Hi everybody,
I'm looking for solution to a little annoying problem I noticed using my HRM dual now that's cold outside.
I find the HRM dual very accurate, it's stable and the connection is instant and stable using my F5, but when I'm wearing a vest like the Nike Aeroloft or something similar on top of my t-shirt, after usually 15-20min running, I get crazy readings like 180bmp while I'm actually 135.
I'm 100% sure it's caused by electrostatic charge generated by the vest rubbing on my shirt while running: my t-shirt is also a dry-fit 100% synthetic, but as soon as I open the vest, or if I'm not wearing the vest, I'm not getting this problem.
Any idea how to solve this? Maybe a cotton or rubber patch over the sensor?
