[pct-l] GPS, is it worth it?

I agree that knowledge of map and compass use is a necessity, but I'm still 
convinced that a small, lightweight GPS unit is worth it. I just returned 
from a weekend jaunt through Anza-Borrego with 20 students in tow. I was 
surprised to learn what scanr knowledge people have about the use of the GPS 
and importantly, what to do with the data it displays-- especially in regard 
to route-finding and establishing position. The purchase of only a GPS is 
not an immediate fix for route-finding problems, since it is necessary to 
know the coordinates of the trail at all locations. This will take some 
preparation and learning how the instrument works and how to translate your 
GPS position onto a map. So, in addition to the GPS, you need the 
coordinated trace of the trail along with a good map set and you need to 
know how to locate your position on a map with a GPS. This can take just as 
much prep time as learning how to triangulate your position using a compass 
and known landmarks. In the end, I think the learning curves have similar 
elevation profiles (sorry for the embedded pun), but the GPS is much, much 
more accurate, especially if you're just getting started with map and 
compass skills.
