Since hurting my Achilles tendon, I've been water running, often holding light water weights or a belt. The problem is that the HR is terrible. I sort of need to see my heart rate live to see what zone I'm in, ETC. I don't know if Garmin uses a different power profile for the HR sensor when using pool swim, or how to duplicate that for Water Fitness. There is no Water Fitness activity available on Garmin so I just used Cardio.
Any tips would be appreciated. I'm thinking of using my scoche HR band right next to my watch. I know bluetooth or ant+ can travel about an inch or two under water, so it might work? I know my Form Swim goggles for lap swimming using the polar HR works with it being about an inch away.
Thanks
