Unless one goes high end and acquires a survey grade unit and its accompanying software, DO NOT build a boundary fence based on a GPS unit. I find them accurate to within maybe 3 to 5 yds. Good enough to maybe find a soap box, but not quite up to snuff when trying to relocate a dime.
One might rough in the coordinates after a survey making stakes easier to find but not good enough for absolutely defining a line or running a ditch.
