THE DEVICE
The detector consists of: a coil, a
strip /connecting the coil to the
electrical set/, electrical set, armrest
and a battery box.
Searching coil /Coil/
The coil of Golden Mask 1+ is 9
inch DD sized. It’s made of plastic
as in its lower side it is poured on
resin which makes the whole
construction very heavy and air-
proof. The coil is highly sensitive
towards as small and big objects.
Additional coils
Golden Mask 1+ can work with
additional coils DD: 5'', 7'', 8'',9'',
10.5'', 12'', 12.5'',9x10'',10x12'','',
12.5x15''
Smaller sized coils possess better
sensitivity to smaller objects /such
as coins/ and are preferably used in
heavy mineralized and dirty soils
/especially concentric soils/ Bigger
coils /12, 12,5x15) are much
sensitive to bigger objects and are
suitable to be used for searching
deeper buried objects, and possess
10-20% better sensitivity than DD
10,5 inch
Strip
The strip is made of aluminum tube,
as in its lower side it’s made of
carbon in order to not disturb the
work of the coil.
Electrical set box
It is made of plastic of the well
known company BASF and is
extremely strong!
Armrest
It is made of aluminum profiles for
better strength. In its front side is
placed the foam coated handle.
Battery box
It is made of plastic with a slot for
10 batteries NiMH- 1,2V/900mA.
METAL DETECTOR
OPERATORS ETHICS
Please, pay respect to the
personality and property of the
others;
Always ask for permission for
searching in private property;
Do not make dirty environment
while searching;
Fill with soil back dug plots;
Follow all laws and other
normative for searching objects in
the country you are searching;

4
Do not dig historical or
archeological objects;
Before start looking for different
objects, read carefully normative
legislation of the country, regarding
rights of property over found
objects and those, which concern
cultural belongings of the country.
FITTING GOLDEN MASK 1+
Take the lower end of the strip and
put it in the slit of the coil till them
both fit tight. Put the plastic bolt
into the opening and fit it tight so
that it goes out the opposite side
and turn the nut with light clamp.
Then fit together with the second
part of the strip and put the iron
bolt while tighten it by the winged
nut. Take the electronic set and
unscrew the plastic nut and then
slide it into the upper end of the
tube of the strip, press hard the
plastic end of the detector towards
the tube of the strip. Put the two
tubes one into another as high
according to your height. After that
tighten the nut heavily so that
detector can’t move toward the
strip. Wind up the cable around the
strip leaving an “ear” of the cable
on the lower end of the coil so that
the cable wouldn’t tear when the
coil is gathered and ready to be
transported. Then put the jack of
the cable into the nest of the
detector winding it tightly without
much strength. So the detector is
ready to be worked with.

STRUCRURE AND
OPERATION
- Pot ,,THRESHOLD” - used for
adjusting sound level and regulates
depth. To reach maximum depth,
turn the pot on the right till reaches
its sound level.
.;
- Pot ,,DISC LEVEL”- regulates
degree of elimination of iron
metals;
- Jack ,,HEADPHONES” –used for
headphones;
- Light indicator
“
LOWBATTERY” –indicates lower
tension of batteries.
- Volume control /Golden Mask 1+/
Turning the potentiometer on the
left, till it stops - there will be no
sound. Turning it on the right, GM
1+ will increase the sound.

6
- Volume –On/Off
The Uk Edition has an On/Off
switching potentiometer. When
switched into On, turning it right
you will increase the sound.
*Adjusting the settings
The intensity of separating metals is
done with the help of the pot
,,DISC LEVEL”. If you come upon
non-ferrous metals /gold, silver,
copper, bronze/ a deep-toned sound
can be heard; and if you come upon
ferrous metals a break or a short
sound is heard. Recommended
settings are marked with red.
If you wish to eliminate much more
non-ferrous metals of earth surface,
the pot must be set in a position 8 to
10.
Searching metal objects is made by
moving search coil toward ground
surface /fig.1; fig.2/.
фиг.1
фиг.2
Precise position of a metal can be
fixed with the help of movements of
searching coil into two
perpendicular axes.
* Recharging the batteries.
Batteries possess about 500-600
cycles of re-charge before they

damage, but these are values that
can be reached in certain laboratory
conditions. The detector is supplied
with NiMh batteries. Before start
working with the detector batteries
have to be charged with the help of
the charge device which is also
included in the set. Once charged,
batteries can be used about 40
hours.
If a light “Low battery”appears
while using the detector that means
you have to stop using it and re-
charge the batteries. Put the jack of
the charge device into “CHARGE”
nest and place the device into
electric net from 100 to 250V. All
Golden Mask metal detectors come
with a smart charger. The smart
charger automatically recognise
when the battery is full. When this
happens the red light will change to
green. It’s not necessary to keep
eyes on charge device, because it is
supplied with automatic turn off
and batteries couldn’t be damaged
no matter how long they will stay in
the charge device. When they are
ready pull the device out of the
electric net and take the jack out of
the “CHARGE” nest.
MAINTAINANCE
Keep your detector of blows, jars
and plunges in water the
electronics. Coils are waterproof
and they can be plunged. Do not
open battery box. If it’s necessary,
please inform the seller or the
service-man. If you stop using the
detector, blow dust and send away
of the apparatus and wipe it with a
wet piece of cloth. Do not use
alcohol, spirits, benzine or other
diluents. If you use the detector in
parcels where ammunitions or other
explosives can be localized be
careful –the producer or the seller
are not responsible for your actions.
Warranty
The detector Golden Mask 1/1+/1+
UK Edition is offered with 5 years
of guarantee of electronics, labour
and materials used, for harms which
are not caused on purpose or
irresponsibly. We can upkeep your
device after period of guarantee if it
is necessary.
Attention: Do not turn on the
detector if there are big temperature
amplitudes outdoor and indoor in a
hot room. Wait for 20-30 minutes
and start using the detector.

8
Do not turn on the device while
batteries are re-charging. This can
damage electronics.
GOOD LUCK!
