TERMINOLOGY
The following terms are used throughout the manual, and are standard
terminology among detectorists.
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 coil’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 important feature of professional metal
detectors. Discrimination allows the user to ignore trash and
otherwise undesirable objects.
NOTCH - Notching is the elimination of an item, or range of items, within
the metallic spectrum. We “notch-out” an object, or objects,
selectively. Objects to the left and right on the metallic spectrum
can be retained using the notch technique.
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 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 the most
bothersome trash items 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
Discovery 3300 incorporates proprietary Super
-Scan™ circuitry to
eliminate false signals from severe ground conditions
