UNIVERSAL CABLE COIL 8 M PERIMETER
This extremely lightweight and easy to transport
universal cable oers a variety of dierent search
coils for dierent search applications. The cable
coil has to be xed with tape on a frame which can
be made of PVC-tubes for example. The following
search coil congurations are mainly useful for the
location of metal objects with a surface of at least
6cm x 6cm or hand sized metal objects for example.
Small metal pieces like single coins or nails will be
indicated with poor sensitivity or will even be eli-
minated in some cases because they are out of the
range of these frame coils. It is very easy to cover
a large area with frame coils in a short time. This is
especially useful when looking for bigger deeply
buried metal objects while ignoring those smaller
metal pieces at the surface.
The following frame mounted search coils have to
be carried by two persons with adjustable carrying
straps. The search coil should be hold in parallel to
the ground at a constant distance of 10 to 60 cm. In
order to avoid false signals the electronics control
box or additional power bank should always be
carried far away from the eld of the search coil.
It is also necessary not to wear any belts or shoes
with metal content when working with the LORENZ
DEEPMAX Z2.
0,67 M X 0,67 M (3 WINDINGS)
UNIVERSAL CABLE COIL 8 M PERIMETER
The 8m universal cable coil has to be arranged to a 3
winding search coil and has to be xed on a 0,67 m x
0,67 m frame made of PVC-tubes for example. Never
use any metal screws for the construction of a frame!
This is the smallest frame mounted search coil which
oers extreme detection depths for smaller and me-
dium sized objects. Metal fragments and some coins
will still be indicated.
1 M X 1 M (2 WINDINGS) UNIVERSAL
CABLE COIL 8 M PERIMETER
The universal cable coil has to be arranged to a 2
winding search coil and has to be xed on a 1 m x 1
m PVC- tube frame for example. Searching with the 1
m x 1 m frame coil is mainly advisable when looking
for hand sized or bigger metal objects buried deep
while ignoring small coins, nails and pieces of foil at
the surface of the ground. The possible detection
depths with this particular frame coil are very high
compared with standard sine wave VLF-TR-detectors
(see chapter 11). This is one of the reasons why this
particular search coil is used for most professional
applications. Large areas can be covered in a short
time. Best results are achieved with metal objects
having a surface of at least 10 cm x 10 cm. Because of
the size of the coil most of the small metal fragments
will be ignored. However bigger nails can be identi-
ed with the conductivity/ time delay metal iden-
tication. Most of the smaller nails and other metal
fragments can be easily eliminated by increasing the
distance between the search coil and the ground.
Even at distances of 50 cm or more there will only
be negligible detection depth losses when locating
large metal objects.
This frame coil has to be carried by two persons with
carrying straps.
The high depth range of the 1 m x 1 m frame coil is
achieved with intense and therefore deep going ma-
gnetic eld transmitted. For even higher detection
depths use the 12 m cable coil which can be arran-
ged to 1,5 m x 1,5 m or even 3 m x 3 m frames.
