I know this is a little switch of topic but I have been having trouble with my heart rate monitor. Ironically the place it works without fail is in the pool, the very place it may give inaccurate or no readings at all because of the chlorine. When I'm running I have to try all sorts of contortions to try to pick up any reading, so many that I often give up all together. Can anyone shed some light on why this might be happening? It also happens on the bike. It's a Polar F6 or some such other model.
