The Basics Of Metal Detecting - Bounty Hunter Lone star Pro Owner's Manual

THE BASICS OF METAL DETECTING

This metal detector is intended for locating buried metal objects. When
searching for metals, underground or on the surface, you have the following
challenges and objectives:
1. Ignoring signals caused by ground minerals.
2. Ignoring signals caused by metal objects that you do not want
to find, like nails.
3. Identifying a buried metal object before you dig it up.
4. Estimating the size and depth of objects, to facilitate digging them up.
5. Eliminating the effects of electromagnetic interference from other
electronic devices.
Your metal detector is designed with these things in mind.
1. Ground Minerals
All soils contain minerals. Signals from ground minerals can interfere with
the signals from metal objects you want to find. All soils differ, and can differ
greatly, in the type and amount of ground minerals present. This detector
has proprietary circuitry to automatically eliminate interfering signals from
minerals that occur naturally in the ground.
NOTE: This detector will not completely eliminate interference from all types
of minerals. For example, the detector IS NOT designed for use on wet
sand saltwater beaches. Another example of soil this detector will not
eliminate is any soil containing large concentrations of iron oxides, which are
usually red in color.
2. Trash
If searching for coins, you want to ignore items like aluminum foil and nails.
You can see the Target-ID of the buried objects, listen to the sounds and
then decide what you want to dig up. Or you can eliminate unwanted metals
from detection by using the DISCRIMINATION feature.
3. Identifying Buried Objects
Metal objects are identified along the 9-segment Conductivity Arc. This scale is an
indicator of the relative electrical conductivity of different objects. Segments to the
right indicate more conductive targets. Iron objects, which are usually of lesser
value, illuminate on the left-most segments. Silver objects illuminate on the right-
most segments.
4. Size and Depth of Buried Objects
The 3-segment graphic indicates the relative depth of a buried metal object.
This graphic can indicate the relative size of different objects or their distance from
the searchcoil. For a given object, the more distance between it and the searchcoil,
the more arrows illuminated.

DEPTH AND TARGET DISPLAY
Please refer to the display on your
detector and reference the TARGET-ID
categories below applicable to your
model (not all detectors include all of
these categories).
READING THE DISPLAY
The display shows the PROBABLE
identification of the metal detected, as well
its PROBABLE depth.
The detector will register a target
identification, upon each sweep of the
searchcoil, when a buried target has been
located and identified. If, upon repeated
passes over the same spot, the target
identification reads inconsistently, the
target is probably a trash item. With
practice, you will learn to unearth only the
repeatable signals.
The segment identifications are highly
accurate, when detecting the objects
described on the faceplate. However, if an
object registers in a given category for an
unknown buried object, you could be
detecting a metallic object other than the
object described on the faceplate, but with
the same metallic signature. Also, the
greater the distance between the target
and the searchcoil, the less accurate the
target identification.
GOLD TARGETS Gold objects will
generally register toward the middle or
left-of-center on the scale.
Gold flakes will register under iron.
Small gold items will register under foil
or 5¢.
Large gold items will register toward the
center of the scale.
SILVER TARGETS: Silver objects will
register to the right of the scale, under
dime or higher.
IRON: All sizes of iron objects will register
on the far-left side of the scale. This could
indicate a worthless item such as a nail, or
a more valuable historic iron relic.
FOIL: Aluminum foil, such as a gum
wrapper, will register as foil. A small
broken piece of pull tab may also register
here.
5¢: Most newer pull-tabs from beverage
cans, the type intended to stay attached
to the can, will register here. Many gold
rings will also register here.
ALUM: Older pull-tabs, which always
detached completely from the can, register
here. Many medium-sized gold rings also
register here.
PT (pull-tabs): Pull-tabs from older
beverage cans will register here. Few
newer pull-tabs will also register here.
Many gold rings will also register here.
S-CAP: Older screw caps from glass
bottles will register here. Large gold rings,
like a class ring, could also register here.
Some non-U.S. coins of recent vintage
will also register here.
Zinc: Medium conductivity objects and
many non-U.S. coins of recent vintage are
classified here.
The Target Identification Categories to the
right of the display, such as 10¢, DIME,
25¢, Quarter, 50¢ and $1 accurately
identify these U.S. coins. When used in
areas outside the U.S., these categories
identify coins or metal objects of high
relative conductivity (such as silver coins
or relics), or large objects made of any
type of metal.
Caution: The target indications are
visual references. Many other types of
metal can fall under any one of these
categories. While the detector will
eliminate or indicate the presence of most
common trash items, it is impossible to
accurately classify ALL buried objects.
