The precise location of the detected metal
is determined by moving the search coil
along two perpendicular axes
(Fig. 4).

Setting the metaldetector in an
“automatic ground balance” mode
(GB AUTO)
Set the
“GB”
switch to
“AUTO”.
In this mode, the
“GROUND BALANCE”
potentiometer does not work!
This mode is used on strongly mineralized
soils when the detector is unstable in
manual ground balance.
This is a suitable metaldetecting mode for
beginners.
7. Audio Discriminators
Metal discrimination is obtained through two
audio discriminators.
1. Operation of the Audio Discriminator.
Set the
“DISC”
key to position
“AUDIO”
and the
“DISC LEVEL”
potentiometer to
position
2-3
. Setting
“DISC LEVEL”
to a
higher
position
improves
metal
discrimination, but at the expense of the
search depth! If you want to discriminate
most non-ferrous metals on the surface
(modern pollutants), the potentiometer must
be set to a position above
7
.
When a non-ferrous metal is detected (gold,
silver, copper, bronze) the sound is deep-
toned. When detecting a ferrous metal
(iron),
the
sound
is
crackling
and
interrupted.
If the
“DISC LEVEL”
potentiometer is set
to
its
maximum
left
position,
the
metaldetector starts working in “ALL
METALL”
mode
without
metal
discrimination!
2. Operation of the Multi-tone Discriminator.
Set the
“DISC”
key to position
“MULTI
TONE”
and
the
“DISC
LEVEL”
potentiometer to position
2-3
. Setting
“DISC LEVEL”
to a higher position
improves metal discrimination, but at the
expense of the search depth! If you want to
discriminate most non-ferrous metals on the
surface
(modern
pollutants),
the
potentiometer must be set to a position
above
7.
When a non-ferrous metal is detected (gold,
silver, copper, bronze) the tone is high.
When detecting a ferrous metal (iron), the
tone is low.
If the
“DISC LEVEL”
potentiometer is set
to
its
maximum
left
position,
the
metaldetector starts working in “ALL
METAL” mode without metal discrimination!
