Andrei over 3 years ago. Hello, I have a Fenix 6 Sapphire with the latest beta firmware. I've noticed that when I'm doing treadmill activity, my heart rate is around 80-90 bpm. The watch is worn correctly, pretty tight and higher on the arm. I am doing the treadmill after the Strength workout where the heart I start the excersice and only if i choose the option of broadcast heart rate it shows the heart rate to my watch, and only for 20 minutes. When i rest and try to see the heart rate from hrm dual same happens shows only for 5 sec. I pair the hrm dual with an other fenix 6 same thing happen. 8waUjg.
