Makes underground treasures visible Instruction manual 11
How does detector work?
Metal detectors work by 1� transmitting
a magnetic eld generated by coil
and then 2. analyzing that eld as it
returns from the environment that the
signal was transmitted� 3. Processing
of the signal is done by control unit
that 4. generates audio tones when it
detects that return signal has changed�

GOLDHUNTER DETECTOR OPERATES
IN THREE MODES
DISCRIMINATION MODE
This mode is recommended for starters and beginners, it is simple and easy to
use, it provides quick information of type and depth of buried object and good
performance.
ALL METAL MODE
This mode provides even better performance since it enables user to eliminate
false signals caused by soil mineralization and achieve more depth and higher
sensitivity. We recommend to start using it when you are already familiar with
Discrimination mode.
D GROUND SCAN MODE
This mode enables user to scan the ground and visualize targets on the screen.
Before start using this mode, we recommend to rst learn about basics of metal
detecting get familiar with Discrimination mode.

Discrimination mode
How to identify buried objects or what is Target ID?
Target ID is used to distinguish one type of metal target from other� GoldHunter detector offers three Target ID
presentations for beginners and also for advanced / experienced users�
TARGET ID ICONS are most
simple way of expressing metal
target type�
When search coil is moved over
the target icon presenting type of
metal will be highlighted�
TARGET ID SCALE helps user to which group of metal types target belongs to�
When search coil is moved over the target, dot on the Target ID scale classies metallic object as ferrous (iron) or
targets with lower conductivity, nonferrous (gold) targets with higher conductivity�
TARGET ID VALUE - numeric
presentation of target ID�
When search coil is moved over
the target, target ID will be updated
with number form 0-100�

Target ID accuracy
There are many factors that inuence on Target ID accuracy, like soil mineralisation or angle between target and coil, by
gaining experienced in the eld, you should be able to recognised many types of targets by Target ID value.
TARGET ID ICONS
E.g. Iron objects, nails and
horseshoes.
E.g. Aluminium foil and lower
value coins.
E.g. Low and high value coins
and screwcaps.
E.g. Rings, pull tabs and lower

How to determine depth and exact
location of buried objects?
Press and hold pin-point button will help to narrow down the
location of buried object�
During the pin-point mode approximate target depth will be
displayed on the screen in inches�
Relative depth is always displayed on the display as SIGNAL
bars� Strong signal indicates that target is large and massive
or it is small but very close to the surface�
Notice that depth estimation is always approximation & works
well only under ideal conditions, but in reality there are many
factors that can affect depth estimation and also how deep
What does gain knob do?
The higher sensitivity, the deeper or smaller objects can be
detected�
In DISCRIMINATION mode, sensitivity can be adjusted using
GAIN knob�
For beginners it is recommended to start with
gain at middle position or lower, so that you don’t
hear any sound when sweeping with search coil
over clear ground where no metal is present�
Target Size
Large targets can be
detected deeper than
small targets�
Target Shape
Circular shapes (e�g�
coins and rings) can
be detected deeper
than long thin shapes
(e�g� nails or screws)�
Target Orientation
A horizontal coin
(e.g. lying at) can be
detected deeper than
a vertical coin (e�g�
standing on its edge)�
Target Composition
Highly conductive
metals (e�g� silver)
can be detected
deeper than less
conductive metals
(e�g� lead)�
Ground Mineralisation
A target in benign
(unmineralized)
ground can be
detected deeper than
a target in heavily
mineralised ground�
BEEP!
Move 90° and repeat
The intersection of the
two lines marks the exact
location of the target

TREASUREHUNTER3D

How to setup detector to ignore items
like nails, cans & aluminium foil?
Discrimination is ability of metal detector device to eliminate
unwanted targets like trash & metal objects from detection�
When GoldHunter operates in DISCRIMINATOR mode, user
is able to set discrimination level using + - buttons on the
control box�
When discrimination is set to zero (default setting), all targets will generate high tone, indicated by red line.
From the above screen we can see that discrimination level is set to 60, all items with Target ID <45 will not be detected
and will not generate any tone, LOW tone will be generated for targets with ID between 45 and 60 (blue line) while all
others above 60 will generate HIGH tone (red line)�
BLUE and RED line on top of Target ID scale indicates weather
certain target types will only generate lower tone sound or
they will be completely discriminated - this means detector
will not generate any sound for them�
EXAMPLE:

TREASUREHUNTER3D

All-metal mode
How to eliminate interference of ground minerals?
Soil contains iron minerals that can cause much higher signals than buried targets we are interested in� With ground balancing
we calibrate detector device to local ground, this eliminates false signals from minerals , enabling detector to detect deeper
and provide more accurate Target ID results�
TO GROUND BALANCE GOLDHUNTER FOLLOW
THIS PROCEDURE:
1. Enter ALL METAL mode from the main menu�
2. Set Gain to middle position�
3. Rotate Threshold know to the point where you hear
background hum�
4. Sweep search coil across the ground� Make sure you
have found a clear place with no metal present�
5. Press & Hold GG button & raise and lower the coil
repeatedly over clear patch of soil�
6. Observe GND PHASE value, when is settles down to
1 or 2 numbers in variation, release GG button, while
still pumping the coil�

TREASUREHUNTER3D
Makes underground treasures visible Instruction manual 19
What is best adjustment of Gain & Threshold?
In order to achieve best performance in ALL METAL mode, user must learn how to properly set Gain & Threshold�
FOR BEST PERFORMANCE & MAXIMUM SENSITIVITY:
1. Set Gain at low level�
2. Set Threshold to positive value >0, so that you will
hear some background hum�
3. Then increase Gain to a comfortable level�
FOR MORE COMFORTABLE SILENT SEARCHING:
1. Set Threshold to zero or negative value.
2. Reduce gain if necessary�
Manual adjust
User is also able to manually set or adjust Ground Balance
values by + an - button on the control box�
For ne adjustment user should continue to raise and lower
the coil repeatedly over clear patch of soil, if the sound is
louder as you rise search coil, user should increase ground
balance, if sound is louder while lowering search coil, ground
balance should be decreased�
Notice that in the ALL-METAL mode value in the middle
presents GND PHASE or type of ground mineralization and
not Target ID as in DISCRIMINATION mode�
Fe3O4 indicates amount of ground mineralization. If amount
of mineralization is too high detector will not be able be
usable anymore in this scenario try to keep the coil higher
above the ground�
SOME TYPICAL GROUND MINERALIYATION
TYPES ARE:
Wet salt and alkali 0 - 10
Metallic iron. Very few soils in this
range. You are probably over metal. 5 - 25
Very few soils in this range -
occasionally some saltwater beaches 26 - 39
Red, yellow and brown iron bearing
clay minerals 40 - 75
Magnetite and other black iron
minerals 75 - 95

TREASUREHUNTER3D
Makes underground treasures visible Instruction manual 20
Observing & processing scan results
1. Press button in order to observe & process
scanned results in 3D ground scan viewer�
2. Use iOS native touch functions to rotate, zoom or
move 3D scan�
3. Press to enable smart 3d scan processing�
4. Use sliders to adjust processing parameters and then
press to apply them and enhance
target shape�
3D ground scan mode
Performing 3D ground scanning
3D ground scan mode enables user to visualize buried objects.
In order to perform 3D scan of an object user should do the
following:
1. Enter 3D ground scan mode�
2. Hold nger on the circle and align it with the metal -
detector coil, so that the circle will be right in
the middle of the coil�
3. Press Pin-point/Ground Grab button to start
scanning process�
4. Move device left and right in order to calibrate
positioning sensor� Once the sensor is calibrated,
“Scan in progress” message will appear on screen�
5. Move detector coil slowly from left to right over the
area you would like to scan�
6. Once area is scanned, press Pin-point/Ground Grab
button to stop scanning�
