@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.

@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]

@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.

@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…

@VoiGAS thanks!! I’ll look into it. My hope is to get him thinking about training sessions using RPE first, and HR as secondary feedback. So this might be the way I go.

Among other things, my watch Vertical 2 keeps restarting in the shower, even when the screen is locked. I think this started happening after the latest firmware update. Before that, I always took a shower with the watch after working out at the gym and never noticed any restarts. Now it happens every single time. I tested this at home to confirm. https://streamable.com/o2d0i3

@bbx100 Same issue here (vertical 2)! It looks like an old bug that had already been fixed, but somehow it seems to be back again. Also, I’m not completely sure, but it seems that some OTA updates may be installed on the watch without any notification.

@2b2bff it happens the same to me, but I haven’t understand the pattern yet. Sometimes I see only one activity type, sometimes more than one. The only thing I have discovered is that the summary discards always at least one activity, it is never complete.

@colakovitz You just need it for the pairing (initial connection), afterwards not. Eats a lot of battery…

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.

@MarTej_cz thanks, I will try

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.
