Any mode or control setting
allowing total acceptance of all metal types, iron, aluminum,
brass, lead, copper, silver etc.
ID: Circuitry which produces
different audio tones (pitch) for different target's conductivity.
Sand: One of the most extreme
components of non-conductive, negative ground minerals. Magnetic.
called Magnetite (Fe304) or magnetic iron oxide.
Any intentionally buried
or secreted hoard of valuables.
Salts: One of the major
mineral types which make up the positive ground minerals. Wet
will produce a positive response due to its similar conductivity
The measure of a metal
target's ability to allow eddy currents on its surface.
The greatest measure of
a metal detectors ability to transmit an electromagnetic field
into the ground.
Method of manually or automatically
desensitizing a metal detector so that it may locate the center
Circuitry which ignores
or otherwise indicates, a specific target based on its conductivity/
A loss or increase in threshold
caused by temperature, time, or battery condition.
Currents: Small circulating
currents of electricity.
Descriptive of any iron
or iron bearing material.
The number of complete
alternating current cycles produced by the transmit oscillator
Balance: A state of operation
in which specialized circuitry can ignore the masking effect
ground minerals have over metal
Rock: A rock which contains
a higher concentration of mineralization than the surrounding
Refers to the total volume
(average) of ground penetrated by a metal detector.
Series of listings and
prompts on a visual display designed to aid the operator in
Metallic substances: iron,
foil nickel, aluminum, gold, brass, copper, silver, etc.
An electronic component
that can be programed to perform certain electronic functions.
Ground: Any soil containing
conductive or magnetic components.
A condition of operation
selected by the operator for specific functions.
Mode: Any mode that requires
loop movement to respond to metals.
Not of iron, any metal
that is not iron.
Mode: Any mode of operation
that doesn't require movement of the loop to respond to metal
The length of time between
eddy current generation sustained on a metals surface and the
electromagnetic field effect on the loops receive winding.
Finding the exact center
of a metal target.
An indication of a target
non-acceptance by silence or a broken sound.
The measure or capacity
of a metal detector to perceive changes in conductivity within
An audio or display response
alerting the operator that a target has been detected.
The ability of a metal
detector to maintain smooth predictable performance.
Refers to any object that
causes an audio or display indication.
ID: A feature which creates
a visual indication to aid in identification of a target.
(Very Low Frequency): A
metal detector that operates in the 3-30 kHz frequency range.
