Subject: RE: Polar HRM questionCould be a number of things.... If it was at the very start of the run, the strap might not have been picking up your signal clearly. I have to break a light sweat to get consistent connectivity, or use a gel like buh-bump. If it was during the run, it's either interference - which can be caused by many things, loss of connectivity to the strap (like if the strap slips down too low), or the battery in the strap. Hard to tell. |
