Camlock Lever that releases or locks detector’s assembly components.
Conductivity A measure of the ability of a target to allow eddy currents induced
by the transmitter.
Control box Encloses the electronic components necessary to generate and interpret
signals and provide user access to functions via the control panel.
Control buttons Buttons on the control panel that offer quick access to the functions
and settings most likely to be used during detector operation
e.g. PINPOINT and ACCEPT/REJECT.
Control panel Houses the display screen and provides press-button access to all of
the detector’s operating functions.
Discrimination The ability of a metal detector to identify the user’s desired target and
eliminate signals from undesirable material.
Ferrous Composed of or containing iron. Ferrous objects (e.g. nails) are usually
not desired by the detectorist.
Full Band Spectrum Simultaneous transmission ranging from 1.5kHz to 100 kHz.
(FBS)
This range in frequencies means that the signal received from the detector
coil is analyzed from a wide range of responses.
Ground compensation
The ability of the detector to compensate for the effects of
ground mineralization.
Handle assembly Part of the detector made up of the control box, handle and armrest.
Mineralized ground Ground containing certain minerals, which can cause false signals
to be given.
Nickel Metal Hydride NiMH batteries have a longer life span and are not affected by
(NiMH) memory to the same degree as some other rechargeable batteries.
Non-ferrous Not containing iron. Non-ferrous objects or non-magnetic metals
(such as silver or copper coins, gold jewelry, etc).
Pinpoint Function allowing an object to be precisely located. PINPOINT
overrides the automatic motion detection and discrimination
settings of the Quattro MP.
Response The signal or audible indication of a target.
Search coil The search coil is the circular plate swept across the ground surface
during detecting. It transmits signals into the ground and receives
the response.
Sensitivity The detector’s level of response to a target in the presence of ground
noise and/or electromagnetic disturbance.
Shaft assembly An adjustable assembly made up of the upper and lower shaft
connected by camlocks. The shaft assembly connects the search
coil to the handle assembly.
Threshold (hum) The audible level of sound emitted when no target is detected
is the THRESHOLD. This threshold hum is the background sound made as
the Quattro MP operates. THRESHOLD can be set anywhere between
no sound (silent) and loud.
