Suunto 7 Altitude Issues

[pilleus]

@bulkan said in Suunto 7 Altitude Issues:

s7 and s9b

Do you have a comparison of the absolute altitude between the two watches?

[Bulkan]

@pilleus yes,
66 vs 64,4

Today I did some walking hill repeats with both S9 and S7. Here the results of my comparison:

Ascent and average altitude:

Descent:

Starting altitude:

And then end altitude:

The graph:

S9 was on right wrist, S7 on left.

@eurohiker it’s totally different from your kind of results though, I never get the S7 to overshoot. In this case I believe the S9 figures the starting altitude better, therefore the gap, and being the difference less than 10 meters it’s difficult for the GPS to solve it. Unfortunately I don’t have bigger hills to do tests here

@cedric13 I’m just updating on my Suunto 7 defect.
“I have replaced your device with a replacement unit that will come with a three (3) month service warranty, which applies if the original devices warranty has expired.”

I dropped it off last Monday morning to a non DHL office (didn’t get handed over to DHL until the next day) and Suunto received it on Wednesday. It’s at the DHL office as of this morning (Monday) and will be at my door by tomorrow or wednesday.
Tip: if you have a DHL office most likely it will be a business day or 2 faster (ship/receive) due to less mail sorting/3rd party hand off.

This is Amazon level customer service. I’m extremely happy that it will be here before a big upcoming hiking and ski weekend.
TDLR: Don’t be afraid to send it in if you really think it’s defective. Its completely free and took a week from small town france to finland.

Hello sorry if this is off topic…, I am experiencing following issue with S7. It is measuring somehow Descent an not Ascent …, which is 0 m in the app after the activity… and additionally when data are synchronized to Relive and Strava it shows elevation 0 m in those apps as well…(luckily Strava has some correction function for elevation so I can get some elevation there…). I’m using S7 on right hand. Link to the recent activity https://www.suunto.com/sk-sk/move/mikulasstrelecky/6047bd0e148abc47025d3e17
Could it be bug in the sw or in sensor, or any other idea? Thanks in advance. Regards.

@mikulass guess I’m not alone. Been discussing the same issue here https://forum.suunto.com/topic/6114/totalt-ascent-descent-doesn-t-seem-to-match-elevation-graph/17?_=1615327273466

About half way down the thread I discuss having the same issue with 0m ascent. Happened 2 times so far. Both were hikes.

[isazi]

@mikulass the graph shows that there was clearly ascent. Which version of the app are you using? This does not happen to me but now there are multiple users showing this behavior.

[Aleksander H]

@isazi I’m running 4.371 on Android. That said, I have an activity which synced with quantified-self as far back as 31 january with this issue https://quantified-self.io/user/DUrrVK0qMVZO5TtAP0r6Ox2HVLD2/event/48100bfe1ddfeee6242d124cc67d4cbbff0fc13357bac4207d10f0b9d3bfb895

[isazi]

@aleksander-h now that I think about it, is the ascent 0 also on the watch right?

[Aleksander H]

@isazi For the activity with 0m ascent, the watch shows no info about ascent in the diary. Only the elevation graph and descent. I guess, because the number is 0, it is assuming that there is no point showing it.

[isazi]

@aleksander-h I think that’s what the S series does, do not show the profile if ascent is 0 (or something like that). Anyway, this means this is a problem of the watch, not the app

[Aleksander H]

@isazi And a reset isn’t going to fix it, as I’ve already done that once due to getting a new phone :(.

[Aleksander H]

@mikulass Discussion regarding the 0m ascent issue got split a bit, but see the latest posts in this topic https://forum.suunto.com/topic/6114/totalt-ascent-descent-doesn-t-seem-to-match-elevation-graph/35?_=1615371423779

@dimitrios-kanellopoulos hello, i have the same problem with suunto 7 (bad altitude 90% of the time). If i leave S7 on the table in sport mode “run”, at the end it says i made ascent and descent, even if it never moved. it means the same thing? that the sensor is not working? i tried to wash it, to soak it and so on…but always the same problem

[Aleksander H]

@zaimora do you have an elevation graph to show how much it moved?

[ZaimoRa]

@aleksander-h https://www.suunto.com/move/simor160/null
it was only for 11 minutes. but otherwise when doing real activities it says around the double of the real ascent. suunto costumer service told me to send it back but i want to test it still a bit in order to be sure

[isazi]

@zaimora your link does not work (the “null” should be the ID of your activity). Anyway maybe testing inside can cause problems with altitude because of very bad GPS reception. Try also to leave your watch outside with clear sky view. Not saying you will not see the problem, but it is a better test.
