Feh, GPS: False Security for the Navigationally Challenged
I hated the PLGR they issued in the Army...half the time the damned thing would lock up if there was a tree within 50 feet.
'Direction: North (12.3°)'
<Turn around, walk 10 feet.>
'Direction: North (11.2°)'
<Turn left, walk 30 feet> '
Direction: North (15.7°)'
<Curse, turn off PLGR, open compass, shoot azimuth>.
I believe there may still be a lightly-used PLGR somewhere in the Mojave desert courtesy of Top winging it out the window after it locked up, again. Oops, FIELD LOSS!
Works great on the open sea, in the open desert, or at 10,000ft, but damned if it works in triple canopy jungle. Hopefully they've improved them since I got out.
The best was some REMF who wrote into the Stars&Stripes (upon her third time failing PLDC) "It's stupid to still require Land Navigation with a compass. We have PLGRs now, we don't need compasses anymore!" Uh-huh. I'll take a 1:50,000 and my "crank the bezel 2 clicks CCW 'cause it's a little wonky" compass any day.
