Altimeter

blenedfly Try starting an activity and leave the watch on the same spot for e.g. 30 minutes. If the altitude goes up and down more than a few meters there is something wrong.
You can also strap the watch e.g. to the top of a backpack and make sure that it hangs freely and open. Then take a little walk on a flat surface. If the altitude goes up and down more than a few meters there is something wrong.I’ll try’…
however, manual calibration would take -
@blenedfly no manual calibration will not be the solution here, because the problem is the spikes, not the initial altitude. And your S7 calibrates automatically.

@blenedfly Hello friends,
today the second Suunto 7 arrived, immediately tried but the altimeter shows me an incorrect altitude (it seems to have no variations), or this model has some basic problems or Suunto does not want me as a customer

@blenedfly
I understand you wait some time after the green arrow is constant. we can exclude a wrong operation I guess.
Is it possible for you to upload some of your recorded activities to quantified-self.io, make them public and share the link here?
if you are concerned about privacy you can also send the link in private message. -
@blenedfly I have a large number of activities, tens to hundreds with the S7 and another Suunto (S9baro or S9Peak) all worn at the same time. The altimeter for me on the S7 has been excellent, I can show you some of the data if you wish. If @freeheeler cannot help you I will try. I still have an use my S7 without issues.

I can only check activities like running together with my wife, as she has an S7 in use, without alti issues.
the only issue she’s ever had with her S7 was wrong altitude when ahe started an activity before satellites were properly locked -

@blenedfly
to me this graph looks like the sensor holes have been covered, maybe on sweaty skin.
but it could be a faulty sensor, too. but my bet is, sensor hole covering. on the map it looks like this region is very flat.
let’s see what @Brad_Olwin thinks about it.
-
@freeheeler with the gps the height marks it correctly, the hole seems open to me …

@blenedfly
I know what you mean… but…
open:
close: (common position on the handlebar)

@freeheeler
I understand … I think I’ll give up suunto … the barometer even if I’m not wearing the watch shows -50 …
I bought 2 and they both have the same problem -
@blenedfly
I wouldn’t give up so soon if you like the watch in general.
the altitude is corrected by GPS frequently during an activity. if the last corrected altitude is going wrong again, because of covered holes and hence built artificial pressure (the alti goes doen then), it is likely that you check before it’s corrected again and it shows below sealevel.
It is also visible on the graph. I think no spot in your area is below -100m sealevel.Try a d dummy activity on your balkony, put the watch somewhere for 30min, leave it alone and observe what it is doing.

@freeheeler I’ll try … because I like the watch

On this graphics I not see any strange, this is a speed graph, not altitude graph. This spikes on the speed in MTB sport mode for me are totally normal. At first time I believed that was created by crossing under bridges or tunnerls, but later I discovered that not. I have between 1 or 3 of this spikes on any activity of MTB of more than 1 hour of duration. It’s common come back from a MTB activity at flatlands with max speed between 80-120km/h…
The altimeter have their own topic, sometimes do have strange behaviors that I can’t explain the origin. Nothing of the logic reasons can be applied, but also not bigger differences like yours of 2000 vs 25.
I can’t explain why, but all the these kind of problems happen to me on MTB or Inline Skating. Running or Trail Running no. Also this happen only with the SWA, I tried to replicate in other apps without using SWA without success, that means that hardware it’s OK. The most strange it’s that I practice the sports in similar areas, that means that the enviroments are clear sky, without trees, without building close, etc, and on MTB with SWA I can repeat this spikes or erros, but on Running this did not happen. I expect more this kind of errors on Running, because the watch it’s not clearly exposed to the sky, on MTB yes, have a perfect exposition to the sky. About if something is blowing air into the sensors: I don’t know if it’s possible, but on MTB/Cycling the baro sensor could be directly exponsed into the wind, I don’t know if this can cause some problem or it’s directly related to something in this sport mode on the SWA.
Also in the past I had the problem of the bug that the S7 reebots or freeze in mid-activity. I don’t know if Suunto worked on this or push some kind of silient update to the S7 because in the last months did not happen again. Normally this happened each 2 months and now already they passed 4 months without problems
Start the activity before did not help, like wait until I have fixed GPS on SWA. Looking the activities this not happen on the start of the activity, that could sound logic, this spikes or strange shifting in the altitude happens after really long time that the activity is started (more than 30’).
