TERMINOLOGY

HEADPHONE JACK

The following terms are used throughout the manual, and are standard
terminology among detectorists.

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 coil’s detection field.

DISCRIMINATION

When the detector emits different tones for different types of metals, and
when the detector "eliminates" certain metals, we refer to this as the
detector "discriminating" among different types of metals.
Discrimination is an important feature of professional metal detectors.
Discrimination allows the user to ignore trash and otherwise undesirable
objects.

RELIC

A relic is an object of interest by reason of its age or its association with
the past.  Many relics are made of iron, but can also be made of bronze
or precious metals.

IRON

Iron is a common, low-grade metal that is an undesirable target in certain
metal detecting applications.  Examples of undesirable iron objects are
old cans, pipes, bolts, and nails.
Sometimes, the desired target is made of iron.  Property markers, for
instance, contain iron.  Valuable relics can also be composed of iron;
cannon balls, old armaments, and parts of old structures and vehicles
can also be composed of iron.

FERROUS

Metals which are made of, or contain, iron.

PINPOINTING

Pinpointing is the process of finding the exact location of a buried object.
Long-buried metals can appear exactly like the surrounding soil, and can
therefore be very hard to isolate from the soil.

PULL-TABS

Discarded pull-tabs from beverage containers are the most
bothersome trash items for treasure hunters.  They come in many
different shapes and sizes.  Pull-tabs can be eliminated from
detection, but some other valuable objects can have a magnetic
signature similar to pull-tabs, and will also be eliminated when
discriminating out pull-tabs.

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. This Detector incorporates proprietary circuitry
to eliminate false signals from severe ground conditions

The detector has a 1/8” & 1/4” headphone jack on the left side of the
housing.

Optional Headphones come standard with a 1/8” stereo plug (the 1/4”
adapter is not required).

When the headphone jack is connected, speaker audio is disabled. Using
a detector with headphones facilitates detection of the weakest signals
and also extends the battery life.
