Dierent search coils can be connected to the
LORENZ DEEPMAX Z2 for special search and loca-
tion purposes. In general, small search coils oer
great detection depths on small metal objects while
large search coils oer the highest possible detec-
tion depths on big objects. The possible detection
depths also depend on the setting of the detector,
the kind of metal and the shape of the metal object
and slightly on the type of ground below the search
coil. The low sensitivity for small metal pieces in
conjunction with the very high sensitivity for bigger
and deeper metal objects make the DEEPMAX Z2
especially useful when using it with large frame
mounted search coils. The maximum detection
depths achievable with a 1m x 1m frame mounted
search coil are very high and can be increased when
enlarging the search coil to 1,5 m x 1,5 m, 2 m x
2 m or 3 m x 3 m. In that case it will no longer be
possible to detect single coins or small nails with
those very large frame mounted search coils. In
this chapter dierent search coils available with the
LORENZ DEEPMAX Z2 are described. (Please refer to
chapter 11 for detection depths)
26 CM SEARCH COIL
This search coil was mainly developed for the loca-
tion of very small metal objects like small nuggets
or coin sized metal objects for example. The maxi-
mum detection depth is limited by the object size
and the coil. In some cases it is easier to pinpoint
very small metal fragments with this coil rather than
with a double D- coil.
This search coil can be useful while pinpointing
large metal objects which have been located with
a frame mounted search coil before. Deeply buried
metal objects can be out of the range of the small
26 cm search coil and therefore can only be detec-
ted with frame mounted search coils. The 26 cm
search coil is waterproof and therefore can be used
in saltwater for example.
