Okay that's probably a little harsh, but hear me out... I am just feeling very disappointed with this experience...
I've been an Apple Watch 4 user for quite some time and have been extremely happy with the function and reliability but I thought you know what, I want to get a more serious fitness device since I am getting well, more serious about fitness.
Without getting too much into other Garmin issues like poorly designed and un-intuitive user interfaces, poorly designed and buggy Garmin Connect app, and poor Garmin warranty support (because my F6X is purchased privately even though it was a brand new boxed item - I'm not covered under warranty apparently - sounds like a great way to make excuses to avoid fixing issues with your product as a manufacturer though).
OHR on the F6X is poor. I've been testing it side by side with my Apple Watch S4 for the past 48 hours, and cross referencing with manual HR readings to get a view of which watch has been closer to accurate, and the Apple Watch is far superior in every way when it comes to HR readings, especially in the area of responsiveness. Here are a few examples I've experienced most recently:
- Hiking up a steep incline for about 20 minutes, heart is beating fast and I am panting. AW reporting 146bpm, Garmin reporting 109bpm and sticks there for the entire incline, manual reading was 140bpm at the time.
- The rest of the hike the Garmin was hovering around 90-105bpm when the Apple Watch is ramping up and down according to peaks and troughs.
- Running today things started off really well, Garmin was displaying what AW was displaying, but then halfway though my 10KM run it seems to get stuck at 140bpm while my AW is showing 160bpm. I think hmm maybe my heart just isn't beating that fast and the AW is wrong. Nope! I started pushing myself for a period of 30 seconds and AW hit 174bpm while the Garmin just remained at 140-145bpm. I literally could not believe it.
Here's some photo proof from my Hike the other day. The difference in time/distance on the Garmin was due to me switching from Hike mode to Walk mode to see if the HR would improve (if issue was isolated to Hike app):
Now, I am disappointed for many reasons. 1 - because I really do like this watch and it has a lot of fitness focused features, and 2. because I feel like I am totally being ripped off here, paying so much for an expensive device like a CHUMP, and Garmin cannot even get a simple fundamental feature right which lays the foundations for all the other derived data!
And you know what else? I honestly think most Garmin users don't know any better, many just seem to accept the fact their OHR is useless and turn toward other sensors always touting the same version of the same line "oh but OHR can never be good so I would never use it anyway". Yes, I know OHR is not ever going to be 100% accurate, but guess what? Apple Watch S4 and above is seriously close to it. Don't believe me? Check out DC Rainmakers Review on the AW S4 and read the HR accuracy section:
When you are spending this much of your hard earned cash, you shouldn't be accepting this kind of stuff guys! I don't really know what I expect out of this post but I guess I am just really disgruntled and super disappointed in Garmin. Maybe someone from the team will read and this stuff will finally get through - I am not the only one.
If you want to check out some other information detailing the inaccuracies of the HR sensor of this watch, see this:
- https://www.youtube.com/watch?v=DQj1xX77l90&t=37s - Guy on YouTube has issue with HR predominantly in the Hike app. Garmin knows about this since near launch and still to this day has NOT fixed the issue. The device has been out for almost a year now. He details the issue and has an update on what has happened so far.
- https://www.youtube.com/watch?v=itScQILQYlo&feature=youtu.be - here's a poor guy who had the issue really bad, although I believe he claimed in Garmin forums they have been fixed.

- https://www.reddit.com/r/GarminFenix/comments/firnw5/garmin_fenix_6s_vs_scosche_rhythm24/ - this person on Reddit found that when using the 'Cardio' app the HR sensor is much more accurate. Interestingly this is exactly what is mentioned by the person in the first youtube link above. Something is definitely going wrong here, and Garmin are aware of it, they just don't know how to fix it!!!!!!!!
Garmin please get it together. Please! I don't want to have to get rid of this watch, but I can't justify spending $1600 on a device that can't do one of the most fundamental capabilities at least consistently if not accurately.
