Suunto Race S optical heart rate sensor accuracy
-
Hi everyone,
I was wondering if someone can share some further experience regarding the new optical heart rate sensor accuracy on Race S when running. Being aware of all the possible variable influencing it, nevertheless my own experience is pretty bad. Under the same conditions, sometime it is giving correct values for a couple of KM at the same pace and then getting crazly high for the rest of the run, or it starts bad, then stays right for some km and then get again bad in the end.
I’m of course not expecting the precision of a Polar H10 chest heart rate sensor, but coming from a Garmin Instinct Solar 2, the Sunto Race S wrist optical heart rate sensor in comparison is a mess, at least for me.
Any feedback is appreciated.
Thanks

@dariof I observed optical HR behavior that can be characterized as cadence lock.
On two occasions when trail running, when hiking up a steep grade, HR was stuck at 60-80 bpm for long periods of time, which is very close to step rate. Also, on few occasions when running it was jumping up to 160-180, which again is close to step rate.

@dariof yep, my experience with the Race S hasn’t been good at all. So it’s permanently paired to either my H10 or my Verity Sense. My old Instinct (original) was actually really good as was my Fr245 Music which was probably the best OHR I’ve ever come across. But the SRS is still a fine watch with many great attributes.

My experience with the Race S OHR is very good, better than S9 Peak and S5. But I have no Garmin to compare and wear the watch tight above my wrist
