Golden Mask 4
fig.3
The precise location of the detected metal
is determined by moving the search coil
along two perpendicular axes (Fig. 4).
fig.4
2. 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!
