I've been trying to locate a concrete property marker for some time now,
without luck, and wanted to see if I was going about it the right way.
According to the survey for my lot, there is supposed to be a concrete
marker at one of the back corners (I have a rather odd shaped 2 acre lot
with 9 sides). Unfortunately this marker is somewhere in the woods, in
an area filled with thick brambles, thorns, vines, etc. I'm trying to
clear out the brush, but want to know where I'm entitled to clear once I
start getting close to the property lines.
Any mistakes or bad assumptions with my above process? Needless to say
I didn't find the concrete marker. Before I try again, I want to make
sure I'm at least doing the calculations correctly, so I'm looking in
the right area. My hope is that with sufficient averaging I can get a
GPS location within 20 or so ft, which will let me find the marker.
Assuming this fails... what's the going rate for hiring a surveyor to
mark my property lines? ;-)

Not sure if this will help, but are you using the correct local grid?
In the UK there's apparently a choice between the international WGS and the
more local Ordnance Survey grids - and they're not the same. I know my
Garmin GPS 12 is using the correct grid because it agrees very closely with
large scale OS maps (surveyor grade digital mapping), but trying to find a
nearby and rare type of official bench mark using an internet provided GPS
reference proved impossible. By chance and when the undergrowth had been
cleared, I stumbled across what I'd been looking for ~ 100m away from where
I'd been searching. I'm assuming that the GPS reference I'd been given was
to the wrong datum.- it's an easy mistake.
