1 General guidelines
1.1 Preface
Congratulations on your purchase of one of the most advanced high performance
detectors: the GPA 3000.
The GPA 3000 is the new development of KTS-Electronic GmbH & Co. KG. Our
professional 3D ground scanner is equipped with the most powerful sensors.
The GPA 3000 set includes the new 1 meter super probe, in which different sensors
are built-in. These sensors are selected by pressing the search depth button. Without
the need for an exchange of probes the search power can be chosen in a range of
10 m to 25 m. Besides the KTS 3D software the new "GPA Visualizer" software is pre-
installed on the tablet computer; this enables an easy operation without the need for
previous knowledge.
Already pre-installed programs and an instruction manual which is furnished with
numerous illustrations and easy to understand will facilitate the assembly, so that
nothing will stand in the way for a practical application.
This instruction has been developed by KTS-Electronic GmbH & Co. KG. Any
alterations or duplications are only allowed with written permission of KTS-Electronic
GmbH & Co. KG. KTS-Electronic GmbH & Co. KG reserves the right to modify the
instruction with new knowledge at anytime. The new instructions can always be
downloaded gratuitously from our website.

2 Hardware operation
2.1 Assembly of probes:
GPA 3000 Universal probe 60 cm
As a first step plug the telescope bar into the probe’s mount. Then insert the remaining
parts in correct order. The universal or super probe can now be fixed to the holder
under the electronic unit.
Afterwards the sensor cable must be connected to the electronic unit. Now your device
is ready for use.

Mounted GPA 3000 with carbon rod, cable and cable connection to electronic unit.
Hold the probe so that the arrows (attached laterally) point to the ground during
search. The arrow on top should point to running direction. This way you will attain the
highest search performance.

KTS-Electronic GmbH & Co. KG - GPA 3000

GPA 3000 Super probe
Plug super probe into the provided shaft ...
... and connect it to the electronic unit by using an allen key.
Hold the super probe in the same
manner as the universal probe, i.e.
the arrows must point towards the
ground.

2.2 Electronic Unit
The newly developed electronic unit impresses with an updated design and through an
easy handling. By pressing the ON-/OFF-button the display shows all necessary
informations at a glance.
Sensor: Sensor value
Calibration: Calibration value
Strength: Search depth
Battery: Battery condition (graphically represented)
The calibration is conducted by a microprocessor and is carried out on every soil
automatically. Further modulations are not necessary. Therefore the GPA 3000 set is
applicable on every soil type.
Via Bluetooth® the measured data is digitized automatically and transformed
wirelessly to the tablet computer.The blue LED flashes after activation, constant light
signifies the Bluetooth® connection.
2.1 - Front of electronic unit (GPA 3000)
2.3 Start of electronic
The Bluetooth®-connection allows a fast and save transfer of measured data from
GPA 3000 to the tablet computer –contrary to other devices, which record data via
parallel interface.

KTS-Electronic GmbH & Co. KG - GPA 3000

By pressing the ON-/OFF-button the current battery condition can also be controlled
(graphically represented). At the same time the sensor and calibration data is shown.
The sensor data should always be between 2 to 3, the calibration data approx. 2.5
(before the calibration automatically is set, display could temporarily indicate other
values).
With the push button beneath “Search depth” the desired search performance is
determined and a switch between the different sensors is made possible. The chosen
search depth will be displayed in the row “Strength” (10, 15, 20 or 25 meters).

4 Search process
During soil analysis several search probes are available, whereby we recommend to
gain experience with the universal probe at first. The search with the super probe is
therefore a lot easier.
4.1 Search with the universal probe
Start with the ON-/OFF-button.
After switch-on display shows battery condition.
Wireless connection via Bluetooth® from the computer to the electronic unit.
Hold the probe so that arrows (attached laterally) point to the ground during
search (this way you will attain the highest search performance).
Check of calibration (approx. 2.5) and
Control of sensor value.
Verify that the indicated value is between 2 to 3. Should this not be the case,
change the search direction slightly so that above value is displayed.
4.2 Search with the super probe
The super probe is similar to the universal probe, but offers approx. 30% more depth
performance. Beforehand it is absolutely necessary to select a search direction where
values between 2 to 3 are displayed.
Start with the ON-/OFF-button.
After switch-on display shows battery condition.
Wireless connection via Bluetooth® from the computer to the electronic unit.
Hold the probe so that arrows (arranged sidewise) point to the ground during
search (this way you will attain the highest search performance).
Check of calibration (approx. 2.5) and
control of sensor value.
Verify that the indicated value is between 2 to 3. Should this not be the case,
change the search direction slightly so that above value is displayed.

4.3 Rechargeable battery and charger
Through the installed 2800 mAh li-ion battery a strong
performance is guaranteed. With the lithium battery
charger the battery can be fully charged within 90
minutes. The actual operating time is approx. 6-12
hours (depending on coil size and the use of
headphones). The charging procedure is indicated by
the orange light emitting diode, the end of the
charging process is shown by green light. After each
charging the connecting cable for the battery charger
should be removed.
A provided voltage transformer enables charging in
the car.
