Anyone STILL having heart rate accuracy issues with their Fenix 6?

I contacted Garmin about low heart rate with cross country skiing when using OHR. They acknowledged the problem. I sent them all necessary data from my watch and those were sent to developers. Whenever you're having issues with OHR when doing some activity, you should contact Garmin. Nothing will happen if you only tell about it here. Just FYI if somebody does not know that yet.

Went for a quick test run with the H10 vs 6X again. Had the 5X on my wrist but unbelievably forgot to hit record before I ran off. I will repeat tomorrow with all three, but for the moment this is the reading of the 6X and H10. The 6X just locked on to 150 and did not want to move at all. The big drops are where I paused the activity and started again to see if it would track HR whilst already elevated up to peak again.

Yeah, this is really bad. I'm going to return tomorrow. Unfortunate. I really want to love this watch. Just not worth the hassle, especially at the $800 price point.

Got a Fenix 6 Sapphire this week. Hiked up Scafell Pike yesterday and apparently my maximum heart rate was 110 bpm. This just doesn’t work, how is Garmin getting away with this? I will have to return it as not fit for purpose, especially when Garmin claim their wrist sensor is “cutting edge”, well apparently not, my Apple Watch never had this problem, nor did it think my heart rate was consistently in the 90s when resting on the sofa.

Looks like this has been going on since October, so presumably this can’t be fixed in firmware. I think they should do a recall.

I think they should do a recall.

unfortunately the watch works for a lot of people (works for me) but it doesn't for some.

Probably is the situation with the majority of watches and brands out there.

So a recall would be impossible and probably a fix either. 

Same here... Mostly fine when running (there were some exceptions) but very random throughout the day.

This HR sensor is a failure and it's probably not going to be fixed by software.

I have my F6x sapphire since october 2019. Since then i used it for hiking, walking and ski touring. My OHR was useless. Max hr was 120 (it should be 160), average 104 (it should around 150) so like I sad, useless. Now in spring I went out with my MTB and it looks like it is working pretty much OK. I have no idea whats the deal, but it seems to be working OK on a bike and nowhere else... go figure 

Sorry if this has been covered before, but I have noticed (and I think read somewhere recently) that the heart rate calculation varies according to activity.

I did a couple of experiments of Fenix 6 vs Polar Chest strap, where I did jumping jacks to get my heart rate up to 135 and then compared. When set to the hike activity, the Fenix barely changed ( went to about 90), however when set to run activity, it was spot on and matched the polar reading.

I guess there are some rate of change filters in the hike mode that restrict the rate of change of heart rate, i.e the reading will move but very slowly. Either that or the readings are less frequent to conserve battery, however I didn't notice it capture any high heart rates during a 6 mile hike the other day.

I can't find any documentation on this, can anyone point me to some?

Perhaps a possible solution is to make a copy of the run activity, rename it to Hike HRM or something, and then change all the screens to the ones I want during a hike?

I repeated the test a few times and the observations seem consistent.

Hey Ya'll, after some testing, I just went ahead and copied the running activity, and for now, renamed them 'hiking' or whatever. Seems to be much better. The running activity HRM has been pretty good thus far. I recommend just copying the running activity and renaming it. I'm definitely leaning towards it being a software issue since it is better with some activities and piss poor with others (hiking). I bet Garmin can fix this.
