Problem of cumulative elevation gain
-
@silentvoyager
and the question is: will Suunto be able to improve this? -
I’ve just posted about a similar issue. My issue kicked in around the same time as these posts and still we have had no response from Suunto on a fix.

Where did you post it? Did you get any response from Suunto?
If you posted here I see your are getting responses and help. And you had one watch replacement.
Please, let’s write about truth and don’t let the emotions write thing like: still we have had no response from Suunto on a fix.

Mind sharing an altitude graphs? Can you see lots of little spikes? Is the altitude right or wrong?

@isazi
mind merging this topic

you’re not alone, but what you see seems to be a lot!
When the skilled guys here see your alti graph they can make a tendency diagnosis.
Common issues are blocked baro holes, e.g. by rainjacket, tight watch wearing style etc…living sideways

@freeheeler there is no merge button in the forum. If the OP wants we can lock this one and keep discussing in the other one.

ah really? I thought few of us have a magic button to merge similar topics sorry, ignore my comment

@freeheeler I am experiencing some issues with elevation gain in general as well, especially since running with a Stryd footpod.
Issues I am experiencing:- Watch showing way to much elevation gain while Stryd shows more realistic elevation gain (e.g. on really flat course watch says 230m up/down, stryd says 20m up/down and TP elevation correction shows 15m)
- Watch shows 0 elevation gain while Stryd shows more realistic elevation gain on 1min hill intervals (e.g. watch says 0m up/down, stryd says 363m up/down and TP elevation correction shows 262m up/down)
The values in TP before elevation correction are the values from my watch. I am not into a precision of like 1-2m elevation gain however a realistic elevation reading would be very helpful. Could you explain where the baro holes on the watch are, then I can check those. Any other ideas? Could coupling a footpod to the baro cause such a major difference?

No, the pod is not the cause of the issue (I run with it every time).

@daretodream It is possible that the sensor hole is obstructed. Or, if there was high wind and the wind hits the sensor hole this can happen.

@Brad_Olwin
Hi Brad, I experience similar problems very often.
Elevation gain all of the sudden goes wild (tiny spikes)…but this is very random…some of my hiking activities don’t show this issue and some do.
Interesting, when I’m walking a flat surface with no or a little elevation gain I haw never had problems with “spikes”.
And the most interestig is that this “spikes” are visible only on a part of (hiking/walking) excersise…
I think that my watch isn’t to tight round the wristand the wind wasn’t blowing nore the jacket was obstructing sesnsor holes…
Based on my description, Do you think that this is due to dirty sensor? -
@Vrba007
I guess the spikes are pointing downwards. if that is so, they most likely happen due to sealing effect of the baro holes on sweaty skin. a slightly higher pressure is recorded and when the pressure is relieved the alti goes up again, summing up in a higher total ascent value.
I’ve had this happening with my S9B x-alps, too, but rarely after I knew how to wear it to avoid it.problem got solved with S9P’s new sensor position and I appreciate this design is carried onward to S9PP and Vertical

@freeheeler
Yes, I also think that sweat was this time the reason for these problems.
You said that knew how to wear it…what is your “secret”Since, I am lefthanded I wear my S9B watch on my right hand, so the sensor openings are closer to my hand/palm), and the buttons away from it…
do you think that I should change the arm on which I wear my watch? -
@Vrba007 @freeheeler I wear the watch on my left wrist so this could be a potential issue. The other problem I have had is wind. If fairly heavy winds hit the sensor the elevation data will be way off and you will see the spikes.
-
@Brad_Olwin thanks for advice…I’ll test this on my next hike, and see if that solves the problem.

@Vrba007
I used to wear my S9B fairly loose so that the holes are rarely close to my forearm. as @Brad_Olwin says, wind can be a reason, too. this will look differently on the HR graph compared to the sweat “theory”.
wearing the watch on the right wrist is a different story. if you wear it loose the sensor will sit on the back of your hand -

@zhang965 thanks mate
It’s interesting though, how spikes showed on the part of a trail where I know, that I have sweated a lot…
