Altimeter accuracy cold season

Hi everyone,

I have had my FR745 for about 1 year. Already at the beginning I noticed that the altimeter at the beginning of the unit rose by about 10-15m in addition to or minus the real change in altitude on my running route. I then read somewhere on Garmin that temperature changes affect the altimeter. And of course, you get out of the warm apartment into the cold. That's why I accepted it, even if I thought it was stupid.

But now I have seen with two friends that they don't have this change in altitude at the beginning - despite the cold. One is the Fenix5 plus and one is the FR255S. Now that made me suspicious.

Now I would be interested from you, do your FR745 also have this initial change in height or is it a problem with my FR745?

Greeting Ben

Pretty sure it has nothing to do with it being cold. The forum is filled with posts about elevation on the 745 like this one: https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-745/303816/consistent-single-altitude-drop-during-the-training-sessions/1554626#1554626 Garmin does not seem to care about it...

No, that's a different problem. I also know the other one with the jump in height or depth within a second. what I mean is a continuous change in elevation during the first 1-2km of the run session. and here it is usually only 10-15m. i.e. the time in which the watch cools down to the cold ambient temperature.
