Real world data

@nickk keep in mind one thing when hiking. The blood flow is restricted resulting in typically lower HR from any device. A belt reference is needed. Lifting the hand , letting some blood flow fixes that.
Unfortunately no OHR will ever fix that due to the nature of the human body (I hold my breath to be mistaken)

@nickk regarding the altitude.
The initial altitude of the s9P was 10 meters pretty much wrong. So at this case we check the vertical error (that is typically 5-20m). If the error is higher than the difference it you apply we keep it uncalibrated but slowly letting it adjust (so a kalman filter). If the conditions provide we retrospectively correct.
In your case as you can see we slowly corrected the altitude instead letting it jump to some not correct value that would have cought the users eye, and also would have provided subsequent wrong ascents and descents.
I hope it makes a little sense

@dimitrios-kanellopoulos That’s fine with me. As I said: I don’t think F6X would have done better without a strap, and I know for a fact both COROS and Polar are no better. COROS was a total basket case when I tried its OHR on several hikes.
-
@nickk agree. Same here. I tested coros apex pro for a few and ohr was better than the s9b but worse than the s3 and worse of course than the s9P.

@dimitrios-kanellopoulos I always use a strap for hiking. On my hike today, the altitude measurement was almost perfect. The S9P was only 2m higher at prominent points with official altitude information.

Just tried a first short and easy swim. I have the impression that the GPS is considerably better than my SSU. Total distance is quite spot on. Heart rate is still erratic.

Hiking today, will post a comparison against Polar OH1 if I can!

So first day in the French Alps, I think the Peak’s OHR is working very well for me. Here it’s against a Polar OH1 paired to the baro.
Hiking, no poles.

@isazi looks good. On the next hike I will test it with the hiking poles and see if it works that well.

@isazi
Hey, where are you near in the French Alps? -
@mff73 spending a week mountaineering in the Écrins!

@isazi
Enjoy, nice and perfect massif for this. -
@isazi nice place to hike or trail
Less than 2 hours from my house but i don’t know there very well
-
@isazi How do make this comparison?
-
-
@isazi I’m a user - just not sure about how to go about making the comparison
-
@wakarimasen record the activity with two or more watches, sync them to QS, then select and merge activities
-
@isazi Great stuff - thanks!

just a short comparison an my run today
S9P (violet) is also very good. the Vertix (blue) is a bit smoother and gets some curves a bit better, but this is only in detail.
Here is a tricky part because high rocks surround the steep path (UIAA 1). Coros smoothes it a bit more so it looks a bit better. Therefore the upper violet track is a bit off track but blue makes that “step backwards” below the upper right rock.
I don’t think in this detail you cannot say that anyone is better or worse than the other. Both do a very good job.S9P is above. I would say that S9P got the elevation better today. Average over all my runs up to this summit is 997m.
But again the “zero-values/dropped values” on the S9P. Why is this?
Battery drain:
S9P 11%
Vertix 6%I don’t test oHR as there is no watch that can measure it correctly on my wrist (only on a steady run with little HR-changes). But hiking, intervals, trailrunning especially with poles… no chance for me to get plausible oHR values.
Good job Suunto

@theo-lakerveld woah - that’s a HTFU effort. How often you doing 60 min straight at threshold?
