Your old-fashioned mechanical magnetic compass is reliable, nearly failsafe backup every navigator needs to insure that if the power fails, the computer crashes, batteries die, the government switches off GPS, lightning strikes, or streams of ions from a solar flare disrupt satellite communications, you will not be lost or stranded. GPS will give an indication of direction, but only if you are under way. The properly compensated magnetic compass is the most reliable source of heading information.

You may want to have an electronic compass as a convenience just as you have a other electronic navigation aids, but you still need a reliable mechanical magnetic compass.
