          The following air consumption is not making sense on the Nautic S
          Tank 12 L x 197 bar = 2364 bar

          start 197 Bar
          end 43 Bar
          154 Bar x 12L =1848
          2.70 ATM x 44 minutes = 118

          1848L / 118 =15,6L minute

            @Nandodiver This is why I think, the POD does not have anything to do with it, somewhere in the Ventilation and GasTime calculation as seen by @mikenizm something goes crazy, it is corrected after some time but this is a serious issue to be solved asap!!!

              @hhouter the air consumption is definitely a bug (starting new topic about it)

                @Nandodiver Correct, but might also be related to the Ventilation issue…

                  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.

                    @hhouter I had the same issue this morning on my Ocean. Freaked me out a bit. I was 17.5m down, shortly after starting the dive. Interestingly looking at my gas consumption graph in the app, it spiked through the roof momentarily when the Mandatory Gas Time alarm fired. Definitely a bug

                      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

                        So did 2 dives this morning (maximum depth 11m)

                        Nautic - new firmware 2.55.46
                        Nautic S - 2.54.12
                        transmiter on Right Side

                        Air consumption seems to be correct in Nautic & Nautic S

                        1st dive Nautic S had no dropouts or alerts (Left arm)
                        1st dive Nautic no droputs or alerts (right arm)

                        2st dive Nautic S no dropouts or alerts ( right arm)
                        2st dive Nautic no dropouts or alerts (right arm)

                        In more and more convinced the issues some people have are due transmitter bad connection with their computer, and is more noticeable at great depths
