TERMINOLOGY
The following terms are used throughout the manual, and are standard
terminology among treasure hunters.
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 searchcoil’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 essential feature of professional metal detectors.
Discrimination allows the user to ignore trash and other 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 to the eye 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 an especially
bothersome trash item 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. The G2 incorporates proprietary circuitry and
programming to eliminate false signals from severe ground conditions.
Gold Nugget Hunting
with the Optional 5” DD Searchcoil
With the purchase of the 5” searchcoil, you can bring more precision to your
search for the smallest gold pieces.
The standard 11” DD Teknetics searchcoil is engineered for depth.
If you want to find the smallest pieces that the 11” DD might miss, consider the
5” coil.
Advantages of the 11” DD searchcoil are:
1 Deeper detection
2. Broader sweep (cover more area in less time)
Disadvantages of the 11” DD searchcoil over the optional 5” searchcoil are:
1. Less separation between adjacent buried targets.
Not as good at extremely trashy sites.
2. Loss of sensitivity to the tiniest gold pieces.
3. Does not fit into tight spaces as well.
Notice:
If you use the 5” searchcoil,
YOU MUST install a single
rubber washer
at the
searchcoil connection point.
