Long term use of the H10 has uncovered a few issues.
- Pairing continues to drop on occasion, requiring a hard reset and unpair + repair to devices. (AWU & Wahoo Roam V2)
- HR drops throughout steady state efforts or unrealistic HR readings during intervals. Pics below
- Support through polar website suggested various troubleshooting tactics (which i’d tried) and resorted to asking me to send it in for review + repair. I’ll likely do this in an attempt to get a new unit and avoid these issues, though i just think its not a good product vs truly a defective unit.
I’d no longer recommend this HRM.
800m run repeats shown below with reps shown by the increase in pace (blue)with the 1st, 4th, and 6th reps showing a rather expected HR curve and reps 2,3,5 showing unrealistic dips followed by sharp climbs to the expected levels.
Shown below the last bit of an 8 mile Z2 run where pace stays relatively consistent and HR showing sudden jumps to the tune of 20bpm. My watch was saying ‘above zone’ & ‘below zone’ in pretty quick succession while my pace was exactly the same and minimal change in elevation.
