Inaccurate Wrist HR, What Features Won't Work?

Hey All,

I have very thin/bony wrists.  When I dorsiflex, they go concave.  It's been a known issue for me with various wrist HR products that when I'm active the accuracy of wrist HR sucks.  I've tried moving it up my arm, but it's unreliable.

Correct me if I'm wrong here, but give this, most of the advanced features by first beat that rely on HR (training effect, body battery, stress, etc) won't be reliable unless, of course, I'm using a chest strap during activities.

I'm just trying to figure out what I can and can't really on for data.

    Everything that is activity related will work, provided as you say you use an external HRM. So VO2max estimate, training effect, recovery adviser, and training load will all work.

    What won't work reliably is anything that relies on 24h heart rate monitoring (stress, body battery, (advanced) sleep tracking and resting HR). You might also have trouble with Garmin Pay as that has a on/off wrist detection mechanism that relies on the WHR, but that might just mean you have to re-enter your pin every time you want to use it. PulseOX is likely to be unreliable as well, but as that is a bit of a battery muncher it is not overly useful anyway unless you are at altitude.
