It requires no wires and is submersible to one meter.
*Compatible with most cycle computers and heart rate monitors currently on the market. Targeted MSRP: $179
There were a couple of posts here spring of '05 but no real info. In looking this over, I can’t see why I would want one if, for example, I have a top of the line unit from Polar. Am I missing something here? Also, fyi, they are on e-bay for about 50% of the msrp.
