The LORENZ DEEPMAX X5 and X6 seies detectors are
some of the newest developments in the field of Pulse
GBS metal detectors. It is probably one of the most
sensitive and stable metal detecting devices of its kind
presently available. The LORENZ DEEPMAX X5/6 is the
result of many years of research and development. A
lot of efforts have been put into making this new product
and especially in the new improved metal classifications
and automatic ground balancing facilities offered with
the LORENZ DEEPMAX X5 and X6 series.
The Pulse GBS (Pulse Ground Balancing System) is
specialy suitable for searching at depth. The performance
of this electronic device is almost unaffected by salt
water, most types of mineralised grounds or temperature
changes. Specially designed electronics cancel out signals
from the ground. The LORENZ DEEPMAX X5/X6 is
therefore a reliable tool to locate metal objects at great
depths even under the worst environmental conditions.
A new improved circuit design suppresses interference
from power lines and a power pulse technique produces
very accurate signals to obtain very high detection depths.
The LORENZ DEEPMAX X5/X6 is a high quality specialist
Detector and it is designed to be used with both, small
or large coils. Large coils offer extreme depth capabilities
for big metal objects because of the strong and deep
going magnetic field produced. Small coils are preferably
used while searching for small objects like single coins
or gold nuggets.
This model offers a great range on non-ferrous metal
objects in general. A very simple operation is guaranteed
by a specially developed LC Display and a minimum
amount of controls. At the same time this detector model
offers a number of features which are new for a pulse
metal detector. Quality electronics and very special
designed electronic - circuitry produce benefits in terms
of easy of use as well as sensitivity.
The LORENZ DEEPMAX X5/X6 gives a visual indication
on the LC Display for every metal being located. This
time delay reading producing a number between 000
and 099 helps to classify metal objects. The target
classification circuitry is only in some cases affected by
the size of a metal object and therefore identifies small
coins as well as large pieces of metal. The LORENZ
DEEPMAX X5/X6 also offers a sophisticated and refined
ferrous / non- ferrous target analysis which works more
stable on difficult soils in conjunction with the 26cm or
35cm double D search coil. The Detector also emits an
audible sound by way of either a speaker or headphones.
Detection depths achieved (in air tests) are almost the
same in many types of soils and therefore considerably
higher than those possible with standard pulse induction
or sinewave VLF - TR Detectors.
The DEEPMAX metal detectors are often recognised as
representing some of the highest quality and newest
developments in professional metal detecting equipment.
We as a manufacturing company always try to keep the
highest standard on our products, therefore alternations
of the design, specifications as well as the availability
subject to change without notice.
1. Safety information
For reasons of safety it is advisable to read this
operating manual first before turning the Lorenz
DEEPMAX X5/X6 on. Special attention should be paid
to the following notes.
Check out, if the plug-in type charger supplied with
the LORENZ DEEPMAX X5/X6 fits with the AC mains
of your country. The AC plug of the recharger is inter-
changeable and therefore can be used at any countries
mains. See chapter 7 for more detailed information.
The supplied recharger will work at AC voltages of
100-240 V AC (see label).
Damaged connecting cables or search coils should
no longer be used, because of possible electrical
shock.
To avoid short circuits, wrong polarity or electrical
shock only spare parts and accessories offered by the
manufacturer of the LORENZ DEEPMAX X5/X6 should
be used.
When digging for metal objects war material could
also be found. Precautions should be taken in advance
especially when big objects have been located.
Special kinds of mines could be triggered by the
strong DC magnetic field produced by the search
coil. Special versions for military use are also available
on request. Persons with implanted pacemaker or
other sensitive device should not approach to the
field of the search coil. Please understand that we as
the manufacturer of the LORENZ DEEPMAX X5/X6
can not be made liable for any kind of damage caused
by or in conjunction with our products.

The LORENZ DEEPMAX X5/X6 is based on the non-
motion; Pulse GBS (Pulse Ground Balancing System).
Short and intensive magnetic pulses are emitted by
means of a search coil first. Those magnetic pulses
produce eddy currents in conducting materials like metal
objects for example. Said eddy currents will be kept in
a metal object and will die away after the magnetic pulse
emitted by the search coil has turned off. This is the
reason why it is possible to detect those eddy currents
during the time delayed receiving phase by means of
the same search coil which now acts as a receiving coil.
A rather complicated electronic circuitry is necessary to
detect those tiny voltage changes and has to separate
that particular signal from interference also received.
The signal has to be amplified to drive a voltage controlled
oscillator (VCO), which emits an audible signal either
by headphones or built-in loudspeaker when a metal is
in the near of the field of the search coil.
Eddy currents produced in a metal object by means of
a pulsed primary field, will die away differently depending
on the conductivity of the metal object. The classification
circuit therefore gives a visual time delay reading for the
eddy currents received over a certain period of time. In
addition a ferrous / non- ferrous indication for every
metal being detected is working when a double D coil
is in use. This gives further information on the probable
kind of metal being located as well as the audio sound
emitted, which makes it easy to predetermine the exact
place and the size of the buried metal object.
2.1. Advantages
The Pulse GBS principle has got the advantage of
using large diameter coils and high transmitting power.
This is especially necessary when searching at depth.
Frame mounted cable coils of different size and shape
can be connected to the LORENZ DEEPMAX X5/X6
without any adjustments.
A special adaptation circuit has been added to the
Detector to suit with different coil systems
automatically. This ensures extreme depth capabilities
with any coil connected. When enlarging the search
coil diameter the sensitivity to bigger objects will also
rise. At the same time smaller objects will be located
less sensitive. This is particularly desirable when
locating large objects while ignoring small bits. Large
coils offer very high detection ranges. Even in difficult
soils where magnetic iron oxides are present the
LORENZ DEEPMAX X5/X6 will offer extreme depth capabilities
for both ferrous and non-ferrous metal objects when the
Ground Balancing System is in use. Other systems often
suffer from ground effects which reduce the depth range
in the ground. The LORENZ DEEPMAX X5/X6 will be able
to locate objects at almost the same depths either in most
types of ground or ”in air tests”. The high sensitivity of the
LORENZ DEEPMAX X5/X6 to non- ferrous metal objects
like gold, silver and copper together with the new target
analysis make this detector an outstanding device for many
different locating purposes.
The LORENZ DEEPMAX X5/X6 was developed to provide
a number of features including high sensitivity and stability
together with easy operation. The amount of controls was
therefore reduced and a calibration of the Detector to our
factory settings was also made to guarantee best results in
the field:

2.2. Applications
The LORENZ DEEPMAX X5/X6 was developed for
professional search and locating applications.
A variety of search coils can be connected to this
metal detector. Large areas can be detected
effectively especially with frame coils. Saltwater,
most types of ground or temperature changes will
only slightly affect the detection range of the
LORENZ DEEPMAX X5/X6. It is possible to eliminate
some unwanted objects like nails and foils or to
identify them as being small unwanted objects
while searching for bigger and deeper objects. In
conjunction with small coils the LORENZ DEEPMAX
X5/X6 is a great tool when searching for small
objects deep in the ground.

The front panel controls of the two detectors X5 and X6
are the same, namely three push buttons with ZERO,
GB Ground Balance, and POWER function and two
incremental encoders with push button for MENU and
SELECT. The X6 offers an additional data logger function
which can also be set by means of ZERO and GB
controls when the data logger function is turned on.
POWER button turns on and off the unit. A connected
and fully charged battery pack and a search coil will be
essential while doing this. The electronics runs through
a tuning and self checking sequence with all the icons
coming on first.
ZERO button retunes the electronics within half a
second.
The ZERO button is the most important control as the
whole electronics, including the discriminator and the
audio will be retuned when pressing this control.
When turning the detector on with the POWER button,
the electronics will automatically retune itself.
This ZERO button has to be pressed frequently to
retune the electronics to the set audio and visual
indications. When doing this simply raise the coil to
the air, far away from any metal objects and the detector
itself and press this button shortly. An ARROW and
COIL icon will come on the display. Rather keep the
coil horizontally to minimize the effects of interference
induction in the coil. There should be almost no signal
indication on the intensity bar graph after having done
this. The small arrow shows the starting point of the
bar graph. Afterwards you can lower the coil to the
ground again. Please be aware that the detector consists
of quite a few metal parts and therefore can indicate
itself. When the data logger function of the X6 is selected
this button also acts as a start and stop button when
taking field data with each track.
GB Ground Balance button will activate an automatic
two step tuning process of the detector to the present
ground conditions:
1. Before starting this process hold the coil horizontally 
in the air away from any metal.
2. Press the GB button and don’t move the coil while 
looking on the display and watching an Arrow 
pointing up with a COIL icon coming on and several 
high beep sounds indicating that the first tuning 
process is active.
3. Afterwards the arrow is pointing downwards, 
indicating that the coil should be lowered to the 
soil without any movements at a place with no 
metal around.
4. Simply push the same GB button again to activate 
the second tuning process while holding the coil 
close to the ground and listen for low  frequency 
beep sounds. The arrow will disappear when this 
tuning process is completed. Afterwards there should 
be no or only weak signals from the ground when 
moving the coil up and downwards when a 
GROUND 1,2,3… setting is selected.
During operation the ground setting of the detector
can also be altered by the way of the G1 and G2
control manually.
In general an automatic tuning process with GB
control should be taken first.
When the data logger is active (only X6- version) this
GB button also acts as a field data storing or track
deleting control.

MENU G1 / SELECT G2 Incremental encoders act
as rotary switches to select different functions and settings
of the detector:
1. To open a menu press the MENU control for one 
second until a function icon starts to flash on the 
display.
2. Rotate the same control to choose the operation 
mode you want to change. The active icon keeps 
flashing.
3. Rotate the SELECT control until the desired number 
is selected and alter the parameter, for example a 
low number stands for a low setting, high numbers 
will result in a higher setting.
4. Press any of the Incremental encoders or the ZERO 
button shortly to leave the menu and go on searching 
afterwards.
During operation, when the menu is not active, the same
controls will adjust the settings of the Ground Balance
circuit, namely GND1 and GND2 which will also be
displayed with a number 000-999 and corresponding
G1 / G2 icon.
Note: It is necessary to Ground Balance the unit
automatically with the GB button first before starting
to alter ground balance parameters or using a target
identification.
Display
The Deepmax X5/X6 offers a huge number of functions
which are shown on a large LC Display all the time even
while searching. To select a function or alter parameters
refer to the MENU / SELECT controls. The lower part of
the Display shows the different functions and parameters
as the upper part indicates more information on the
probable kind of metal, signal intensity, ground balance
settings, indications for the proper use of the automatic
ground balance or the data logger function as well as
battery condition.
Functions/ Parameters
DEL Delay settings 1-4 offer different sensitivity range
on different metals without excluding ground effects. 1
gives the highest sensitivity range on small and thin non-
ferrous metal objects as 4 offers a poor sensitivity range
on these small bits and pieces but still a good range on
larger metal objects. The Delay function is mainly in use
while searching with large frame coils on soils with low
iron oxide content. In most cases the coil has to be kept
at a certain distance and at constant height over the
ground to avoid false signals from the ground.
GND compensates heavily mineralised soils containing
plenty of magnetic iron oxides.
Single hot stones or certain iron objects can also be
completely eliminated/ canceled by the way of this
function. Ground settings 1-3 and 4 (only with DD-
coils) will activate different ground canceling settings to
ignore the ground. The ground settings work differently
with the different coils (small, frame, DD). Therefore
please refer to the following table to select the right
setting for your detection purpose.
SENS Sensitivity range from 1 lowest sensitivity to 5
highest sensitivity setting
FREQ With this function the preset operation frequency
of the LORENZ DEEPMAX X5/X6 can be altered. This is
mainly necessary when searching near power lines,
which cause low frequency interference. The performance
of the detector won’t be affected by changing the position
of this control, but the amount of interference can be
greatly reduced by doing this.
Frequency range from 1 lowest to 9 highest operating
frequency. In general this setting does not affect the
electronics and therefore can be left in any position. To
reduce interferences please also refer to our double
frame coil kits to make operation in urban areas possible.
FILTER range from 0 filter off to 5 highest filter setting
to reduce intermittent or pulsed false signals from
inducing power lines or radio transmitters. The response
speed is reduced with higher filter settings, therefore
higher settings are only usefull with large frame coils.
VOLUME 0 turns off the built-in Loudspeaker or
external Headphones 9 highest setting is very loud.
AUDIO With this audio function the tick-rate of the
audio can be selected. The initial tick-rate can be altered
from silent to a low frequency ticking tone. When put
to the 0 setting the built- in loudspeaker will give one
tick every 1- 2 seconds, after the detector has been
retuned with the ZERO button.
The threshold ranges from -9 silent, 0 slow ticking sound
to +9 fast ticking sound. This setting can always be
recalled by pressing ZERO. For most applications a
setting between 0 and +2 is perfect.

AUTO self adjusting threshold cancels out the effects of
drift which could occur during the first minutes of operation
and when temperature changes are present such as sunlight
warming up the coil and therefore alters the electrical
properties. In most cases the detector will work in position
0 as a non motion metal detector perfectly. However in
some cases especially when selecting GND 2 with a DD
coil a low AUTO setting will make the unit work more
stable. Therefore the ZERO button has no longer to be
pressed so frequently. The range starts with 1 very slow self
adjusting to 5 very fast automatic self adjusting Motion
detector. A slow moving speed of the searchcoil over the
ground or target has to be provided to find metals. While
resting over the object the audio and meter indication
disappears. Rather turn off 0 the AUTO function while
using a frame coil in order not to lose too much sensitivity.
DLOG (this function is only available with DEEPMAX X6)
0= turned off, 1= turns on the built-in data logger function
and starts a different display setting with preset functions.
Therefore only FREQ, VOLUME, DLOG and LIGHT can
be adjusted. In addition MMeter length of a track in meters,
TR Track number, FI Field number, HDG Heading for each
track will be available for selection with the MENU/ SELECT
controls as shown before.
1. To start collecting field data first connect the GPS module
with USB stick and the Detector itself. The USB module has
to be mounted on the shoulder of the operator with the
transparent part pointing up. Connect a search coil (frame
coil) and battery pack, turn on the unit and make sure that
the data logger DLOG is turned off DLOG 0.
2. Hold the frame coil in the air, far away from any metal.
Push the GB Ground button once and wait until the high
beep sounds are completed. Lower the frame coil to the
ground at a distance of approximately 10cm over the ground
and press the same GB button a second time and wait
until the lower beep sounds indicate that the tuning process
is in progress and completed.
3. Press the MENU control for approximately 1 second to
start the menu. Select DLOG 1, Mfor meter indications,
FREQ (any position that looks silent on the bar graph)
VOLUME (adjust to desired setting) and leave the menu
by pressing MENU/ SELECT or ZERO.
4. Check the icons for the field, antenna and USB coming
on. Flashing antenna means no valid GPS data available.
Flashing USB means problem occurred with storing data.
5. Start collecting field data in the left corner of the new
field by pressing the ZERO button and immediately start
walking a straight line at constant speed. The large arrow
starts to move to indicate that data acquisition is working.
A pulsed beep sound indicates the same. As the MMeter
indication is selected the multi function display shows the
lenght of the track in meters already being covered. In that
case walk a few meters on each track until a useful indication
can be read on the display.
6. Stop the first Track by pressing the ZERO button again.
A low and high beep sound states that the first track is
completed.
7. Move to the next track for example 1m to the side and
180 degrees pointing backwards. Start and stop with the
next track the same way as the previous track, pressing the
ZERO button. A +/-180 degrees indication comes on to
make sure that you move backwards. The multi function
display counts the meters you walk back until you reach
the starting X line with 0 meters again.
8. A compass indication in the middle of the display points
to the direction you have to walk. For example two square
icons pointing to the right show that you are presently not
walking in a straight and parallel line and that you have to
move slightly to the right while walking until the square
icons disappear. In addition the present Heading can be
indicated on the multi function display when HDG is
selected. Therefore simply make sure that the same Number
appears when you walk on each track. A few meters have
to be covered until an indication is possible.
9. At the end of the field push the GB/ field button once
and a longer lower beep sound states that the first field is
completed and stored on the USB stick. The next field will
automatically come on with a higher number when you
start collecting data again.
10.Disconnect the USB Stick from the GPS module and
read the data with your computer with installed Scripter
and Surfer software.
In order to change from MMeter to TR Track, FI Field,
HDG Heading indication simply alter the SELECT rotary
control. This can be performed even during the operation
of the Deepmax X6. When starting with the first track there
will be no HDG Heading available as this track is for reference
purposes only.
LIGHT adjusts the backlight from 0 off to 9 bright
TONE function changes from Analog A signal to Logarithmic
L signal range providing a different dynamic range of the audio
and intensity bar graph in the middle of the display. In the
Analog mode the audio frequency raises quickly to its highest
tone. In the Logarithmic mode the tone will raise quickly in the
beginning and than gradually to the highest tone even if the
metal object is close to the coil for better pinpointing.
Target Identification
The Deepmax X5/ X6 series detectors offer two different
target identifications namely a FE Ferrous/ NON-FE
Non-Ferrous indication which is only working when a DD
coil is connected and a time delay reading of the eddy
currents produced in conducting materials like metals
which works with any coil connected. Both indications
give a hint on the probable kind of metal being detected.
Please find a table of different metals and there
corresponding numbers being taken. The FE/ NON-FE
indication is based on a motion circuit, therefore

000-099 TIME DELAY reading
A time delay reading which is mainly derived from the
conductivity, permeability and the object’s size is displayed
with a specific number on the LC Display. Possible
examples:
(000-020 coin or piece of foil, 030-060 iron, 060-099
large copper or silver object)
The indication is displayed as long as the coil is over the
target.
Any metal object detected will give a specific number
(000 to 099). Therefore a certain intensity of the target
signal is necessary for a time delay reading. The number
simply appears when a reading was possible. The
indication will be stored as long as the search coil is over
the target and turns off when the search coil passes the
target.
FERROUS / NON-FERROUS icons
This function does only work with the 26cm or 35cm
double D coil. Ferrous metal objects like iron for example
produce a FE indication at the top of the display and
Non-ferrous metal objects like gold silver or copper will
result in a NON- FE icon indication when the searchcoil
is moved over the target. The two icons will turn off if
no metal is present or no double D coil is connected.
This identification facility is tuned to the ground with the
GB automatic ground balance.
INTENSITY / signal intensity bar graph icons
The signal strength will be indicated by the way of a
large bar graph in the middle of the LC Display and an
audio response from the speaker or headphones.
ARROW; AERIAL, USB icons
These icons will work together with the built- in datalogger
function which will run on a hard- and software which
comes with the X6 version. For further information please
refer to the instructions for use the LORENZ DEEPMAX
X6, six channel datalogger, Sufer and Scripter Software..
BATTERY icon
The battery condition will be displayed on the bar graph
with 5 bars located on the top of the display. Note: The
battery condition should be checked with a search coil
connected and after a few minuts of operation.
BATTERY alarm LOW BAT
Low battery condition will be indicated by a pulsed beep
sound every few seconds the LORENZ DEEPMAX X5/X6
has to be turned off when this sound appears to avoid
damage from the batteries. The pulse circuit is
automatically turned off at low battery for safety reasons.
BATTERY jack
This jack is located on the bottom of the control housing.
The plug of the supplied battery pack has to be connected
with this jack. The operation time of the LORENZ
DEEPMAX X5/X6 on a fully charged battery pack at
normal temperature range is approximately 5 to 10 hours
depending on the coil connected.
COIL jack
Search coils of different size and shape can be connected
to this jack. The search coils available for the LORENZ
DEEPMAX X5/X6 have got coded connectors to adapt
the electronics to the coil automatically. To connect a
coil plug to the electronics make sure that the plug is
fully pushed in the jack and that the sleeve is fastened
by rotating it clockwise.
Note: Any connectors should be disconnected when
planning to store the LORENZ DEEPMAX X5/X6.
HEADPHONE- jack
The supplied stereo headphones can be connected to this
jack. Any stereo headphones with 1/4 inch (6,35 mm)
stereo plugs can be connected to the LORENZ DEEPMAX
X5/X6 without any problems. The built- in loudspeaker will
be automatically turned off when headphones are connected.
Note: Special headphone-adapter plugs have to be
disconnected when using the loudspeaker.
Loudspeaker
The LORENZ DEEPMAX X5/X6 has got a built-in loud-
speaker on the front which gives an audible signal when
the search coil approaches to a metal object. The audio
frequency will change with the distance between the search
coil and target for better pinpointing. Especially with two
persons operation and large diameter coils the signal from
the loudspeaker is of greate help for both persons.
the coil has to be moved over the metal object to achieve
an indication. The Number for the time delay
measurement is static and will come on when certain
intensity is reached and stays on as long as the coil is
over the target.

Do connect the two shoulder straps to the main belt at
both sides in the front and one large strap above the
battery pack on the back. Adjust all the belts to
comfortable length and fasten the main electronics unit
in front of the operator.
Connect the search coil-connector to the COIL jack on
the right hand side of the electronics unit, and fasten
the plastic sleeve of the connector by rotating it clockwise.
Do connect the battery connector to the BATTERY jack
which is located on the left side of the detector by
pushing it gently. Hold the connected searchcoil
horizontaly and far away from metal objects about one
meter above the ground. Set the POWER button to
turn the LORENZ DEEPMAX X5/X6 on. Press again for
“OFF”. At switch ON the detector runs through a display
check sequence since all the icons com on and indicate
the retuning process is performed by the electronics at
the same time. If the LOW BAT icon displays less than
one bar afterwards or if the BATTERY alarm gives a
beep sound every few seconds, the detector should be
turned off again and the battery should immediately be
recharged with the supplied charger. The battery condition
is displayed with five bars on the top of the Display
continuously during operation.
Note: On the main electronics unit three large aluminium
plates are located, of which two get warm during
operation. Please make sure that the heat can disappear
and that the aluminium plates are not covered with a
jacket or other materials to avoid overheating the unit
or burn your skin. The unit therefore has to be looked
after during operation and should not be used in sealed
containers.
Afterwards the Detector will automatically turn to the
positions which were selected the last time the detector
was in use. While pushing and rotating the ZERO, GB,
MENU, SELECT push buttons and encoders, different
settings will be selected and will be displayed on the
bottom of the LC Display at the same time. To enter the
menu and to change a parameter go on as follows. Press
the MENU encoder for one second until one icon starts
to flash, than rotate the MENU encoder, avoiding to
push it again to find the desired function to be changed.
Use the second encoder SELECT and rotate until the
new parameter is set. To leave the MENU press either
the MENU, SELECT or ZERO button shortly afterwards.
For the first time adjust the detector as follows:
Connect a 35cm DD coil and select GND 2, SENS 3,
FREQ 9, FILTER 2,VOLUME 7, AUDIO+1, AUTO 0,
DLOG 0, LIGHT9, TONE L. Leave the menu and hold
the coil in the air. Before metal detecting ground
balance the detector first. Press the GB button while
holding the coil in the air and wait until the arrow
changes from up to down on the display and the high
beep sounds are heard. Lower the coil to the ground
at a place with no metal and repeat pushing the GB
button. The second step of the automatic ground
balance is activated and indicated by the way of the
arrow and lower beep sounds. When the arrow
disappears the tuning process is completed and you
can move the coil upwards and downwards without
hearing any changes in the audio ticking tone.The
detector is ready for operation afterwards. If low mineral
contents of the ground are expected it is sufficient to
work in the DEL 1 mode instead of a GND
groundexcluding mode. Therefore hold the searchcoil
a few centimeters over the ground while simultaneously
pressing the ZERO button shortly. Than try to keep
the distance between the coil and the ground very
constant when searching. The DELAY Modes are often
in use with frame coils on weakly mineralized soils and
a distance of approximately 50cm between the coil
and the ground are kept constant.
The selected audio ticking sound is audible every
second. Alter the AUDIO control for different ticking
sound if necessary.
Important note: With every retuning process one should
pay attention that no metal is in the near of the search
coil while pressing the ZERO button. It is therefore
necessary to hold the search coil far away from metal
objects and the electronics control box itself.
4. Operating procedures I
USB Jack Version X5
In order to update the firmware of the Deepmax X5 the
supplied USB- Stick can be used to flash the built- in
controllers by the way of using the newest software
version. It will take a few minutes to transfer the data.
For furthe details please refer to instructious on our
website www.metaldetectors.de
GPS Module Jack Version X6
The LORENZ DEEPMAX X6 has a built-in data logger
function in order to record different signal data during
operation. For operation a supplied hard- and software
kit will be necessary. To this jack the combined GPS
module with USB stick can be connected for further
data acquisition. In conjunction with available specially
developed software it is possible to convert stored data
to visual 2 D image or 3 D surface maps on a computer
for example.
