They certainly are the lazy navigators godsend and I always have a compass with me as well... but I am curious about the "can't navigate by them"
Navigation wise, what can't a GPS do that a paper map can?
My GPS's (or should it be GPII) will all do distance, bearing (true, grid, mag), route profile, X track, T.A.E. isn't affected by Mag Deviation and the back track function is very, very handy as well... plus never have to fart around doing a resection.
Flat batteries are a bitch tho![]()
