Suunto vertical ascent/ descent totally incorrect
-
@Mff73 If it works with microphones, maybe it will also be suitable for watches
-
Strange about wind effect : I have used my vertical several times in very windy conditions and never observed such elevation errors.
(I didnāt know where to put this so I put it here : I wanted to notice that SV works awesomely well under clothes/gloves, even in very cold weather with big gloves + 3 layers => thatās a point I wanted to notice. My A3P and my S9b were very poor in this case with elevations errors and GPS accuracy loss).

@Tieutieu Vertical and the previously used 9PP measure point height very accurately. No issues with that.
The problem is with these spikes visible on the chart - sudden, small, but very frequent changes in elevation. -
@maszop I had perfectly understood that issue => never had such behaviour even in very windy conditions
-
@maszop
and the last solution would be also to consider your watch as faulty.
it is not nice, but sometimes it may happen.
years ago i had issues with my spartan ultra, searching for all possible solutions about baro issues and ascent/descent.
RMA one day, and baro sensor was faulty : new watch never had any issues.
(not related to wind though). -
@Mff73 Two watches are faulty?
9PP and Vertical, maybe, but very hard to believe.
Maybe I can test another Vertical very soon. -
Back in the days when I still owned a S9B, altitude was still recorded for windsurfing activities. The altiude graph went all over the place and I ended up with hundereds of meters of ascend and descend values. The graph above looks very clean. Nothing like the graphs I saw when it was influenced by the wind.
Maybe the algorithm changed over the years, but I donāt know if wind is the issue this time. -
@surfboomerang Something has changed because my problems started with 9 Peak Pro. Previously, in the case of Traverse and 9 Baro, despite much lower accuracy, there was no such disaster.

Hi!
I have encountered the same issue. On an extremely windy day, my 9 Peak Pro reported an elevation of 2400m when the hike (validated with my partnerās Garmin) was around 1100m.
This is the first time I have experienced such a disparity, hiking or cycling. -

Just had a hike with a 1000-meter ascend, and my Suunto Vertical logged 1950 meters of altitude gain. It was quite windy, so this might be the reason. What I donāt get is: wind is a problem + covered by clothing is a problem.
How does Suunto expect me to solve this problem if both requirementsāto hide from the wind and not cover with clothingāare conflicting?
Iām disappointed, to say the least. I would rather use GPS-based altitude gain data than the one Suunto provides. This 2x altitude gain is simply not usableāit messes my records and the track that I publish.
There are quite a few posts with a similar problem in this forum. Is Suunto planning to introduce any firmware update that, maybe, will use GPS and barometer data to somehow detect anomaly data?
-
@Archi-Mendel I have reported this to Suunto and provided extensive logs and files. Others have contributed as well. I am confident they are working on some sort of solution. Several sites will correct your data and you can manually change the elevation gain/loss in SA.

I think itās not a real problem the wind or the jacket if the sensor whole is stress free for the vertical specifically. Stress free = no sweat, water, or debris ie dirt etc inside the sensor.

i once submerged the watch into the river while hiking and changed the ancent by 1500Meters. it was exceptional for strava that i āmanagedā such a a fast ascent -descent
