 The further out you go, the more accurate, and the more expensive
 the approximation will be, but "good enough" for most purposes.
 It's still limited to the bearing display resolution of the GPS, which I've yet
 to see a consumer grade better than 1/2 degree even though most 
 can resolve mush more accurately internally.
