Seems like the old thread got resurrected. My expectations are the same - to get the software more polished. I use map, navigation, and climb guidance features very extensively - every week, sometimes multiple times per week. In my opinion it continues to be a mess. Almost none of this stuff works flawlessly - that is unless you use these features in the most most basic and straightforward way. There is a large number of quirks and bugs, and unfineshed rough edges. I could easily make a list of probably 10-15 issues that I continue to hit on every long run including: The watch not following the navigation route as planned and jumping from one part of the route to another Navigation direction reversing - almost guaranteed at a turn-around. Also often the route is reversed right from the start. Climb guidance switching direction (going right to left), swapping colors (green for uphill), or just plainly not working correctly and showing me on an uphill segment while I and descending Climb guidance zooming working incorrectly or event refusing to zoom Light blue navigation arrows not being visible Off-route notifications when I am not off route and the watch shows me right on top of the route The above is what I could remember in a few minutes, but there are many more issues. If someone at Suunto took a comprehensive look at this area of functionality and made sure it offers a more polished and reliable experience for trail runners, with all features completed and working correctly, this would be the best thing for me to have in the next update. But in the last almost 2 years of owning 3 different Suunto watches I am continuously frustrated by the lack of improvement in these core areas of functionality. The only reason I continue using a Suunto watch is because there are no significantly better alternatives from competitors.

@gorhabb Good work Suunto to make the Nautic even better and provede more features to technical divers. I have updated and will comment on my findings. Still missing; Improved flexibility configurable field options Both pressure and compass in one screen 1/2 Field compass widget Stop clear compass bearing after 1 min Solve Mandatory Gas Time Alarm at start of dive Clear and improve SAC calculation algorithn Improve ascent alarm to allow deflator function without alarm. 8… Others will follow

@André-Faria Excellent interface and features! Ambit2 users!

Here the behaviour was the same Nautic - No dropouts no issues (right arm + transmitter side) Nautic S - dropouts and issues calculating consumption (left arm + opposite transmitter) [image: 1786959131833-captura-de-ecr%C3%A3-2026-08-17-%C3%A0s-10.28.32.png]

@duffman19 So I tried first with a short stretching activity. Delete from SA, log out of SA, login again, resync and it showed the activity again. However. doing so with my long run, seems to not resync although it’s still on the watch (at least showing on the watch. I noticed. Daily HR, steps, resources are all in SA including the activity time. But GPS and activity stats are not. Would be great to ad Fit/json manualy Back into SA. That’s possible? Is it possible json and fit files are deleted if you uninstal SA?? Would be an explanation I can’t find them on my phone anymore.

​Hi everyone, ​I contacted Suunto Support regarding an issue with Heart Rate zone distribution and TSS calculations for activities synced from my Hammerhead Karoo unit. ​Currently, third-party imported activities ignore custom HR zones set on the watch and instead rely on Suunto’s default backend algorithms. As a result, rides synced from my Karoo end up with mismatched HR zones (e.g., shifting Zone 2 efforts into Zone 1), which directly distorts HR-TSS, CTL, and ATL tracking in the Suunto App. ​I strongly request that Suunto allows manual HR zone configuration directly within the Suunto App (or enables synced activities to respect the watch’s custom HR zone settings/LTHR). This would ensure that data imported from head units like Hammerhead is categorized accurately. ​Below is the official response I received from Suunto Support confirming this current limitation: Thank you for contacting Suunto Support and for providing the detailed information. We understand that you are recording cycling activities with your Hammerhead Karoo 3, which are then automatically synced to the Suunto App, and that you have noticed differences in the heart rate zone distribution between the Hammerhead platform and the Suunto App. Regarding imported activities from third-party platforms, the heart rate zone analysis displayed in the Suunto App is calculated based on the settings and algorithms used by Suunto. The HR zones configured on your Suunto Race S watch may not be applied to activities imported from other services, which can result in differences between the original platform and the Suunto App. At the moment, the Suunto App does not support setting independent heart rate zones specifically for imported third-party activities. Therefore, there is currently no setting available to force imported activities to use the HR zone configuration from Hammerhead. We appreciate your feedback regarding this functionality. We will forward your comments to the relevant team as user feedback for future improvements. Thank you again for your understanding and support. Kind regards, Suunto Support Team

I’ve lost somewhere in Lofoten my Openfit Air during my recent trip in Norway (feel free to use them—I’m giving them away ) so today I’ve bought the Spark. The sound seems way better. I still need to test Hi-Res with Android 17, LHDC V5 though

@Łukasz-Szmigiel said: Also, I’m using fused direction, so it behaves in the same way as in the map/navigation. Compass when stationary and GPS while above ~ 2 km/h. It’s a great idea and works great for me when I’m not moving. But the wind direction arrow doesn’t seem to move at all/align with the wind direction no matter how much I rotate my hand/watch while cycling. I’m not sure if this is a bug or what?! I am using the original Race.

Since my latest findings, im starting to get a conclusion based on what I’ve observed (some of you might not be on the same opinion) Nautic - No dropouts > No issues (air consumption or alerts) Nautic - With dropouts > issues air consumption & alerts Nautic S - No dropouts (sidemount ) NO ISSUES watch & transmitter are close by Nautic S - with dropouts (backmount ) ISSUES since the watch is opposite side of transmitter [image: 1786960733625-captura-de-ecr%C3%A3-2026-08-17-%C3%A0s-10.28.32.png] [image: 1786960755202-captura-de-ecr%C3%A3-2026-08-17-%C3%A0s-10.36.56.png]

@Tamás-Tompa, it wasn’t done in past years, I really doubt that they’ll do something now.

@duffman19 Thank you, curiously, the navigation still worked exactly. But it makes sense what you explain. Thank you

I’ve noticed that significant battery drain is caused by the 24/7 heart rate monitoring mode. Previously, the watch would measure heart rate every 3 to 5 minutes; however, after the software update, it monitors continuously—24/7—without any breaks unless you take the watch off your wrist.
