Three Tone Target Identification - Bounty Hunter Land Star Owner's Manual

THREE-TONE
AUDIO TARGET
IDENTIFICATION (ATI)
When the Land Star is in the DISC or
NOTCH modes, its Audio Target Iden-
tification (ATI) system automatically
classifies metal objects into three cat-
egories, to make it easier to identify
the type of target being detected.
The detector sounds three different
tones to distinguish between catego-
ries of detected items: a low tone for
small gold and nickel; a medium tone
for most old and new pull-tabs, some
gold and zinc pennies (dated post
1982); and a high tone for silver,
brass, and copper including pennies
(dated pre 1982).
IRON & STEEL: In the DISC mode,
most iron and steel objects will emit a
low tone. On occasion, if the iron is
highly oxidized, a high tone may be
emitted. For instance, some rusted
bottle caps will emit a high tone and
indicate on the LCD readout in the
SILVER range. In the NOTCH and
AUTO NOTCH modes, iron and steel
objects usually will not be detected,
except for oxidized and rusted items
as described above.
GOLD & NICKEL: All nickels and
small gold items will emit a low tone.
Larger gold items will emit a medium
tone; the LCD will still read under the
gold spectrum. It is recommended
when specifically hunting for gold
items to dig both medium and low
tones.

OLD & NEW PULL-TABS: These will
usually emit a medium tone or no tone
at all if in the NOTCH mode. If a pull-
tab is broken in half, the "Beaver Tail"
part will emit a low tone. There are
also pull-tabs that are bent and folded
or highly oxidized that may emit a low
tone.
COPPER, SILVER & BRASS: These
metals usually will all emit a high tone
in the DISC, NOTCH or AUTO
NOTCH modes.
Note: When operating in the ALL
METAL mode, Three-Tone Audio Tar-
get Identification shuts down and only
one constant medium tone is emitted
when a target is detected.

ATI (Audio Target Identification) falls in
three categories—Some iron and steel
will emit high tones depending on
oxidation (level of rust)—Audio response
is not 100% accurate and should only be
considered a reference on average.
TESTING YOUR DETECTOR
1. While testing the unit for its capa-
bility to pick up coins and other
objects, always test away from other
metals—a good start is outside on
the ground. You cannot test a unit
indoors on the floor, because there
is usually metal in the floor that may
conflict with the detector's signal or
even mask the signal completely.
2. If you're not picking up coins or
metal, even though your coil is close
to the objects to be detected, there
is a chance that you are not maneu-
vering the coil properly. Do not
move the coil too quickly and try not
to sweep the coil less than an inch
away from the object.
3. In the DISC, NOTCH or AUTO
NOTCH modes movement is re-
quired before the unit will recognize
a target. If you're air testing, you
need to point the coil to the ceiling
and make sure there is no metal
near the coil whatsoever (see illus-
tration). The object you're testing
with needs to be swung in a side to
side motion before the detector will
be able to recognize it. In the ALL
METAL mode motion is not required
to detect a target.
4. Not all gold rings will give you a low
tone. Some gold rings fall in the pull-
tab range and may emit a medium
tone similar to the pull-tab. Some
pull-tabs, especially if they are bro-
ken in half, will give you a low tone
similar to most gold rings and nick-
els.

5. Zinc pennies will emit a medium
tone instead of a high tone as do
copper pennies, quarters, and
dimes.
6. Do not swing the coil, or the test
object, too quickly or it may give you
a false signal. When repetitively
passing the coil over the object,
allow a few seconds to pass to give
the detector a chance to recover
from its last reading.
For proper air testing, place detector on
table, rotate coil towards the ceiling as
illustrated above. After properly rotating the
coil, remove any watches and rings from your
hands, and make sure no metal in the table
is in close proximity to the coil. Test the
detector by sweeping a metal object across
the coil. If the object is not ID'ing properly, try
waving the object closer to the coil while
making sure the surface of the object is not
on edge—for instance, a coin's surface is
more accurately detected than its edge.
