HOW METAL DETECTORS WORK
Most hobby metal detectors use VLF Induction Balance technology. Here’s how they work.
The searchcoil (also called search head or loop) contains two electrical induction coils which
are like antennas. One coil transmits a rapidly alternating magnetic field, illuminating the
region surrounding the searchcoil. If metal is present, its electrical conductivity distorts the
magnetic field. If iron metal is present, its magnetism also distorts the magnetic field, but in a
different way, allowing the metal detector to distinguish between ferrous and nonferrous
metals.
The other coil is a receiving antenna which detects changes in the magnetic field caused by
the presence of metal. Electronic circuits amplify this weak signal, analyze it to determine the
changes which occur as the searchcoil sweeps over the target, and then convey the
information to the user in the form of a visual display or audio tones. Most modern metal
detectors perform many of these tasks in software running on an internal microcomputer.
The iron minerals which are present in most soils also distort the magnetic field, obscuring the
weak signals of small or deep objects. This can cause the object to go undetected, or to be
misidentified when it is detected. Much of the technology that goes into modern metal
detectors is devoted to the task of eliminating the unwanted signals from iron minerals in the
soil, while not losing the signals from metal objects.

Detecting Activities (continued)
Shallow Water Hunting
(continued)
Salt water is highly conductive, and produces a strong signal which is like that of metal.
Therefore the T
2
is not suitable for use in or over salt water. In order to use the T
2
over wet
sand, or salt water beaches, do the following:
1. Set the sensitivity in both modes to 30 or less.
2. Ground cancel the machine manually in All Metal mode.
3. Search in the Discrimination mode with a discrimination setting higher than 45, using
the 1+ # OF TONES method.
