+Not the Mama! Posted February 13, 2008 Share Posted February 13, 2008 (edited) Are there issues which affect the compass? I am sitting in my office right now trying to run down the rechargeable batteries. My office is in a small barn with a thin slate roof. The battery level is showing 1 bar, I am "seeing" 7 satellites with GPS level of 4 out of 5 bars. The date & time is correct, as is my location. I have just calibrated the compass for a 2nd time & yet it is showing North to be approximately in the East position. Does the UPS get less effective it is has been still for a few hours?

+Cacheoholic Posted February 13, 2008 Share Posted February 13, 2008 Are you holding the unit perfectly level? A 2-axis electronic compass requires you to hold it perfectly horizontal to work. If you are, then is there any metal nearby? Quote Link to comment

Glenn W Posted February 13, 2008 Share Posted February 13, 2008 Given that fluxgate compasses are thrown out of wack by electric fields and metal objects, calibrating one indoors is typically futile. Calibrate it outdoors and see if it is still behaving abnormally. Quote Link to comment
SiliconFiend Posted February 14, 2008 Share Posted February 14, 2008 Someone mentioned the magnets in the Rock-n-Roller and wondered if its magnets affected the compass calibration. If so, that would be a huge blunder on Garmin's part. You could probably try it easily--calibrate the compass and test it out, then move the wheel one notch and test it again. Move the wheel back to the original position and see if it comes back (it may not). Quote Link to comment
+Not the Mama! Posted February 14, 2008 Author Share Posted February 14, 2008 Thanks for the tips. There's metal all over the place in here - 4 computers & monitors, 2 printers etc. I'm also sitting right in front of my monitor. BTW Anyone else noticed that the email reply notification doesn't work too well? Quote Link to comment

Move the wheel back to the original position and see if it comes back (it may not). And then remove the magnet and retest. I agree, that would be a huge blunder if the magnet affects the compass. --Marky Quote Link to comment
+apersson850 Posted February 14, 2008 Share Posted February 14, 2008 The wheel doesn't affect my Colorado, at least. Magnetic objects around it does. Quote Link to comment
