Anyone have experience with a reliable HR belt that would work while freediving & training?
My basic Sigma belt will not register anything below HR ~40, which is useless when training. We'll at least it tells me when the dive reflex starts but nothing after that...
Preferably it should also link up via Bluetooth or ANT+ so I can use it in other sports as well.
