Have a GPS but dont find it that helpful as the little arrow seems to spin randomly in the woods.
Nothing will motivate you to never let it happen again - like getting really lost in the dark on a cloudy night!
If your direction arrow is flipping around randomly on your GPS, you probably need to recalibrate the electronic compass. (Check to see if there’s a software setting to initiate the compass calibration).
I have had my GPS’s electronic compass lose calibration on me on occasion. Realizing that the calibration is off when you’re in unfamiliar territory in the dark isn’t fun, but you should always have a good compass for a secondary reference.
When I bought my last GPS, I went with the Garmin Etrex 22X model partly because it doesn’t have an electronic compass. It can’t lose calibration and mislead me. It still has the little direction arrow but that arrow always correctly indicates the direction that you’re heading as you are moving (based on how your position is changing). So after you select a track to follow or a waypoint to go to, the little arrow will let you see if you’re headed in the correct direction as you walk, and you can correct your course as you go. I find it far less problematic than using a model with a built-in electronic compass.
When I used a GPS model that had an electronic compass, I would do the same as
@boyne bowhunter - I used terrain/topo features to help orient if I could. I used the GPS to see where I was and got the bearing needed to head to my destination. I then double-checked the GPS’s compass using a separate (magnetic) compass as a secondary reference. If the GPS’s electronic compass and the magnetic compass weren’t aligned, the magnetic compass was given precedence for directional reference.
If you don’t have a high quality, name brand magnetic compass, you should get one and take it with you every time you head into unfamiliar woods.
Finally, keep it away from any strong magnetic fields and away from other magnets to minimize the chance that the needle reverses polarity. Like
@Weldabeast, I’ve had a compass needle reverse polarity on me when I carried it in a pocket that had magnetic closures.
