TERMINOLOGY
The following terms are used throughout the manual, and are standard
terminology among treasure hunters.
ELIMINATION
Reference to a metal being "eliminated" means that the detector will not
emit a tone, nor light up an indicator, when a specified object passes
through the searchcoil’s detection field.
DISCRIMINATION
When the detector emits different tones for different types of metals, and
when the detector "eliminates" certain metals, we refer to this as the
detector "discriminating" among different types of metals.
Discrimination is an essential feature of professional metal detectors.
Discrimination allows the user to ignore trash and other undesirable
objects.
RELIC
A relic is an object of interest by reason of its age or its association with
the past. Many relics are made of iron, but can also be made of bronze
or precious metals.
IRON
Iron is a common, low-grade metal that is an undesirable target in certain
metal detecting applications. Examples of undesirable iron objects are
old cans, pipes, bolts and nails.
Sometimes, the desired target is made of iron. Property markers, for
instance, contain iron. Valuable relics can also be composed of iron;
cannon balls, old armaments, and parts of old structures and vehicles
can also be composed of iron.
FERROUS
Metals which are made of, or contain, iron.
PINPOINTING
Pinpointing is the process of finding the exact location of a buried object.
Long-buried metals can appear to the eye exactly like the surrounding
soil, and can therefore be very hard to isolate from the soil.
PULL-TABS
Discarded pull-tabs from beverage containers are an especially
bothersome trash item for treasure hunters. They come in many
different shapes and sizes. Pull-tabs can be eliminated from
detection, but some other valuable objects can have a magnetic
signature similar to pull-tabs, and will also be eliminated when
discriminating out pull-tabs.
GROUND BALANCE
Ground Balancing is the ability of the detector to ignore, or "see through"
the earth’s naturally occurring minerals, and only sound a tone when a
metal object is detected. The Gold Bug incorporates proprietary circuitry
and programming to eliminate false signals from severe ground conditions.
TARGET PINPOINTING
After you have identified a target using Discrimination mode,
press-and-hold the PINPOINT button to identify the target’s exact
location. This technique can yield more information about the target’s
shape and size and also find its exact location to facilitate extraction.
Pinpoint as follows:
1.
Position the searchcoil just barely off the ground, and to the side of
the target.
2. Now move the searchcoil slowly across the target; you can locate
it by the sound. The target is located directly under where the
sound is loudest.
Narrow It Down:
1.
To narrow the response further, position the center of the searchcoil
near the center of the response pattern, but not directly over the
center.
2. Release the PINPOINT button.
3. Press-and-hold PINPOINT button again.
4. Repeat this narrowing procedure to narrow the field of detection
further.
Note: Depth indication is less accurate
after narrowing.
SEARCHCOIL DRIFT
If you plan to use the PINPOINT mode for
continuous searching, realize that drift will
occur
over
time,
causing
the detector
to gain or lose
sensitivity. Periodic
retuning of the detector
is required to minimize
drift; release and press
PINPOINT again to retune.
