For some reason my year old HRM-Tri has suddenly stopped working and won't be picked up by my 645M. I tried replacing the battery but it still won't work. It was already on its 2nd battery.
Before I go out and get another HRM-Tri or HRM-Run, are there any better heart rate monitors out there? Doesn't have to be Garmin. Not too bothered about running dynamics, just want accurate heart rate.
Also, is there a way to disable the OHR during activities and use it only for all day tracking? As my HR activity data is completely useless, no matter how I wear my watch.
