Bounty Hunter LEGACY 3300 User Manual 2

OWNER’S MANUAL

The
Discovery 3300
is a professional metal
detector. While the most
difficult aspects of metal detecting
have been automated, it is a
sophisticated electronic device which
requires an understanding of some basic
features and metal detecting concepts.

If you do not have prior experience with a
metal detector, we strongly recommend that you:

1) Adjust the Sensitivity to a low setting in the event

of false signals. Always begin use at a reduced

sensitivity level; use at full sensitivity after you have become
familiar with the detector.

2) Do not use indoors. This detector is for outdoor use only. Many
household appliances emit electromagnetic energy, which can
interfere with the detector. If conducting an indoor demonstration,
turn the sensitivity down and keep the search coil away from
appliances such as computers, televisions and microwave ovens.
If your detector beeps erratically, turn off appliances and lights,
especially those with dimmer switches.

Also keep the search coil away from objects containing metal, such
as floors and walls.

3) Read this manual. Most importantly, review the Quick-Start Demo
(p.7-8) and Basic Operation (p. 9-11).

4) Use 9-volt ALKALINE batteries only. Do not use Heavy Duty
Batteries.

TERMINOLOGY

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.

NOTCH - Notching is the elimination of an item, or range of items, within

the metallic spectrum. We “notch-out” an object, or objects,
selectively. Objects to the left and right on the metallic spectrum
can be retained using the notch technique.

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. The
Discovery 3300 incorporates proprietary Super-Scan™ circuitry to
eliminate false signals from severe ground conditions

ASSEMBLY

Assembly is easy and requires no tools.

●

1 Position the lower stem (the straight tube)

with the silver button toward the back.
Using the bolt and knurled knob,
attach the search coil to the
plastic extension protruding
from the lower stem.

●

2 Press the button on

the upper end of
the lower stem,
and slide the lower
stem into the
upper stem.

Adjust the stem to a length
that lets you maintain a
comfortable upright
posture, with your arm
relaxed at your side, and
the search coil parallel to
the ground in front of you.

●

3 Wind the cable securely around the stem.

●

4 Insert the plug into the

matching connector on
the right underside of the
detector body. Be sure
that the key-way and
pins line up correctly.

Caution: Do not force the

plug in. Excess force
will cause damage.

To disconnect the
cable, pull on the
plug.

Do not pull
on the cable.

ASSEMBLY

Adjusting the Arm Rest

Most people will find the standard position
of the arm rest very comfortable. Very large
forearms and short forearms (particularly
children’s arms), can be accommodated
by moving the arm rest forward.

The arm rest is adjustable to three positions.
To adjust, remove the screw from the

underside, then press the silver button
and move the arm rest to one of the
alternate positions. If you cannot fully
depress the button with your finger, use
a narrow object, such as the blunt end
of a ballpoint pen. The arm rest must
be twisted with moderate force to move
it to an alternate position; this
adjustment is usually made infrequently.

If desired for added stability, re-install
the screw. The screw is not re-installed
in the furthest forward position.

If the button becomes disengaged inside
of the tube, remove the plastic cap at the
end of the tube to access the clip inside.
With a pair of needle-nose pliers,
reengage the button. Then replace the
plastic cap.

Use ALKALINE
batteries only.

To install the
batteries:

●

1 Remove the

battery cover by
disengaging the
clip at the back.

●

2 Align the polarity

of the batteries
correctly, with
the positive "+"
toward the coil
plug connection,
as indicated by
the + and –
indicators on the
housing.

●

3 Insert (2) 9-Volt ALKALINE batteries, with the contacts pointed inward,

and press down on the back of the batteries to snap them into place.
Some brands of batteries will require moderate force to clear the

retaining tabs.
If the batteries fit loosely, and you

want to guarantee a very secure
electrical contact, insert a piece of
paper or thin cardboard between the
back of the battery and the
supporting post.

●

4 Replace the battery door.

Most metal detector problems are due to improperly installed batteries,
or the use of non-alkaline or discharged batteries. If the detector does

not turn on, please check the batteries.
If the detector does not turn on, check to see that the batteries fit tightly.

If the batteries are loose, press them forward while pressing the POWER
touch pad. To tighten up a loose battery, wedge a piece of paper or thin
cardboard between the back of the battery and the supporting post, as
illustrated above.
