Product Description


The FINIS Swimsense® (Powered by SportSense®) is a groundbreaking training tool, which captures critical performance data. Improved by a new iiM technology upgrade for better accuracy, the monitor straps onto the wrist like a watch and uses accelerometers, magnetometers and patent-pending proprietary algorithms to identify your swim.

Record time, pace, distance, stroke count and rate, calories, and distance-per-stroke.
Analyze your performance on the device with interval times, pace times, distance (meters/yards/laps), stroke count, stroke rate, distance-per-stroke and calories burned across all four major strokes. Performance data can then be uploaded to the free FINIS Swimsense Training Log at Swimsense.com for additional analysis and historical review. The Swimsense Performance Monitor provides a revolutionary degree of information, which is key to tracking and improving your swim performance.

You might not swim like an Olympian, but now you can train like one. This innovative monitor, used by Gold Medal swimmer and World Record holder Jason Lezak, uses internal sensors to detect what stroke you're doing--even accounting for changes between laps--and then record distance, speed, lap counts, and cadence.

Never heard back from Finis tech support.
You can only transfer the data via Swimsense Bridge to their website that crunches the data for you, though if that is down (or you don't have wifi) you can't do it.
David Griffiths
Conclusion: Swimsense - miss-counts strokes and distances, e.g. 4 for 16 strokes, 25 yards for 50 yards.

This devise does not work correctly way too often. I did not believe some of the reviews but they were correct it misses a lot of laps (or sometimes splits the lap into two) thus making the usage close to impossible. I tried to use it for my training sessions (like 4*50 with 15 sec rest) and it added 25 yards to 2 out of 4 repetitions. The idea is interesting, interface is good and web site is nice but the fact that it is so inaccurate breaks everything for me. I sent mine back to Amazon for a refund.

I must have been one of the first buyers of this item and it shows. The idea is great, the design is good but needs some improvement. On one side there are minor glitches that will keep improving via the upgradable firmware. Glitches such as getting pacing data in feet/second despite having chosen meters/second in the setup, not being able to choose the correct age or weight but in multiples of 5, not being able to export or correct training data from the web app, etc.

Then there are the major issues. Battery will last for two one hour swimming sessions at the max. What is surprising is the rete of battery consumption in watch mode, which should be equivalent to a regular watch, so the best option is to turn it off when not in use. The other major glitch is not having heart rate measurment.

I don't want to look negative, this is a good piece of equipment and would buy it again, but it shows that swimming computers are a new breed of training computers and there is still a lot of room for improvement.

I've bought the Swimsense watch immediately after it was available in Europe. Since then I swam a few hundred kilometers wearing it. Basically unless I forgot to take it with me I used it.

I had some problems at the beginning with stroke type recognition but as the firmware was updated these problems disappeared almost completely. I also had some problems with the watch itself, but excellent support solved it quickly by sending me a new unit. I don't really like the web application which is the official way to manage your workouts right now, but since you can export your swims to a CSV file I created my own site that lets me see exactly what I want so I'm happy. Coming back to the watch itself, it is really important to have a strong push off and not to take pauses as you swim. While nobody does that intentionally you don't always have your own lane and then it becomes a problem. I think setting your minimum time per 25/50m would solve half of these automatically as now I sometimes end up with a 25m breast swam in 10 seconds which is something I will never achieve in real life :)


- It does what it's supposed to do and it does it pretty well (counting laps + recognizing stroke type)
- You can get a decent idea if you are improving or not.
- It lets you export your workouts to CSV for further analysis using your own software!
- Battery life is really good


- It does not let you count laps made doing drills, not even a simple push-counter.
- As a result of that some people are discouraged from drills and they are so important!
- New features which were promised a long time ago still haven't been delivered :/
- Online application needs a facelift and a lot of features!

I have been using this watch for 3 weeks. I am a former competitive swimmer, now swimming masters and training on my own, 53 years old. I swim interval workouts, as well a long endurance fitness swims in a 25 yd pool. I am primarily a middle distance free style swimmer. Occasionally I swim in a wetsuit. I use a small paceclock on deck for interval swimming sets.
I have to say, this watch does several important things for me I could not do very well on my own:

1. log total yards, and accurately count laps on longer swims.
2. track and record pace and strokes on workout sets, allowing me to focus on technique and intensity

What I DO NOT use this swimming monitor for:

1. a regular watch
2. a lap counter that I can see while actually swimming/moving ( although i have tried many products for this purpose, there is not one that can be worn and seen easily while swimming)

I interface this watch with an iMac computer. At first, there was a hiccup with uploading the workouts, but that was because Finis had just changed their software from swimsense to streamline bridge, (the paper instructions in the box did not reflect that).Customer service at Finis by email, resolved that within 24 hours.
Also my paper manual, an even the online instructions do not mention a valuable new feature embedded in the watch: automatic interval swimming detection (as a configuration option). This is a unique feature that allows for swim sets to be recorded accurately and automatically
(such as 10 x 100 free on the 1:30 or 10 x 100 I.M. on the 1:45). For swimming tight interval sets this feature is invaluable, as you don't have to stop and pause and then restart the watch during intense swims.
