Are any of these good with true heart rate? I use the fenix 6, coming from the 5. On some bike rides I’d be going up a hill and my heart is beating out of my chest and it says my hr is 85 (that was on the 5). Same thing with playing hockey, will come off a shift absolutely exhausted, hr 90. Is there something with maybe sweat that’s not giving an accurate reading? I was hoping the 6 would have been improved, but same issues

I think mine is pretty accurate. I don't have anything else to compare it to, but I'd say it's at least consistent with its readings over time.

I just know when I can barely breath and it’s higher then it says haha. However, on the stair master it seems to be consistent to where I think it should be reading

They are ok. Not as good as a chest monitor or medical hook up though.

Mine is accurate unless my wrist is bent back. That screws with it a LOT. I know it makes a huge difference depending on how tight I have it. If it's really snug then it will say my HR is 52 when it's over 140.

A lot of wrist heart rate sensors can get "cadence lock" where the HR reported is your running or cycling cadence. For me if the watch is tighter and above the wrist bone, this happens less, but I use a chest strap for running and cycling now. (I also have a fenix 6)

Which hr strap do you use?

Garmin HRM-Dual, though if I were buying a new one I might go for the HRM Pro because it gives you some additional cool running dynamics stuff (how much are you bouncing up and down, how long are you in contact with the ground, etc)

Interesting, I’m not a runner and would probably only use it for hockey and cycling (wrist sensor is fine for the other activities)

I have a fenix 6 and it’s been a long time since I tested it but it always came up good. I would look when I checked my BP or I’d use those grips on the treadmill machine. Which probably suck but they always matched so maybe not

They are allright, wrist and chest strap are quite near, wrist hrm takes a few seconds longer to follow HR changes compared to chest HRM.

But!

Wrist HRM are not that good for using on cycling because hand when grips and flexes around will make wrist HRM logic off balance while chest HRM will do job without problem. Add into that dust and sweat and you have slow reading and strange numbers you are experiencing.

So for all kinds of cycing , chest HRM is better choice for accurate readout.

Have Edge for cycling (road, mountain, climb) and exclusively wear chest HRM, but for everything else I use Instinct2 with wrist HRM.

Good point about the wrist movements, maybe that explains it for hockey
