I recently recieved a Polar brand heart rate moitor as a gift. I noticed that is was water resistant to 50m so I took it out free diving. It was interesting to see my heart rate gradually slow down as I dove progressivly deeper but at a certain depth (about 40 feet?) the rate went to zero although I could still feel my heart beating.
Has anyone else tried using a heart rate monitor while freediving? If so, what were your observations? Is there a better model perhaps than the one I'm using?
