Personally I always thought a GPS was useful for nothing more than instant "re-section" using a map, or maybe following a bread-crumb trail back to camp in the dark but I learned to read a map extremely well on the taxpayer's dime.
Having said that, a unit with a screen and that BLM/landowner software could be quite useful, for sure. But for other than that, I don't see it as being useful to me.
