Hiking with GPS and magnetic compass
Curious as to how people use their hiking GPS units with their magnetic compasses. I set the GPS north reference to magnetic north and twist the bearings on the mag compass and don't worry about magnetic variation/declination. I feel that's easier because I don't have to know mag var for each and every place I may go. Does anyone use true north as a GPS reference and either mathematically adjust or set the offset on the mag compass? If so, why and do you feel it's better than my method?
