5. Glossary
Following terms used throughout the manual are standard terminology among detectorists.

Elimination
Reference to a metal being "eliminated" means that the detector will not emit a tone, not light up an
indicator when a specified object passes through the coil's detection field.

DISC - Discrimination
When the detector emits different tones for different types of metal, 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 for professional detectorists. Discrimination allows the
user to ignore trash and otherwise undesirable objects.

Notch
Notching is the elimination of an item or range of items within the metallic spectrum. We "notch out"
an object or objects selectively.

Auto-notch
It eliminates trash metals automatically and keep the detection for most coins. The auto-notch range
is preset and not adjustable.

Relic
A relic is an object of interest because of its age or its association with the past. Many relics are
made of iron, but can also be made of bronze or other precious metals.

Iron
Iron is a common, low-grade metal that is an undesirable target in certain metal detecting
applications. Examples of such 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 such as cannon balls, old armaments, and parts of old structures
and vehicles.

Ferrous
Adjective for an object made of or containing iron.

GND TRAC - Ground tracking
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-tab from beverage cans are the most bothersome trash items for the treasure hunter.
They come in many different shapes and sizes, and can be eliminated from detection. However, some
other valuable objects have a magnetic signature similar to pull-tabs and will also be eliminated
when discriminating out pull-tabs.

GND BAL - Ground balance
The ability of a metal detector to cancel or ignore ground mineralization, eliminating false signals
from severe ground conditions and only emitting a tone when a metal object is detected.

SURF ELIM - Surface elimination
A detector's ability to ignore all targets on or near the ground's surface, which is useful in heavy
trash areas.
