Title: Transmits poorly
Review: My husband has the old style Polar chest strap (battery not replaceable) and it works like a charm after 2 years. Mine only transmits a signal when it is in the mood. It reads my heart at 0 in the middle of an intense workout or randomly says it is over 200 when I am not even moving... or it will get stuck at a number. Then it will spontaneously start working again. When I use my husbands chest strap with my watch it works fine, so I know the problem is in the in the strap not the watch. It is a source of constant frustration. I have replaced they battery several times and follow all the instructions from Polar. It seems like moisture may be able to work into the battery chamber causing it to short? For an expensive piece of equipment to work maybe 20% of the time is a disappointment!
