Golden Mask 4
of the metal detector on highly iron-
contaminated terrains. To attain maximum
recovery speed of Golden Mask 4, set the
“DISC LEVEL”
potentiometer to position
2
and the
“DISC”
switch to
“MULTI TONE”
.
Search Depth for Metal Objects
The detection depth for metal objects
depends on the position of the
“POWER
LEVEL”
potentiometer. For maximum
depth, turn the potentiometer to the right
until you reach the audio threshold.
The detection depth for metal objects
depends on a few factors.
1.
Size of the object
The greater the surface area of the object,
the higher the detection depth!
2. Orientation of the object with respect
to the search coil
Horizontally positioned coins (objects) are
more easily detectable at greater depths!
3. Soil type
The detection depth is reduced in
mineralized soils and, respectively, the
depth is increased in homogeneous sandy
soils.
4. Discrimination level
Each metal detector, regardless of its brand
and model, obtains maximum depth in a
non-discrimination mode (
“ALL METALL”
mode).
The
higher
is
the
metal
discrimination; the lower is the detection
depth. On low mineralized soils the level of
discrimination has the smallest impact on
the detection depth and the parameters are
close to those in
“ALL METALL
” mode.
5. Search coil size
Smaller search coils localize and detect
small metal objects (coins). Larger search
coils (>32 cm) have a greater search depth
and are more suitable for detecting larger
objects.
6. Time
of
the
object
buried
underground
Metal objects which have been buried more
than 5-6 months underground emit a
stronger signal than at the time of being
buried.
7. The experience and the skills of the
operator
8. Charging the batteries
Rechargeable batteries have a life-span of
about 500-600 charge/discharge cycles
before they need replacement. However,
these values are attainable under perfect
laboratory conditions.
The metaldetector is equipped with NiMh
batteries
1000 mAh
. Prior to using the
detector, the batteries must be charged with
the automatic charger included in the set.
The single charge operating time is
minimum 20 hours
(using headphones
significantly extends the operating time).
During operation, the
“Low battery”
indicator will signal when the batteries need
a recharge and you need to stop working.
Plug the charger jack into the
“CHARGE”
socket and connect the device to an electric
network of 220 V. The LED light of the
charger turns red to indicate that there is
electric supply. Charging takes about 4
hours, depending on the discharge level
and capacity of the battery. The LED light
turns green when charging is completed.
You do not need to supervise the charging
process as the charger switches off
automatically and the battery cannot be
damaged regardless of the time spent in
charge mode.
