Ben,
Our basic field methodology is to divide historic sites into 10 x 10
m grid units and then conduct metal detector surveys of each unit.
And we do each unit twice, typically, in north-south and east-west
directions.
Small "hits" for objects like nails are simply quantified in the
field using raw counts per survey units. Actual object recoveries
are pin flagged ... I see no reason to use plastic vs. metal pin
flags ... Your metal detector shouldn't know the difference if its a
least a few feet away ...
We would use a total station to map in the pin flags, but given 10 x
10 m collection units, you should be able to guesstimate your pin
flag locations within those units to a reasonably accurate degree.
Certainly easier than kite photography, and probably more accurate.
