OHR accuracy of owners of Race 2

Tomas5

Hello i am curiouse about OHR accuracy in real world. During activities like walk, hike, ride.

Currently i have Suunto 5. OHR is good for 24/7 monitoring. But other than that is too much unaccurate. It often significant part of excercise overestimate HR a lot. For example while walk to work. It is 40minutes simple walk. My hr is around 100-110 usually but OHR on Suunto 5 1/3rd of time records HR around 160 which is nonsence. This breaks all stats like calories, pte, recovery, fitness age. There are some bright days when it measure quite well but most of the time it looks like this:

Note that everything over 120 bpm is 100% not real. I have quite hairy hands so i understand it can make hard time for ohr sensor. So i would like to hear from you guys how is your experience with this watch. I am thinking little bit about upgrade. But if i spend so much on watch, ohr must be spot on.

And before you say, yes i read manual and tried to wear watch tight enough to prevent movement but not too tight. I even tried too tight, too loose, oposite side of hand, but nothing makes it work accurately with Suunto 5. And yes i know chest strap is best but i have some issues with wearing it so please focus on OHR accuracy of Race 2 in sports modes. Thank you for your feedback.

@Tomas5 hey Tom, did you try to shave little section at your wrist the place where your watch fits best ? Without hair perhaps you will got much better values? Only a little section without hairs? Give it a try!

@GiPFELKiND was thinking about that but never tried

Hi, so my experience is that this is the most accurate suunto sensor, i have tried.
in sports mode, there is (in my case) a pretty consistent pattern, the first 4-5 minutes are not that accurate, it has a hard time recognizing the first minutes HR increase.
But withing 5 minutes, its kinda “locked on” and the very very good. No crazy pikes, or even worse from my previous wathces, no 10 minute lows, in a high intense workout.

Sportsmode used this first week has been.
Ebike commute: approx 10 times. 1 of thoose readings were bad for 6 minutes, otherwise on target
Weight training; 3 times: a little slow to capture the first increase, but from minute 4 on target
Crossfit: 6 times; very high intense, and all interval is recognized from the HR graph, on the second. still a few minutes before it kinda hit the correc zone.

I would compare this as being the secong best OHR ive tried, in front of Epix 2 pro, and just behind Amazfit T-rex3

@Tomas5 I’ve been shaving since the day watches with optical heart rate monitors came out.
And in serious training for a competition - always a heart rate strap for accuracy

@Tomas5 I have been testing this watch for some time. It is the only Suunto that gives me good OHR during running and similar to my Apple Watch Ultra. I am very happy with it and have the titanium version that is quite light. I can show a lot of data if you wish.

Than you all for replies
