Hi folks. I have no idea what category to post this in, so I put it in everything else. I have a heart rate monitor that I wear when exercising. It is the Polar FT7. It is supposed to work underwater (swimming). As soon as I enter the water the watch loses communication from the transmitter (transmitter is on chest strap). I am wondering why this happens. Could it be because of the salt? I have not tried it in a non-salt pool so I do not have any basis for that assumption. If I stand in the pool so that the chest strap is above water, then raise the watch above water, communication is established again. Any ideas?
