Quote:10cm in 300 m
As far as I remember, on average, it's undetectable under a distance of 10km.
Generally (there are exceptions,) archaeological sites are never so large that the surveyor need worry about such things. No harm to think about it though . . .
Try surveying at 1:20 on steep hills with only tapes - it can't be did.
Well it can, but not accurately.
