@dreamer_ as I said: As the watch is only 3 years old, it should get updates… On the bright side: the Vertical is unaffected from the newly introduced crashes mid-activity… It only has the old ones…

@2b2bff I agree with you 100%. Beyond that I feel like the initial post was pretty aggressive. We are a community of people who help others better understand their Suuntos. I am not sure if a random rant on this board will attract the attention from the main designers that you are hoping for. I am guessing they have long term strategies and planning that is not dictated by random posts on this forum. Would it not be more productive to come here asking for help or work arounds from people who have been using Suuntos for years? Interesting other info might be that even though Garmin has the feature I have had issues with it slowing down my watch going into a few days of the same activity. Even DC Rainmaker has spoken about how Garmin struggles with such large .fit files as they grow over so many miles.

@André-Faria It is hard to claim warranty for this. The watch restarts randomly. My seller says: the fault did not appear.

@mickywickyftw I don’t see how ZS adds anything that you don’t get with HR anyway. For me it is just too inaccurate. I wanted to know how ZS actually performs and analyzed 150 runs and rides that I all did as Suunto recommends for ZS. While the mean reported thresholds over all workouts come very close to my actual thresholds, the standard deviation is at 9 bpms for the aerobic and at 7 bpm for the anaerobic threshold. So therefore on normal runs or rides, I get fluctuations of up to ±9 and ±6 bpm respectively and I never know when it is accurate or not. I had workouts where ZS told me that I am pushing way too hard but my HR was as usual and I was able to do the workout/race exactly as planned. I also had it the other way around. If I would have listened to ZS, I would have had a lot of destroyed workouts or races. From years of racing and training, I know that my HR never differs more than ±2 bpm at the anaerobic threshold and ±4 at the aerobic threshold if I am not completely destroyed or sick. So therefore HR and pace in combination with RPE is way more reliable. At least for me.

@Goatee Suunto reached out to me via email asking for more information (watch serial number, app version, etc.). I sent them the deets, so I’ll see where things go from there. Hopefully we can isolate the bug and get it fixed.

Since Suunto still shows no meaningful response and reports of Nautic issues keep piling up, I have now reported the Nautic through the European product safety system as a potentially dangerous product. Given the false mandatory gas-time alarms and other incorrect dive data, I think an independent safety review is overdue. I’ll keep you updated.

Looks great in my Suunto 9 peak pro [image: 1786262740019-1000295463.jpg]

@tm3610 said: Any idea if there are rumors of a new Run or smaller, budget variant? IMHO a Run 2 and a Race S successor is to come in the next months. The real question is when…

@Elipsus Ultimately, it doesn’t really matter. According to Suunto’s specifications, the Core 1 watch could be used at depths of up to 10 meters. You can even use the buttons underwater. This has been tested many times without damaging the watch. Whereas, according to these specifications, the Core 2 can be used at depths of up to 2 meters only. So, it’s a hardware downgrade. This was confirmed in an email exchange with Suunto support.

Wow, Dark Mode looks great! Now I can check my Runs in the Night without getting blind

@isazi Yeah, let’s hope they implement it as soon as possible.

@shakra2005 Ja, das geht - jeder Bluetooth Herzfrequenz Sensor funktioniert, also auch z.b. die von Polar und Coros. Deren Oberarmsensoren sind sehr beliebt. Zu Zonesense gibt es eine lange Diskussion. Für mich funktioniert es nicht für andere schon. Deine anaerobe Schwelle kannst Du auch durch Tests abschätzen und dann die Herzfrequenz Zonen danach einstellen

@BokiRun In terms of heart rate, I have no complaints about the RUN. I compared it with a Polar H9 during a vigorous workout, and it was flawless.

@Squirrel Yes, Vertical 2. This was something that I’ve never seen before - the grey Climb Guidance segment. So perhaps a new version of Suunto App is to blame. Edit: in fact I can still repro this by loading the same route: [image: 1786397308951-1000005704.jpg]

@OutdoorMan Yes, but Resume later is requested here a long time and nothing did happen. At least now there is the possibility with Apps and volunteers like Joaqin. Better than nothing for sure

@Steven-Hambleton Well, I guess a sync back to the watch after a trim could be implemented to keep the values in sync. But at the moment everything is better than having a run in your stats with a 30min car drive afterwards or whatever.

If (and so far that is a big IF) a new firmware release will be available for my race is I will be very hesitant to install it, reading all those crash reports after the new race 2/vertical 2 firmware. The bluetooth connection lost to heart rate sensors isn’t fixed anyway, so I might as well stay on the current firmware.

New version pushed with one change to use a median of 3 rule on the acceleration - ignores single-sample spikes and should smooth out the power readings. I’ve also added text in the description to say that so far I only know of 9PP and above watches being able to run it. @phck9b let me know how you get on with your S9B.

@jj-frl Some of Suuntoplus app could be the solution for you question 1. Wheather, timer, sun, moon = sure. Steps, temperature im not sure
