Bad HR measurement

[Benjamin 0]

Hi Suunto users,

I’m using the 9 peak since more than a year now… I must say that I quite happy with it for running & trail but my user experience is disturbed by the HR sensor. I noticed that it is very accurate when I run on a flat road … But when I change my rythm or when the slope changed I faced measurement instability. Most of the time my real HR rythme slow down but the measurement increase…
Of course I tried to follow Suunto recommandation and the two fingers things on my wrist, but without results.

I run about 50 to 80km a week so I don’t have big wrists… Maybe that’s a clue.

Before the 9 peak I had a low cost Garmin watch, I didn’t had the issue with it. (And the GPS fix was really faster). Of course I still prefer the 9 peak but still, I find the issue really annoying…

Thanks anyway for the wonderful job Suunto I making !

@Benjamin-0 I gave up with watch HR measurements some time ago, I have to say that I own a S9B that is more faulty than the S9P regarding wrist HR. I also have thin wrists so I bought a polar OH1 and I’m really happy with the combo.

It’s a feature, which makes you focus on running itself, not watching your watch every 3seconds.

@zhang965 well, ymmv.

@Benjamin-0 some users, like myself, experience the same. You better use a chest belt, I am afraid this is the only way to get accurate HR data

There’s plenty of discussions about this topic. Basically, ohr works very well for someone and very bad for someone else, with all the shades of grey
