Terminology - Teknetics DigiTek Owner's Manual

TERMINOLOGY

The following terms are used throughout the manual, and are standard
terminology among detectorists.
A relic is an object of interest by reason of its age or its association with
RELIC
the past. Many relics are made of iron, but can also be made of bronze
or precious metals.
Iron is a common, low-grade metal that is an undesirable target in certain
IRON
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.
Metals which are made of, or contain, iron.
FERROUS
Reference to a metal being "eliminated" means that the detector will not
ELIMIN TION
emit a tone, nor display a Target-ID, when a metal object passes through
the searchcoil's detection field.
When the detector emits different tones for different types of metals, and
DISCRIMIN TION
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 is the process of finding the exact location of a buried object.
PINPOINTING
Long-buried metals can appear exactly like the surrounding soil, and can
therefore be very hard to isolate from the soil.
Ground Cancelation is the ability of the detector to ignore, or "see through,"
GROUND C NCEL TION
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.
