    Just an update to my earlier issue posted here on 12 Sep, about the excessive ascent/descent values recorded - the watch was sent to service center and within a month I received a new unit. Credit to Suunto service for that. After received the replacement, I updated its firmware to the latest and did some more testing. Yes, the problem is gone, ascent/descent are within acceptable ranges (minute fluctuations still observed), although unlike the S9B or SSWHRB which would consistently be showing 0 ascent/descent on flat terrains, or indoors.

      I did not find anything similar posted here to the observation I made when looking at my wifes activity with her S7.
      She went skitouring and started at 918m of altitude.
      The watch shows lowest point at 870m. The highest point is 1’580m and the watch shows 1’581m 👍
      What surprises me is that the alti graph starts at 814m and within a very short distance (and hence time) rises steep roughly to the actual start altitude. The end alti is about correct. The total ascent should be around 665m as there is no real downs on the way up.
      The total recorded ascent is 854m.
      So the difference of start alti is about 100m wrong while the lowermost point is only shown in the graph and hence differs from the values shown in the overview.
      The total ascent is about 190m wrong… did somebody else have similar experience?

      EDIT: the descent shows correct 651m. That’s about correct. Start and end point was the same at the parkinglot.

        @TELE-HO so something like fusedalti or equivalent not working totally right?

          @isazi the question is how the Suunto wear app does calibrate the altitude at the starting point?

          In other apps this can be done manually.

            yes, I assumed S7 has the same fusedalti as S9B?
            …my wife decided for the S7 without my approval while I was in a never ending meeting 😉 I absolutely agree that this is a great watch, but now I am obliged somehow to learn two different worlds 😂

              @TELE-HO well I don’t know how the calibration on the S7 works, but there must be some calibration because it gets good results without manual intervention. What I see is that the S7 is young, and it is improving in features and precision with each update.

                Let’s see if this was a warm-up issue.

                This should not happen and yes s7 has the same fused alti.

                However, not the same gps chip. It can well be that it calibrated wrongly (100+m???) The initial altitude and due to the correction (as seen) this was counted as ascent.

                This is a typical behavior of gps based altitude , chip cold start, etc. Even ambits (without baro) have this and so on.

                I am keeping track of this and reporting it.

                Go on and keep the discussion.

                  fully agree! the peak altitude was to the point!!
                  …I have the impression that the calibration is not overwriting the history?

                    ok, so maybe she started the activity too quick, without letting the satellites to sattle and let fusedalti do its work?
                    we’ll observe this 👍

                      @TELE-HO yes. This can happen after a reboot also.

                      But should not on the s7 as it has a barometer.

                      Not 100% sure to be honest what’s going on. First time I kinda of see this for the s7. But you never know.

                        @dimitrios-kanellopoulos I have the same problem. Today I started a training session and waited 4 minutes. I climbed 40m without moving. Then I finished the training and started a new one, waited 2min and started running. this time there was an acent of 24m on the first flat 200m. On the whole lap then 72m more than with the Ambit 3.

                          Hi, I have Suunto 7 for 3 days. Is there any possibility to calibrate altimeter/barometer as I am used with Ambit 2? I haven’t found this possibility so it seems that it is done only automatically through FusedAlti.

                            I don’t think it is possible at the moment, but some third-party altimeters seem to let you do that.

                              I wonder if the S7 does the same automatic altitude and pressure tracking as other Suunto watches do it.
                              Slow pressure changes are regarded as weather change and quicker changes are regarded as altitude change…

                              Does anyone know how it is handled internally when not in training mode?

                                @egika In my opinion the S7 does not perform any altitude monitoring. I have tested with a third party altimeter, it updates very infrequently and sometimes it seems to me that it does not take the calibration that happens with Suunto rigs. Perfect altitude instead during the activities! (often compared with S9 cheater). Too bad, I too would like an altimeter management as it was for the Ambit series and as it is for S9 … In the end I have always considered Suunto first of all altimeters, to which they added the GPS starting from the series Ambit (which I’ve all had!)

                                    I haven’t noticed any issues with the altitude recorded by my Suunto 7.

                                    For example, today I did a run along a local canal and at a defined point I turned around and came bac along the exact same route.
                                    As expected a canal is pretty flat, and the watch recorded only 3m of altitude change (I ran 8.6km out and back with a total of 17.2km).
                                    The plot of altitude change is also symmetrical, as one would expect.

                                      Maybe misunderstanding:
                                      Luca states that during activity, altitude registration is Suunto state of the art.
                                      Just not when not recording.
                                      And that was my question: S9 has an automatic altitude measurement that I can have on the watch face and that follows weather changes and switches to altitude change when quickly moving uphill or downhill.
                                      How does S7 handle the altitude measurement when not recording an activity?

                                      Cheers!
