Fenix 6X Pro HR Problems getting unreal

Former Member over 5 years ago

Hi all,

Bought my Garmin Fenix 6x Pro about 3 weeks ago.

Really enjoy everything about it. I do fitness roughly 6 days a week, sometimes 2 sessions a day and I like stats alot.

First two weeks it recorded my HR absolutely fine. Now it just stays at 105 roughly.

I did a run about 8miles doing a very fast pace up hills aswell when i know my HR would be at 190 minimum then should sit around 170 for pace, but yet it just stayed at 105 on the watch!!

I put my friends Fenix 3 on !!!! and it gave me 170!!!

I wore my Chest HR on my old suunto and then it was 170-190 my usual pace.

105 just sitting there maybe jump to 120 now and then is just unacceptable for the price of this watch.

Garmin knows the problem that the sensor brings too low values if one does not start an activity profile, but is nevertheless active. Then the sensor has difficulty registering values above ~ 110bpm. If an activity profile is started, the HF suddenly jumps up into the real area. The problem came into force after FW update in mid-September and has not yet been resolved. If you are affected by the same problem, it is best to contact :

[email protected] .

The problem is known there and will be investigated further.

The ticket number for too low HR outside of an activity profile is: PSC-87166.

Whoever has exactly this problem should be added to this ticket.

He is speaking about HR during activities, I think.

Hi. I have exactly the same problem with my F6x sapphire. Can not get hr readings over 100 during activity...

All the updates did not solve the problem. Local Garmin replaced the watch after two weeks and I have the same problem with the new one...

I am very dissapointed with all that
