Suunto 9 OHR readings

[pilleus]

I tested a Suunto 9 and a Spartan Sport WHR Baro for cycling. Both gave me bad OHR values. I used all tips and tricks given from Suunto.

Then I placed the watches on my right arm/wrist and was astonished to have usable values immediately. Not only once, but ongoing.

May be this is worth trying for other people too.

@pilleus this ?

Ah, okay, I didn’t read it before.

Yes, I can confirm this. The same 2 - 3 cm behind the wrist, the same width of the strap, just the other (right) arm.

@pilleus Perhaps we need to make a poll about this ?

For me, with Spartan Sport WHR Baro OHR doesn’t work no matter what I do. I didn’t try yet to jump on my right foot during the full moon spitting behind my left shoulder Usually, I use the chest strap and whenever I forget it or for some reason it won’t connect ( this week I totally forgot that I left the watch in airplane mode and used OHR during cycling accidentally ) the HR I get is rubbish. In my case it’s a lot lower than if should be, almost near my resting HR recording values 50-60bpm during activities like cycling, running or HIIT circuit. Sometimes it elevates 100-130 just to drop down again and in some cases I am not able to re-adjust my watch every few seconds measuring 2 inches from my wrist etc. Considering other devices I have been using, OHR in Suunto is the worst I have experienced so far. If not that I can pair it with the chest strap I would probably switch already to something else.

@jsr184 Same for me. I avoid using OHR as much as possible. But yesterday I had issues with my Polar H10 and had to use OHR for a short warmup on treadmill. OHR was correct in the beginning of the warm-up, but once I picked up the pace it shot up to 185, and then to 200+. I am pretty sure my actual HR at that moment was in upper 150s or lower 160s.

By the way, a bit of off-topic - my Polar H10 HRM fully discharges battery in about 3 months. It has just gone through the second battery in about 6-7 months of usage. Is that only me who has this issue?

Just to give my 2 cents … currently using a Suunto 9 and before a Spartan Sport WHR, and I am usually quote fine with the OHR with both watches.
Usually means: excellent results while cycling, walking, hiking and on a stationary bike, very good results on an elliptical trainer and while doing “street runs” and not too rugged/technical trail runs, really acceptable while doing technical trail runs and … not so good (and I knew it before because of the movement) while rowing and during cross training / weights.

On the left arm/wrist? How strong is the strap fixed? Can you show us the exact position (behind the wrist, 2 cm or 3 cm)?

Thanks for your advice!

Hi all,
Just to avoid misunterstandings, In my case, I had to change the watch to my right wrist because I’m right-handed, if one is left-handed, so left wirst it’s the dominant wrist.

@Dimitrios-Kanellopoulos if you do a poll about this, my sugestion is to use "dominant " and "non-dominant " wrist, to keep it clear

Cheers

Apologies for forgetting to mention these details: left wrist (slightly higher (approx 3 cm) and tighter than usually / during “regular hours” ) … more or less tighter one notch, then pushed up until it “feels good, tight, but comfortable”, and it is my non-dominant side, as I am right-handed (not very scientific )

@Shrek3k thanks, my experience is the same, just on the right arm.

In my opinion it’s a difference between running/walking and cycling. The problems happen during cycling, never during running/walking.

@pilleus I agree that there seems to be or is a difference between cycling and walking/running. But for me it seems to be better when cycling - as long as I avoid cobblestone and give the watch some to “soak” (feels like a waste of time and is rather annoying but seems to be worth the time).

Before voting I for example need to try the other arm which I have not used with / tried for OHR as I have been able to receive acceptable results on my “usual” arm …

This week on the treadmill.
First 3 minutes not accurate then a jump at 206bpm then was I would say accurate.

Well, mine is a Trainer, less expensive than the 9.
But I would say that except some what I would call minors and exceptional issues the ohr readings are usually not that bad.

Trainer gives me better results than the 9. No doubt.

@mountainChris it has been said that cheaper and lighter watches have better ohr because of less wobbling when running (due to less weight)

That is what I understood as major factor, too - the weight (and the following challenge to attach the watch “immobile”), so the better sensor and even algorithm won’t help if the thing is wobbling … nevertheless a little frustrating and obviously one reason why Suunto is not advertising real HR-measuring from the wrist …
