3. Electronic unit
The electronic unit is stored in a hard-wearing box. Besides the display 4 control
elements are located on the front.
The menu knob can be switched to four positions:
ID:
In this search mode the discriminator comes into operation. Thereby an optical and
acoustical discrimination takes place. The various metals are signaled through
differing tones and conductivity values.
AM (all metal mode):
All metals are indicated acoustically and optically through the value number (without
discrimination). The metals are not tested for their conductivity.
This position has the advantage, that you can detect with highest sensibility and
through the value number one can evaluate the object’s depth position. The lower the
value number, the deeper the metal object is hidden. The object’s shape can also be
identified.
BAT:
Scale to control the battery condition. If display shows a value of approx. 100 the
device is fully charged.
OFF: Inoperative
RESET:
Automatic zero balance. By pressing the RESET-button the device is aligned to the
respective ground surface.
FREQ.:
Frequency setting controller –the smaller the item you are searching for, the
smoother the adjustment must be.
VOLUME:
Volume control.

LED:
The optical reference to a metal in the AM and ID mode is shown through the blue
LED. The green LED indicates the frequency pulse.
Back Side:
At the back 3 connection sockets are located:
1. Socket for coils
The connector for the coil is left-hand sided. The plug of the searchcoil has to be
plugged into the socket. Before removing the plug, the jack must be pressed; only
then it is possible to pull out the plug. The connector is compatible with all
searchcoils.
2. Socket for charger
3. Headphone socket
Any commercial headphones with 6.3 mm jack can be plugged. If you use the
headphones, the speaker is turned off. Matching, light-weight headphones are
provided.

4. Search process
Please absolutely note the following:
Avoid conducting overhead lines
Do not use cell phone during operation
Do not carry out measurements during thunderstorms
Protect device from wetness and high humidity
Only a fully charged battery guarantees a trouble-free operation.
For the process or charging only use components provided or released by KTS
GmbH & Co. KG.
To make the search more result-oriented and for this reason successful, the following
facts should be kept in mind:
Change of tone (frequency)
Intensity of tone
Duration of tone
Level of value (display)
A sound modification is the first sign for the existence of a metal object. If it turns out
to be a large object and if it is located near ground surface the intensity of tone will
increase.. While the tone is audible, the searchcoil should be moved in the near
vicinity to detect the possible shape of the metal object.
A simultaneous control of sound and indicated value leads to a better analysis of the
discovered object.
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 activation of the
Reset-button and frequency adjustment.
1. Activate the metal detector with the menu knob. Beforehand the respective
searchcoil has to be cable-connected to the electronic unit.
2. Hold the searchcoil to the ground and press the Reset-button for a brief
moment. Herewith you will 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
searchcoil. This could cause a wrong adjustment and produce unwanted
indicator effects (as the case may be repeat the Reset-procedure at another,
metal-free spot).

3. Initially please set the frequency to the lowest level (turn the Freq.-modulator
counterclockwise). By means of Audio control the volume should be set
audibly. To become acquainted with the handling of the device we generally
recommend to start with the lowest frequency adjustment. With advancing
experience it is expedient, to increase the frequency gradually what will have a
positive effect on the search performance.
Since the function of the Reset-button is decisive, the key should be pressed after
each modification:
1. After every activation 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.
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 your own
search experience should be used for help.
The more intense the sound, the larger the object and the nearer its position to the
surface. While a high search tone is audible, the searchcoil should be moved in the
close surrounding to determine the shape of the metal object.
Note: Please be certain, that there are no metal objects in the close proximity to the metal
detector during zero balance. This can produce a false calibration and unwanted indication
effects.
5. ID Metal Discrimination
Examples for divergent conductivity values:
light metals (e.g. aluminum) approx. 20-50
copper approx. 50-80
gold and precious metal approx. 85 and over.
Please bear in mind that –depending on soil conditions and 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.
Please take not of explanations to error signals on page 12.

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.
6. Installation
The assembly is easy and carried out with a few simple steps:
1. Install the telescope bar by pushing the adjustable carbon tube into the armrest.
2. Connect the telescope bar with the searchcoil and wrap the cable of the coil
around the bar.
3. The electronic unit is placed in a bag; insert the plug of the searchcoil through the
lower opening of the bag in the intended mounting socket.
7. Appropriate handling
Hold the searchcoil approx. 2 to 5 cm parallel to the soil. Due to the pulse induction
method a swivelling of the searchcoil is not necessary.
Determine your own speed during the search. To search a large area without great
expenditure of time we recommend a speedy pace (no jogging).

8. Adjustment
The metal detector PULSE AR III can be adjusted within a very short time.
1. With the menu knob you activate the metal detector. Select the desired sound
volume.
2. Briefly press the Reset-button in order to obtain a zero balance which is
necessary for a failure-free search.
9. Indication of metal
Your device has a sound location system. With the searchcoil’s approach to a metal
object the tone frequency will increase. Once the coil is positioned exactly over the
object, the highest tone is reached.
This method not only helps to locate the exact spot of discovery but it also detects –
based on the duration of the sound –the object’s shape.
Examples:
A long-lasting high tone in longitudinal direction stands for a slim item (e.g. a tube),
a high tone in any direction calls for a circular object.
During the search side noises often prove to be a disturbing factor. Therefore we
recommend the use of the provided headphones, which are switched to Mono, so
that surrounding sounds (for instance traffic or dangerous animals) can be
consciously perceived.
10. Usage of appropriate searchcoils
According to the purpose PULSE AR III is equipped with various searchcoils.
25 cm searchcoil
The 25 cm (10”) searchcoil is the
standard coil of PULSE AR III and
suitable for the search after small metal
objects.

KTS-Electronic GmbH & Co. KG –PULSE AR III
10
45 cm (18”) searchcoil
Very convenient for the search after
small, medium-sized and large metal
objects. Furthermore it has the benefit of
a speedy uninterrupted search process.
Cylindrical coil:
Through its dimensions of 5x20 cm
appropriate for the search in wells,
narrow excavations and underwater. At
the same time it can be helpful to find
micro-objects.
1 x 1 m search frame
Preferably used for the deep sounding after medium-sized and large metal objects.
Furthermore large areas can be scanned fast and comfortable.
During the search you should hold the search frame between 20 to 50 cm over the
soil. A higher distance to the soil reduces the chance of an indication of small and
medium-sized metal objects.

KTS-Electronic GmbH & Co. KG –PULSE AR III

Assembly of the 1 x 1 m search frame
1. Connect the pipes (8 pieces) in numerical order. Please note, that the numbers should
be readable on the upper side.
2. Arrange the search frame on a flat surface and be sure, that the frame is straight.
3. Afterwards the cable has to be placed on the pipe and fixed at the corners with the
provided tape. Please make sure, that cable and search frame are firmly connected to
each other.
Note: Turn off the metal detector in case you want to change the searchcoil, then connect
the selected searchcoil. Please press the Reset-button after you have started the detector
again.
11.Rechargeable battery and charger
Through the mobile Li-Ion quick-charger the
metal detector is fully charged within a very
short time (approx. 90 minutes). Thanks to
the connection possibility at the car
cigarette lighter, this is also possible on the
road.. The charged battery allows an
operating time of approx. 4-8 hours.
An additional inverter module can be used
to charge the battery in the car.

KTS-Electronic GmbH & Co. KG –PULSE AR III
12
Charging process:
1. Attach the battery charger to the connection socket at the backside of the
electronic housing.
2. The red LED indicates the charging process. Please note, that this LED has to be
active during the whole charging time.
3. The maximum charging time is 90 minutes.
4. After the charging process is completed, remove the charging cable plug. The
plug should be pulled out after every charging.
Note: PULSE AR III is equipped with a quick-charger. To prevent damages on the
rechargeable battery always pay absolute attention to the maximum charging time of 90
minutes. Stop the charging process immediately after the battery is fully charged.
Never charge the metal detector without attendance or overnight, resp. over 90 minutes,
because an overcharging can induce damages (e.g. overheating), which leads to the loss of
guaranty.
12. Error signals
In the development of PULSE AR III, special emphasis was placed on stability and
interference immunity so that the search is disturbed as little as possible.
Despite the multitude of filters and modulators it is –to our regret - possible that
certain soil conditions cause disturbances, which can effect your measured values.
Apart from a wrong soil balance adjustment incorrect signals can occur from following
effects.
1. Ferric oxide: Through magnetic ferric oxide soils the conductance of the located
metal can distorted.
2. Adverse effects lead to the fact that large iron metals are indicated as precious
metal.
3. Small parts of bronce partially may be indicated as iron, the definition of the
measured values therefore is only guaranteed starting from 5x5cm in dimension.
4. Because of other metal parts nearby the measured values can be falsified.
5. Strong magnetic interference fields within residential areas and in the proximity of
ground cables can influence the measured values, especially during utilization of
the search frame.
6. Disturbances often occur in the peripherals of radio stations.
7. Strong magnetic fields, particularly in the proximity of high voltage masts, can
cause disfunctions.

13. Care
Your PULSE AR III is easy to clean, yet there are some aspects, which you should
bear in mind, in order to receive the optimal functionality.
Protect the electronic housing with a plastic bag in case you should get caught in
the rain, fog or sandstorm.
Always keep your equipment clean and dry and wipe off sand and dirt.
Note: Avoid extreme temperatures, since it is possible, that electronic elements are
damaged through these circumstances.
Metal detectors produce magnetic fields in the searchcoil and can possibly be
hindered in their operational capability while applied in the closer environment of
certain industrial plants or electronic devices.
