@Klaas Can you upload the dives log file (json) to Claude AI and ask Claude the simple question why the algorithm deviation occurred? Can you let us know the response?

I agree with the points above, the app is absolutely useless at this point. There should be a dedicated app for Suunto diving products.

@Ldive It’s a matter of respect for those who bought a Nautic and placed their trust in Suunto. Unfortunately, I shouldn’t have

@hhouter I also lean towards Ocean/Nautic firmware optimizations (pod/watch position is also important). Received back POD from service, still having hard time connecting before dive (previous firmware version worked way better: turn on gas, watch connects and you don’t have to worry again). Now I constantly need to bring back watch close to POD before dive or connection is lost. Underwater looks like transmission is OK, mainly drop outs occur out of water. ps. My suspicion is with this new feature in newest firmware, probably it brought some additional complexity and stability issues: “Possibility to link two tank pods to same gas If two tank pods are linked to same gas, the tank pressure field will show two tank pressures during dive”

let’s wait for the end of the hiking season and maybe the diving computers will move forward

Hi Same for me … I dive in salt water but I rinse the Nautic in fresh water after each dive

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.

Sidemount 2x 11.1 L is also incorrect [image: 1786292268878-s12.png]

@BlackRabbit I do export from sunto app and import to Subsurface. Just use JSON file export. (still waiting for second POD to arrive from distributor but the one I have is there) [image: 1786209427565-zrzut-ekranu-2026-08-8-o-19.16.44.png]

@Migsey The DM5 still exists, it shouldn’t be a big deal to bring a new version with Nautic / cloud support. Then we could see the same dives in both applications. Suunto app for eyecandy and overview, DM5 for details

I have got this answer from Suunto via the Norwegian service centre: HR sensor is not possible to pair yet, but in the next software update it should be possible. The instructions on how to do this were unfortunately left in the manual, even though the feature was not available at launch.

Its possible to use tank pressure with ascent rate… its one click away [image: 1785601298230-whatsapp-image-2026-08-01-at-17.14.43.jpeg]

Thank you suunto developer to include the tide widget

@ccrhenrik This is usual behavior for nearly all smartwatches I know (not only Suunto) that they can pair to only one app connection. You need i.e. to disable bluetooth on the other device (or to unpair it in BT, but then you need to pair again) , then it switches to the app on the second device. This is how I have solved it.

@bhornz all suunto 22mm straps are compatible with the nautic s

Would be interesting if the Nautic S is a valid competitor too. As fa as I know it misses the Big Display, Dual View (Basic Data plus e.g. Compass) and the battery lifetime which are the big pluses of the nautic. For 5 tankpods/gases and Helium I am not sure So not in the same ballpark, right?

Another review. This one from Scubaverse collab Scubaverse Suunto Nautic
