HR comparison

Today just a walk again with both watches. S9 with smart sensor. Again great difference just walking in not cold weather. OHR not usable. OHR was not direct cadence lock all the time. It was in between cadence and real HR. At the end I stood 2 min and couldn’t believe what a saw. Also with no walking motion big gap. No change within 2 min! See picture after 2min standing. It seems that there is a big overlay or watch is lagging behind and waiting to get another trigger and until then it is just guessing… more and more believe higher intensity maybe better than lower. Also changed watch positions with almost no effect.

Additionally I found this.

„The pulse sensor is also new. Or new by half, because the sensor changes slightly with respect to the previous one (it is now proprietary to Suunto), but the algorithm continues to be that of LifeQ. At least for the time being, because the forecast is that there Suunto will also take over.“

Can this be confirmed? Please Suunto take over

@isazi @Brad_Olwin Sure your pre-release not production versions didn’t have already a draft of new Suuntos own algo?

Brad_Olwin

@mountainChris Not necessarily no improvement but my walking and your walking experiences are very different. Yes, I have walking but not sure a belt to compare to, I would have S9Baro or S9Peak compared to S9PPro

I’ve been getting real bad OHR readings with S9PP over my first two runs thus far. See attached images of two easy runs for me, where real effort has been at HR Z1 mostly.

Circle in yellow is the time it’s been reading close to my effort, you can see OHR real high with wrong reading most of the run, for the second image that big drop is because I took the watch off and put it back on. Also second image is with today’s software update applied.

I have slim wrist but I’m using the watch with the same fit I used S9P which only during cold day runs would’ve given me such bad readings, which is not this case.

I’ll keep trying to find my sweet spot for S9PP OHR I guess

@herlas Interesting, seems to be a difference to S9P from your experience. If you are running cadence 160-180, it also looks like cadence lock. Do you? Such readings I never had with running flat with S9P. Only bad hiking. Soon time for the first S9PP run.

What to think about this one?
TrailRunning session (almost flat), S9PP OHR, compared to SmartSensor linked to Locus on phone.
No tattoos, no that much hairs, not to much tighten.
Checked a few time with fingeronthewrist sensor to be sure,
Still not reliable yet for me. I don’t want to doubt each time.

@Mff73 if I were Suunto I would deactivate OHR for sports as long as it is like this for many of us. To much bad news imo. Also bad timing with Coros next level looking OHR…

@Mff73 Try switching arms if it helps or change watch position above wrist bone. Maybe ohr sensor will be tweaked thru updates.

The Apex2 and 2 pro are also not flawless.

@el2thek I personally think or hope both watches will do good with SW improvements. If you’re Suunto fan, change is no option

@Dušan-Ković I think it was said among comments it was a typo.

@dulko79 I just saw image and noticed S5PP…

Just a small comparison. I usually use Verity Sense as HR monitor for all activities, but today I wanted to try S9PP internal HR monitor. And it works bad…

Some Verity sense examples:

S9PP:

Hr is going allover the place. On Verity Sense you can make out all spikes. It blends individual spikes into single chunks.

@Dušan-Ković
are these direct comparison? it doesn’t look like.

Dušan Ković

@freeheeler Nope, different sessions, but S9PP graph is a lot noisier

Intervals today, as good as usual, under the rain and with colder temperatures even.

Lucky you.

A quick question to everyone with S9PP OHR experience.
I currently own the original S9B with stainless steel bezel and weight of 81g (by specification). The S9B OHR doesn’t work for me for anything other than slow walking. In case of running the HR simply jumps to extremely high and unrealistic values, regardless of how tight the strap is. I knew this buying the watch, so I’ve always used in combination with external HR strap and I’ve been fine with it. I believe the reason for this behavior is the large and top heavy dimensions of the S9B.
But the S9PP with it’s smaller weight and footprint looks like it could solve these issues. My question is - is there a noticeable difference in OHR accuracy between the steel and titanium S9PP models, since this is the only reason I would justify the price premium between the 2 versions?

Egika

@Ivan-Vasilev while you are right about the watch weight as a factor for OHR accuracy, the small difference between steel and titanium does not play a significant role.
All other factors (skin temp, watch position, armband tightness etc) play a way larger role.

@Ivan-Vasilev In my case, the OHR os the S9P is simliar to the S9B and I use it with a HR strap. I have discovered recently, howevere, that results are almost perfect if I wear the watch really tight, so it does not move at all when running. I have been checking recently and it seems to work as expected. But I need to get used to wear it so tight, TBH.
