IRON MASKING
To prevent an iron object from "masking" out the signal
of an adjacent good target, use just enough discrimination
to barely reject the iron trash (e�g� small nail, as seen in
Illustration 1)� This will allow you to detect the coin and
nail together (see Illustration 2) and not miss/mask a good
target�
