After the latest firmware update my HRM Pro shows as two separate sensors - HRM and FP (indoor as default). I would like to understand which is a better option for treadmill. a) Using my Fenix 5 for pace and distance like I always used to or b) using HRM Pro for pace and distance.
I fail to understand the purpose of having this feature in an HRM when a watch can already record pace and distance using GPS for outdoor running and using inbuilt sensors for Treadmill running. Does it offer better calibration?
