Scott, thanks to link. That's by far the best site I've found so far. It does have a forum section that might be able to help us out, at least they're asking some specific field survey questions.
Ron, I've very limited in field survey knowledge, but the way they tried to explained it to me, is that with the Nokia insturment they could save a point form one setup as "pnt-1" and another point, from another setup as "pnt-2" and then recall those points to use to set up a curb return arc. I'm not sure if that explains the problem very well, but so far they haven't been able to find a way to get the Trimble we have to save points in the same way.
