TERMINOLOGY
The following terms are used throughout the manual, and are standard
terminology among detectorists.
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.
ELIMINATION
Reference to a metal being "eliminated" means that the detector will not
emit a tone, nor display a Target-ID, when a metal 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 important feature of professional metal detectors.
Discrimination allows the user to ignore trash and otherwise undesirable
objects.
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.
GROUND CANCELATION
Ground Cancelation 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. This detector incorporates proprietary circuitry to
eliminate false signals from many mineralized soils.
