Being somewhat of a "high Tech Luddite", I also prefer my compass to
GPS and would pack it before the GPS. I can almost instantly use the
compass to take a bearing on something to be sure I have cleared a
potential obstacle. Being a trigonometry geek, I just think
navigating with a compass and taking bearings is just elegant.
BTW, also being a caver, GPS doesnt work in caves, compass does.

A GPS really doesn't even work that well in the woods. I have 2 and I
always carry them on vacation (Idaho, Alaska, the Dakotas and Wyoming)
but you have to climb a tree to get enough satellites to establish a
fix. My wife was constantly making fun of me waving these in the air
trying to get 3 satellites.
They do work OK in the desert.


Does anyone have any experience with working the GPS from the centre of
a moving vehicle? Does it need to be near glass to receive signals?

Never from center. Dashboard works great.
