T-Rex Ultra 2. Why the HR accuracy while running is so broken?
If you watch the TQS review of the Fenix 8, you will see similar problems to the ones that the T-Rex Ultra 2 shows. Heavier watches simply have more misses than lighter ones.

Amazfit Cheetah 2 Pro vs Garmin Forerunner 970, Urban GPS test
