User's Manual

Note: The electrical properties of the double D

search coils may change when mechanical tension

or high temperature is put on the coil when being

used or stored not properly. The same with the

connecting cable which should be fastened with the

belt strap rst before connecting it to the electronics

unit to protect the same and to avoid broken cables.

44CM SEARCH COIL

This search coil can be operated by a single person

with the telescopic-S-rod-handle. It oers extre-

me depth ranges on either single coins or bigger

objects buried deep in the ground. Depth ranges

of more than 1 m for a metal object of the size of a

soft drink can (0,33 l) or more than 50 cm on a sin-

gle gold coin with 25 mm diameter make this coil

interesting for a lot of dierent search and locating

purposes.

Those extreme depth ranges on medium sized and

bigger metal objects make frame mounted search

coils unnecessary in some cases. Small items can be

eliminated by increasing the distance between the

coil and the ground. This 44 cm coil is more e-

cient as it covers much more ground than a 26cm

coil does. Coins with a diameter of less than 15mm

should rather be detected with smaller search coils.

1 M X 1 M FRAME COIL WITH

CABLE MOUNTED ON TUBES

This is a very user friendly 1 m x 1 m coil with the

same electrical properties as the 8 m universal

cable coil with two windings as described below.

The main advantage of this particular search coil is

its low weight and simple assembly, which can be

performed in a few steps. The disassembled coil is

easy to transport and will always be ready for use.

Two adjustable carrying straps are supplied with

this frame coil.

UNIVERSAL CABLE COIL 4 M PERIMETER

This search coil is identical with the 1 m x 1 m frame

coil described before, but it is supplied without a

frame. Therefore a self made metal free frame has

to be built rst, before mounting the same cable

on it. This coil should only be laid out with a single

winding.
