    @Egika said: @Nandodiver you can ask whatever you want. Still please be awayre, that this is a user forum, not official Suunto support. While many users here do have quite some knowledge and can answer many questions, the user base of Nautic dive computers here is pretty small. The answers you received so far are the common knwoledge (and are factual): I summarize again: activities recorded with two sport watches at the same time: only one will sync. No idea if this applies to Nautics as well. at some point old activities in the log can be overwritten (less likely nowadays since there is big memory in the watches that is used for some years to store activity logs) Again no idea, if and to what extent this applies to Nautic Activities loose their details and will not sync anymore after an update of the watch firmware. I hope that there is someone who has more detailed knowledge about the specific questions you asked. But I think they are too special for the users here. Why not give the option to end user to select their Depth Sample rate intervals to 1second ??? This is only a matter of Firmware upgrade on Suunto Side… If they can put 1s depth sample intervals on freedive mode, im sure will work in scuba option… Difference from 10s to 1s depth sample intervals Draws more battery (its a diving watch, Nautic uses 40% battery in 20 dives ) larger data file ( all of them has 32gb internal memory ) Sync will take longer over bluetooth (at least would be accurate sync) store less dives data ( 10s depth sample gets+400 dives, 1s get 40 dives) In the end of the day its an end user option, but at least would solve this mismatch data of air consumption between Dive computers and unable to sync dives…

    Hello, I confirm having the same Surface time bug on my Suunto Nautic on the firmware 2.55.46 when shutting down the device between dives. When you start the Suunto Nautic, the system time will be the time of when you shut it down previously until it sync with the mobile app. And when time is updated, around 50% of the time, surface time will not being updated.

    @EtienneR33 I agree with these ideas but if you want the map to be oriented according to the compass, you need to define the north on your map.

    @Robbin053 Do all straps include spring bars in the package? This could be a problem if you lack a spare. I also couldn’t find Suunto offering them separately.

    @VoiGAS Correct, I use 45/95. Just tried custom and a lot is possible, but for me (Low) 45/95 fits best. [image: 1792231425698-conservatism.webp] [image: 1792251131399-20261017_144044.jpg]

    @sagit Hi suppose at 25m dive to get 14m of deco on air your dive lasted 50 minutes including the descend… With normal SAC of 20L/m you had to use twinset or sidemount tanks of 12L/200 With low SAC of 15L/m the 12L/300 bars is enough but violated the rule of third in technical diving Are you sure you didn’t made some confusion with TTS number, because does 70 minutes deco are irrealistic. Ive ask AI how much bottom time, would need be needed to get deco of 70 minutes on Suunto using GF 45/95 **To force the Suunto Nautic algorithm to generate this specific requirement, your bottom time must be extended to an incredible 180 minutes (3 hours). The exact calculation of the Total Dive Time (TDT) and the chronological profile result in the following values: Total Dive Time (TDT) Timeline BreakdownBottom Time (including descent): 180 minutes Ascent Travel Time (to first stop at 9m/min): 2 minutes Mandatory Decompression Stops: 70 minutes Final Ascent to Surface (from 3m): 0.5 minutes TDT =180min +2min + 70min + 0.5min = 252.5minutes Your Total Dive Time will be 4 hours, 12 minutes, and 30 seconds.**

    @pavel.samokha sure. The suunto variant was created a couple of months ago as well: https://takken.io/tools/suunto-to-ssi-dive-log-helper
