My HRM-Pro, that I've had for about 3 years, has a problem with the battery draining. I'll go on a run, sweat a lot, and then it quits working. It's missing the red oblong gasket that goes on the outside of the sensor. But before that it was doing the same thing. I sweat excessively (and I live in a hot climate). This $130 is useless if it won't stay on long enough to get any data.
Does anyone have a spare oval/oblong shaped gasket?
Has anyone discovered another way to seal it to keep moisture out of the battery compartment?
