About the Golden One Metal Detector
The Golden Mask One is an entry-level metal detector with xed ground balance, with few
and simple controls, but powerful and sensitive - the best choice to jump into the metal
detector hobby with low budget, but with a modern and performing metal detector. The
xed ground balance means all you have to do is to switch-on your detector and start the
search - no need to set the ground balance, your machine is always ready to go.
The Golden Mask One is a mixed analogue/digital technology machine that combines
depth and recovery speed at the same time. It is oered in two versions with working
frequency of 15 or 24 kHz. Everything else is exactly the same.

Operating the Golden Mask One
The Golden Mask One is designed to be as simple to operate as possible.
The controls of the detector are 5 buttons on the front panel of the control box and a
switch on the back side of the battery box to control the wireless transmitter for the wire-
less headphones (if you purchased this option).
On the LCD screen are shown all the working parameters of the detector, the TargetID
number and the Spectrum VDI scale, where a graphic of the target signal response is
shown to help identifying the target detected.
On the graphic below you can see the LCD screen indicators. Buttons will be explained
later.
Main Parts and Assembly
Your Golden Mask One comes in a box that contain: the detector with telescopic carbon
shaft and a search coil. By default, the One is delivered without batteries, charger and
wireless headphones. You could have these as options: 10 x 1500 or 2500mAh AA NiMh
rechargeable batteries (this could be subject to change, while shipping batteries in some
destinations is prohibited), GM Smart charger and wireless headphones WS 105 or WS106.
In the box you will also nd a warranty card, invoice and other purchase papers (payment
statement, packing slip - may vary upon payment method and destination country).
There is nothing special assembling the detector. You have to attach the coil to the lower
stem of the shaft, using the supplied plastic bolt and screw (they are already on their
place), then attach the coil cable to the main unit. If your detector is purchased without
batteries, you must open the battery compartment, extract the battery cassette, put-in
10 AA batteries (Alkaline or NiMH), but the battery cassette back in and close the battery
compartment. Now you are ready to go.
To extend the telescopic shaft, start from the rst section by the side of the coil. Turn the
xing screw counter-clockwise, pull the search coil gently to the full extent of the carbon
pipe and then x the section by turning the xing screw clockwise. Do the same with the
second section. Check if the length is enough, if not, extend the third section to match the
desired length.
WARNING: The third section can be pulled out completely from the handle part to make
your detector even shorter and easier to transport. Please, be sure to have a minimum of
15 cm (6 inch) of the third section inside the xing screw of the handle section, otherwise
the stem will not be stable enough and could be broken, especially if a large coil is used.

Turning on and o the detector
To turn on the detector, hold the ON/OFF button for 2 seconds - a world map graphic
and the Golden Mask logo will appear on the screen. From this stage to operation stage
around 10 seconds are required for the detector software to load.
WARNING!
THIS PART IS VERY IMPORTANT,
READ IT CAREFULLY!
When you turn on the detector, the coil must be at
least 50 cm (20”) high from the ground, and far from
any metal objects. After the software loads, the detec-
tor performs a RESET of the electronics to pair the detector with the coil, according to
the surrounding temperature and electromagnetic elds (if any). You can manually do a
reset at any time by pressing the ENTER button.
If the surrounding temperature is changing quickly, the detector may become nervous. In
this case you should perform a reset prior of making any other changes, the reset resolves
the problem in 99% of the occasions.
To turn o the detector, press and hold the ON/OFF button. A screen with HOLD TO TURN
OFF will appear.
Hold the ON/OFF button until a POWER OFF screen appears and then release the button -
the detector will turn o after a second.

Selecting the menu options
The menu of the Golden Mask One consists of only four positions: FREQUENCY, GAIN,
IRON VOLUME and SOUND VOLUME. To select one of these positions, you shall use the
MENU button (What a surprise!). When you push the MENU button, the rst position of the
menu is selected and the label of the position is inverted - the letters become white on
a black background. To go to the second position, push the MENU button again, do the
same for the next two positions.
To set a desired value of a menu position, use the + and - buttons. When you are ready,
push the ENTER button to exit the menu and enter the working mode.
Let’s explain the menu settings:
Frequency
At this position of the menu, you control the so-called Frequency shift - this is a slight
change of the working frequency of the detector. The change is tiny, but could have great
eect to avoid interference with EMI sources of dierent kind, for example from other
detectors, running at a similar frequency. There are three positions available - 1, 2 and 3.
Use the + and - buttons to select the desired value.
Note that this position consist of two numbers divided by a dash. The rst number is
the working frequency of the detector (15 or 24 kHz) and it never changes. The second
number is the frequency shift number - 1, 2 or 3. That simple.
Gain
The Gain controls the sensitivity of the detector or the depth of detection. This setting has
numbers from 0 to 30. In general, you will set the maximum value the detector is stable at.
This means you set that value at which you could run the detector comfortably - without
lot of ghost signals and without EMI disturbance. Running your detector comfortably is
more important than the depth itself. Yes, some detectorists work over the threshold - this
means with Gain (Power, Threshold) over the comfortable border, and this way they could
have a little bit more depth. But this technique is not recommended - you will suer from
the nonstop beeping, you have to strain your hearing and this is painful.
WARNING:
Zero (0) Gain does not mean zero depth. At Gain 0, the detector still has some good depth,
around half the depth at Gain 30.
Why should you set a much lower Gain than the maximum possible? Because a lower Gain
setting will allow you for example to go deeper in highly mineralized soils. Yes, this is true
- if you experience diculties working on a particular soil, you shall lower the Gain and
this helps almost always. Also, a lower Gain will allow for better target separation abilities
of your machine - this is useful on iron-infested sites like former settlements, wine yards,
farms and so on.

Iron Volume
By default, the One is a Dual-Tone machine and it emits two sound tones - a lower tone for
the ferrous targets and a higher tone for the nonferrous targets.
The Iron Volume setting is used for two purposes: it controls how loud is the sound from
ferrous targets (Iron) and it is used also to run your detector in Mono-Tone mode.
This settings has 7 values. At the default and the highest value of 7, the sound response
from ferrous and nonferrous targets has the same volume. When you set lower values,
you keep the volume from the nonferrous targets at the level set with the Volume (next
position in the MENU) and lower the volume of the sound, returned from ferrous targets.
This is useful on iron-infested sites, where the detector is emitting sounds constantly -
lowering the Iron Volume you will experience a much comfortable search, but you will not
miss any “good” target as the sound from nonferrous targets is louder.
As said above, the One is a Dual-Tone machine, but it could work also as a Mono-Tone ma-
chine. When you set the Iron Volume at Zero (0), the detectors runs in Mono-Tone mode.
This means you will not hear sounds from ferrous targets or they will be marked with
kind of low crackling sound. In this mode the detector achieves a little bit better depth. If
you could get used with this mode, we recommend that you use it always when possible.
With the help of the VDI numbers and the Spectrum graphics, you will easily identify your
target.
Sound Volume
This a setting that controls the overall sound volume. Nothing special here - values could
be set from 0 to 10. At zero (0) the detector is silent - no sound is emitted.
Target ID, Spectrum VDI
Target ID and Spectrum VDI are two ways for target identication.
Target ID is a number, shown at the top-right corner of the LCD display. Ferrous targets are
shown with negative numbers (e.g. -5), while nonferrous targets are indicated with posi-
tive numbers. The border between ferrous and nonferrous targets is 0. The more a target
is placed to the right end of the VDI scale, the greater the Target ID value. And vice-versa.
The Spectrum VDI is in fact a graphical presentation of the real signal, returned by the de-
tected target. It contains a great volume of information about the target, so experienced
prospectors could easily guess what’s under the coil only by looking at the Spectrum VDI
graphic. The graphic itself consist of thin bars with dierent height, placed above the
VDI scale. The position of the bars left/right on the VDI scale depends on the metal type.
The height of the bars depends on the signal strength - the stronger the returned signal,
the longer the bars. Fewer and longer bars mean strong signal and big/shallow target.
Stretched left-right graphic means stretched and/or multi-metal or rusty target.

Iron Audio and Target Reject
The Iron Audio function works in relation with the TargetID function. It is used to reject
certain metals from left to right on the target scale. A black bar shows which metals will
sound as Iron or will be completely discarded when the detector is in Mono-Tone mode.
To set the Iron Audio, press the + and - buttons while the detector is in working mode. You
will see the right border of the black bar moving left or right.
The default value of the Iron audio is zero (0). At value 0 the iron bar is set between the
Iron and the Foil on the VDI scale. This means targets with ID more than 0 will sound as
nonferrous, and those with ID below 0 will sound as ferrous.
Let’s clarify with an example: if you want to not dig foil, you shall set the black bar to cover
the foil section on the VDI scale. This way the foil will sound as Iron. But please be very
careful on how you use this function to not miss good targets. For example, tiny thin gold
coins are very often identied as foil. If you set the Iron Audio to reject foil, you will lose
also such thin gold coins. Tiny gold jewellery pieces also return an ID in the Foil section.
So, be careful - it’s better to dig some foil than to miss some gold.
If you set the Iron Audio bar at the full-left position (-22), the detector works in All-Metal
mode. This means the sound from all targets will be the same. You can still identify the
target by the VDI number and the SpectrumVDI bars. In All Metal mode, the detector gains
a little bit more depth, but this mode is good only on clean places with very few targets.
Otherwise you will have to constantly look at the screen and this is not quite comfortable.
Turning-on the backlight
To turn-on the LCD screen backlight, just short-press the ON/OFF button and wait until the
LCD is lit and backlight icon appears.
To turn the backlight o, again short-press the ON/OFF button. As simple as that.
When the backlight is activated, a small icon appears below the battery icon on the main
screen to show you switched the backlight on. The backlight does not consume much
power, but is better to not switch it on during the day.
Controlling the LCD screen contrast
You can change the LCD screen contrast. To do this, short-press the ON/OFF button, then
press the - and + buttons within 3 seconds after you’ve pressed the ON/OFF button. If you
don’t press any button within 3 seconds, the backlight will be activated or deactivated.

Using the optional wireless headphones
Your Golden Mask One could be purchased with optional wireless headphones.
At the backside of the battery compartment you will nd a small switch that routes the
sound signal to the speaker or to the wireless transmitter. To use the wireless headphones,
you just switch to WS position and the sound goes to the wireless transmitter. Now you
have to switch-on the headphones by pressing and holding for 2 seconds the on/o but-
ton. When the headphones are ready to work, a LED will start to blink.
NOTE: The default version of the detector is delivered without wireless headphones and
wireless transmitter. It does not have the WS/SP switch.
Charging the detector batteries
The Golden Mask One is delivered without batteries by default, but you can order it with
10 x 1500 or 2500mAh 1.2V AA-size NiMh rechargeable batteries (this is subject to change,
while shipping batteries in some destinations is prohibited).
Charging could be done with a Golden Mask Smart Charger (optional or purchased sepa-
rately) without the need to pull-out the battery pack. Just connect the Golden Mask Smart
charger jack to the charging port of the detector on the backside of the battery box. A red
light will be lit on the charger. After the charging is complete, the light will turn to blue
color. You can now disconnect the charger and start using the detector.
ATTENTION! Do not turn on the detector until the charging process is nished and
the charger is disconnected! Otherwise the detector electronics may be damaged!
You could also pull-out the batteries and charge them with any standard charger for NiMH
batteries. A microprocessor charger is strongly recommended to ensure the correct charg-
ing and the long life of the rechargeable batteries. You can replace the supplied batteries
with any standard-size NiMH 1.2V rechargeable batteries of type AA. You can also use
standard AA 1.5V Alkaline batteries.
WARNING!
Never try to charge non-rechargeable batteries!
Do not connect the charger to the detector when
inside the battery box are installed non-recharge-
able batteries! Such action will cause re!
Some advices
The Golden Mask One comes in a standard set with a 23x25 cm (9x10 inch) multi-
frequency search coil. A coil with this size is considered universal - it could be used with
success in every aspect of metal detecting - from gold prospecting to treasure hunting. Of
course, there are better option for these, but the default coil works quite well.
You can buy additional coils with dierent size and shape from 13 cm to 30 cm. The One
is compatible with all multi-frequency coils produced by Golden Mask. These have an
orange or yellow point on the cable protector at the coil top. Non-compatible coils do not
have the same point or have a white one.
Smaller coils are better for small targets as gold nuggets, jewellery and small coins, while
the larger coils are best for large targets - large coins, relics and treasures.
Larger coils are not always deeper. Depth depends on the target size and the working
frequency. For tiny gold jewellery a small 18 cm coil and a 24kHz One will work better than
a larger coil. Even more, you could easily miss small jewellery and tiny coins if you search
with the a large coil. Larger coils are deeper on large targets only.
For beach hunting, where a combination of both mineralization and conductivity is
present, a smaller coil will work better.
Speaking about tests, do not try to test the detector at home - in every house or even far
from a house there are always too many electromagnetic interference (EMI) elds that will
disturb the detector and you may think something’s wrong.
On sites with not too many targets, try to use the All metal mode - this will give you 2-3 cm
more depth. If you cannot get used with All metal mode, try to use the Mono tone mode.
On mineralization, decrease the Gain until the detector becomes calm. On strongly miner-
alized ground, a low value of the Gain very often gives you more depth and more correct
target identication.
Try to swipe the coil near the ground, but without touching it. Do not move it too slow or
too fast. With practice, you will nd the appropriate speed.
Pay attention on the sound. With practice you will learn to successfully distinguish dier-
ent sounds. Some experienced detectorists can distinguish dierent type of targets with-
out even looking on the screen. For example, you can easily distinguish the sound from a
coin and a lead bullet, just have to listen carefully. But to do this, you will have to practice a
lot. This is the same as with car driving - remember your rst days driving?
Respect the private property. Do not search in private property without permission - this
could lead to serious legal, nancial or other type of punishment.
Respect the law in your country about the protection of historical heritage and archeo-
logical sites. In all countries in Europe it is strictly prohibited to do metal detecting on or
nearby archeological sites.

Cautions
Keep the detector electronics and battery compartment from water and moisture. Be very
careful when placing your detector on wet ground - moisture can penetrate batteries and
brake the electronics inside the battery compartment.
Keep the search coils from mechanical impact - stepping on your coil almost always brakes
it, and the warranty does not cover this. The search coils are water-proof. You can wash
them or submerge them in water - no problem.
Keep the coil connector from dirt and moisture. The good contact between the coil and
the detector is essential for the performance of the machine.
Do not use other charger than the supplied with your machine to charge the batteries
inside the detector. Third party chargers may be very dangerous for the batteries and may
cause re.
Do not forget to turn o your detector after you end searching - if you do it, this could ruin
the batteries and the electronics inside the battery box.
Good Luck!
