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 searchcoil 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 searchcoil 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. 9-12).

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

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.

QUICK-START DEMONSTRATION

BASIC OPERATION

POWERING UP

Press the POWER

touch pad.

• The detector will

beep 4 times

• All display

segments will

illuminate

momentarily

• The SENSITIVITY

(left) and BATTERY

(right) indicators will

stay illuminated

MOTION and NO-MOTION MODES

Depending on the operation mode selected, the Discovery 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

SENSITIVITY ▲or ▼keys. The 6-segment scale at the left of the

display, above “coin depth”, indicates the sensitivity level when these

touch pads are depressed.

CAUTION:

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.

Reduce sensitivity if detector emits false signals

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 searchcoil, 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, be

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 DISCRIMINATION ▼

touch pad. Each time the ▼pad is depressed, an illuminated "R" will
