S7 HR terrible whilst cycling!
-
@Graham-Nind so true, it’s like the S7 OHR needs to time realise that the body is warm enough or the blood is flowing enough to start accurately tracking…… This could be fixed with an algorithm change with a firmware update.

@BinoWorld-UK So I took the S7 for a spin today to compare its OHR against what’s known to be a very accurate OHR the Polar Grit X and the results are surprisingly very similar.

The difference between low / high and average were below 1% remarkable.

On the last days I could did various test using my Suunto 7 and on the same time the Garmin HRM Dual on the Tacx indoor trainer. I’m pleasantly surprised because I always I believe that chest straps are better, and on these test I could see that exist a minimal difference, when exist. Almost 90% of the time the Suunto 7 displays exactly the same BPMs than the Garmin HRM Dual, and only few times that have these differeces was 142 vs 145, 150 vs 148, etc, minimals differences that, for me, not have sense to wear a strap when I already use the watch.

@flypg indeed, very impressive tracking from the S7!
It remains a very capable watch at tracking walking, hiking, running. I think cross fit or MTB are the areas where it might struggle to follow the accuracy of a dedicated HR strap. A part for that, it measures the RHR very accurately and provide fantastically accurate body resources. The only shame is that Suunto totally buried this watch and never thought about even adding a virtual pacer or Vo2 Max, or even try to improve its battery life. I guess it’s the lack of partnership with Google Wearos hence why it’s a dead duck!

This is what happens when I run! After about 10 minutes it matches my Polar OH1 fairly closely.
Even if i go for a walk it spikes for the first few minutes. It hit 140 during a gentle stroll today.
