OHR Sensor often good BUT WHY SOMETIMES NOT
-
@CalRun48 i dont had a run, was sitting in car and relax. When i train i only use chest strap
-
I would also buy a watch with no OHR… it is useful for many features I do not really want/need/use and as it would leave space for more battery or less weight. The point is that there’s no alternative in the market today…
-
@Luis-Andés-Olmedo yes cancel OHR or make it work 99% in warm weather. Dont care because I use belt in many cases. My OHR experience with Garmin / Coros is very good. They are ahead with OHR and they feel more robust. But I like Suunto watch most by far.
I would say my S9P is ok for me. Often very good but has to sit tight. And sometimes it is less robust.
I think the new sensor in S9PP and SV is just beginning and will be better over time with software I guess.
-
@suuntastic @Luis-Andés-Olmedo do you think there will come more and better OHR measurement for the 9PP and the Vertical?!
-
@GiPFELKiND No insides. Just my guess. But I think many products improve with software. Would not worry. Suunto watches are fantastic and unmatched!

Exactly the same here. My experience with Garmin and Coros OHR is way better, but I like SUUNTO watch most and do not really care about HR (and when I do, I use the chest band)

Today I noticed the first time with SV that the OHR measurement was obviously not correct. I had a trail run after work and I used the Poles when going upwards, and it was wet because of a little thunderstorm… when using the poles the Heart Rate shown was too low… I expected the heart rate should increase because it was steep and tiring, not decreasing.
Perhaps it was a combination of movement/muscle activity (using the Poles) and much water on the skin die to rainy conditions?
Next time, I will try to wear the wrist strap one point closer…
What do you think? -
@SuperFlo75 usually poles through off ohr
-
@DMytro Ok thanks! I think I will have to use the chest strap in winter for nordic skiing
-
@SuperFlo75 but I don’t know how competition performs in that regard (just mentioned to be objective).
-
@DMytro I will try it
-
No watch has ever really worked for HR for me, I think the Wahoo Elemnt Rival was the most accurate. Both my S9B and Vertical are hopeless, but because I like things to be as accurate as possible I always opt for a chest strap which I would recommend to anybody over using OHR
-
Wearing the watch a step tighter improved the situation during my exercise yesterday!
-
@SuperFlo75 Use a Chest Strap !!! Or buy a GARMIN! The OHR Sensor 5th Generation ist Fucking good!!!
-
@GiPFELKiND yes, I think you are right that Garmin and Coros are way ahead regarding OHR. Little surprised that new watch again has same sensor… But anyway I would not wear a Garmin / Coros Watch because of other issues… And even if Suuntos OHR would be better, I would still wear a belt. Think no serious athlete uses OHR during training, even if they wear Garmin. It is more a amateur wishful thinking if you ask me. I more dream of a Suunto without OHR sensor…

FWIW I had a Garmin Enduro earlier this year, used it for a few months before selling it. Same as my SV, the OHR on it was awful and unusable so I ended up using a chest strap. Plenty of other things which ended up annoying me such as your average pace is only shown in 5 second increments rather than 1 second like Suunto. I’ve also had a Coros Apex, again the OHR was no good; it was also the most cheapest feeling, plasticy watch I’ve ever owned so it didn’t stay with me for long
For me personally the OHR seems to not work on any brand of watch, the only one that got relatively close was a Wahoo Elemnt Rival and even that wasn’t perfect. If you care about the accuracy and reliability of your HR measurements then you need to be using a chest strap

I think it is the correct topic about OHR and the Vertical.
The last two rides with the bike I wore the Vertical on my right wrist. This is the side, where I never had problems with OHR devices, no difference with several watches of all brands. All OHR data are identical with the Polar Verity Sense that I have as backup.
The Vertical was unsteady and often up to 50 bpm over my actual heart rate. I changed the position, tightened the strap, the result was not satisfying.
Today I tested the Vertical on the treadmill, as usual on my right wrist. I started the OHR about 10 minutes before I started the actity, to avoid any troubles. But as you can see in the screenshot 1, the first 2 km of the run, the reading of heart rate went crazy. I changed the position twice and tightened the strap to the max after the first data over 130 bpm in the first minute, but no change. I repeated it again, but it doesn’t change anything within the first two kilometers. Afterwards it was correct until the end, no difference to the data of the Polar Verity Sense. This you can see in screenshot 2 (data of the Verity sense).
I will check it further on and hope that there will be some better reading with the coming update. To repeat it, I never had any issues with OHR on my wrist.

I am not an expert by any means, but there are many things that can cause that. First of all OHR is not perfect and I would use a chest strap - especially for bike riding. In fact I use a chest strap during all activities, even for some basic stuff like walking. It can be for example a cold environment so it takes a while to warm up the sensor / arm. It’s a big watch, which is also not in favour for accurate HR readings. I know this did not help much, just sharing my 2 cents.

@tomasbartko
It’s not a real problem for me, because on the bike there is only the option to use an external sensor, because the watch is mounted on the handle bar. In the kayak too. And on the treadmill I usually mount the watch near the display of the treadmill to have the information about the data in front of me.
But on the wrist the Vertical is not perfect for me compared to other big watches. I tested other big watches without any problems and under equal conditions with very good and stable results. No difference to the backup solution of a Polar Verity Sense.

I though about the reason, why the OHR sensor might have sometime some problems.
- I remembered a Casio GBD-H1000 and that there were sometimes problems with the OHR too. The watch is heavy, 101 gr, and has a strap, which is about 20 to 22 mm in the area of the clasp of the resin strap. The resin strap is hard and inflexible, the watch too heavy for a firm fit on the wrist, there are always small movements of the watch, even if the strap is tightened to the maximum.
- The Garmin Fenix 6X Pro is also heavy watch, 66 gr without strap, the strap is 26 mm and I never had problems with its OHR.
- The Garmin Forerunner 255 is a lightweight watch, 31 gr without strap, the strap is 22 mm and I never had problems with its OHR.
- It can not be that the kind of OHR sensor is so different, that I have problems with the Casio and the Vertical.
- I do NOT believe that the temperature outdoor is the reason for differences, because the above listed watches are working in these conditions flawlessly.
- I do NOT believe that a OHR sensor needs some minutes to collect correct data.
So the reason must be the ratio between the weight of the watch body and the strap (material, width, ability to fix the watch without movement, but not too tight to impair blood flow). Heavy watch and wide enough strap must be the solution.
I changed the 22 mm strap of the Vertical, which is a heavy watch for me, 74 gr in solar titanium, to a 26 mm strap. Then I would have a comparison to the Garmin Fenix 6X pro.
And I was not surprised today, that during several test activities the OHR was spot on. No crazy readings, no time to warm up, no matter which movement the wrist made. It just worked during running on the treadmill, cycling on rough trails in the afternoon, walking to the bakery in the morning, doing some weight lifting in the evening.
With the 26 mm velcro strap the Vertical was well fitted to the wrist, absolutely no movement on the wrist and the feeling that it was light and not strong tightened to the wrist (the main advantage of the velcro strap).
And of course it is just my solution and nobody should consider this solution as devaluation of Suunto and the Vertical …
