Pulse Induction Metal Detector
Ground Pioneer
4500
help the users to find
deeper and easily
the location of the detected metal

The Ground Pioneer 4500 is the pulse metal detector with great power plus all the
major advancements of our previous discriminating pulse induction metal detectors.
The DIGITAL Ground Pioneer 4500 is a composite detector not only for the reason
that there is a build-in MAGNETOMETER SENSOR SYSTEM but also by reason
of that there is provided RS 232 PORT for connection to computer and GPS system
for localizing and visualization of the burried object.
The Digital Ground Pioneer 4500 is designed for detecting deeply buried or lost
metal objects metal pipes unterground communication equipment treasures and
similar objects and can easily detect larger objects buried up to 8 m deep because the
unit works by the principle of electromagnetic induction at a very low
frequency which allows penetration deeply in the ground.
So the Digital Ground Pioneer
4500 is good choice not only
for the treasure hunters but
also for archaeological
detection and geophysical
prospecting.
Target identification and
discrimination by Ground
Pioneer 4500 is possible with
the 1/1 SQUARE SEARCH
COIL(BASIC) embedded in
PVC tubes:
–1 -

But search coils with sizes 0,5/0,5m; 1,5/1,5m and 2/2m also can be connected to the
unit.Please note – all these coils have build-in Magnetometer Sensor System.
This helps you to discriminate out
what targets are ferrous.
With larger diameter coil even big
areas can be searched quickly.
With very large search coils
Ground Pioneer 4500 penetrates
deeper than it is usually possible
with smaller coils.
With the large search coils the
very small metal pieces are
ignored automatically !!!

Why for this test we have used 1/1 m search coil? The concentrated magnetic field of
this coil allows an excellent detection range on relatively small metal objects.Targets
the size of a cash box are clearly detected from a distances of 7 feet.

The square search coils with
size 1/1 m; 1 5/1 5 m; 2/2 m
can be assembled for use or
dismantled for transportation
easily and quickly.
Note! Only the 0 50/0 50 m
search coil in PVC tube can
not be dismantled.
Searching with large search
coils ( 1 m and large) is
easy when the coil is carried
by two people with the help of supplied straps.The search coil should be held
approximately 10 to 20 cm. from the ground while searching.
The pinpoiting of the burried object with Ground Pioneer 4500 can be achieved with
area of ROUND SEARCH COIL:

5” SEARCH COIL
11” SEARCH COIL
15” SEARCH COIL
What round search coil to choose when you purchase Ground Pioneer4500? This is
the most popular question.It is well known that the larger searchcoils give better
depth for larger targets and better ground coverage. But the sensitivity to smaller
objects may be sacrificed. The smaller search coils offer greater sensitivity to smaller
objects and improved target separation in trashy areas.
An alternative search coil for Ground
Pioneer4500 is the CABLE COIL with
size 2/2 m.We gave this search coil the
name “universal” because she can
work with all our pulse induction

detectors independently of this whether or not they are discriminating detectors. Also
this search coil offers FI E more ARRANGEMENTS to suit your search
needs.This search coil can be arranged as 0 50/0 50; 1/1 m; 1/3 m and 2/2m coils by
fastening the windings on free frame ( from PVC for example ) with tape. It can also
be arranged in form as ”eight”.Why we recommend this coil when you purchase
Ground Pioneer4500? With this coil we have registered 15% AND MORE
DEPTH for big objects by its test in comparision with the standart square search
coils. But Note!!! This coil is UNDISCRIMINATING.

FUNCTIONAL FIELDS OF LCD DISPLAY:
1. INDICATOR FOR THE BATTERY CONDITION.
It is recommended that the supply of the storage battery to be done before the
indicator shows a completely dead battery.
Ground Pioneer 4500 comes to you in version with an external accumulator
system for its switching in the device.The supply system and the battery
are integrated in this system ( including the supply from an automobile
accumulator).
The battery of Ground Pioneer 4500 is rechargeable 1 3(2 3-optional)Ah
hermetic acid Battery and allows premature supply not affecting its work.
The battery charging time ( for empty battery ) is max.10 hours.
The battery supplied with your detector comes in charged condition.
It is not necessary to charge the system before the first time you start work
with Ground Pioneer 4500. But we recommend checking its
condition and when low battery condition is indicated you should immediately
recharge the battery.
Please Note: the external accumulator system could not be charged from the
unit.
2. INDICATION FOR THE DISCRIMINATION REGIME.
Ground Pioneer 4500 can work in two regimes of discrimination – with or
without sound discrimination.
In this field it is indicated which of these two regimes you may chooce for the
work.
This symbor appears when you are in
regime with sound discrimination
And this - when you will work in regime
without sound discrimination
Note!!! The microprocessor “remembers” the condition of the device when it is
switching off.

3. INDICATOR OF THE REGIME OF AUTOTUNING TO THE SOIL
CONDITIONS:
When in field (3) appears symbol AUTO you are in regime for constant
setting up to the soil changes and autoreset after every registrated object by the
device .
When in field (3) appears symbol SEMI you are in semiautomatic
regime.Handset to the changes in the soil and autoreset after every registrared
object.
Note!!! The microprocessor “remembers” the condition of the device when it is
switching off
4. INDICATOR OF THE INTENSITY OF THE SIGNAL.
5. INDICATOR FOR THE KIND OF THE METAL.
When the unit indicate ferrous object appears the Symbol
in the field (5).
This indicator is undependent from the condition of filed (2) – that is to say-
undependent from this if you work in regime with or without sound
discrimination the symbol Fe appears when ferrous object is indicated.
FUNCTIONAL BUTTONS OF FRONT PANEL AND HOW TO WORK
WITH THEM
SWITCH ON BUTTON
Five seconds after pressing this button on the display appears the
greeting logo and the device is ready for work:
- 9 -

After that you can choose between two different graph regimes.When the device is
switched on implicitly it is in a regime LE EL MODE:
It shows the battery condition and current settings of Ground Pioneer 4500.Because
this pulse induction detector is designed to memory the last settings the
microprocessor “remembers” the condition of the device when it is switching off.
Pressing the button you choose the regime GRAPH MODE for your
device:
Now you can choose the suitable parameters for work with the detector.The functions
SENSITI ITY, DELAY and THRESHOLD are controlled from the button
of the device.
The SENSITI ITY level alters how responsive the detector is to signals
received from the search coil.The higher the Sensitivity level the more
responsive the detector.With FIRST PRESS on the button appears the
symbol SENSE on the LCD display.The Sensitivity values are only
- 10 -

adjustable in the range 0-15:
By pressing or buttons you can increase or decrease
the values of the Sensitivity. Heavy ground mineralization nearby radio stations or
power transformers are reasons to lower the value of Sensitivity.
By SECOND PRESSING on the button SDT the symbol DELAY appears on the
LCD display:
As by Sensitivity control by pressing on the two buttons on the left side of the Front
panel you can increase or decrease the values.The Delay values are also adjustable in
the range 0-15. For beaches and very light soil minerals you can choose the low
value for the Delay.For standart or general operating conditions – middle values.
When you work in heavy mineral ground or when you search very deep and large
targets you can choose high values.
By THIRD PRESSING the symbol THRESHOLD appears on the LCD display:
The values are also adjustable in the range 0-15.The SOUND THRESHOLD is
used to ground balance the detector.By heavy mineral ground you use the low levels.
- 11 -

By FOURTH PRESS on SDT button you go out from the regime “setting-up” and
the symbol PLEASE WAIT appears on the display:
Five seconds after its disappearance the work with the device can go on.
As we mentionted before Ground Pioneer 4500 can work in two regimes of
discrimination – with or without SOUND DISCRIMINATION.You can chooce
these regimes by pressing on button. Independently of whether you
work in regime with or without sound discrimination the symbol Fe appears when
ferrous object is indicated.
Another button on the display of Ground Pioneer4500 is the button for
the choice of search regimes – AUTO or SEMIAUTO.Automatic mode is
motion detection.The search coil needs to be moved completely through the
target area.The Ground Pioneer 4500 retunes automatically of the ground
conditions(mineralization).
Semiauto is “no motion” regime.The setting-up is done by button
RES.
Button to RESET control unit in new ground conditions.Depressing
button one or more times is needed in each new targer area or if any other
settings are changed. Pressing reset over metal will ignore similar metal
targets.The unit needs to be reset over a clear area ( not on targets) not
including minerals in ground.After pressing the Reset button appears the symbol
“Please wait”:
Five seconds after its disappearance the work with the device can go on.
- 12 -

LIGHT button of LCD display.It works in three regimes.You can
choose any of these three regimes by pressing the button.
AUTO – The device is started always at this rate:
After pressing any functional button the light appears in five seconds.
OFF - The light is constantly switched off:
ON - The light is constantly switched on:
When you choose this regime you must not forget that the voltage of the
batteries will decrease quickly.
After pressing this button for a few seconds sound signal is heard and the
sign “shutdown” appears:
And then the device turns off.
