TERMINOLOGY

The following terms are used throughout the manual, and are standard
terminology among treasure hunters.
reference to a metal being "eliminated" means that the detector will not
ELIMIN TION
emit a tone, nor light up an indicator, when a specified 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 essential feature of professional metal detectors.
Discrimination allows the user to ignore trash and other undesirable objects.
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
Pinpointing is the process of finding the exact location of a buried object.
PINPOINTING
Long-buried metals can appear to the eye exactly like the surrounding
soil, and can therefore be very hard to isolate from the soil.
Meaning "voltage controlled oscillator", the v.C.O. audio method causes
V.C.O.
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 Balancing is the ability of the detector to ignore, or "see through" the
GROUND B L NCE
earth's naturally occurring minerals, and only sound a tone when a metal
object is detected. The Gold Bug
