My old watch died and bought Xlander as a treat to myself.
We live only 650 meters above sea level but I find everynight my house can move upto 100 meters up or down which concerns me.
If I manually adjust the height then the barometer is about 20 mbar below the reading of my wall mounted barometer.
If I adjust the barometer in the SEA function then the altitude resets to 0 meters.
Also sometimes when I try to adjust these settings it will flash up 'def' and that seems to limit the amount of adjustment.
I have checked the manual twice and can see nothing on def.
Did note though the late warning in the manual about how you could accidentally adjust the calibration when setting units you want measurements in, mbar etc and wondered if I have done this...
Any one else have any similar experiences or can suggest anything?
