I am wearing my Fitbit under my drysuit. I’m pretty sure that it won’t be able to measure fin kicks accurately, otherwise I would have been in a different country after the dive.

I agree on the water proof arguments. My Charge4 is said to be water proof until 50m, I have to see how that will work out over time. The main reason I wear it is to measure my heart rate. It would be cool if I can import that into a log as well, since my Shearwater Teric doesn’t have heart rate measurement possibilities.
