OWNER’S MANUAL
The
Legacy 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)

TERMINOLOGY
The following terms are used throughout the manual, and are standard
terminology among detectorists.
ELIMINATION
detector will not emit a tone, nor light up an indicator, when a
specified object passes through the coil’s detection field.
-
Reference to a metal being "eliminated" means that the
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 -
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.
Discarded pull-tabs from beverage containers are the most
GROUND BALANCE - Ground Balancing is the ability of the detector to
ignore, or "see through," the earth’
and only sound a tone when a metal object is detected. The

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

MOTION and NO-MOTION MODES
Depending on the operation mode selected, the Legacy 3300 detects
metal both with the coil in motion, or with the coil motionless. In the
PINPOINT mode of operation, metal is detected with the coil
motionless over the ground. This no-motion operation helps to locate
the exact location of buried objects, and is very useful in
understanding the size and shape of buried metal objects. The
PINPOINT mode offers deeper ground penetration, but cannot
classify targets, nor indicate their depth.
The other operating modes require the coil to be in motion to detect
a target. When in the DISCRIMINATION, ALL-METAL or NOTCH
modes, the coil must be in continuous motion. It is often useful to
search for targets in a motion mode, and when identified, pinpoint
their location with the PINPOINT control.
SENSITIVITY
At its default sensitivity setting, the detector will detect a coin-sized
object, such as a quarter, buried approximately seven inches deep.
To change the sensitivity level, and thus the detection depth, press the

At higher sensitivity levels, the detector is susceptible to electromagnetic
interference from electronic devices. Reduce sensitivity if demonstrating
indoors or if using near power lines or electrical equipment.

BASIC OPERATION
continued
ALL METAL MODE (Default Operation)
The detector defaults to ALL METAL mode after powering on. In this
mode, all types of metals will be detected. An object’s PROBABLE
identification is indicated by the arrows at the top of the display. In
addition, the PROBABLE depth of coin-sized objects is indicated by
the rectangular segment indicators on the left side of the display. All
detected objects will cause the depth indicator to illuminate. The
depth indication is not accurate for larger objects; however, it will
provide accurate relative depth indications. The greater the distance
an object is from the search coil, the greater its depth value.
DISC/ A-M Touch Pad
Pressing this touch pad will cause the
detector to toggle between two
operating modes, DISCRIMINATION
and ALL-METAL. If the detector is in the
ALL-METAL mode (the default mode),
pressing the touch pad will change the
detector into DISCRIMINATION mode.
If the detector is in the
DISCRIMINATION mode, pressing the
touch pad will change the detector into
ALL-METAL mode.
DISCRIMINATION MODE
Discrimination is used to eliminate unwanted objects from detection.
To enter this mode, from ALL-METAL mode, press the DISC/A-M touch pad.
After pressing DISC/A-M, the detector will:
• Beep twice
• Display 3 "R"s under the left-most segments, Iron 1, 2 & 3
Ferrous objects will not be detected in DISCRIMINATION mode.
Heavily oxidized ferrous objects will sometimes, however
detected, usually with a high tone and an indication to the right
of the target identification scale.
To increase the level of discrimination, press the DISCRIMINATION
touch pad. Each time the ▲ pad is depressed, an additional "R" will
appear, thus eliminating from detection the objects which fall into the
corresponding categories.
To decrease the level of discrimination, press the DISCRIMINA
touch pad. Each time the ▼ pad is depressed, an illuminated "R" will

disappear, thus returning to detection the objects which fall into the
corresponding categories.
Discrimination Mode is a fixed-start-point elimination system. Objects
are cumulatively eliminated as the level of discrimination increases.
NOTCH MODE
To selectively eliminate a category from detection within the metallic spectrum,
use the NOTCH Mode.
Technical Note:
The NOTCH touch pad causes the status of an "R" segment to toggle
between ON and OFF.
To use the NOTCH Mode:
The NOTCH touch pad can be depressed at any time. But for
first-time use, place the detector in DISCRIMINATION mode.
A first demonstration is best accomplished as follows:
1) Turn the power OFF.
2) Turn the power ON.
3) Press DISC/A-M
4) Press NOTCH.
A flashing "R" will appear under the IRON-1 segment.
5) Press the DISCRIMINATION
Notice that the "R" moves upon each press of the
DISCRIMINATION ▲ touch pad.
6) Press NOTCH again.
The flashing "R" will become permanently illuminated.
▲ touch pad several times.
If an object has been “notched-out”, you can return it to detection status.
To “un-notch” a category:
1) Press NOTCH.
2) Move the flashing “R” over the permanently illuminated “R”, using
the DISCRIMINATION ▲ or ▼ touch pads.
3) Press NOTCH again.
After NOTCHING OUT a category the detector returns to the
DISCRIMINATION mode
ZAP
The ZAP control is a convenient way to eliminate a known undesirable
metal object from detection. Zap only works in DISCRIMINA
To demonstrate the ZAP control:
1) Set the detector in DISCRIMINATION Mode
2) Pass the search coil over an undesirable object.
3) Notice the Target Indication
Note: You can only ZAP objects that register under the
seven left-most segments (from Iron to Zinc).

4) Press ZAP. An "R" appears under the segment to be eliminated.
5) Pass the search coil over the same object again.
The undesirable object is eliminated from detection
The ZAP control is easy to use in the field. As you are detecting, and
encounter an object which you wish to eliminate from detection, simply
press the ZAP touch pad after detecting the object.
The ZAP control eliminates the most-recently detected object category from
detection. The category eliminated is indicated with an "R".
continued
PIN POINT MODE
Since long-buried objects can appear exactly like the surrounding soil, the
process of finding the exact location of a small object, such as a coin, can be
time-consuming and frustrating. Objects buried many inches deep present
an especially daunting challenge. In addition, during the unearthing process,
care must be taken not to damage valuable relics. The best solution to these
problems is the no-motion PINPOINT mode.
At any time during operation, press the PINPOINT touch pad, and the
detector enters the no-motion mode. In the PINPOINT mode, any object in
the coil’s detection field will induce a monotone hum. Pass the coil slowly
over and around the target zone. The target is where the sound is loudest.
See “In the field techniques” for more information on pinpointing techniques.
Be sure that the detector is properly GROUND BALANCED before using the
PINPOINT MODE. See page 20 for manual ground balancing instructions.
The Target Identification and Target Depth indicators are disabled in this
mode. To discern the identification and depth of an object, you must use one
of the motion modes of operation.
HEADPHONE JACK
Using headphones (not supplied) with
your metal detector makes it easier to
identify subtle changes in the
threshold levels for better detection
results, and also reduces drain on the
batteries. The Legacy 3300 Metal
Detector has a stereo headphone jack
located at the rear of the case.
This device is to be used with
interconnecting cables/headphone
cables shorter than three meters.
12
AUDIO TARGET IDENTIFICATION
(motion modes only)
While the LCD (Liquid Crystal Display) is very accurate in identifying buried
objects, the user in the field does not always maintain the display screen in
his field of vision. Therefore, we have incorporated an audio feedback
mechanism to alert the user to the nature of buried objects. This audio
feedback system first alerts the user to the presence and classification of
objects, whose nature and location can be confirmed using the LCD display.
The 4-tone audio target identification system functions only in the motion
modes of operation. The detector must be in the DISCRIMINATION,
NOTCH or ALL-METAL modes, as indicated on the display. In PINPOINT
mode, the detector will emit only a monotone sound.
The detector can sound four different tones, depending on the object detected.
BASS TONE
Ferrous objects, such as iron and steel, will induce a bass tone.
The smallest gold objects can also induce a bass tone.
Most Steel bottle caps.
LOW TONE
Pull-Tabs, nickels & smaller gold
MEDIUM TONE
Newer pennies (post-1982), larger gold objects, zinc, small brass
objects, and most bottle screw caps will induce medium tones.
Many recent vintage foreign currencies will induce medium tones.
HIGH TONE
Silver and copper coins, larger brass objects, older pennies (pre-
1982), and highly oxidized metals will induce high tones. Quarters,
dimes and other precious coins fall into this category.

DEPTH AND TARGET DISPLAY
(motion modes only)
READING THE DISPLAY
The Liquid Crystal Display (LCD) shows
the PROBABLE identification of the
targeted metal, as well as the PROBABLE
depth of the target, in inches.
The detector will register a repeating,
unchanging target identification 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, or oxidized metal. With
practice, you will learn to unearth only the
repeatable signals.
The segment identifications are highly
accurate, when detecting the objects
described on the label. However, if you
register in a given category for an unknown
buried object, you could be detecting a
metallic object other than the object
described on the label, but with the same
metallic signature. Also, the greater the
distance between the target and the coil,
the less accurate the target identification.
GOLD TARGETS Gold objects will
register on the left side of the LCD scale.
Gold will register depending upon its
size. The smaller the gold object, the
further to the left it will register.
Gold flakes will register under Iron-1
Small gold items will register under Iron
or 5¢/PT.
Medium-sized gold items will register
under PT or S-cap.
Large gold items will register under Scap or Zinc.
SILVER TARGETS: Silver objects will
register to the right of the scale, under
25¢, 50¢, or $1, depending on the size
of the object. The larger the object, the
farther to the right it will register.
IRON: Ferrous objects will register on
the far-left side of the target
identification scale. 1, 2, or 3 indicates
the relative size of iron objects. Small
nails, for instance, will usually
illuminate the Iron-1 arrow whereas
large structural ferrous objects will
usually illuminate the Iron-3 arrow.
14
Objects in this category could be worthless
scrap, or a more valuable iron relic.
5c/PT: Nickels and most newer pulltabs(those that stay attached to the
can) will 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: Newer pennies (post-1982) will
register here. Many non-U.S. coins of
recent vintage will also register here.
Cu10¢: Dimes and pre-1982 pennies will
register here. Older, pre-1982, pennies
are composed of copper, which has a
metallic signature similar to a dime. Most
copper coins will register here.
Caution: The target indications are visual
references. Many other types of metal
can fall under any one of these
categories. While the Legacy 3300 will
eliminate or indicate the presence of most
common trash items, it is impossible to
accurately classify ALL buried objects.
DEPTH INDICATOR:
The Depth Indicator is accurate for
coin-sized objects. It indicates the
depth of the target, in inches. Large
and irregularly-shaped objects will
yield less reliable depth readings
When passing over an object, the
depth indicator will light up and stay
illuminated until another object is
scanned. Repeated indication at the
same depth level indicates an accurate
target detector. If the depth indication
varies with each sweep, try sweeping
at different angles; there may be more
than one target present. With practice,
you will learn the difference between
accurate readings, multiple targets, and
highly erratic readings which evidence
trash or irregularly shaped objects.
DEPTH AND TARGET DISPLAY
(motion modes only)
THREE DIGIT TARGET INDICATOR
The three digit target indicator, in the
middle of the LCD display, provides a
specific target value to help identify buried
targets more accurately. With practice in
the field, you will learn to associate target
values with the probable identification of
buried objects. The target value can vary
each time the coil passes over the target,
depending upon the angle of the object
and the distance from the coil. As a
starting point, refer to the table below.

equivalents. With experience in the filed, you will recognize
many types of metals by their numeric value.

SENSITIVITY ADJUSTMENT
(motion modes only)
ELECTROMAGNETIC
INTERFERENCE
The principle use for the
Sensitivity Control is to
eliminate Electromagnetic
Interference (EMI).
A hobby metal detector is an
extremely sensitive device;
the search coil creates its
own magnetic field and acts
like an antenna. If your
detector beeps erratically
when the search coil is
motionless, the unit is probably detecting another electromagnetic field.
Common sources of EMI are electric power lines, both suspended and
buried, motors, and household appliances like computers and
microwave ovens. Some indoor electronic devices, such as dimmer
switches used on household lighting, produce severe EMI and can cause
the detector to beep erratically. Other metal detectors also produce their
own electromagnetic fields; so if detecting with a friend, keep two metal
detectors at least 20 feet apart.
If the detector beeps erratically,
pressing the Sensitivity ▼ Pad on the left of the control panel.
REDUCE THE SENSITIVITY by
SEVERE GROUND CONDITIONS
A secondary use for the Sensitivity Control is to reduce false detection
signals caused by severe ground conditions. While your Legacy 3300
contains circuitry to eliminate the signals caused by most naturally
occurring ground minerals, 100% of all ground conditions cannot be
anticipated. Highly magnetic soils found in mountainous and goldprospecting locations can cause the detector to emit tones when metal
objects are not present. High saline content soils and sands can
sometimes cause the detector to false.
If the detector emits false, non-repeatable, signals, REDUCE THE
SENSITIVITY.
MULTIPLE TARGETS
If you suspect the presence of deeper targets beneath a shallower target,
reduce the sensitivity to eliminate the detection of the deeper targets, in
order to properly locate and identify the shallower target.
16
IN THE FIELD TECHNIQUES
(motion modes only)
PINPOINTING IN MOTION MODES
Accurate pinpointing takes practice
and is best accomplished by
“X-ing” the target area.
1. Once a buried target is indicated
by a good tone response,
continue sweeping the coil over
the target in a narrowing
side-to-side pattern.
2. Take visual note of the place on
the ground where the “beep”
sounds.
3. Stop the coil directly over this
spot on the ground.
4. Now move the coil straight
forward and straight back
towards you a couple of times.
5. Again make visual note of the
spot on the ground at which
the “beep” sounds.
6. If needed, “X” the target at
different angles to “zero in” on
the exact spot on the ground at
which the “beep” sounds.
COIL MOVEMENT
When swinging the coil, be
careful to keep it level with the
ground about 1/2 inch from the
surface. Never swing the coil like
a pendulum.
WRONG
CORRECT
When pinpointing a target, try drawing an “X”,
as illustrated, over where the tone is induced.
17
IN THE FIELD TECHNIQUES
(motion modes only)
Swing the search coil slowly,
overlapping each sweep as you
move forward. It is important
to sweep the coil at a consistent
speed over the ground as you
search. After identifying a
target, your sweep technique
can help in identifying both the
location and the nature of the
target. If you encounter a weak
signal, try moving the coil in
short, rapid sweeps
over the target zone;
such a short rapid
sweep may provide
a more consistent
target
identification.
Most
worthwhile
objects
will
respond with a repeatable tone.
If the signal does not repeat
after sweeping the coil directly
over the suspected target a few
times, it is more than likely
trash metal.
Crossing the target zone with
multiple intersecting sweeps at
multiple angles is another way
to verify the repeatability of the
signal, and the potential of the
buried target. To use this
method, walk around the target
area in a circle, sweeping the
coil across the target
repeatedly, every 30 to 40
degrees of the circle, about ten
different angles as you walk
completely around the target.
If a high-tone target completely
disappears from detection at a
given angle, chances are that
you are detecting oxidized
ferrous metals, rather than a
silver or copper object. If the
tone changes at different

angles, you may have
encountered multiple objects.
If you are new to the hobby,
you may want to dig all targets
at first. With practice in the
field, you will learn to better
discern the nature of buried
objects by the nature of the
detector’s response.
You may encounter some false
signals as you proceed. False
signals occur when the detector
beeps, but no metal target is
present. False signals can be
induced by electromagnetic
interference, oxidation, or
highly mineralized ground
soils. If the detector beeps
once, but does not repeat the
signal with several additional
sweeps over the same spot,
there is probably no target
present.
When searching very trashing
ground, it is best to scan small
areas with slow, short sweeps.
You will be surprised just how
much trash metal and foil you
will find in some areas. The
trashiest areas have been
frequented by the most people,
and frequently hold the most
promise for finding the most
lost valuables. To make
searching easier in very trashy
areas, consider purchasing a 4inch Search Coil. The 4-inch
coil’s narrower detection field
can better distinguish between
two objects in close proximity.
Also maintain the search coil
positioned just above the
surface of the ground, without
making contact with the
ground. Making contact with
the ground can cause false
signals.
False High Tones:
If detector emits false high
tones in DISCRIMINATION
mode, rotate the GROUND
BALANCE knob slightly
counter clock wise.

GROUND BALANCING
Before using the PINPOINT mode, it is necessary to ‘Ground Balance”
your detector, this ground balancing adjustment offsets the effects of
minerals and slats in he ground.
To GROUND BALANCE your detector:
1. Using the ALL-METAL mode, find a patch of ground which is free of metal
objects. You will use this section of ground to test the detector. The presence of any metal objects in this area will interfere with this procedure.
2. Begin with the ground balance KNOB
in the PRESET position.
3. Lift the search coil waist high in the air.
4. Press the PINPOINT touch pad.

5. Lower the search soil to the ground, maintaining
it elevated about 1/2 inch above the surface (be
sure that this ground does not contain metal).
• If the detector emits sound with the search
coils 1/2 inch over the ground, further
MENT IS NECESSARY.
• If the detector remains silent with the
searchcoil 1/2 inch over the ground,
no further adjustment is
necessary; the detector
is

6. If the detector emits sound with the coil over the ground in STEP 56,
further adjustment of the ground balance KNOB is required as follows:
• Lift the search coil waist high
• Rotate the ground balance KNOB clockwise 1/16 of a turn
• Press PINPOINT
• Lower the search coil to the ground again
If the detector still emits a tone, repeat the procedure. You are searching
for the ground balance knob positiion where the detector is
It is important to move the knob in small increments in order to find
the first setting (moving clockwise) at which the detector remains
silent. To insure yourself of the optimal adjustment, move the KNOB
slightly counterclockwise from a silent-adjusted position to check for
the
most counterclockwise silent position possible.
If the KNOB is over-adjusted in the clockwise direction, the detector
can lose sensitivity. An over-adjusted condition can also cause the
detector to sound off when the coil is lifted away from the ground.
As your search takes you to different areas, verify the ground balance setting periodically using the above procedure. Within a geographical area,
ground conditions can change. Varying elevation, proximity to water, and
concentration of rock, sand or clay can all affect ground condition and
sometimes require recalibrating with the ground balance knob.

IN THE FIELD TECHNIQUES
In the PINPOINT Mode, coil sweep technique is not important. Rather,
user retuning is critical.
The detector does not automatically adjust to changing ground and
environmental conditions; the operator is required to make the
adjustment. If the detector sounds a constant tone over all areas of the
ground, retune the detector by pressing the PINPOINT button.
Pinpoint is used to find the exact location of a target which was previously
located and identified using the discrimination mode. As this mode does
not require motion over the target, the user can move the coil more slowly
and then narrow the detection field when near the target.
How to Pinpoint
Position the searchcoil an inch or two above the ground, and to the side of
the target. Then press PINPOINT. Now move the searchcoil slowly across
the target, and the sound will communicate the target’s location. As you
sweep from side to side, and hear no sound at the ends of the sweep, the
target is located in the middle of that zone, where the sound is loudest. If the
sound is loud over a wide area, the buried object is large. Use Pinpoint to
trace an outline of such large objects.
Narrow It Down
To further narrow the field of detection, position the searchcoil near the
center of the response pattern (but not at the exact center), and press
PINPOINT again. Now you will only hear a response when the searchcoil
is right over the top of the target. Repeat this procedure to narrow the
zone even further. Each time you repeat the procedure, the field of
detection will narrow further.
- No-motion Pinpoint
Consider Purchasing a Pinpointer
When you kneel down to unearth an object, you may find it frustrating as
the object can appear exactly like the surrounding soil. You may hold the
object in your hand, and find it necessary to pass a handful of dirt over the
searchcoil to see if it contains metal. An easier way is to use a handheld
pinpointer. It is a probe-like device which is poked into the ground, making
close up pinpointing a snap, reducing digging time, and minimizing the size
of the holes you will dig. Bounty Hunter offers a robust and inexpensive
pinpointer designed for this purpose.
