2 Hardware operation
2.1 Assembly of GPA probes:
GPA search method requires a probe.
2.1.1 Universal probe 60cm
Connect the telescope rod to the probe as shown and fasten the screw with
the included Allen key.
Join the electronic unit to the other side of the telescope rod as shown
Plug the probe in to the “GPA”-socket of the electronic unit.

Fig. 2.4 Assembled GPA 3000 DR Universal probe with tablet holder
When searching with the universal probe, the telescopic rod should be vertical to the
ground and the universal probe should be held as shown in the picture.
2.1.2 Super probe 1m
Plug the two pieces together and fasten it with the adjusting screw as shown.
Note when re-packaging, you should remove the knurled screw and carefully
pull the super-probe apart to avoid damaging the inner cable.
A 20 cm supplied square tube serves as a spacer between electronics unit and
super probe. The square tube is attached to the top end of the super probe with
a thumbscrew, and the top of the square tube is secured to the electronics unit
with an Allen key.
Plug the probe in to the “GPA”-socket of the electronic unit.
It is recommended not to disassemble the probe after every use.

3 Electronic unit
The GPA 3000 DR has a lightweight and robust housing with easy handling and
operation. The GPA 3000 DR is a measuring device, which can measure alterations
of ground anomalies caused by metal objects, soil structure or excavations and can
discriminate from normal ground magnetism. Correct results strongly depend on
ground type and measuring method. Areas to be measured should not have electric
fields (like high voltage cables or earth wires) or strong mineralised or wet grounds
because they influence the measurement. The dryer the soil, the more precise the
results.

3.1 Connection to the drone
If you want to connect the GPA 3000 DR to the drone, you should connect it to the
upper part of the electronics unit (connection to the drone).
The electronics unit has a transmitter antenna which sends search data to the
receiver. Attached to the tablet is the receiver, which receives the transmitted data and
transmits it to the tablet. This tablet with the radio station should be located next to the
remote control of the drone, so you can control the search data.
When searching with the drone, the supersonic probe should be fixed so that the
probe is perpendicular to the ground.

Velcro on the backside of the tablet
Note: When connecting the tablet with the radio station, you should first put the
cables in the radio station and then connect with tablet
3.2 Commissioning of the electronics unit

4 Search methods
4.1 GPA search methods
There must be a probe connected to the electronic unit to use the GPA search
method.
4.1.1 Search with the universal probe
Switching the electronic unit on via On-/Off-button.
Select your language.
Select “Universal probe” at the probe selection.
The electronic unit should face up while using the probe
Optionally the tablet computer can be connected to the electronic unit via
Bluetooth. (See 5.2)
Place the universal probe so that one of the square ends shows in the direction
you want to search and check both, calibration value and sensor value.
Turn the probe 180° so that the opposite square now face forward and check
the two values again.
Choose the side with values closer to 2.5 as forward direction (as shown in the
following figures).
The distance between the probe and ground should not vary a lot.
Avoid hectic movements and try to walk in straight lines.
