I m typically a large fan of finis gear.
Waterproof swimming activity tracker.
They also track swimming stats like lap counts pace and total duration.
However its heart rate monitor is not as accurate when under the waters.
There are also a few different kinds of fitness trackers.
Finis swim sense waterproof fitness tracker.
I find them to a be innovative when it comes to creating products for competitive swimmers from their tempo trainer pro their agility paddles to their excellent underwater music player the finis duo.
The tracker is waterproof and swim friendly to a depth of 50 meters.
So for instance a waterproof rating of 2 atm would mean that the device can withstand a depth of 20 meters.
This activity tracker is waterproof up to 30m so you can wear this during swimming.
The slim design makes it unobtrusive to swim with and out of the pool its size and profile make it another tracker that s easy.
The charge 4 versa 2 flex 2 and ionic are swim proof to 50 meters.
