Hands-on: Suunto’s new Spartan Sport Wrist HR Baro

Suunto-Spartan-Sport-Wrist-HR-Baro

Certain countries are known to have residents with exceedingly long names – in some cases 5-6 words/parts long.  Finland however, is not typically one of those countries.  But it appears that Suunto is aiming to grab that title in any way they can with their just-announced Suunto Spartan Sport Wrist HR Baro.  In this case HR happens to abbreviate ‘Heart Rate’, while Baro is short for barometer.

This watch builds upon the existing Suunto Spartan Sport Wrist HR unit that I reviewed this past spring.  The Suunto Spartan series is, of course, Suunto’s lineup of watches that introduced last year as a successor to the Ambit series.  While it got off to a rocky start, things are definitely finding their stride – especially with the incredibly well priced Spartan Trainer that recently came out.

With today’s new watch though, Suunto is aiming to take the Spartan Sport series and add in a barometer for it to display more accurate elevation data, as well as maintain the wrist-based optical HR.  This effectively aims to fill the gap on a mountain/hiking focused device that also does optical HR.

In any event – I’ve been using the unit now a few weeks and it’s time to get right into things.

What’s New and Different:

DSC_2039 DSC_2040

In many ways, you could sum up this entire post with: ‘They added a barometric altimeter to the Suunto Spartan Sport Wrist HR’, and be done with it.  And, that’s probably true.  But since I have an ample supply of Starbucks Double-Shot energy drink can thingies tonight, I’m going to push on with more details.

See, there are a number of minor tweaks and differences that are worthwhile noting (compared to the basic Sport Wrist HR), many of them trickle-down effects.  So here goes:

– Gets Barometric altimeter data (duh)
– Gets FusedAlti (combined GPS and baro altitude for more precise elevation data)
– Gets altitude in daily mode (watch-face)
– Gets automatic altimeter/baro profile
– Gets storm alarm
– Battery life remains the same
– All this for a mere 1g addition to the total weight

So while yes, there is the addition of the altimeter, the impact of that is greater from a software standpoint.  Obviously, virtually everything you see above is aimed at the mountain seeker, or someone doing a lot of work with ascending/descending.

DSC_2633

All of that previously required the ‘Ultra’ edition, which is not only higher priced, but also carries with it a bigger battery (significantly bigger).

DSC_2744

(Left to right: Spartan Ultra, Spartan Sport Wrist HR, Spartan Sport Wrist HR Baro)

Of course, the Ultra edition doesn’t have an optical HR sensor, but the battery differences are massive.  Here’s the lineup for the GPS modes (Best, Good, OK).  Each of these modes changes the GPS refresh rate and now includes much higher battery savings (using a firmware update coming October 17th) – up to 140hrs on the Ultra now!

Note that they don’t change the heart rate or cadence recording rates, which are always updated at 1-second intervals:

Suunto Spartan Ultra: 18hrs/35hrs/140hrs
Suunto Spartan Sport: 10hrs/25hrs/80hrs
Suunto Spartan Sport Wrist HR: 10hrs/20hrs/40hrs
Suunto Spartan Sport Wrist HR Baro: 10hrs/20hrs/40hrs
Suunto Spartan Sport Trainer Wrist HR: 10hrs/16hrs/30hrs

So as you can see, the battery life hit of the Baro is nil, though it will set ya back an additional $50 over the base Sport Wrist HR edition.  Speaking of which, here’s how the lineup currently sits:

Suunto Spartan Ultra: $699+
Suunto Spartan Sport: $399
Suunto Spartan Sport Wrist HR: $499
Suunto Spartan Sport Wrist HR Baro: $549
Suunto Spartan Sport Trainer Wrist HR: $279

One of the things to keep in mind here is that Suunto’s GPS-based elevation does tend to be exceedingly good, so much so that the use cases for a barometric altimeter for many people tends to be slimmer than back in the old days when GPS altimeter data was rougher (or on other competitors devices where it’s rougher or entirely useless altogether…lookin’ at you, FR735XT).

As such, I wouldn’t necessarily shy away from the cheaper Sport Trainer Wrist HR, in fact – it continues to be my favorite out of the entire lineup of Suunto Spartan units.  Partially for the size, partially for the price, and partially for the accuracy I see.  Which, is a great time to segue into the next section.

Finally – for lack of anywhere else to stick it, the Spartan units that have a barometric altimeter will get a new ski mode that displays the length of runs, number/counter of runs, vertical descent, and maximum speed during the descent. All that comes within the October 17th firmware update.

Early Accuracy Testing:

DSC_2875

In having the watch the last few weeks I’ve been getting in sporadic workouts with it.  Given that last week was Interbike, and this week is the ANT+ Symposium, my workouts are kinda wonky and all over the place – literally.  I’ve got runs and rides with it in Paris, Amsterdam, Las Vegas, and Reno.  And now I’m up in Canada.

Further, note that while the hardware is final, the software is considered beta.  So likely we’ll see some tweaks between now and October 17th when it starts shipping.

Thus first, let’s start with the HR sensor. In the case of this watch, that’s pretty darn unlikely since the exact optical HR sensor package from Valencell hasn’t changed, nor has the exterior of the unit.

But what I’ve come to see is that accuracy of optical HR in the Suunto lineup seems to vary between the larger Suunto Sport series and the smaller Suunto Trainer.  To summarize this entire upcoming section: The smaller (and cheaper) Trainer series seems to have much better accuracy than the Sport series, despite having identical sensor packages.

Why?

Well, size.

The larger the watch, the more it bounces on the wrist while running – no matter how tight you make it.  With the Suunto Spartan Sport/Ultra series being larger, heavier, and more top-heavy, this exaggerates the problem compared with the small and lightweight Trainer variants (or compared to the less top-heavy Garmin Fenix5/FR935 options).

To demonstrate this a bit, here are a few runs.  The first in Paris where it struggled at the beginning to track HR (despite standing around and waiting for satellite lock):

image

And again it did the same in Reno during those initial few minutes, followed by cadence-lock spikes later during the harder intervals:

image

Yet there were cases where it seemed to nail it, like this run in Amsterdam which showed very consistent HR accuracy:

image

Next, let’s look at the GPS accuracy.  I’m not sure what’s going on here, and neither is Suunto.  But they’re taking a look at it.  In short, during running workouts, it seems to struggle, while cycling seems fine.  Even in cases when the cycling terrain is FAR more difficult than the running terrain.  For example, this run last night with it in Reno, whereby there’s nothing above me.

2017-09-24 18.05.24

///UPDATE: Suunto believes they have found the issue in my GPS data, which is related to GLONASS:

“The GLONASS option is intended to be used in big cities where high buildings both block the sky and generate signal reflections from walls. GLONASS brings more visible satellites on the sky and the SirfStarV chip has an offset correction algorithm used together with GLONASS for correcting for reflections from buildings. It has however turned out in our tests that this correction algorithm actually takes you off track when running on normal trails. That’s why our generic recommendation has been NOT to use GLONASS unless you really are running between buildings.”

I haven’t seen this recommendation previously by any company, though it does roughly match what you’ll see throughout the rest of my post with my data.  Note, that I’ve left the rest of the post as-is with the data seen.///

It’s out on the flats with virtually no trees at all, just simple bike paths around a pond to the right there (that loop):

image

You can see it’s all over the place.

image

The same with Amsterdam – where it would seem to offset the location randomly throughout the park.  It’s the teal line you see crossing water:

image

Yet mountain biking up in the mountains with snow-covered trees and mountains on the side and it had a solid track for the out and back route:

image

So not sure what to say on that one.  All runs were with GLONASS enabled, and ‘Best’ GPS accuracy.  Again, Suunto is digging into these as of this morning (since that’s when I got around to loading them all into the DCR Analyzer).

So what about barometric altimeter accuracy?

Well obviously, that’s why you bought this unit.  As you would expect you can either specify a reference altitude or you can use GPS to do this for you:

DSC_2895

I generally would use GPS for the initial altitude, for the very simple reason that I generally don’t run/ride/hike in places that always have altimeter markings sitting around at the start.  Certainly, when available it’s great to cross-reference that.  But in my case, none of my workouts had those available.

To start I’ve got the interesting use case of Amsterdam and being technically under sea level.  The watch placed me at –96ft, which is significantly more than the –2m that’s generally agreed upon for the inner core of Amsterdam.  Plus, the ‘lowest’ part of the entire Netherlands is only –7m.  So that’s wrong.  But on the bright side, it was almost identical for my start and end points.

image

Plus, I learned something interesting with the above: The DCR Analyzer rejects negative elevation values, hence why I can’t show you an overlay chart between the units.  Need to get that tweaked!  It looks like perhaps the Suunto unit is just as misled about being under sea level as my tools.

Here’s a road ride I did in Boulder City, NV that had some elevation change to it.  What’s interesting here is that the initial value altitude offset you see (~40m) between the Edge 1030 and the Spartan/Vivoactive 3.  Those two units after settling out in the first few minutes stayed locked on each other for the remainder of the ride.  The gap/difference between the units while similar did shift a bit with the gap widening on the Edge 1030 very slightly.

image

Now again – there was no altitude marker to know for sure which one is right or wrong 100%.  However, if I look at USGS elevation data, the starting point of my ride is listed at 801.8m.  The Suunto was at 800.2m, and the Vivoactive 3 at 795.6 and the Edge 1030 at 839.8.  Seems clear enough to me Suunto nailed this data set.

image

Btw, as a funny little test of how sensitive the barometer is – check out this chart below.  You can see we descended down initially, and then there’s a huge flat section there in the chart.  That’s where we spent 2 hours filming stuff for upcoming posts.  In this case, the Edge 520 sat on my bike mostly off to the side static, while I wore the Suunto unit on my wrist while I moved around.  I was constantly going back and forth in a small section, up and down a hill controlling camera gear.  It’s neat though to see how sensitive it is to pick up this 2-8m elevation gain as I did this.  Obviously, the Edge didn’t shift much because the bike was static.

image

This above chart has no valid comparison aspect for the center portion, but I just thought it was kinda neat geekery.

In any case – I’ll be holding out final opinions on all accuracy angles until we get closer to release – but for the barometric part that’s new here, it does seem to be on the ball.

Wrap-up:

DSC_2905

This watch is essentially two things for Suunto.  The first is a way to appease those folks looking at the Spartan Ultra series for a barometric altimeter while also wanting optical HR.  While the second is offering Suunto a slightly more wallet friendly option to consumers than the Garmin Fenix 5 series, any of which costs more than the new Spartan Sport Baro variant would.  It’s priced similarly to the FR935 ($50 more actually), which also has a barometric altimeter.  Though those two watches are distinctly different in sizing and form/fashion.

The Suunto definitely has more swank factor in the design than the plastic FR935.  While inversely, some might prefer the much lighter and slimmer FR935 (almost half the weight of the Spartan Sport editions).  All of which ignores any feature or accuracy comparisons.

And a better time to make those comparisons may be down the road once they start shipping on October 17th.  Suunto has noted that more features/updates are on the way to the Spartan line-up.  Some of those will be continued catch-up features, while others will be newer innovations.  Having seen the list, I think they’re on the right path here.  And of course, hopefully they can solve whatever GPS accuracy issues I’m seeing.  I’m less confident of the optical HR issues, as those seem to roughly mirror what I saw on the Sport unit this past spring (and of course, they’re basically the same unit).

With that – thanks for reading!

    What does the Spartan Ultra do that the new model doesn’t do? Is it just a question of battery life?

    Am I the only one that doesn’t understand which Suunto clock to buy? The last Suunto product I bought was a Garmin Fenix5…

  2. Rem

    Having an Ultra, GPS accuracy is worse with GLONASS enabled. So guess you would get better GPS result w/o GLONASS (Suunto need to re-work this one out ..

    • Angga

      I believe Garmin Fenix 3 have the same issue. It will screw my watch accuracy if i turn it on even if i run on the track with nothing but clear blue sky.

    • Markus G

      It probably has. I have owned and partly still own those Garmins: 920XT, 630, Fenix 5 and 935. With all of them I came to the same result: Glonass makes things worse for me. (I’m a trail-runner, usually no urban environments). I have only anecdotal evidence for that behavior of course.

      My main watch is a Spartan Ultra and well, it’s a known fact that the Spartan series has issues with Glonass. It’s the first thing you get told if you ask for GPS accuracy: turn off Glonass

      I know he’s seen a bit controversial but you also might take a look a Fellrnr’s GPS reviews (I don’t want to put a link here, I don’t know if Ray likes that).

    • Yeah, this is the first time I’ve had any issues with GLONASS enabled on any of my workouts anywhere in the world (even on other Suunto units).

  3. Julien

    Nice watch. Do you know if we can setup stryd for power, pace and distance?

  4. Pekka

    Can you tell use anything about battery life with 24/7 hr enabled?

  5. Nadine

    Hey, I for one am over the moon about this addition to the Spartan lineup. Have been running with the Ambit Vertical and love the altimeter data – but miss the optical HR. If you are spending lots of time in the mountains then the barometric altimeter is invaluable.

  6. KYLE

    The missing feature that Suunto will not address and even Ray doesn’t bring up is the Route Calculation. Suunto calculates by “as the crow flies” instead of by the route you have imported. Makes zero sense and a huge omission for a watch that is made for navigation. Garmin does it correctly and is the reason why I switched to the Fenix 5 from Ambit series. Zero reason why there isnt an option to have route based or straight line based calculation.

    • Rem

      Oct-17 Update will bring exactly that , “by the route”.
      ” Advanced navigation features brought by the software update include route navigation improvements with estimated time of arrival (ETA) and remaining distance to destination. ”

      Look at : link to suunto.com

    • Kyle

      I hope so but I believe that just means they are importing features from the Ambit series still. Ambit series has had remaining distance to destination for years, but as I’ve said before its almost useless unless you are going in a straight line. Ray might have some insight on the situation.

    • Brad

      The Ambit never had distance based on the route, it was always a straight line distance! I know I have one and used it and this is a major upgrade. The distance will be route-based not straight line or as the crow flies.

  7. Jaka

    Sexy new watch face … I hope they add some more to the Ultra as well. That storm alarm feature looks sweet too and not to mention reading about ski run data got me all wet … where’s my towel.
    Lovely design on this unit, I like it very much, although I would much rather see a nice smooth bezel like on the Ultra. The color scheme is bang on tho.

    Let’s just hope they fix the nasty GPS bugs that seem to be returning with every other FW update on the Ultra too.

    BTW, are they thinking about adding a “hybrid” sensor option to the pairing screen – I’m thinking about power, cadence from the same sensor and such things.

  8. Al

    Do you know what the October updates will bring to the Trainer line? Since it looks like you are testing out the Trainer, the Sport Baro, and VA3, which do you think has the more accurate HR and GPS? I had the VA3 for a week and just didn’t like the GPS on it, with and without glonass on running and walking in the city. It would show me like half a block off and take sometimes 3 minutes to grab GPS(tried two different units), and first time took 30 minutes to grab signal in a residential area. All I want is a watch for hiking, walking, stair climbing(nice bonus to have) and my daily activities.

  9. TheRunningDaddy

    I don’t get all the data comming from Suunto. Example: the last screenshot that shows altitude. Why there are so many small peaks? The same comes to heart rate data graph. All in all average heart rate taken from Valencell is almost identical as from Polar V800 + H7 strap (my tests), but both graphs of heart rate and altitude are more smooth in case of Polar.

    • As for the small peaks, as noted in the text it was because I left one unit static while I was going back and forth moving around filming stuff on the side of a hill. So it was actually capturing it. That’s what that whole geek-section was about.

    • TheRunningDaddy

      My mistake Ray.

      I ment movescount graph (black background with yellow graph) screenshot. Right after -21 indicator you have dozens of small peaks. I have those too on heart rate graphs on my SSSWHR and IMO this has something to do with Suunto algorythms.

      Thanks for the reply
      Cheers

  10. Timo

    And again: no GPS bump? The HR Trainer had it and -as stated here- quite amazing GPS performance.
    If so: could this be the cause of the inaccurate GPS behavior without the possibility to solve it later by software update? Is it only related to Glonass?

    BTW: I am still very satisfied with my Ambit3 Peak (Sapphire), doing multi-day high-alpine mountaineering with climbing. Hope that there will be an update to the Spartan Ultra, that I can rely on.

    • Jaka

      On the Spartan Ultra I’ve had very good GPS tracks to very poor ones where the signal is jumping around a lot. Some FW updates actually made it worse on my unit and some were flawless. It’s hit and miss, but I don’t give it too much thought, as long as I can navigate the hiking route to about 20 m accuracy I’m all set.

  11. andrew

    A simple question? This or Fenix 5? For gps and fc accuracy and for battery life. Thanks

  12. Currently using the Fenix 5x but curious about the Suunto due to smaller size and similar options. Does it support bluetooth connectivity where you get notifications from your phone on the watch?

  13. Panagiotis Zavrakidis

    And I just bought spartan sport whr 2 weeks ago. Bummer !

  14. Matt

    If I’m interested in sleep/activity tracking, lifting weights, running and perhaps biking in the future should I go with the Fenix 5/FR 935 or with this watch? I like the look and displays of this watch more, not to mention touchscreen is pretty cool. Although I have always liked getting metrics like cadence, etc. and the Vo2 and recovery data has been beneficial for me (I am currently using the fenix 2 and in need of an upgrade). I had a Suunto in the past, but was not very happy with it. In Suunto’s defense it was one of the earlier adventure watches they made without sport features and that was about 5 years ago (not really sure, could be wrong on that but it was at least 4 years ago i think they came out with the ambit shortly after).

    My question is basically, does this watch perform as well as the Garmin counterparts in the areas I mentioned.

    Thanks, I look forward to a reply!

    • Jaka

      @Matt
      The Ambit will be just about 5 years old very soon, so your timeline is about right. I had the Ambit (1) and now own the SSU. I was very pleased with the Ambit and a bit bummed at first when I switched to the SSU hoping it would do more in a month’s time from my purchase – I was a bit let down, but in general the watch did it’s core job of tracking my movement and heart rate. It has gotten a lot better since then and I think this last addition to the Spartan family is certainly up there as well.
      I haven’t owned a single Garmin, so can’t compare. But I have seen a lot of people gravitating towards Suunto because they were not happy with Garmins or simply got tired of them.
      Honestly, I don’t know how happy you’ll be and that is totally for you to decide. Maybe try both options out for a week or so and return them if you don’t like them.

    • Matt

      Thanks for the reply Jaka! Still not sure which direction I’m going to go with this. I feel like by the time I finally make up my mind something new will be out…

    • Hawker

      @Jaka is the Ambit really 5 years old? Rays first look was dated June 2014 and I remember buying mine in December of the same year it was launched, But it does not feel like a three year old to me. my gut would have said 4 years.

    • Jaka

      link to suunto.com

      The original Ambit (1) was announced in 2012. I made my first move with it on March 2nd 2013.

  15. alexei

    which chipset does it use? same as the trainer? why the gps ccuray is not that good here? im deciding bewteen those two…triathlon and open water use mainly

  16. Peter Heijnen

    Amsterdam has its own reference altitude, wich is called NAP (Normal Amsterdam Peil). In Europe there are several of these, all with their own reference. For example Belgium has a different reference which is 2.33 meters below NAP. The problem with altitude is that Earth is not a perfect circle, it has more a shape of a rugby ball. With 22 kilometers bigger in diameter around the equater than on the poles. Next to this, mountains are causing deviations by their extra gravity and so the water levels vary between different places around the world.

  17. Benjamin Tupper

    Any idea why Clever Training in the USA has it on sale right now for $341 (USD)? I just put in a pre order as the price is pretty amazing for this unit!

    • Ivo

      That’s an amazing price indeed. With the DCR discount code is is even as low as $307 (USD)! They simply listed it as a variant of the existing Suunto Spartan Sport Wrist HR, which to me looks like a mistake. I’d order it rightaway as well, if I would live in the US. Unfortunately, they don’t seem to ship to the Netherlands and clevertraining.co.uk does not offer this variant (yet).

    • Benjamin Tupper

      Thats a shame…yeah, I was confused because they have it listed as a variant of the Suunto Spartan Sport Wrist HR but that have that one priced at $499 (USD). Yeah, I ordered the Baro variant in amber and with the DCR code and some left over CT points I had I got it for $270 (USD)…not a bad deal! Just hope they don’t come back and realize the pricing is a bit off! The Suunto website has it listed for $549 (USD).

    • Benjamin Tupper

      Just got a call from Clever Training…they realized their mistake (darn) so looks like I am cancelling my order!

  18. ANGEL

    Hi DCR,

    I am still undecided regarding Garmin fénix 5 x and the new Suunto WHR & Baro. I previously own a Garmin fénix 3. Great watch to guide me and monitor my triathlon training. However I had a few issues with this watch, there were pretty silly excuses but they were important for me. The first one the lack of music and the screen resolution & brightness. Therefore after thinking about I decided to change to Apple Watch series 2. It is a great smart watch, I love the screen, music and look. However the main problem was its simple workout for me. Particularly the swimming workout as I am unable to transfer data to Training Peaks to check my workload from swimming.

    So now I am thinking about Suunto. I have never been a Suunto owner before so It is a new field for me. It has got quite a few point which are important for me. I think Suunto is more “sexy” than Garmin fénix 5x and the weight difference is an issue in Garmin. It is shame that they have no added music into them as I think this is a crucial feature for this type of watch, particularly for those long steady run where you could pair it with your AirPods.

    I will probably keep my Apple watch for work and music as I feel that as smart watch has not comparison with Suunto or Garmin.

    DCR do you think there is much difference between resolution screen of Garmin fénix 5x vs Suunto? I used to hate the lack of resolution & brightness of Garmin Fenix 3 despite its performance.

    DCR despite my priorities in terms of screen resolution and music, I am still undecided regarding Garmin fénix 5x and Suunto. I feel Garmin fénix 5x is in general better watch (with maps, Baro, ANT+, bluetooth & Wifi) than Suunto, there is not doubt about it but I feel that the following updates from Suunto will put Suunto on the top of the market. I understand that It is a chance I have to take, considering price and probable potential and I do really like the look of the new Suunto and I am still unsure.

    What do you think guys?

    Cheers and great review DCR

  19. lolokch

    Hey DCRainmaker which sportwatch is better ? Garmin 935 or Suunto Spartan Sport Baro ? especially GPS accuracy ?

    • Chris

      Read the above article for your answer…(cough, 935, cough)

    • Mauri Galvez

      It constantly appears this site is for Garmin lovers, not very open to other brands.

      After reading reviews, I decided to “upgrade” my Ambit3 Peak and bought a 935. What a disappointment. Terrible menu system, constant syncing issues, cheap looking apps abound, cheap feel for a $500 watch, and worst of all an AMAZINGLY poor display!

      Display looks like my old Sony Smartwatch 3 Android Wear watch. Even my Ambit display is superior. Commenters always touting “so many more features”, yet many of them are not critical and I’m sure fewer than 5% of users semi-frequently use these add’l features and even fewer significantly benefit.

      But everyone benefits from reliability, and an easily read and quality display. Additionally, my Ambit has been FAR more accurate in GPS readings.

      Not sure that the “new improved” Suunto’s are the answer…yet. But I’m not a gearhead that HAS to have the latest, I prefer something that works so I’ll keep using my reliable Ambit, and keep watching further development of Suunto, Polar, Garmin, etc and put the $500 into better utilized equipment.

      Aloha from Maui.

    • ano

      I agree with the statement that the site content and reviews favor Garmin ecosystem. Yes, there are pluses and minuses but it seems that at the end Garmin products always win. :-)

      I personally own a Fenix 5X (IMHO too expensive for all the bugs included) but would like to see more fair reviews of other competitors and unfortunately it is not in this site :-(

      It’s just my opinion, please don’t get mad now and have a nice day :-)

    • For the last three years, Garmin has released approximately 20-25 fitness/outdoor devices…per year. For the last three years, Suunto has released approximately 1-3 devices per year.

      Even Suunto themselves would readily admit that the Spartan series wasn’t competitive until this last spring with even their own older devices, let along Garmin’s devices. Correspondingly, ever bit of sales data you can find (be it analysis of what people are uploading to Strava, Amazon sales numbers, or the numbers I see), show agreement with that.

      Still, I cover all these devices and say what I think. If you look at my post on Suunto Spartan Trainer from just a few months back – I think that kicks Garmin’s but in the mid-low priced tri watch realm. But the Spartan Baro (this post)? That’s a much tougher pitch.

  20. Hopjesvla

    About battery life shown: this is, if i’m right with both HR and GPS enabled. So what about when just wearing the watch and only use the HR during the day? Is there any info about these stats?

  21. Stef den Elzen

    Great and helpful review as always

  22. Hopjesvla

    Is there also already a plan for a more in-depth review?

  23. alexei

    hi there ray
    have you tested for triathlon use? o.w. swimming?
    wanted to know if this is better than the trainer .. gps and hr wise…also i saw a video with trainer almost impossible to read on outdoors!

  24. Monica

    Can I set heart rate limits with vibration alerts while training? How does this compare to the Fenix 5 for performance measurements? Any advise about sizing for a woman’s wrist? I would like to buy the Fenix 5s but it is still bulky. The older forerunner fits better but doesn’t have the features I would like. Wrist based hr, hr vibration alerts, performance measurements, accurate elevation gain in the mountains, and closest to women’s fit are important to me.

  25. I was curious if you thought that Suunto would add an outside temperature module to this model? I know it has the barometer but as of now, doesn’t display the temperature. I’m not sure if it requires something extra for that function or if the barometer is all it needs?

  26. philip

    Hello. I’m curious if you think that Suunto will add an outside temperature read to this model? I figured the barometer would allow for that but not sure if the temp read requires an additional sensor. Thoughts?

  27. Femke

    Hi Ray,

    I’m into buying a new Suunto for (trail)running and triathlon.
    I want to buy the Suunto Spartan Sport (normal hr, no wrist). Do you expect new Spartan watch versions to be launched in the coming months? (And if so, which new features do you expect?) Or is it ‘safe’ to buy now the current Spartan Sport😉😊

    (Reason of my question is, I bought the Ambit 2S and 1 month later the Ambit 3 was released. With smart mobile connection / bluetooth connectivity, which I would have been waiting for if I knew on forehand….)
