Civilian units used to be restricted by the Feds to no closer than 30
feet (I think that was the limit), restricting the more accurate units
to military use. That was dropped in the late 90's. (Or, maybe it was
simply reduced and the military has even more accurate units? :) )

If you are traveling through unfamiliar territory, a GPS receiver is a
very useful thing to have. It's good enough to find the cemetery but
not quite good enough to find a particular grave.

So the Droid X (and other cellphones) have the SAME accuracy as the
Garmin units, apparently. I guess that should have been my original
question. Some years ago I remember some interpolated among towers,
and that just sounds not very accurate. Apparently, today they are
as accurate as dedicated Garmin devices, as long as they see the
satellites.

With a 15 foot radius of error, it may not be able to place the grave
accurately, but it'll put you close enough to see it.

Yes, with my Garmin, I use it to find out where in the large cemetery
the grave is, and that's close enough for eyes to find the stone.
And multiple graves lie in the proper pattern on a Garmin map, even
if close together. Any small systematic errors are the same for the
same unit and map I suppose. Precision vs. accuracy. I won't go there.

Thanks!
