IDENTIFICATION OF CONTROLS

There
are seven
operator features
on
the
1IDB SERIES
2
instrument.
1.
2.
TUNER:
Adjusts the detector for its threshold tone, with just
one
turn.
DISCRIMINATE:
Discriminate control allows you to either cancel the effects of
ground mineralization,
or,
distinguish
between
"junk"
and
"good"
targets.
Rejection of
"junk"
items, such
as
nails, foil, pull tabs, etc.,
is
possible with this
variable control. Testing your detector will help you to identify where different
items
are
rejected.
CAUTION: As
with
any
discriminator
on
the market, when set to reject pull tabs, the
American nickel,
some
gold rings and
some
small gold items
will
also
be
rejected.

for
use
with

level
down for maximum. However,
no
sensitivity
is lost
by
this.
.

Button is
pushed—in
and held when
tuning for
"threshold",
then released for
