Suunto Race Heart Rate Accuracy In-Depth Review: A Lot To Unpack, But Yet Pretty Simple 

Dude, thank you! Thank you for being so forthcoming and honest with the review! You're one of the few people i've seen who understand that if the OHR is bad, every other metric that derives from it will also be bad. Just as you said - they should sell this with an external HR sensor, reduce the price point a bit (since every metric that it calculates is based off that OHR sensor) and be careful that in the future, they won't launch such a messy, faulty product. This together with the overcounting of the steps made and poor sleep analysis will lead to a world of incorrect data. It's a pity because the devices themselves are gorgeous (especially the Vertical).

Really effective coverage of the HR sensor/sw issues

I just got mine today but i kinda kept in mind that i would only use a chest strap anyway. But for the people who don't want to do that it might not be a wise choice to buy.

Thx. A question arises spontaneously... Why does a company like Suunto market a product with such a painful HR sensor? Mystery

Thanks for your review. I always use chest strap. I have a Fênix 7 and a forerunner 955 , I'm just interested to know if the inaccuracies of the optical heart rate sensor affect the rest of the features of the watch. Resting HR,HRV , sleep and so on. Because if i affect, beside the build quality and look don't offer nothing worth to buy. It's important the reviewers provide to people who watch their videos that kind of information.

I have watched a few reviews... awesome watch, great pricing...but the HR sensor sucks! What a pity! How come a company like Suunto can't make a more precise sensor?

Might need to wear a polar oh1 on your bicep 24/7 for the analytics lol

I have a feeling they will fix this in software. If they can make it consistent they can use machine earning to fill in the gaps.

Has the OHR improved with updates since this review was done?

I currently only have a Apple Watch 6 and haven’t used a Garmin or Suunto watches or apps. Which watch/ app combo do recommend for being user friendly for gym workouts and navigation for trails? I’m looking at Suunto and Garmin. Thanks

im not a fitness expert nor a workout lover thing so for me hrm is not a big deal.. but my only question is, does the watch can be paired with ios devices, thanks

I wonder if suunto can change the optical sensor algorithm to improve accuracy

Do you know if the software side of this problem will be addressed in next week’s update from Suunto?

Useless watch even with other fancy features just because of this horrible HRM
