HR accuracy issues

Is there anyone else having issues with HR readings?
I noticed that my HR was "stuck" during workouts, and would never get any higher than ~100.

I've tried wearing the watch in maybe 10 different ways, other arm, removed all sweat, tightened the strap, etc.. nothing worked.
All software is up to date.

I had a friend nearby who has a FR 235 and that watch reported HR 142 while mine was displaying 101. I think that's different enough to say that it's not working.
It sometimes work , and sometimes not. Can't make head nor tails of it... ciq.forums.garmin.com/.../1480558.jpg

    I have tested. Same problem again with CrossFit sessions....

    Mine seems to have been fixed, but that’s only based on a single run since the 3.70 update, but I’ve never been able to have a run that didn’t have cadence lock problems. The difference in the graphs is very obvious. Very run I did previously was like the top graph. The 2nd one is post the 3.70 update and is accurate. Also note the lack of downward spikes.

    Mine still sucks. The HR numbers are higher than before, but still lower than true. All I want is for it to accurately broadcast my HR to my Wahoo Elemnt when I ride. At my age, I need to keep a close watch on my HR, but I can't rely on my 245m. What a POS. So I'm going back to my Scoche Rhythm+ HR armband.

    Having previously sorted out the problem through their helpline service, this update has quite definitely stuffed it up again. I did a hard run for 4 km and would expect HR of 155 and it was HR 80....

    Same thing. On run activity it shows more or less adequate value, but for indoor training never get over 100 bpm

    I had decent but not outstanding wrist HR readings during running with prior FW.  3.70 has broken that.  Readings now 30-60 BPM too high.  Unfortunate.

    Anyone got any updates on this? My watch just updated to V4.0 of the firmware, but I have had the opportunity to test it yet.

    Nothing. It looks more like algorithm than measure. For example for me on long run, after 15 km it shows 180 bpm as if I was running sprint

    Are you on V4.0 FW?

    From yesterday i have a problem with hr reading, yesterday with hiit i was at my limit and the watch said i was at aerobic pace, basically 140bpm, while before the same effort and exercise put me at 190bpm.

    Today with a run, running at my full speed, gave me orange zone around 163bpm while 3 days ago the same effort gave me red zone with 190bpm.

    Seems like hr readins screwed up.
