OHR Sensor often good BUT WHY SOMETIMES NOT
-
OHR sensors are not accurate no matter the watch (Garmin, Suunto, Coros…) but it is true that in SV during the first minutes of each activity it is completely crazy. Before this SV I’ve had Fenix 7 & Fenix 6X - 6 and those OHR are much more precise.
Sometimes I think it would be better not to have an OHR at all.

@Luis-Andés-Olmedo
i think it may never happen, OHR seems default “feature” now, but, i would also really consider a (suunto) watch, without OHR (to benefit from weight reduction, possibly something else in the watch due to more plae to put it, etc…), because, for me, OHR (with Suunto, i never try anything else) it still not reliable enough (at least with my wrists).
Nice to see HR when “needed”/wanted, but if each time one have to know rouhgly which HR to expect, it has no sense
-
@Mff73 I partly agree. Some of the day-to-day features that Suunto replies the OHR on are all pretty crap at the moment. Sleep and Resources are waiting for Suunto’s own implementation above Firstbeat and I am not entirely convinced of the need for 24-7 HR monitoring. For sport purposes, OHR is more a convenience than superiority over chest HR straps. If a watch came to market without OHR with visible weight and aesthetic improvement, I might consider but I understand that the market is not where I am arguing for.

@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.
