If
the ground
area
in
which you
are
hunting
has
only slight mineralization,
you may
wish to
use
the
Discrimination capabilities
of your detector. Determine the amount
of
discrimination that
you need and then search
the
area.
Remember
that the
detec-
tor will
now
perform
as a

Instrument
and
will
be
affected
by
any

more
mineralized
is
the soil.
