I have been using Forerunner 902xt watch. Just hired my first duathlon coach and he wanted HR graph, so I pulled HR monitor out. Readings were abnormally low.
ordered a new chest strap, readings on watch & bike computer show up then disappear....on and off...on and off. I reached out to the company that sold me the chest strap, they assumed after a battery change in the chest strap but it was a faulty sensor. New chest strap and monitor arrive today, same exact problem.
Having been on blood pressure meds for 20 years, I have been told many many times that my heart rate is very hard to hear. Not sure if this is relevant, really hoping that’s not the issue. My Apple Watch seems to read my heart rate with no problem.
I have attempted to get a consistent reading both while sitting still and while up walking around, and the display still goes in and out. Seeking a solution so that my coach can see the progress of my training.
