Suunto Race S too high HR
-
I have a new Suunto Race S that shows way too high HR readings during exercise. I compare it to my garmin w/wo a chest strap which are pretty similar. Also just exertion based it’s 30-50 beats too high, i.e. unsuable. Is this a common problem and any way to fix it? Right now I regret buying the watch.

@David-Kleman same problem for me. HR is only accurate for me during total rest (Sleeping, sitting still…). As soon as I move my arm or even only my fingers (typing on a keyboard), the HR increases slowly and locks to higher heart-rates. Sometimes even double the actual one. It almost instantly recovers if I take of my watch and put it back on or it slowly recovers over time if I do not move at all for approx. 1 minute.
Not only the sensor is bad but also the algorithm seems to favour fast increases above fast decreases. Therefore, misreadings due to movement (high values) seem to establish quickly but correct (low) readings afterwards are ignored and HR recovers to correct values too slowly again which makes the bad accuracy even worse. I tried everything that is recommended for OHRs and never had these problems with my previous forerunner and vantages which were spot on for normal daily use and light activities like hiking or steady and slow running under easy conditions.
Therefore, I never even dared to try the OHR during exercise since I anyway always use a HR strap during sport. As OHR readings during sleep are accurate, I in the end decided to stick with the Race S as the new Garmin alternatives are way too expensive. As daily tracking is so bad, recovery and resource metrics might not be as accurate as supposed but I see these metrics anyway more like a fun gimmick.
But before ordering I never expected the OHR reading to be a problem during normal daily tracking as this was never an issue with any other watch from other brands over the last years. Probably would have not ordered it had I known that before.
