@MKPotts I didn’t use Runanalyze before, thank you for showing me another distraction from my work The problem is definitely caused by static electricity otherwise the belt works very well after almost 4 years! On another run when the HR was bad for the first 30 minutes or so, ZoneSense shows absolutely nothing for that part, which is a fairly correct behaviour I think. And you’re right, Runanalyze shows a very large scatter: [image: 1738755482327-4d1327b1-5aeb-4ac2-91ba-da02419335ca-image.png]

@MKPotts I’m afraid you’re right. I had it on my S9 Peak and now on the Vertical so I assumed it would also be available on the S9 Peak Pro. The manual indeed doesn’t mention it.

@Brad_Olwin : Thanks for the feedback. I’ll contact our local Suunto repair center.

@Mff73 I tried today at the gym with walking mode and it showed normal heart rate. Also cross-training mode worked normally. Gym mode worket well first few minutes and when my heart started beating faster, watch began to show as it was getting slower. When I waited for a moment without doing anything, heart rate started slowly rise. I use the same t-shirt I`ve been usin for three months.

Being able to match a Profile to your Activity for the Barometer & Altimeter measurement would be great. I was available on the SA3Peak. (Below from the Manual) 3.3.2. Matching profile to activity The Altimeter profile should be selected when your outdoor activity involves changes in altitude (e.g. hiking in hilly terrain). The Barometer profile should be selected when your outdoor activity does not involve changes in altitude (e.g. soccer, sailing, canoeing). To get correct readings, you need to match the profile to your activity. You can either let Suunto Ambit3 Peak decide a suitable profile for the activity, or choose a profile yourself. With the 9PP, I am constantly adjusting my altitude and immediately after manually setting it, it adjusts itself, and I havent moved If your sailing, knowing accurate atms. pressure readings is vital, similarly, when trail running, knowing accurate elevation is an important safety factor. Please bring back the Activity Profile

@IceRim The S9P has received many firmware updates as it is older. No one here will know how much longer the S9P will receive updates. Since its release in 2022 the S9P has received 12 firmware updates (not counting the last rollback) so I think that your statement is correct about improving the S9P but how long that will continue we do not know.

@ventresca said in PTE bug ?: I’ve noticed a bug in the PTE calculation on my Suunto 9 peak pro (maybe since the last update?). Sometimes, when I don’t have my heart rate belt on, I turn it off (so the heart rate is not recorded in my activity). The problem is that a 10 km jog well below my maximum pace is always scored with a very high PTE score, often PTE = 5. I’d like to point out that I haven’t modified my parameters (heart rate ranges, maximum frequency, etc.). I’ve logged around 200-300 runs since I got my watch. So with the GPS and the calculation of my speed (which corresponds to my jogging pace) over less than an hour, there’s no reason to have such a high score. I take it this is a bug? Thanks in advance, It seems like a bug indeed. The high PTE score without heart rate data is unusual, especially with consistent speed and pace. Hope it gets fixed soon!

@D-Wolfe I would discharge the battery completely, but that seems to take some time in your case. If that won’t help I would do a hard reset.

@dhameljolette said in Heart rate monitor in the cold: This happens for a entire 3 or 4 hours when doing single lap of 1000 to 1500m of vertical gain. Are you maybe using poles? Sometimes I experienced a sort of cadence locking, therefore wrong HR readings, while training with poles on steep climbs (the watch was properly tightened up above the wrist bone).

In the latest software update for the Race S if you set navigation to ‘off’ it will be remembered between activities

@Mff73 That is correct. While I said the message disappeared in about 5 seconds, I actually did not have the full 5 seconds to read it. For the few messages so far, by the time I raised my wrist, I only got a glimse of the dimming message without my reading glasses on. That I can’t read clearly without reading glasses makes the matter worse. That is why I would like the message to stay until I acknowlege it, so I have time to put on my glasses. I make a note to myself to act quickly the next time a message pops up. So hopefully I shall catch it the next time.

@magbueno Great news! The 2.39.34 software update fixed my problem!

Seem to remember coming across this issue in the past. The info around this back then was: It has to do with privacy settings on the Suunto side, workout has to be either be public or the activity should have been shared via the “share link to activity” option.

Hello, It works perfectly with my Wahoo Tickr fit so probably the magene HR band made an error. Going to work with the wahoo then. Thank you all for the support. Greetings from Belgium

@vincent-mayousse said in Wrong heart rate ohr: So maybe with an OHR on the arm/biceps (like the Polar one), it reduces this effect, as le swing is less pronounced at this level of the arm… right, with a larger strap to wear the watch on the biceps the effect should be eliminated, but the watch itself would be hard to read, an HR belt is definitely the best choice.
