Hi,

I got my new X6HRM yesterday. I tried to to monitor my heart rate and didn't like what I see from the watch. When I was rest the watch reads between 68-72, when I test the pulse by myself it is about 60. I am a marathon runner, not in the shape I want to be, but I was able to complete the half marathon in 9 minutes pace 2 weeks ago. I guess my heart rate should be somewhere between 50-60.

Today, I tried to run with it. My heart rate was jumping between 90-180. The watch could be at 180 now, then one minute late, it becomes 90.

What is wrong?

Thanks!
