Mikes comments are spot on. To me, accuracy is paramount. I always record the number of satellites, accuracy and time with my points. I don't know if my GPS unit will spit them out in a readable file, there is a place for me to type them in a comments field, but it's usually easier to record that info in a field notebook. We use the Delorme PN20/PN40 units mostly because of compatibility with the Delorme Xmap software, a poor mans GIS program that also allows us to download NAIP aerial images and overlay them on 7.5 minute topos.

>> If the unit says that the accuracy is 20 m, but over a long period at
>> the same point (or repeatedly moving away and coming back to it), it
>> only fluctuates by 3 m, does that mean the accuracy is really 3 m?
