Glossary of Terms
Alloy A substance which is composed
of two or more metals (an alloy may also
include non-metals).
Camlock Lever which releases or locks
detector's assembly components. The
Explorer SE's upper and lower shafts are
held together by the shaft camlock. This
shaft assembly is fixed to the control
box by the control box camlock.
Coil The coil is the circular plate swept
across the ground surface during
detecting. It transmits electromagnetic
signals into the ground and receives the
response.
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 transmitted from the
search coil and provide user access to
functions via the control panel.
Control Panel This panel, which is
the front of the control box, houses
the display screen and provides press-
button access to all of the detector's
operating functions.
Digital One of Explorer SE's displays.
Digital rates an object's conductivity
and ferrous content as a figure between
0 and 31.
Discrimination The ability of a metal
detector to identify the user's desired
target and eliminate signals from
undesirable objects. The Explorer SE can
be programmed to discriminate against
unwanted targets in either Iron Mask or
Discrim.
Discrimination Pattern A two-
dimensional pattern made up of shaded
and clear regions of the Smartfind
screen. Characteristics of a target are
used to determine its position on a two-
dimensional display. A Discrimination
Pattern can be modified by the user to
accept or reject certain targets.
Edit allows the user to customize an
existing Discrimination Pattern to match
preferred target characteristics.
Ferrous Composed of or containing
iron. A ferrous object is one that is
predominantly or completely iron.
Ferrous objects (e.g. nails) are usually
not desired by the detectorist.
Ferrous Content While metals are
commonly divided between ferrous and
non-ferrous metals, this usually refers to
them being magnetic or non-magnetic.
However most metals do have some
ferrous content, even when classed as
'non-ferrous'.
Except for the very purest of metals, the
Explorer SE is able to test the ferrous
content of a metal target and use this in
it's target identification.
Full Band Spectrum (FBS)
Simultaneous frequency transmission
ranging from 1.5 kHz to 100 kHz. This
range in frequencies means that the
signals received from the detector
coil are analyzed from a wide range of
responses.
Full Screen Target details shown on the
full screen with display border and the
other screen elements removed. An icon
at the center right of screen switches to
full screen display.
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.

Iron Mask The Iron Mask function
rejects objects with ferrous properties.
This level of ferrous rejection is
represented with a dark 'curtain' which
moves across the horizontal dimension
of the Smartfind screen as the Iron Mask
is adjusted.
Learn allows the user to accept or reject
certain targets to create a personalized
Discrimination Pattern.
Low-ferrous containing little iron. Low-
ferrous objects or non-magnetic metals
(such as silver or copper coins, gold
jewelry, etc).
Mineralized Ground
Containing certain minerals which
can cause false signals to be given.
Mineralized ground is handled
automatically by the Explorer SE's
ground compensation.
Nickel Metal Hydride (NiMH) Nickel
Metal Hydride batteries are the modern
equivalent of older NiCad (Nickel
Cadmium) batteries. NiMH batteries
have a longer life-span and are not
affected by memory to the same
degree.
