Suunto 7 Altitude Issues
-
@isazi Hi, thanks for reply, app version is 2.1.0 (8785) on ios 12.5.1 iPhone 6… and 0m is on Trail Running, Walking or Trekking activities. Also It happened few days ago when I was walking uphill - S7 started to decrease altitude…I was up around 40+ m and on the watch was shown something like -18 m…
-
@mikulass the 0 meters issue will be fixed, from what we read today in the forum, with the next software update.
-
@aleksander-h Hi, thanks pointing the other thread, yes this is my case… and as @ISAZI pointed I see the graph with ascent, but summary “table” shows Ascent 0m …(apologize don’t know how to resize pictures in forum online editor)…
-
@isazi Hi, great thanks for info. It will be mobile app update or S7 sw update?
-
@mikulass I think it’s the S7 update, seems to be a watch issue.
-
@isazi Thanks. And is there any date for this update already confirmed or early estimate? Thanks.
-
@mikulass well. There tends to be about 4 updates a year and last update was second week of January (I think). So hopefully soon-ish.
-
So did a new 1 hours test in a ventilated plastic container on the balcony today (to protect from wind).
Still a bumpy ride for the elevation. At one point it falls 5 meters and then relatively quickly makes a 10 meter jump, followed by a slow recovery down at the end there.
Not really sure what to do now (if anything). Not really sure how stable a result I can reasonably expect from a watch.

@aleksander-h
I would contact support and check with them. -
@aleksander-h I guess the question is how the altimeter works during an exercise given that the 0 meter ascent bug will be fixed in the next update. As you could see from my balcony test, my watch went crazy when I left it on the balcony, but when strapped on my wrist it’s working okay at the moment. And I did buy it to wear it on my wrist and not to leave it on my balcony.
-
@aeroild My main reason for putting it on the balcony in the first place was to check if clothing was causing the issues. When I went snowshoeing I got quite a few false up and downs on the elevation which really added up. Claimed over 900 m ascent which it most certainly wasn’t. I thought maybe my clothing was pumping air into the hole, if that makes sense.
-
@aleksander-h - I know its jumping around a bit, which could be due to temperature / GPS moving when fixing etc, however from what I see there overall variation is approx 20m, and if exlcude original is closer to 10m; is that really an issue? Its not like we are piloting planes etc and its critical the alititude is correct.
I also understand that you have seen much larger variances, but from above there really aren’t any showing, which suggests that it may not be watch.
Would tend to agree with others, that may be best to wait for fix, and then reassess - especially as from above can’t see anything majorly wrong (from my point of view).

Just for fun, a balcony test with old SSU, and QS altitude graph for 25min
With 3m filtering --> 0m ascent = 0m descentBut my SSU moved about 200m horizontally but with house+moutain behind
-
@jamie-bg problem is that on a 4 hour hike, these up-and-downs quickly accumulated to a few hundred meters extra ascent. If the suunto app was able to correct elevation I probably wouldn’t care much, but right now I have activities with ascents so high I feel like I’m 10x fitter than I actually am .
-
@mff73 Tried the same thing a while back with SSU. 48 hrs outside window: 0m ascent/descent (MC) throughout - albeit at the wrong altitude - “28km” horizontally (house, no mountain).
-
@fenr1r I guess I could just take my SSU for long(ish) hikes rather than the S7 in future :p.
Either way, I won’t be doing anything about it until I see how things fare once the 0m bug is patched.
-
@aleksander-h
maybe I missed it or forgot already: during your hike or run, does the total ascent exaggerate already or do you only see it after the hike?
I assume it happens on the go, right?
Because I rely on the ascent to some extend. If this is not correct the ascent rate can’t be right, either. It’s not life threatening, but good to know by the rule of thumb if it’s still 1 or 2 hours to the summit by the values on your screen. -
@fenr1r
how far can my watch go without me -
@freeheeler not really sure. I was intending on checking during my last run. Then I realized the run workout doesn’t have an elevation graph . So I’ll have to check next time.
-
@freeheeler I got an answer to that on another test, full battery to 1%: 37.29km, 3m desc., 69hrs, 55mins (rather than the 140hrs specced for the settings - high sky mask).
Less “Who Am I From My Heatmap” than “What The Hell Is My Watch From Its Rorschach”:
Sorry, OT.
