Heart Rate Monitor Issues

Hi,

Having a few problems with my HRM. The last couple of runs I’ve been on, my HRM only goes up to around 50-60bpm. Normally I get up to 130-170 sort of thing. I’ve tried washing the strap, adding a bit of water to the strap before the run, made sure it’s not in % max HR showing but actually the bpm.

It just won’t budge from the 50-60bpm.

Anyone had this before? What’s the issue here?

Battery dying in the watch or the chest strap? How long have you had it?

I’ve had it for about 18 months. Bought it from the USA from Amazon.com

Have you lost weight lately? Same thing happened to me, I lost 30 pounds and it picked up but stayed in the 50’s… figured out the strap was just to loose.
