T
he Teknetics T
2
is a new high-performance multi-purpose professional
grade metal detector. It utilizes the latest advances in electronic technology,
and its functional design represents the leading edge of the metal detector
engineering art. The T
2
is easier to learn to use properly than other
comparable metal detectors. Its combination of light weight and balance
provides comfort unmatched by any other detector in its price range. Its
most popular uses include coinshooting, relic hunting, and gold prospecting.
TREASURE HUNTER’S CODE OF ETHICS:
• Always check Federal, State, County and local laws before searching.
• Respect private property and do not enter private property without the owner’s permission.
• Take care to refill all holes and try not to leave any damage.
• Remove and dispose of any and all trash and litter found.
• Appreciate and protect our inheritance of natural resources, wildlife and private property.
• Act as an ambassador for the hobby, use thoughtfulness, consideration and courtesy at all times.
• Never destroy historical or archaeological treasures.
• All treasure hunters may be judged by the example you set; always conduct yourself with
courtesy and consideration of others
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.
