GLOSSARY OF TERMS
Air Test - A sensitivity test performed by
outwardly moving various sized metal
samples under the metal detector searchcoil to measure the distance limit of detection. This test is not always an accurate
indicator of ground depth penetration capability. (See Bench Test)
Alkaline - A class of battery characterized
by the ability to sustain longer periods
of current drain and greater storage life
when compared to the standard carbonzinc type.
Bench Test - An air test to determine at
what discriminate settings various metal
samples are rejected or accepted. The test
is conducted in a non-metallic area.
Cache - Any intentionally buried or secreted hoard of valuables.
Conductivity - The measure of a metal
target's ability to allow eddy current generation on its surface.
Control Housing - A metal or plastic box
which holds circuit boards, indicators, meter, controls and power supply.
Depth Penetration - The greatest measure of metal detector ability to transmit an
electromagnetic field into the soil matrix
and produce a target signal.
Discrimination - Adjustable circuitry
which ignores or nulls audio responses
from a specific conductivity range allowing positive responses to be heard from
metals higher in conductivity above the
discriminate control setting. Designed
primarily to eliminate audio response from
trash metals.
Double Blip - A signal characteristic common to elongated ferrous targets such as
nails detected in the all-metal non-motion
mode.
Faint Signal - A sound characteristic of
targets that are sometimes deeply buried
or very small in size.
False Signal - An erroneous signal created by automatic retuning overshoot,
ground voids or highly mineralized hot
rocks.
Ferrous - Descriptive of any iron or iron
bearing material.
Metal - Metallic substances; iron, foil,
nickel, aluminum, gold, brass, lead, copper, silver, etc.
Metal Detectorist - A person operating
a metal detector in the field. This name is
preferred by many over Treasure Hunter.
Mineralized Ground - any soil that
contains conductive or non-conductive
components.
Motion Discriminator - A detector type
that requires searchcoil motion to activate
its simultaneous ground balance and discriminate functions.
Non-Ferrous - Not of iron. Metals of the
precious class (i.e. gold, silver, copper,
etc.)
Pinpointing - Finding the exact target
location with respect to a searchcoil's designated center. Accomplished by interpreting the centers of audio response width in
perpendicular direction or scans.
Searchcoil - A circular (can be other
shapes) plastic housing containing single
or multiple transmit and receive windings
in a specific orientation or configuration to
emit and receive signals from ground and
targets. (Also called loop or coil).
Searchcoil Cable - An electrostatically
shielded cable of conductors (wires) which
convey signals to/from the searchcoil or
control housing.
Sensitivity - The measure or capacity of
a metal detector to perceive changes in
conductivity within the detection pattern.
Generally, the more sensitivity a detector
can smoothly provide, the more depth it
will achieve.
Signal - An audio response or visual indication alerting the operator that a target
has been detected.
Slow Motion - A description of searchcoil
speed required to operate the motion discriminate mode.
Sweep - the motion one employs in moving the coil.
