3 Electronic unit
The newly developed compact housing of the GPA 500 XS now contains the
electronic unit of the GPA as well as the GOLD ID-XL and impresses with it simple
handling.
The GPA 500 XS 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 Setup electronic unit
After switching the unit on via On-/Off-button the language selecting screen
will appear.
After selecting your language the option to select a search method will appear.

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 “GPA System” as search method.
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.
Fig.: 14 - Universal probe
Fig.: 15 - Complete universal probe
4.2 GOLD ID-XL search methods
There must be a coil connected to the electronic unit to use the GOLD ID-XL search
method.

KTS-Electronic GmbH & Co. KG –GPA 500 XS
12
4.2.1 Search with 30x30cm search coil
Switching the electronic unit on via On-/Off-button.
Select your language.
Select “GOLD ID-XL” as search method.
Hold the search coil 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.
During zero balance make sure that there are no metallic objects near the
search coil. This could cause a wrong adjustment of the metal detector and
produce unwanted indicator effects.
Repeat the zero balance process after soil-changes like a dig up or after you
changed location.
In the beginning please set the frequency to the lowest level. 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.
It is recommendable to keep the search coil parallel to the ground while
searching.
It takes some experience to interpret the sounds correctly. The sound
becomes more intense the bigger the object or the closer to the surface the
object is.

4.2.2 Search with 1x1m search frame
Switching on the electronic unit via On-/Off-button.
Select your language.
Select “GOLD ID-XL” as search method.
Perform a zero balance like in 4.2.1
Frame can be carried by either one or two persons.
The search frame is primarily used for the deep sounding after medium sized
and large metal objects. The frame is indispensable for the search in larger
areas.
It is recommendable to keep the search coil parallel and close to the ground
while searching.
Small scrap iron parts will automatically be filtered.
Set frequency like in 4.2.1.

4.3 Battery and charger
The electronic unit is powered by two external
2900mAh Li-Ion batteries, which gets fully
charged each within 90 minutes. (Please note: Do
not exceed the charging time of 90 minutes). The
operating time of the unit depends on the type and
size of the search coil and type of headphones. It
varies between 4 to 6 hours. The charging process
is indicated by a red glowing LED on the power
adapter. The LED changes to green when the
battery is fully charged. Disconnect the adapter
after charging is finished.
An included inverter allows for charging in the car.
