HR reading problem
-
@loopylou72 my experiences with OHR combined with a textile strap are not as good as with a silicone strap.
The reason seems to be, that the silicone strap is flexible - even when tightened - which the textile strap is not. When pushing the tightened watch up the arm it only stays there reliably with the silicone strap. -
@Shrek3k Try the new Velcro loop strap if you can get your hands on it. It’s pretty grabby, yet comfortable. My readings aren’t perfect but definitely improved. I think between the strap and a band to push the watch higher up arm, this should do the trick.
I’m still wondering though why this became a problem about a year ago and wasn’t much of an issue when I first got the watch? Could it actually be some firmware changes last year?..
One shouldn’t have to put on a wardrobe of accessories to get a single sensor working properly.

@Shrek3k OK thanks for that could save me some money! I can use the silicon strap from my old watch but it is white and my new one black!

Today Tábata training
Suunto 7 with Velcro strap in the correct place and good tight and Suunto 9 with polar fc

@jorgefd78
Both are saying you are alive

Here is a comparison I did last weekend on a long run. One S9 with Velcro strap worn above the S7 (silicone on left wrist) on my forearm, one S9 on the right wrist (silicone strap) and the S7 on the left wrist. This was a very steep and technical trail so it is very hard for the watches when running downhill as they can bounce. The S7 only had a little trouble in one spot, and the S9 on my wrist was horrible, the other S9 was great. No strap but I can tell you the strap would like exactly like the S9 worn on my arm. All are OHR.
This shows the S9 OHR is fine, it just does not work well on the wrist for running. The S7 is much better.

@Brad_Olwin way different in my case. I was doing Tabata trainings with quick movements. Next Saturday I will test running
-
I’ll do my first strength training with the S7 today, and I’ll report the results of my HR later.

@isazi replying to myself. Did a similar circuit like the previous week (that time with S9 + chest band), results have a similar trend to last week in for the first 20 minutes, but then I did hangboard training and that’s not great for a OHR on the wrist.
-
Today I could do my first run. Very slow rhythm so the watch didn’t bounce too much. Left wrist S7 with Suunto velcro strap. Right wrist Suunto 9 Baro + Polar OH1
The HR was P E R F E C T
s7 in red/pink color
GPS was worst in S7… but this is an HR thread

@NickK yes 100% agree. I think it might be updates too…
I got my new textile strap and tried it today - no change at all same problem. I actually think it is picking up cadence as you suggest, not heart rate - I tried a few faster, slower paces including fast downhill where heart rate doesn’t go up… So is there a fix for this?
