Elimination - Reference to a metal being "eliminated" means that the
detector will not emit a tone,
nor light up an indicator, when a
specified object passes through the search coil's detection field.
Discrimination - When the detector emits different tones for
different types of metals, and when the detector
metals, we refer to this as the detector "Discriminating" among
different types of metals.
Pinpointing - Pinpointing is the process of finding the exact
location of a buried object. Long-buried metals
can appear to the eye
exactly like the surrounding soil, and can therefore be very hard to
isolate from the soil.
Ground Balance - Ground balancing is the ability of the detector
to ignore, or "see through"
the earth's naturally occurring minerals,
and only sound a tone when a metal object is detected.
11.5*15" Big Coil - Longer detecting distance and deeper searching range.
