What happened here? Wrong elevation figures
-
I know the cause. I had a cold bath (just sitting) in the river. And the watch added several hundred more meters for each immersion of the watch in the water. Is it so to add the corresponding muscle stress of cold mountain river water XD?
Here is the pic and an attached GPX file for you to check. It would be nice to understand why it happened. It is an effect of the cold water, for sure. Real numbers are about 750 meters of descent.

@Efejota its not because of the cold water. Its because of the pressure on the baro Sensor when put the watch in water…
But you can correct the values manualy
-
@GiPFELKiND I thought of that too, but I simply sat with the water up to my chest. The watch should have submerged 40 cms the most, probably less. Is it possible to have such a strong effect?
-
@Efejota That will have an impact on the barometer sensor. The water column will put quite a bit of pressure on the sensor and will result in substantial elevation difference.
-
What should be done in such cases to avoid overestimation of these heights? pause the watch?
-
@Todd-Danielczyk Very interesting. I did not think it might impact so much. I guess that the solution is to take off the watch before getting into the water. Thanks for the info.

@Sergei-Ladeishchikov pausing stops the recording, so that works. The watch needs some time to dry after
-
@Efejota Alternatively do a multisport and change to swim. I did this in a mountain lake once and had 8000m of elevation gain added from jumping in and going about a meter deep.
-
@Brad_Olwin In this case I would have needed a new sport called “Cold bathtubbing” or something similar XD
