2. Electronic Unit
Compared to its predecessor the advantage of GOLD SCAN II consist primarily in the
fact that the sensitivity towards gold and precious metals was substantially increased
and the setting was simplified. Instead of several control knobs the new device has
only one ON- / OFF-button and a display that delivers all informations at a glance.
This makes the search considerably easier.
The electronic unit is installed in a stable box and carried in a leather bag.
Power: The new GOLD SCAN II is equipped with only one ON-/OFF-button.
Reset: Automatic zero balance at the touch of a button. By activating the Reset-
button the device will be aligned to the actual soil condition.
Freq.: Frequency adjustment.
Audio: Volume control
Bluetooth (BT): green operating LED for Bluetooth connection with computer.
Display: ID: Presentation of metal type and display of conductivity
BAT: Battery control (graphically and in percent).

2.1 Back side
1. Charger (connection to the charging device / separate plug): For charging the
battery the plug of the charging device has to be plugged into the provided
connector socket. The maximum charging time is 90 minutes (to avoid a defect
on the charger or the built-in battery, please do not exceed this time). The
connector of the charger should be removed after each charge.
2. Headphone socket: Any commercial headphones with 6.3 mm jack can be
plugged in. During use the loudspeaker is turned off. Matching, light weight
headphones are provided.
3. Socket for coils: The connecting socket for coils is located on the left side. The
connector plug of the searchcoil has to be plugged into the socket. Before
removing the plug the locking knob must be pressed, only then an extraction is
possible. The connector is compatible with all GOLD SCAN II searchcoils.
3. Search process
Please note the following:
Stay away from conducting overhead lines
Do not use cell phone during operation
Do not process any measurement during thunderstorms
Protect device from wetness
Accurate operation is only guaranteed with a fully charged battery
For operation or charging only use the components enclosed or released by KTS
GmbH & Co. KG.
GOLD SCAN II is a PC-connected metal detector, which is provided with the KTS-3D
software. First you should use this device like a common metal detector without 3D
software, i.e. search and identify your findings on your display (metal type), then
mark the place of discovery. Later you can scan the spot more precisely by using
your laptop with the KTS-3D software. The handling of laptops and the respective
settings will be explained in chapter 5 (page 15).

The GOLD SCAN II is ready for use within a very short time:
1. Activate the metal detector with the ON-/OFF-button. The respective searchcoil
should be cable-connected to the electronic unit in advance.
2. Hold the searchcoil to the ground and press the Reset-button for a brief
moment. You herewith attain a zero balance, which is necessary for a trouble-
free search.
Please make sure, that there are no metal objects near the searchcoil during
zero balance. This could cause a wrong adjustment of the metal detector and
produce unwanted indicator effects (as the case may be repeat the RESET-
procedure on another, metal-free spot).
3. In the beginning please set the frequency to the lowest level (turn the Freq.-
modulator clockwise). The volume should be set hearable with the help of the
Audio control. Generally we recommend to start with the lowest frequency
adjustment to acquaint yourself with the handling of the device. With advancing
experience it is expedient, to increase the frequency gradually, what will have a
positive effect on the search performance.
3.1 Search recommendations and hints for Reset operation
During the search process be sure that you do not carry items of metal with you. This
could cause a wrong adjustment when pressing the Reset key and can produce false
indicator effects. In addition, this can lead to a false metal discrimination. While
searching be ensured, that the sound remains constant, otherwise a wrong
adjustment caused by magnetic fields may occur. In this case, the searchcoil is held
above the ground and the display has to be observed after renewed actuation of the
Reset-button and the adjustment of the frequency. The GOLD SCAN II has a
constant metal discrimination. Thereby the inserted microprocessor computes the
conductivity of the metal objects and indicates them on the digital display
Note: For a successful search the function of the Reset-button is of utmost
importance.

After each of the following changes please press the Reset-button:
1. After every engaging of the metal detector.
2. After each change of searchcoils.
3. During the search, if sound becomes instable due to bad ground conditions or
geomagnetism.
To create the search more target-oriented and therefore more successful –especially
before excavation –please draw your attention to the following:
1. Change of sound (frequency)
2. Intensity of sound
3. Continuity of sound
4. Extent of value (digital display)
The change of sound is the first sign for the detection of a metal object. Before
excavation, however, further details should be taken into account and the own search
experience should be used for help:
The more intense the sound, the larger the metal object and the nearer the position
to the surface. While the high search tone is audible, it is required to move the
searchcoil in the close surrounding to determine the shape of the metal object.
ID (metal discrimination):
Compared to the predecessor model, in which only a single measurement was
conducted, GOLD SCAN II enables the discrimination by a special measuring
method. Now 5 measurements are carried out, which will calculate the average
value. The average value calculation leads to a more precise metal type
discrimination. The extent of the metal type range makes it possible to distinguish
different size metal objects with the appropriate values from one another. The
average value is shown in sector gold with 100-1000, in the range of copper with
1000-2500 and in the field of light metals, e.g. aluminum, as of 2500.
Unlike to other metal detectors a constant metal discrimination takes place at the
GOLD SCAN II. Conductivity value and metal type (e.g. “Gold”) are indicated on the
display.
Note: The new GOLD SCAN II shows a very sensitive reaction towards small gold objects
(e.g. nuggets). Through the increase of frequency the depth performance also rises. Due
to difficult soil conditions it can occur, that interferences will escalate. With a renewed
Reset and a reduction of frequency this can be lowered.

As long as the searchcoil is exactly located over the metal object the displayed
conductibility value is decisive.
To identify a metal object a weak tone is inadequate. To compute the conductibility of
a metal object a signal with high intensity is necessary.
Please bear in mind that –depending on soil conditions as well as size and shape of
the located objects –the measured values can diversify. The indicated values are
guide values, which can be complemented with your own search routine
See also the explanation of false signals on page 18.
Note: To avoid incorrect conductivity values it is absolutely necessary to repeat the
adjustment of the soil balance. When pressing the Reset-button make sure, that there are no
metal parts in the soil..
3.2 Exact location of metal objects
GOLD SCAN II works with the pulse induction searching system and is able to detect
without setting the searchcoil in motion. While approaching an object with the
searchcoil you will notice an increase of sound frequency. As soon as the searchcoil
is exactly positioned over the object, the highest tone is reached and the displayed
conductivity value corresponds to the probable kind of metal.
With this method not only the exact place of discovery is located, the shape of the
item can also be identified through the sound continuity. For example, a long-lasting
high tone stands in longitudinal direction for a slim object, e.g. a pipe. A high tone in
any direction indicates a ringlike object.
