FW 10.10, Sensor Hub 7.11 and Hiking activity still useless

I too have been annoyed with this for as long as I have the 6x. 2,3 times I used wife’s polar vantage v on my right hand the Garmin on my left and mobile with strap to compare. I even switched wearing them on different hands. As you say when using trail run profile the Ohr is almost to the point across all of the devices. When hiking the vantage v and the strap are same (I was basically running uphill and reached 160 bpm) while the Garmin is just.. well I do not know what to call it since it was showing rate 79 to 99 at the best. This is just ridiculous for a watch that’s almost 3 times more expensive than the vantage.

I tried with or without poles. On left or right hand. Loose or tight. Every time result are the same when i use Hiking activity. Even fitness band for 30$ is more precise. 

I'm also running and i never had any issues with OHR when i run. Running and Trails running activities works great for me. 

That issue is very annoying and spoils impressions from otherwise great watch.

Same issue here with Fenix 6x Saphire and newest firmware. While climbing steep hills the heartrate sits at 100 or even drops dramatically instead of showing the correct value.

Yes. My HR clearly reacts to to climbs, as can be seen on this image using HR strap. This was slow paced hike by my standards, yet HR crests 160.

Here is tough hike in altitude with extreme climb and OHR. There are some random peaks when it goes to almost 150 for a little while, but then it "corrects" back to its usual 120 or so range. Sometimes it seriously drops with climbing.

Maybe all Garmin Fenix users are anomaly and our HR goes down on climbs?

Hi I have the same problem with my new Fenix 6X Pro.. First two trainings (hiking) ended up with totally disaster OHR reading.

After aprox. 40min (maybe earlier but before i did not note) the HR is too low and not appropriate, I checked my pulse manually with marked areas and it was ~140-160 bpm not 90-110 like Fenix showed. Additionally when I noticed that something is wrong I took another Garmin watch (Vivoactive 4s) on the other hand and measure was good and complied with manual measure..

Additionally, I note that daily HR measure with sleep time is totally not imprecise compare with my previous Garmin Forerunner 235 which shows every day HR picks and correct data. Fenix do not recognize correctly daily HR..

I expected something more from top model.. Unfortunately I think about returning Fenix because at this time he does not fulfil basic expectations.

Below included screenshot from activity.

Anyone maybe has some ideas?

I hope you've reported that to Garmin and same applies to everyone having OHR issues with hiking activity. Otherwise nothing will be changed.

I reported similar OHR issues with cross country skiing last february and fix came this summer. Fixing takes time but without reporting issues, we won't get any changes.

I'd encourage everybody to try latest firmware, 11.75, and report back. For the first time in over a year I got OHR from hiking activity that passed at least basic sanity checks. Obviously, more testing is needed, but maybe Garmin finally figured out what they broke.
