Did a first run with my new F5 today. Wore it as described, tight enough to stay snug but not too tight.
Was disappointed with the results, look at how it's way off at the beginning an end:
I have had the same Problem with the OHR.
But after an Upgrade to 3.22 and a Reboot - it is working again, as it schould!
I have tested it against the chest strap and after two runs the OHR readings are bretty the same as the chest strap readings!
I've decided to wait a bit before returning my Fēnix 5, hoping software updates would solve my issues. I made a test last Monday without success... After a few kilometers the heart rate bumped to around 160 and wouldn't move.
I switched out my first Fenix 5s because I decided the white one would get dingy. When I got the new one I realized how janky the first OHR was. This one is more accurate, and no skips and only an occassional stalls.
After updating to fw3.30 still the same - for running it seems to be ok. But on all other trainings (weight lifting, indoor rowing, crosstraining...) the readings are totaly bull... i've tried - shaving my wrist, to loosen or tighten the watch band, wearing the watch away from my wrist, wearing it turned by 180deg on my wrist - nothing seems to be stable...
A friend of mine also says the OHR from his old F3HR was better...
Atm i'm lazy of testing... pull out my HRM-RUN4... :confused::mad:

GARMIN - if you read this - please do anything...
Haven't heard from any OHR which does well with those activities though... Anything with flexing of your hand/wrist/fist has a bad influence on OHR. Even biking can be very tricky from what I know.
It does suck but IS known in general overall so I'm afraid there's not much that can be done about this (wouldn't mind to be proven wrong of course ;) )
Sounds logical to me - but because of that i've also chosen a position three fingers behind my wrist to avoid of any kind of movement in the area of the OHR...

Yeah, that sounds fine... And almost uncomfortably tight? I can imagine the weight of the fenix5 making it more prone to sliding/moving a bit as well.
Other tests might be on the inside of the wrist, perhaps even higher up the forerarm (for me the strap would be long enough for that... not that big a guy here ;) ) and trying it on the other arm. Then again, if these things work it is still not optimal and not the way you'd like it of course. But could at least help clearing things up...
I have had the same Problem with OHR and Cadence Locking - but after FW Update to 3.22 and now also with 3.30, the OHR is working great! Touch Wood, but no Problem at all!
So this is not an generell OHR Problem! One Thing, that can also cause this symptom, is cold Temperature.
I've found the OHR on my Fenix 5 to be surprisingly accurate during running activity when I tightened it so tight it's uncomfortable. It's nice to know it works for the rare occasions I forget my hr belt but as it doesn't really work reliably for every type of exercise I almost always use a belt for its superior accuracy and reliability.
What I am disappointed about is the all day OHR measuring accuracy and dropouts.
When I'm fairly inactive sitting or light walking/moving it does somewhat of an okay job measuring the hr but as soon as I move more it is not accurate. I've tested this with starting an activity and using the Auxiliary Heart Rate data field with a Garmin HRM Tri belt. The OHR shows constantly 10-20 beats less than the HRM tri, this is during a light activity where HR ranges between 80-120. Usually the OHR sticks to a steady 90 where the belt reacts to spikes in hr, so the average might not be so different but it misses on the min max values.
I also get constant dropouts (blank gaps) in the all day heart rate. I think there is two main reasons for this: first, the watch is so heavy that it moves around a little bit with every movement unless you strap it so tight your hand starts turning blue, and second, the optical sensor is too flat against the back of the watch and the wrist bone easily elevates the sensor a little causing light to get to the sensor and thus not getting an accurate measure.
I'm coming from fr235 and I find it to be much more comfortable and accurate with all day readings(although ironically they advertised the Fenix 5 to have much more accurate all day readings). Now I'm debating if the lighter weight of the 935 would yield in some improvements in this regard.
Does the flashing leds of the sensor mean that it is not seeing the current heart rate? Mine does this all the time but it still seems to show the current heart rate in the widget.
