Mine seems to pick up my resting/relaxing HR just fine after I’ve put the stap on (wet, of course). However, after I stretch and start to run, the HRM doesn’t seem to want to pick up my actual HR…I know there’s a lag, but this is a lag of several minutes.
After about 10 minutes, it starts to sort of work, but midway throuh a workout, it will start showing a HR of between 208 and 240, which I know is not physically possible for me without my heart exploding out of my chest cavity. The HR shown then bounces around, to the point where this thing is no longer useful as a training tool.
I’ve had a jeweller check the chest strap battery, and it seems to be fine. Anyone else have this issue?
Cheers.
