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 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.
V.C.O.
Meaning “voltage controlled oscillator,” the V.C.O. audio method causes
both the audio pitch and the volume to rise as signal strength increases.
V.C.O. improves the user's ability to interpret a target's size and depth.
Very weak signals (for small or very deeply buried objects) have the
faintest volume and the lowest pitch. Larger objects, and those closer to
the searchcoil, will induce a higher volume and higher pitch sound.
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.
