Suunto vertical ascent/ descent totally incorrect

[Eduardo Lacerda]

Any updates to this? any ways to mitigate the issue?

I am interested as well on this topic.
Since several weeks, my Vertical is quite inconsistent with elevation data.
There are a lot of mini variations that I can see using the vertical speed field for exemple.

When going uphill, I see that vertical speed fluctuate from positive to negative.

This leads to wrong elevation data. Often 2-3 times what elevation data should be.

Reading this topic, I still not understand if it is a bug or something going wrong with the watch itself.
You often ask if we have cleaned the baro sensor. How can we do this ?

@v.sacre how old your Vertical is? Could be just a clogged/dirty baro hole, or the sensor that is failing

[v.sacre]

@isazi I bought it directly so a bit more than 2 years old.
I always wear it so possible to it is not super clean but I cannot see anything special in the two holes underneath “suunto” label.
How can we clean this ?

@v.sacre try with some warm (not hot) water, but do not put anything inside the holes. My baro sensor failed when the watch was almost two years old, sent it in for repair and had the sensor replaced. Since then it is working fantastic again

Here is an example during this lunch gravel ride. Dual capture comparing Suunto Vertical (worn under arm sleeves) with Garmin Edge 1040 elevation data.
If global d+/d- is roughly the same, there are some big discrepancies between the two. And regarding the terrain, elevation data of Garmin is more representative.

@v.sacre does not seem terrible. What happens in daily mode, if you set the watch to a certain altitude and do not move for many hours? Does it change?

[v.sacre]

@isazi I didn’t try to log an activity but the widget alti and baro show me not always the correct elevation value indeed. For example, I live at 260m height. Watch show me currently 192m.

[isazi]

@v.sacre okay maybe tonight try to set manually 260 and tomorrow morning check what the value is. If it is wildly inaccurate, try cleaning the sensor and repeat the experiment

[v.sacre]

@isazi For information I did a hard reset of the watch. I log 3 activities until then and it seems to be back to normal, without any elevation overestimating.
Hope it will stay like this until Vertical 2 comes out.
