"This expalins why I sometimes noticed a significant discrepancy between the direction shown by my non-compass GPS and actual direction to waypoint when paddling. I thought GPS calculated the direction using calculated location of the kayak and known location of the waypoint." Alex You must read the manual. Some GPS (Magellan e.g.) gives you a choice between a magnetic compas and a satelitecomputed compas. But the precision of the magnetic measurement is limited, recalibration (easy to do when on land) necessary and battery consumption increases a bit.
