Hi, I have recently switched from Versa 4 to Charge 6 and the heart rate accuracy in the Charge 6 is so much better! I had a Versa 2 and then a Versa 4 in the past and both of them was highly inaccurate in the heart rate reading, with the heart rate never going above 120 bpm even on high intensity activity (where my rate was clearly above 160 bpm).
I wanted to know if anybody had the same experience, and if you had multiple Fitbit which one you found more accurate in tracking the heart rate.
Thank you
