- DEEPMAX Z1
The LORENZ DEEPMAX Z1 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.
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.
rather complicated electronic circuitry
is necessary to detect those
tiny voltage changes and has to separate
particular signal from interference
also received. The signal
has to be amplified to drive an audio stage
with voltage controlled oscillator (VCO),
an audible signal either by headphones or
built-in loudspeaker when a metal is
in the near of the
field of the search coil.>br>

by means of a pulsed primary field, will

addition a ferrous/ non- ferrous indication
is working when a double D coil is in
use. This gives further information on the probable
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.
The Pulse GBS principle has got the advantage
of using large diameter coils and high
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
Z1 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.
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
Z1 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
LORENZ DEEPMAX Z1 will be able to locate
objects at almost the same depths either
in most types of ground or ”in air tests”.
high sensitivity of the DEEPMAX Z1 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.

as large pieces
LORENZ DEEPMAX Z1 also offers a sophisticated

which works more stable on difficult soils
in conjunction with the 26cm or 35cm double
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 sine wave VLF - TR Detectors.
The LORENZ DEEPMAX Z1 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
especially with frame coils. Saltwater, most
types of ground or temperature changes will only
affect the detection range of the DEEPMAX Z1.

objects like nails and foils or to identify
them as being
small unwanted objects while searching for
bigger and deeper objects. In conjunction
the DEEPMAX Z1 is a great tool when searching
for small objects deep in the ground.
