HRM Dual Heart rate stuck at 72

I have the HRM Dual. I just bought it two weeks ago. I've gone on about 9 runs with it. During my last run, it worked perfectly for about 45 minutes and then my heart rate descended to 72. It has not moved since. It has been several days and it is very clean. It has no problem hooking up to my phone via bluetooth and connects just fine as soon as I strap up. However, the heart rate is stuck at 72 and doesn't move. Any ideas?

  • Same problem here.  Worked normally for two bike rides, then will only read 72 and disconnects after a short time. ANT+

    Even though it was a new unit, replaced battery with same results.  Used my original Garmin HRM with strap and the old one reads fine - not the strap or battery.
