwise (if I was not injured I would be out running, but since I cannot run I am doing stairs every day).
Thanks Mark :-) Your analysis would indeed explain the issue. What I am still awaiting is Garmin’s statement, explanation or instructions on how to go around this. Coming from a similar background, I cannot understand or accept the radio silence.
Hello,
That is a great review and info.
I’ve had an unfortunate experience with Garmin using a Fenix2 and have not considered their products since.
That watch would crash through a ride or a run. Switching from sport to sport in Multi mode, crashed. If it ran out of space, it’d crash and was very difficult to connect to PC and free up space.
I went back n forth with Garmin while still under warranty and they were very reluctant at the time to help much or send me a new unit. Eventually they sent a refurbished unit only after they’d received the problematic unit.
Unfortunately the same started happening with the old unit at which point I just gave up and decided not to look at Garmin again from a product standpoint and a customer service standpoint. It worked for 3 months prior, barely worked thereafter and won’t even hold a charge now. I’ve not touched it since last Spring 2017. Junk.
So, having read this eval, I was wondering if anyone here had expressed similar issues with a Fenix 5 as I’m reluctant to fork out another $600+ (I’m in Canada) on a problem product and then deal with not-so-helpful support from Garmin
Thanks

Hi Ray ,first thanks for your work I read your blog since many years.
I don’t understand though the environmental, usage , settings remark, I have had many ABC GPS watches and never had an issue with altimeter barometer .. I sent my second fenix 5 for RMA and currently using an old ambit vertical which has perfect altitude readings .
Apart for that I really like the watch , but for me altitude datas are very important .
Regards
It seems that this is not a “widespread issue” officially :-D
Environmental means the following:
A) Specific to a person and how they use/treat the gear
B) Specific to the region they’re using it in (such as weather that might include humidity/dry air/salty air/etc…)
C) Specific to what the person might be wearing (such as specific pieces of clothing that have a higher likelihood of transferring meaningful static electricity)
D) Some other random factor that’s unique to a given person’s day to day situation that causes and issue
By and large, most non-software tech bugs of all products after the first month or two tend to fall into environmental type issues. Meaning, they’re harder to solve because it’s a unique thing to that person/environment that can’t be easily repro’d elsewhere.
I’d specifically note the static electricity one as a very likely cause of breaking of altimeters. Certain clothing is far more likely to cause issues than other. For example, I know I’ve got one running tech shirt that for whatever reason always zaps me. Why? I don’t know. Some clothing expert could probably tell me…but I don’t know why that green shirt always does that.
The reason we know it’s not widespread is the numbers just don’t support that. By now it’s a safe estimate that Garmin has probably shipped between 750,000 and 1,250,000 Fenix 5 units. Roughly (based on historical trending of Fenix 3 units and such while getting more popular). If this was a huge issue that had hundreds or thousands of unique comments on those threads, then I’d be more concerned.
Instead, it’s still a totally sucky thing for those that run into it – but that means it’s not likely to be considered a widespread issue that everyone runs into. Obviously it sucks being on the wrong side of it, especially when it’s hard to figure out what causes it. But if a given person goes through 2-4 Fenix 5 units in a short timespan with the same issue, then that almost exclusively points to something unique about that person or their environment.
Ray, far from trying to have a discussion with you on sport tech, you a guru and know well what you talking about , but i am not convinced on this one.
i had many many gps ABC watches in the past 15 years, and never ever had such an issue where i would go from 15k mt to -32k.
the reason why i think many people don’t complain about the altimeter out of the hundred of thousands who own a fenix 5, it’s probably because they do not use this specific function . I live in Switzerland and I use the altimeter of course :-) …
the fact that Garmin itself on a phone call suggested to probably look at the 935 instead after a couple of RMA, to me looks quite obvious that they are aware of the issue.
I have zero technical knowledge but I do have many years of usage and again never one of my previous polar suunto or garmin itself gave me such a problem.
Still I like the watch and I hope the 3rd one will not have the same issue.
regards
Ray, your answer is fair, thanks. However, I cannot yet believe that this is not a bigger problem than you suggest. I have been using various Polar devices, and devices of another Finland based company because of some coop between those at some point of time in history and I never faced this. Further, if you design a device like Fenix 5, you simply have to take into account such environmental factors as you list. Fenix 5 is a device that should stand quite a lot in terms of environment and there are engineers who can reach that. I cannot make a hard claim but to my current understanding, Fenix 5 has design failure.
Curious if these altitude problems are occurring in GPS or UltraTrac OR offline when watch is in Auto mode and it’s extrapolating altitude via pressure changes (which can be waaaay off)? Also not clear if these problem watches have checked sensor accuracy with known values like local weather nodes and topo maps. Apologies if this was already covered or maybe I’m completely missing something.
My assessment as a first time Garmin customer and Fenix 5 owner is that the altitude problem, at least on my watch, seems to be the logic for differentiating whether pressure change is due to weather or altitude when watch is in auto mode. My barometer readings match the local weather node and calibrating altitude via GPS matches topo maps so sensors seem accurate.
I’m going by the Garmin book for offline (no sat link) use – calibrating altitude via GPS and leaving watch on Auto mode. Problem is that watch makes assumptions about pressure changes – slow and its weather, fast and you must be moving. Generally this has held true for me provided I calibrate every day and keep moving (or I stay still and the barometer is steady). If I don’t calibrate for a few days my home/starting point altitude starts to drift up or down 50’ – 100’ which isn’t unreasonable given the crazy weather that comes through Wash DC. And overnight I can go +/- 50′ – 100′ while asleep so that’s obviously weather.
When I first got my watch I too was getting +65,000 to -1,500 altitude swings. Removed non factory watch faces (I was getting button lag or no response on some functions), did a hard reset, recalibrated altitude and barometer via GPS and been fine ever since – when I calibrate at home I get the same altitude every time and high and low points on rides, runs, and drives are the same as well. But mix in some weather and long slow hill climbs I’ll get variations. Haven’t tried GPS or UltraTrack yet so maybe that’s where everyone is having trouble but so far all of my GPS calibrations have very closely matched topographical maps in the DC metro area.
But if folks are using GPS or UltraTrac and getting +/- 65,000′ variations AND their sensors consistently correspond to known values (weather nodes and topo maps) then I’d agree something going on. Just not on my watch except when I had the wonky watch faces.
I think A) might be the cause for my problems. Here is my experience:
Bought a fenix 5 last November. Everything awesome. After one month however, the fenix 5 froze, i.e. hung up during a long, cold trail. But it could reboot after 20min and continued recording. Same thing happened twice some weeks later during runs in very cold weather. And finally in mid January again the watch hung up while running but this time it never rebooted. I did not know better and simply tried the soft-reboot pattern and/or connecting to pc.. So I got a replacement. It had been working just some days and suddenly both the altitude- & barometer-drifting began followed by a temperature reading of “—“. Soon after the drifting began the watch hung up and was not rebooting, just like the previous watch. So I replaced it another time and the story repeated itself after a week with the 3. watch.
Now, however, I’m happy with that 3. watch, as I can confirm that a hardreset will make the watch work again and all the sensor readings will be perfectly fine. I searched for different button-press combinations on the watch to do a hard-reset and was able to enter the Test mode, which showed everything is fine with the watch’s hardware. Now it’s been working perfectly fine for a week.
Conclusion: The one constant thing on all the problematic watches has been a custom watchface. I’m not sure if the watchface really is the cause for the problem, but now I use the native face and had no issues so far. So if you happen to get the same sensor driftings/errors, do a backup before and try a hard reset. Hopefully it will work again. And get rid of the custom watchfaces.
Another thing: I think the garmin support is very good. they replace the units quickly by new ones. So no complaints from my side.
I have been trying to comment further, but obviously I am thown out. At least I cannot see my recent comments.
The device shows you 2 kind of air pressures:
1) Ambient Pressure (AP) which is the “true” figure and which can only be seen in training modes
2) Barometric Pressure (BP) which can be seen in widgets and which is based on AP and calculated further based on weather etc.
In my faulty devices, AP was all the time between — and a high figure such as 10 0000. I live at sea level and it should be always ca. 980 – 1050.
If the AP is e.g. 20, the device assumes you are in the “moon” and you get a crazy high figure. If the AP is 100000, it assumes you are at the sea bottom. The figure of AP is the one to blame in this comedy.
If you in such a crazy situation calibrate your altitude with GPS, you get the right altitude, but just for a very short moment. The device starts “correcting” the figure immediately and you are soon again in the space or on the sea bottom.
Why the AP give crazy figures, I do not know. I hope it would be sw related, but I am afraid it is not. I think the engineers have simply ignored standard design steps what comes to testing static electrics tolerance. Now we have to avoid skiing in winter, wearing jumpers and keep washing the device in soap water every now and then.
I would not dare to use their diving instruments before a fair explanation.
Kari – For some odd reason one of your comments got stuck in the trash bin which appeared to have a ripple-on effect for your duplicate variant attempts. Not really sure why, as there’s nothing in it that’s SPAM/Trash worthy. Odd. Anyway, found it and fished it out. Sorry about that.
As the two previous commentators noted, I’d be curious if you have any custom watch faces or apps – and if so, if you’ve tried their steps. I totally get singular bad units, or even singular bad batches (or heck, even a few weeks of bad batches). But generally speaking when the same individual goes through three watches (especially from the RMA pool, which is the most random way possible of getting new watches), it almost always falls back to an issue that’s somehow unique to that individual.
Not trying to place blame that it should be your problem to untangle – but rather, just trying to help troubleshoot.
Hi again – I think one my faulty devices had an extra face, but at least the last one didn’t. It went crazy almost immediately. I have been thinking of what I do wrong or what circumstances may cause this, but the only thing I could say is the weather. It is dry and cold here. In winter and with the last faulty device, I did only xc skiing. Garmin asked me to test it for a while before the replacement – they wanted to have the file as well – and in those sessions I had my Edge 810 in the pocket and it gave right recordings. While the Fenix was at Garmin, I used my beta M400 and it gave right recordings. Also, I had the M400 on my wrist 24/7 those days exactly as I had my Fenix and M400 didn’t take schocks from anywhere. The AP / the respective sensor is the reason, but is it in the SW, HW or in some combination, I do not know.
I have always got new devices as replacement
Do you have any added ConnectIQ things on it at all, not just watch faces? Try taking them all off.
I observed ambient pressure (direct pressure read by sensor) jumping around. The sensor appears to skew its’ baseline (generally dropping) when exposed to static electricity. I believe the sensor is capacitance-based. The ambient pressure should somewhat match current barometric pressure compensated by altitude. The actual barometric pressure – altitude compensated (maybe with some temperature compensation.
For me at a few hundred feet above sea level that number is usually a little over 1000 mb when the sensor is working correctly. Right now my ambient pressure is around 950mb but is fluctuating up and down (while inside a building). I get no measurement of climbing or going down 8 stories of stairs.
When it works correctly I could do stair climbing sessions and see the 6 flights and 6 descents done twice on the elevation chart of the activity. I don’t get any flights anymore with this Fenix 5 (3rd one).
This is definitely a widespread issue with the sensor (maybe bias gets messed up due to static discharge) or I am unlucky (3 for 3). Ruled out 3rd party apps this time.
I tried warm water with mild detergent as Garmin mentioned. Helped but can’t get the sensor to ‘settle down’
There is an ambient pressure connect iq widget that shows the true story of what is going on.
I have also had my last couple attempts to post not take (tons of typing)… Echos exactly what Karl and others are stating about ambient pressure sensor …. this is after soaking the watch for an hour and it sitting on the shelf all night. Ambient finally is recovering.
I have attempted multiple posts but they don’t seem to have made it here …. saw with with another person as well.
Yesterday I did a hard reset of my Fenix 5. I also did a 30 minute warm water with mild detergent (per Garmin’s web site FAQ) soak. I paired with my phone, but have not added back any connect iq watch faces, widgets, data fields or apps. I let the watch sit overnight off of my wrist. This morning I placed the watch on and went about my daily routine (actually at a hospital where my daughter is ….). The altimeter and barometer are working within reason all day with no large retreats. I am not looking at ambient pressure, but looking at barometric pressure it is reading in the 1010+/- range and the altitude is maybe 150 feet off (I have not calibrated it) but responding exactly as the watch should. I climb 8 flights of steps and I see the altimeter respond fairly quickly and accurately. I go back down steps and see roughly the original value shown. I drove home tonight and the elevation change roughly was pretty decent (no random ascents or descents) and the altitude at my house was maybe 160 feet off. I did calibrate the altitude (leaving the watch in default auto-mode) and all seems ok. We do have a low pressure system over us and the barometer is about 999 mb, weather channel states 1000.3mb. Right now the sensor is pretty darn accurate.
I don’t doubt the sensor is affected by static discharge, but maybe some connect iq widgets and/or watch faces are causing the sensor hub not to properly handle recovery from a glitch?
Are some of the Watch faces you download from GC throwing off these watches? In my case, I think it was really draining the battery, although I don’t know why. The watch face was pretty simple but had a steps counter and 1 or 2 other things.
Here is a probably slightly offtopic question, but still, I hope you can help:
I recently bought a PowerTap C1-Powermeter and I use it with my fenix 5. Everything works flawelessly and I already did several FTP tests. So I aim to train in powerzones and I’d like to show a smoothed %FTP- field in the fenix’s screen.
All I can find, however, is an instantaneous FTP-field, which jumps around like crazy all the time, rendering this datafield totally useless. So is there a way to show the 3s/5s/10s %FTP-average like it is possible to be done for the absolute Power?
Thank you in advance.
Yeah, throw me on the list of people with huge altimeter problems. Been going on since I got the unit, and I’ve gone back and forth on email, but based on what I’ve read on Garmins forums, they’re not acknowledging the problem. Today, I’ve been on quite the roller coaster ride today with this watch. With the exception of its inability to connect to my stages power meter, it’s been phenomenal, but the altitude issues are abysmal. Yes, it’s cold where I am right now. Yes, I wore a synthetic shirt skiing all day today. Yes, it probably generated static. But that’s what I bought the watch for. Skiing, and hiking, and biking and running. And I live in upstate NY, so it’s often cold. Shouldn’t the device function during these activities? My fenix 3 never experienced this issue under the same conditions.
I’m on that list too. My first Fenix 5 went awry within a month. Warranty, got another, that one went wacky after a couple weeks. Now they are sending me a 5x, which they say doesn’t have the same issues.
Last week I went skiing… At the base of the mountain I was at 60k ft elevation, by lunch time I was at an amazing -520,000 ft.
Wow my best is 93,000 above sea level. Interesting that they gave you a 5X–did you ask for it or did they volunteer. I just soak mine every couple days–pathetic.
