about 8 hours of use per charge. The electronic block is placed in a specially
designed leather case with a handy carrying strap during operation.
It is advisable not to remove the leather case for the entire lifetime of the
device.
1.2. Search coils (antennas)
The detector comes complete with a variety of antennas specified by the
customer when ordering or additional purchased from an authorized dealer.
Not recommended the use of self-made antennas or other models like the
original! There is a real risk of damage that is not covered by the general
conditions of the guarantee!
The main antenna of Golden mask Deep Hunter pro is a square frame. It is
made from PVC pipes, flanges and bends d = 32 mm, on which with the help
of cable ties Velcro type mounted antenna, which is made of special multi-
conductor cable. To work with this antenna you need an assistant.
Individual work with the appliance are available round (hand) antennas that
attach to stick to wear. These antennas are suitable for areas where the
movement frame is impossible, as well as demand in residential buildings
(walls, floors, ceilings), the vertical slopes of the terrain and other specific areas
to search for buried metal objects.

2. Principle of operation - high-frequency pulse induction (advanced version)
with multi-channel signal processing to identify the type of metal.
3. Settings and display
Golden mask Deep Hunter pro uses extremely simple intuitive operation,
which includes 4 potentiometer (of these 2 with keys - one for switching the
unit and 1 for the inclusion of special modes), 2 buttons, 1 switch and 1 special
indicator:
- "VOLLUME On/Off" - potentiometer for adjusting the volume and "switch
On" - "switch Off" of the detector;
- "SENSITIVITY" - potentiometer to adjust the sensitivity of the detector;
- "CRACKLE On/Off"- potentiometer for adjusting the frequency of sound in
the absence of metal in the area of search antenna;
In position "On." Detector is in its core search mode. The potentiometer is used
to adjust the frequency of the sound indication in the absence of metal in the
area of the antenna. This is strictly individual adjustment and relates exclusively
to the individual auditory characteristics of the operator. It does not affect the
performance of the detector and is designed solely to provide a better detection
of weak signals.
In position "Off." the detector is switched to "silent" mode, in which during
the search does not provide an audible sound and the presence of a metal object
in the area of the antenna is indicated by a low tone (for ferromagnetic metals -
iron) or high tone (non-ferromagnetic metals - ferrous metals). In this mode,
the detectors sensitivity is lower, but it is suitable for work in conditions of
heterogeneous and/or highly mineralized soil, including the presence of ceramic
residues and/or small metal objects that are not subject to searching.

- "GROUND" –precise 10 - turn potentiometer for setting the system to
eliminate the influence of ground.
- "RETUNE" - button for quick readjustment of the detector and remove the
interference in the searching process.
- "BOOST" - switch the additional amplification of the received signal:
- "OFF" - normal depth of detection;
- "ON" - about 20% extra depth of detection.
(After turning in the "ON" position must be made initial system setup to
eliminate the influence of ground);
- "SIGNAL" –analogue meter indicating the strength of the received signal
and level of charge the built-in battery; there are embedded 3 LEDs for
indicating the type of metal and the condition of the battery:
- "Fe", "n-Fe" - LED indication of the type of metal -
green for ferromagnetic metals and red for non-ferromagnetic metals;
- "Battery!" - LED for indicating less than 10% residual charge the built-
in battery, whereby it must be loaded (see item 8);
-"Battery Check" –button to check the level of battery charge. This button
can be used at any time. When the arrow is in the red sector, the battery should
be charged!
4. Eliminating the influence of soil (ground balance).
Using manual method to eliminate the influence of ground requires an initial
setup. The purpose of this adjustment is to remove the signal caused by soil
which for the detector is a "subject" similar to metal. The device is able to
subsequently fine-automatically be retuned to changes in the level of soil signal
(the signal from the ground), but it is necessary to set the initial level, which in
different areas may be different. This is done in order to exploit the maximum

sensitivity of the device in all areas. The process is known as "Ground Balance"
and have to be done mandatory before beginning of work, no matter what the
environment in which we are looking for metal objects.
This process includes the following activities:
1.Search antenna must be placed on the ground in an area where it is assumed
that no buried metal objects.
2. The potentiometer "CRACKLE On/Off" should be set to "5".
3. Set the value of the desired sensitivity of the device (depth of detection) with
potentiometer "SENSITIVITY" (larger values provide high sensitivity).
The values that are selected depend on the nature of the environment in which
will be done searching - in "light" soil can be initiated with values around "7"
÷ "9"; in "heavier" soil it is better to choose the value "5" or less in the scale of
the potentiometer. Subsequently, this value can be increased to the maximum
possible for the conditions.
4. Turn potentiometer "GROUND" in the direction counterclockwise to stop.
Then turn it in the direction clockwise to do 5 turns. Such way it will be set it in
its middle position.
5. Turn the "VOLLUME On/Off" in a clockwise direction to be switched
“On” the detector and set the level of the volume. Values around "6" ÷ "8" on
the scale of the potentiometer are usually sufficient for the job.
6. Turn "GROUND" in the direction counterclockwise to the emergence of
sound - "hum" or "pop" (setup known as "threshold").
Achieving such a setup is very important for a successful operation and
maximize the potential of the detector.

7. Lift the antenna above ground surface to the height at which it will be used
during the search (about 10 cm).
If after lifting the antenna needle on the meter "SIGNAL" deviate to the left of
the position "0", this means that under the antenna was metallic object and the
initial setting is not performed correctly. Move the antenna to another location
and repeat actions 1 to 7.
8. Press and relies button "RETUNE".
9. By the potentiometer "CRACKLE On/Off" can be tuned the frequency of
the sound that will be heard during the searching when there are no metal in the
antenna area.
When there are the presence of a metal object within the scope of the search
antenna this sound began to increase in frequency. In order to detect the
smallest changes in the frequency of the sound indication it is very important
the choice of initial frequency tuning. This setting is highly individualized and
performed "by ear." While working with the accumulation of experience
operator will establish the most appropriate setting for yourself.
10. Again pressure for a short time and release button "RETUNE".
After completion of the above actions setting is completed and the detector
can be used to detect metal objects.
5. Search for metal objects with frame antenna
Golden mask Deep Hunter pro is designed to be used with big size antenna
type "frame". This is the main way to search for deeply buried metal objects.
The antenna should be moved slowly at a constant height (about 10 cm or
more) above the ground. Antennas type "frame" is delivered in the form of
"antenna cable" in length corresponding to the respective size of the frame and

GM Electronics Ltd.

a set of plastic pipes and fittings for assembling the supporting structure of the
frame.
The “antenna - cable" is composed of series-connected conductors in multi-
conductor special cable, which form a coil with certain parameters. It is
mounted onto frame of PVC pipes, joints and elbows, and fixed using the
enclosed cable connections type "Velcro". The connecting cable is plugged into
the connector labeled "Coil", which is mounted on the right edge of the front
panel of the electronic block. Connecting cable must be tightened after placing
connector.
Search with "frame" needs an assistant who helps the horizontal movement of
the frame, using one of the enclosed belts. With another belt operator brings the
detector and determines the height and direction of movement.
There are other ways for individual work with antenna type "frame" in which
the operator stands inside it and thus moves, holding both belts.
Categorically prohibits the use of this method, and "entry" to the operator or
another assistant on the "framework" of a metal detector Golden mask Deep
Hunter pro detector in working!
Adverse effects of the electromagnetic field can lead to serious health
problems and / or injuries!
Failing to work with assistant recommended "dragging" of the antenna for this
purpose can be used device type "sledge" made of non-metallic materials. This
device must provide a constant height (about 10 cm) frame above the ground.
Demand should always begin with a brief pressing the "RETUNE", which is
recommended to be carried out periodically during the search, in order to
maintain maximum sensitivity.

The movement of the antenna must be carried out in parallel strips (bands)
which overlap by up to 30% in order not to miss a portion of the field. The
speed of movement should be about 1m/s.
6. Search for metal objects with round (hand) antennas
When the terrain does not allow search "frame" Golden mask Deep Hunter
pro can be used with smaller (round, "hand") searching coils (antennas)
mounted on a special stick for individual work. Search with such antennas does
not differ materially search "frame".
Since the detector is not designed to detect coins and small metal objects with
"hand" antenna should not be expected to detect these objects. Its purpose is to
replace the "frame" in inaccessible areas and provide an opportunity for
individual work (without assistant).
Moving with "hand" antenna should be carried out very slowly. Unlike
traditional VLF metal detectors using the principle of inductive balance,
Golden mask Deep Hunter pro can detect metal objects without motion. The
movement is only necessary to identify the type of metal, such as speed of
about 1 m/s is sufficient. The search height above surface with "hand" antenna
must be about 5 cm or more.
All activities recommended for use with antenna type "frame" apply to work
with "hand" antenna.
7. Indication the presence of a metal object in antenna area
The signal from a metal object, located in the area of the search antenna is
indicated by increasing the frequency of the sound signal.
Most weak signals, the operator can register are captured by doubling the preset
frequency of sound with "CRACKLE On/Off". This is perceived accurately
by the human ear and therefore it needs to be set very precisely, so that the

GM Electronics Ltd.

sound frequency without the presence of a signal to be only a few Hz (sounds
like crackles).
Each "signal" has "start" and "end". Golden mask Deep Hunter pro has very
well expressed "zone" indication signals from deeply buried metal objects in
search with frame. The length of this "zone" is a guide to the depth of the metal
objects. When this length is greater than the size of the search antenna and has a
characteristic peak in the middle - certainly refers to a deeply buried object. If
the signal is of a short duration (area), but captures only a central part of the
antenna, then also expected discovery of deeply buried metal object. Two-time
audible indication corresponding to the passage of the sides of the "frame" over
the metal object are sure indication of shallow buried small metal objects.
The use of round (hand) antenna gives a slightly different (more "short") signal
compared to the frame. This is due to the physical size of the antenna and must
be considered in determining the area where the expected opening of the metal
object.
After reaching a certain level of the signal (which will be observed in the
indicator "SIGNAL"), it will be carried out indication of the type of the metal
through the LEDs mounted in the indicating "SIGNAL". The red color
indicates a non-ferromagnetic metals and green - for ferromagnetic metals
(iron).
There may be a discrepancy and indication of the type of metal as it depends
on many factors which impulse metal detectors can not always be accounted
for properly.
Once "detected" metal object is repeated over alleged passing zone, outside
zone press briefly and relies button "RETUNE" and then passes from different
directions.

With the acquisition of some experience anyone can learn to recognize the
nature of the various signals, which will guide him in making better use of the
capabilities of the device. It depends to some extent and precise adjustment of
the ground balance and properly selected starting frequency sound indication.
8. The additional signal amplification ( "BOOST")
The additional amplification of the received signal provides increased depth of
detection, but its use is recommended only after acquiring some experience in
working with the unit.
After turning "ON" the "BOOST" set potentiometer "SENSITIVITY" to
"5". All settings are carried out as specified in item 4.
Turn clockwise "SENSITIVITY" to the highest value which is possible to
achieve the setting "threshold".
It should be recognized that setting the apparatus of "threshold" can be
performed by "GROUND", and/or by "SENSITIVITY", and depending on
whether it is included further amplification of the signal, the set-point will be
different.
Working with different values of "SENSITIVITY", and using the extra gain
with "BOOST" assume different behavior of the device.
9. "Silent" mode
In "silent" mode detector can be switched with potentiometer "CRACKLE
On/Off." set to "Off". This mode can be choose at any time of searching
process.
In "silent" mode the crackles are not hear and presents of metal will be indicate
with dual tone - "high" - for non-ferrous metals and "low" - for ferrous
metals.

GM Electronics Ltd.
Golden Mask Deep Hunter pro2 –Instruction Manual
11
In this mode the sensitivity is lower, but this mode is particularly suitable for
highly "polluted" sites (where available numerous small, mainly iron, metal
objects that are not subject of searching ).
In "silent" mode achieves a "rejection" of adverse metals and much more
efficient search of objects with larger sizes.
10. Charging the built-in battery
To ensure maximum longevity of the built-in battery it has to use to charge only
the supplied charger Golden Mask extra special battery charger.
Regularly check the charge level of the built-in battery with button "Battery
Check" (inspection is possible only when the detector is switched “On”) and
stop after work when lit red LED "Battery" (located in the lower right corner of
the indicator).
To make a charging built battery:
1. Turn “Off.” the detector, remove the antenna jack of "Coil" and turn charger
jack in connector labeled "Charge" on the front panel of device.
2. Place the detector in an upright position near the contact voltage 90 ÷ 240V
and connect the automatic charger into an outlet.
It flashing LED mounted in the housing charger in red color..
In this state the LED remains until the charging process is complete, then it
turns blue color.
The duration of charge when worn battery is about 6 ÷ 8 hours.
Remove the charger from the socket and then remove its jack from the
connector "Charge".
3. Turn “On” the detector and check the charge level by pressing "Battery
Check" button.

When properly flowed process of loading arms indicator must show a value
greater than "7".
If the reading is lower reconnect the charger and repeat charging.
11. Replace the built-in battery
To replace the battery should contact the dealer from whom it was purchased
metal detector. It will provide information on how the rules and conditions for
replacement - warranty and post warranty.
Categorically prohibit any attempts to be replaced with integrated battery other
than those offered by the manufacturer batteries.
10. Relativity depth of detecting metal objects in different modes
Golden Mask Deep Hunter pro enables the operator to combine the settings
of the device and its use in 4 different modes of operation.
When working on "heavy soil" sites are preferred modes with a lower number.
The relative depth of detection is determined based mode №3at equal values of
the potentiometer for adjusting the sensitivity SENSITIVITY.

NOTES:
1. After the initial ground balance was done the value of potentiometer
"GROUND"may be increased to one - two graduations on the scale. This
setting is made more "rough" sensitivity of the device and depth decreases
slightly, but achieved greater stability and higher accuracy readings of the
system to recognize the type of metal.
2. During the initial setup ground balance do not switch the detector in "silent"
mode!
3. Use the further gain of the received signal "BOOST" requires mandatory
doing a new initial setup.
4. If at work appear random disturbances or prolonged change the frequency of
the sound signal (false signals) - must be pressed briefly "RETUNE".
This action can be repeated several times until no interference to carry out a
new initial setting in "manual ground balance" or reduce the sensitivity and/or
exclude additional signal amplification "BOOST" in "automatic ground
balance" (item 4).
5. When switch "Off" detector can be observed for some time lights LED
"Battery!". This is not a problem with the battery. Only when this indicator
lights up when turned "On" (running) machine, then you should proceed to
charge the built-in battery.
6. To maximize the potential of the device during operation it is advisable to
pressure short "RETUNE" from time to time.

7. Keeping permanent height above surface during the search will ensure
optimal functioning of the systems to eliminate the influence of ground and thus
the maximum depth of detecting metal objects.
8. Do not use (or leave) the detector in a humid environment, wet bushes, snow
and/or water –it cannot work stability and can be damaged electronic block
(not sealed) and built-in battery. When you connect the antenna to the
electronics must prevent the ingress of water or moisture in and around the
contact pins of the connectors.
9. Work with the detector in industrial areas and places with a large amount of
scrap metal in the soil, and presence of industrial electromagnetic interference
can manifest instability and/or inability to work. This necessarily requires
reducing the sensitivity of the device with the potentiometer "SENSITIVITY",
which will reduce the depth of detection, but this is the only way to achieve
stability and demand in such conditions.
10. After extensive work with the detector, suggesting repeatedly accession and
separation of the antenna may appear defect connectors, which is why these
activities should be carried out very precisely and carefully. Contact points
should be kept clean and dry.
11. If after lifting the antenna from the ground indicator "SIGNAL" show a
negative value (arrow deviates to the left of zero), this means that under the
antenna was metallic object during the preparation of the unit to work.

GM Electronics Ltd.
Golden Mask Deep Hunter pro2 –Instruction Manual
15
In such a case - move the antenna to another location, turn on the device again
and do again initial settings (item 4), then press briefly button "RETUNE"
and continue the search.
12. Please leave the detector switched “On” for about 15 minutes in the area of
work before it can be used to search for metal objects. During this time the
electronics are "self-adjust" to the ambient temperature and the detector reaches
optimum operation.
13. Do not attempt to use the detector after tripping indication consumed charge
the built-in battery. This can result in damage to electronics.
14.Always keep the electronics clean from dust, moisture and fat. Use only dry
and soft cotton cloth for cleaning.
15.If you use the detector in areas where it is possible presence of buried
weapons and/or explosives provide all precautions because the manufacturer
and dealers are not responsible for the consequences resulting from such use
of the detector.
16. If you are looking for metal objects in areas where it is possible to be laid
underground lines on the grid - must call the relevant authorities responsible for
the maintenance of these lines or perform excavation without their permission.
This is especially important for regions in and around the settlements and
industrial sites.
The same goes for underground gas supply installations of oil and/or fuel and
other underground facilities.

17.The use of high-quality headphones (not available at box) connected to the
socket "PHONES" helps achieve even results.
The manufacturer and dealer are not liable for damages or injuries that
could result from digging up the soil.
