Mandatory Gas Time Alarm at beginning of the dive
-
During the first 5–10 minutes of a dive, the algorithm calculates your breathing rate. A higher breathing rate or sudden depth changes during descent may temporarily reduce the estimated gas time, which can trigger an alarm before the calculation stabilizes.
Interesting… but that is the issue with the full tank and in descent, this alarm in the beginning of the dive should never pop-up.
I have also submitted them the logs and model / Serial numbers etc… but didn’t hear back from them yet. The alarm in my last dive at 6m was not scary… the one I got at 33 meter was !!! I simply hope that I never get an alarm in the beginning of a dive which is relevant because now treat them all as irrelevant.

@MartinPadiPro I have two buddies who also have a Nautic. This issue was seen by both, but they don’t bother to submit to Suunto. So it is definitively not a standalone problem…
-
@MartinPadiPro Sounds like a bot, all those answers don’t make sense for the described situation. I hope Suunto is taking that case serious, after algorithm lock and depth sensor failures it could be the next fiasco pushing customers to Garmin or Shearwater.
Thats a shame, when I started diving the question was just which Suunto to choose as a dive computer. Everyone had Cobras, Vypers and then Zoops, but it had to be a Suunto -
@VoiGAS On my first dives with the Nautic I was wearing my EON Core on my other arm to compare RGBM vs buhlman. So the first dives and my first Mandatory Gas’s Time Alarm were recorded with two Suunto dive computers on one POD. The Core was flawless and didn’t have any interruptions, but the Nautic gave the error. This is why I think there is a bug in the algorithm calculation of the Nautic.Due to the fact this was my first Mandator Gas Time Alarm, I ascended immediately after the alarm. Both logs were sent to Suunto support. See both logs, below:

@hhouter little bit offtopic, but I am really interested in your experience with the two algorithms. Maybe you like to share them here: https://forum.suunto.com/topic/15559/bühlmann-vs.-rgbm/10
-
@VoiGAS Yes, will respond with my findings there.
-
A question to make things clear. You only get this alarm on the Nautic, not the other air integrated computers? The problem is with the Tank POD not the older transmitter?
-
@ccrhenrik Correct. Two computers connected to same Tank POD. The EON Core does not give me the error, the Nautic does. See screenshots of same dive in post above. The tank pressure graph in both computers are equal and do not indicate any loss of pressure, see screenprints below.
So my conclusion is that it is not a tank pod error or inteference of a flashlight as the EON didn’t give me the error and functioned correctly. There should be a bug in the Nautic as it indicates the 5 Minutes Mandatory gas time alarm with full tank in certain situations in the beginning of the dive.
See both logs;

@hhouter made two dives today.
No gas alarms this time.
Everything went well. -
@MartinPadiPro Yes, but let me guarantee you that you will encounter the same issue soon (if Suunto doesn’t fix the issue in an update). Between my first and second time I had 5 months diving without issues, between second and third, 1 month.
