New here,,,,,,,,,and this place is GREAT!  I'm not to technological but I built 2 houses in the country from top to bottom, hunt, fish, woodwork, can survive in the woods alone forever by myself,,,,,,,,(or with a woman if I have to)...........but I just can't seem to get my GPS to calibrate the compass.  Additionally the weather and altimeter never worked.  L read where you get to the compass menu and do the right/left/right/left thing and enter 22 but all that gets me to is a screen that states I need extended calibration and "Sensor Degauss".  It sits in the Degauss screen for 30 minutes,,,,that's when I get fed up and shut it down.  Any advise?  My next idea is to put it in the crotch of a tree at 100 yards and pull out the 22-250..............Thank you for all the help
