Enduro 3 altimeter drops issue

Hi, yes. I experienced the similar issue during the 2 hour walk/hike yesterday, but more drastic example. Drop from 117m to -65m. 3-4 times in short period of time. Watch is clean, FW 13.37. This is the first time I experience something like this on E3, but unfortunately did not have many activities.

I cannot upload picture here without uploading somewhere else.

Possibly wind gusts causing a sudden tiny increase of pressure on the sensor. And higher pressure translates into lower elevation. Try protecting the sensor port with a sleeve, on the next ride.

I wouldn't say so. It was a sunny calm day in the drought river canyon. That biggest drop could be from a meter high rock jump maybe, the map position suggests so. Tomorrow I plan a bike ride and the watch will be on a handlebar so I'll see if it is just an isolated case & maybe another walk today also.

It could be also moisture (i.e. sweat) getting into the pressure sensor port, and when you then bend the wrist, and cover the hole, it shortly increases the pressure on the sensor (causing an elevation drop). Again, protecting it with a sleeve or a sweatband near the sensor port, and/or moving the watch upper on the wrist might help. Worth of trying, at least.

It wasn't really windy, only light breeze, and I wasn't sweaty or wet. What is strange is that same profile on descent is OK (same route up/down), considering speed was much higher (so was the air force getting into baromter holes).
