HR readings uphill vs downhill with running poles

Hello fellas,

Reporting some strange behaviour of my unit and hopefully will get some advise from you.

I have F6X Pro for almost 2 months and do often uphill/donwhill hike/run in the mountain close by. HR readings (from build in HR sensor) on the way up are rediculous - always lower than 100 BPM, while I`m pushing pretty hard and from experiece (F3 with HR strap) I could tell it should be around 150-160 BPM (and often higher). The strange thing is when I turn back and run on the way down HR readings look decent and close to reality.

Between up and down I usually pause for a few minutes. I`m using running poles on the way up, going down I hold them in one hand. I don`t adjust watch strap and have it tight under wrist bone well away from where wrist bends. I`m using FW 5.00.

Anyone with similar experience/solution? Could it be because of the poles? When I do hill reps on these hills without the poles HR readings looke more accurate.

For reference I`m applying some workouts:

Uphil/Downhill with poles(HR weird): https://connect.garmin.com/modern/activity/4395157819

Hill/reps w/out poles (HR looks ok): https://connect.garmin.com/modern/activity/4333542519

I had a similar problem. Running uphill HR buy far to low, running downhill by far to high. Updated the softwar today with the newest beta and now it seems to work

You're applying more compression to the hands and wrists on the way up. That will restrict blood flow and cause the OHR to misread. That's been explained time and time again in these forums. See J's comments and also read what Garmin have to say about OHR in their support pages and the user manual.
