Have some fun in the travel section.
I travel a fair bit, both for work and for fun. Here’s a bunch of random trip reports and daily trip-logs that I’ve put together and posted. I’ve sorted it all by world geography, in an attempt to make it easy to figure out where I’ve been.
My Photography Gear: The Cameras/Drones/Action Cams I Use Daily
The most common question I receive outside of the “what’s the best GPS watch for me” variant, are photography-esq based. So in efforts to combat the amount of emails I need to sort through on a daily basis, I’ve complied this “My Photography Gear” post for your curious minds (including drones & action cams!)! It’s a nice break from the day-to-day sports-tech talk, and I hope you get something out of it!
The Swim/Bike/Run Gear I Use List
Many readers stumble into my website in search of information on the latest and greatest sports tech products. But at the end of the day, you might just be wondering “What does Ray use when not testing new products?”. So here is the most up to date list of products I like and fit the bill for me and my training needs best! DC Rainmaker 2023 swim, bike, run, and general gear list. But wait, are you a female and feel like these things might not apply to you? If that’s the case (but certainly not saying my choices aren’t good for women), and you just want to see a different gear junkies “picks”, check out The Girl’s Gear Guide too.
So cool. It seems like it would be difficult to keep the GPS connection when you breath, but I guess no different than a open water watch that’s constantly losing its way. I’m disappointed that it didn’t a chance to sync, but agree that, 5 months from Production, this is a pretty awesome state to be in.
I’m in for 1!

So I guess the main differences between this and the Iolite is the presence of audio cues and Bluetooth connectivity?
…and that the audio cues make the Marlin not legal in triathlon competition, while the Iolite is?
Yeah, which, are honestly pretty big things (in terms of differences). It was just so easy to transfer over the files and to do it via mobile is great.
Oh yeah, being able to control / interact with it using your phone seems like it would be MUCH easier.
But designing it so that it’s not triathlon race legal (I’m assuming; their kickstarter seems to assume this as well) makes it much less attractive. It makes your training open water swims easier, at the expense of training the specific skills you need in a race, where you then can’t use this device you’ve come to rely on.
So count me as one that would like to see this either cleared for use in a race, or another model developed that can be. The Iolite is better but at twice the price and without Bluetooth it seems a lot easier to just get better at open water swimming.
Any word on how this would work in and endless Pools.
I would love voice indications on how long I have been swimming.
Also… is this race legal? Having audio directions to stay on course would be a Hugue advantage.
I don’t believe it’s race legal, though, they probably haven’t approached any certification bodies yet.
I would think for visually impaired swimmers this would be a great device. Also I do agree with Ray I think they missed the boat not having this be a mp3 player as well. The amount of people that want a swimming mp3 player vs people that what some guidance in a open water swim is pretty huge. But this looks to be a great product and for 90. a great deal.
Interested in how it performs. It might be a game changer. Imagine during an ironman, one doesn’t even sight, rather simply follows the audio instructions. That could save a few seconds/100 yard, meaning a few minutes in an ironman!
I typically never watch your videos, but happened to click on this one. The underwater swimming shot at 2:16 is great! I would have been watching all along if I knew we were getting that kind of production value.
I have zero experience with video, but it seems like it must have been a pain to position the camera at depth?
Thanks!
It was just a funny little outtake that I figured I might as well include in what otherwise might be a bit of a boring video.
In this case I just used a mini gorillapod tripod, which is flexible and easily fits under the longer swim shorts. I also locked out in that there were some rocks in that area, so I just swam down, plopped it in place, and it stayed put. Sometimes with currents and stuff they fall over, but this time it stayed in position.
(Sidebar: On a swim the next day I actually lost the cam without realizing it. Sad panda. Spent about 30 minutes creating a search pattern for it to eventually find it down in some seaweed. I make a habit out of swiping my leg every few strokes for exactly this reason when carrying a camera there. But in this case I was sorta swimming backwards a bit between two shots and put it in a weird spot.
Astoundingly, this is the 4th time I’ve had cams go rogue mid-swim over the years, and I’ve somehow managed to find/rescue them all. The pinnacle of failure-gone-win was in Thailand a few years ago and a GoPro fell out of my pocket getting into a boat from the water. I didn’t realize it till an hour and another island later. The guy was awesome enough to go back to this random reef and we actually found the darn thing. Crazy.)
Well very cool that it worked out so well. Makes me want to pick one up (something I had never really considered doing) just to play around with.
Ha. That was exactly my thought when I watched the video: that in the time it takes to get the shot that thing could disappear. The perils of smaller and smaller technology!
Very interested as a blind swimmer
Holy crap! You swam all the way around Round Island!! I’ve read that those waters are infested with man-eating sharks that will rip your leg right off and swallow it whole!!! :o)
Thanks, as always, for the great mini review. Wish it was race legal as well.
Something wonky with the sound on the video – the level decreases significantly in the transition from swim to demo of the app.
Hi Ray!
Definitely an interesting product. Do you have any insight on connectivity to fitness platforms (Strava, Garmin Connect etc.) or know whether Platysens’ has plans for developing these?
Ray, what is your personal best for 1500m swim?
Not 100% sure off-hand. My guess is openwater without a river (i.e. not downstream or anything), it’s about 22-23 mins. I’d have to go back and look at older race reports to see. SCY a bit faster of course.
Swimming isn’t exactly my greatest sport, and since moving to Paris I swim rather infrequently given you can’t openwater swim legally anywhere in the city. And the pools are a total mess (15-20 people per lane).
On the bone conduction communication path, can other people hear it? Maybe a tinny little buzz like when people have their ear buds jacked up to deafening levels?
They had some quality issues and switched to a different plastic vendor a couple of months ago, but have been good in communicating. April seems to be the new mass production/delivery month.
I’ve just received my Marlin and have taken it out for the first time.
– I made the route before hand (nice 3km swim halfways arround Amager Strandpark (DK)
– It went to sleep while i was taking on the wetsuit and when it was time to go with the other fish it took a long time to get a satelite fix again. Lost the first 500 meter that way
– I then skipped the first 2 waypoints – and accidentally skipped the the third because I was at the second waypoint but i did not get a confirmation that it had acknowledged it. Luckily i knew my way around and it found the 4th waypoint just fine.
– I then passed the 5th waypoint to far to the sea and it wanted me to go back to it catch it and i turned it off.
When i learn to use it i think that i’ll like it ;-) When the intensity rises my ability to sight the route gets really bad. I hope that the Marlin will help me correct sooner so i get better at swimming a straight line without having a black line to follow
But it there a forum somewhere for users ?
(besides the support site) link to platysens.freshdesk.com
– On android I can’t find the waypoint radius settings ?
– Any news regarding their plan to allow export of their data ?
(It is pretty limiting only to have it in their app on the phone)
I can’t even get it to pair with my S8. It paired with iPhone but the app is unpolished.
I’m using a OnePlus 3T
I asked about a forum for users on their facebook place and was just directet to their support forum.
Quickly open 3 tickets and they have responded to 2 of them within half a day.
To export an open water swim you just have to press export in the lower right corner of the map and you can email the GPX – unfortunately there was some wonky gps data in my swim so had to send it trough fit file repair tool to be usefull …
I think that it would be useful to have a place for user to user discussions and not only the support site.
So i’ve opened a group on facebook for Marlin Users: link to facebook.com
If there is a better place i’ll just delete it again …
The Android App was updated today
1. show correct pool workout distance and calories
2. fix open water workout no map bug
Same swim as before – just a comparison between my fenix3 and the marlin.
I was swimming with a group and we had breaks for the rear to catch up every ~500meter.
It is clearly visible that i was not good at keeping the Fenix above water while stationary as by the bridge in the upper left and by a boye further to see.
Looking forward to my next swim with both devices …
I had to delete app and reload then it pained very easily
This week i received my Marlin and had my first swim. Initial impressions:
– Build quality is fine, although the cale looks a bit flimsy
– Audio is also okay but don’t expect miracles. you have to carefully listen or you will miss parts, especially since you have usually all kind of “water noise” when doing a turn.
– App seems so far a closed system, its not possible to get data out of it
– I am missing the option that the device tells me my average pace but this is the metric which i am very used to
– Main problem: I am very disappointed about the bad accuracy: I got a lot of false positives (meaning additional/wrong lap counting). And by “a lot” we are talking about >50% more laps than i actually did. I know its not my stroke because my Garmin 920 counts almost 100% flawless.
Support theys i should then them additional data (“diagnostic mode”) and they will improve the software. So lets see.
In OW mode it is possible to export your track as gpx – it will send you and email. I’ve missed it until i made a ticket of it in the support system. when looking on the workout track you can press export in the lower right corner ;-)
Yestedays swim with my Fenix3 and Marlin
GPS tracking point
58 Fenix3
3247 Marlin
It just shows that the accuracy is of course much better if you keep a GPS device above water most of the time ;-) I’ve made a similar comparison before with my forerunner 920 and a GPSmap60 in a ISHOF SaferSwimmer buoy.
The Fenix did loose GPS completely for 500 m between ~2000 m and ~2500 m.
The first part of the marlin log is on shore – probably ~50 m before pressing start on the Fenix and start of the swim
But back to the function of the Marlin. Unlike last week where i accidental selected pool mode on my way in the water i actually had both the right course and started it with a GPS fix before entering the water.
But i had issued with getting close enough to my waypoints. At the moment the proximity parameter is not available on Android and I know for sure that I was within 10 m of most of them. But I still had to press the + for 2 seconds to get it to direct me to the next waypoint.
So in the end it did not recognize my swim as a known course.
With regard to the timestamp i first thought that it was just an timezone difference – it looked to be just 2 hours off. But the App shows the time as 1:02:32 while the exported GPS file just lasts 54:06
I was also wearing a Garmin Fenix3 and it recorded 58:57. That seems right as well as the 1:02 that including waking into the water and getting back up.
When i cut the ends of the Marlin tracks on shore so that the endpoints match the workout i end up with only 52:40 – i can only wish to be that fast for 3km ow :-)
I report what i find to their support and they also answer
With regard to laps being inaccurate – have you tried to calibrate it ?

This week I did the firsts open water swims with Marlin.
The precision seems good to me.
The volume is generally good but when air and waves grow it becomes difficult to ear messages.
The main issue I found was the fact it gives speed advice in Km/h and that is completely unuseful!
I hope they will soon add a more classic seconds for 100m data…
Has anyone else been having issues syncing their workouts to the app to view the route and other swim metrics? Everything else has worked pretty well both in the pool and open water for me.
Hi Ray
Wondering if you’ve done any testing with this now it’s a more established platform?
Is it a recommended buy or are there better/cheaper devices out there?
Im blind and I have two of theses.. we use them at the lake Open water swims. It’s awesome I don’t have to be tandem to someone else had I know I’m going where I need to be going. It’s loud you can hear it well with the bone conduction. It’s very accurate and keep you right on the line … it’s amazing it really is really is.
i sold it after some playing around. It certainly matured over time (software-wise) but it doesn’t fit my usecase (which is mainly indoor pool).
I currently use a FR935 which tracks my swims and does everything i need. i am very used to pause/unpause during breaks, it’s basically a reflex. Having to think about one additional device is additional stress for me and sometimes i forgot to restart the marlin again after a break.
What i would love to see in the future: A wireless addon-device for the garmin watch which is basically an “audio-extension” and would rely on the watch data. Of course this would not cover everything which Marlin does.
Thank you, DCR. What a great review for the Marlin!!!
DCR I’m old school and still haven’t figured out how to use PayPal except through my credit union which only allows me to send money through email PayPal. Can you send me your email so I can send you a 20. My email is somos99@yahoo.com.
Your Marlin review was excellent. Thank you so much!!!
Eduardo ❤️??
Platysens is closing – Received this email :-(
Dear VIP Marlin customers,
Thank you very much for all your support in the past few years. We are sad to announce that our company will be closing soon. We will stop our operation by the end of August 2021.
Meanwhile, we will keep the Marlin app server up and running for one more year (i.e. till August 2022), and we will launch the final version of the Marlin app soon such that users’ workouts and training programs can be stored in their mobile devices locally even after the shutdown of the server. We hope this can allow you to continue using the Marlin even after the close down of our company.
Sad to see them go. Even trough the tracking is not as accurate as i would like*, i really like to have status read to me once a minute. I don’t usually use the navigation part. * My swim2 is much closer to the real distance., The marlin typically overshoots with more than 10%
