THANK YOU FOR CHOOSING

GARRETT METAL DETECTORS!

Congratulations! As the proud owner of the Garrett

Master Hunter CX (Computer Express) Plus you

have joined an international family of treasure hunt-

ers. Men, women and children alike have used their

Garrett detectors to nd coins, relics and gold nug-

gets that are valued in the millions of dollars. So, to

get the most out your CX Plus and treasure hunting

experiences be sure to carefully read through this

owner’s manual!

Your Master Hunter CX Plus, whose microprocessor-

controlled circuitry has been acclaimed and proven

through countless hours of eld use, is a ne detec-

tor for hunting coins or any other metallic objects.

It offers the serious metal detector hobbyist added

depth and completely accurate ground balance and

the precise adjustment available only with micropro-

cessor controls. Computer designed circuitry that

responds to signals from revolutionary PROfor-

mance searchcoils results in greater penetration to

discover and locate treasures of all kinds.

Your Master Hunter CX Plus is engineered with mi-

croprocessor based technology and is backed by

more than 40 years of metal detection research and

development by Garrett’s leading team of engineers.

It is remarkable in its ability to locate coins, jewelry

and other metallic objects at exciting depths. And

with Garrett’s revolutionary Graphic Target Ana-

lyzer™ (GTA) display that offers target acceptance /

rejection, precise discrimination and other key infor-

mation, you can spend more time digging treasure

and less time digging trash!

The CX Plus is pre-programmed at the factory to

adapt itself automatically for optimum performance,

yet to always follow your targeting directions. Sim-

ply press the ON touchpad and begin hunting im-

mediately without interference from ground minerals.

Garrett’s unique LCD display shows the identity of

your target. Electronic pinpointing and coin depth

measuring offer added assistance.

To prospect for precious metals or hunt for deeply

buried caches, switch to the All Metal Mode and Fast

Track™ will precisely ground balance the circuitry

ASSEMBLY

No tools are required to assemble the Master Hunter

CX Plus. Hand tighten all necessary parts.

1. Compress the button end of the spring clip and

insert, button end rst into the lower stem of your

detector so that the buttons pop out of the holes as

they do in the upper stem. These two sets of buttons

will enable you to secure the top stem to the control

housing and to adjust the length of the overall stem

to your height so that you can scan with the detector

comfortably.

2. Attach the lower stem to the searchcoil. Make

certain that two rubber washers are inserted into this

stem before slipping the searchcoil onto it. Place the

threaded bolt through the holes in the connector and

hand tighten the knobs. No tools are needed.

3. Depress buttons in the upper stem and slide into

the control housing until they pop into the holes.

4. Depress the buttons in the lower stem and insert it

into the upper stem. Buttons will pop into the holes

and you can achieve the desired stem length. The

third set of holes from the end is most commonly

used.

5. Wrap the searchcoil cable securely around the

stem and connect to the detector. The rst cable turn

goes over the top of the stem. The cable should be

snug, but still loose so that the angle of the search-

coil can be easily changed, if required. To connect

the cable to the detector, insert the cable connector

and rotate the collar clockwise until secure.

FEATURES

1. LCD - The LCD on the Master Hunter CX Plus

provides extensive visual information for the detec-

tor operator. Battery condition is reported continu-

ously while the detector is turned on and information

is provided on detected targets that will aid in their

recovery.

2. UPPER SCALE - The Upper Scale provides in-

formation about detected targets while the operating

mode and battery condition are displayed below.

www.garrett.com

Master Hunter® CX Plus Owner’s Manual 13

Coin depth reads in inches the depth of coin sized

targets. The detector automatically adjusts to re-

port this information correctly whenever the Pinpoint

touchpad is pushed and released, regardless of

which size searchcoil is being used. Large or very

deep objects may not be accurately measured.

The LCD indicates the probable identication of all

targets, whether announced by an audio response

or not.

The 0 to 12 Scale is an aid when setting the Detec-

tion Depth (Sensitivity) control. (Do not confuse with

the Coin Depth reading). This scale also provides

target information based on conductivity of the metal

detected, information that will become more valuable

as you gain experience. Conduct tests on metals of

interest to learn approximate readings for the various

denominations.

TOUCHPADS

1. POWER - Press the POWER touchpad once to

turn the CX Plus on. It automatically begins operat-

ing in the Discrimination Mode. Press the pad again

and the detector will shut off. The detector will shut

off automatically when no touchpad is pushed and

no target is detected for about 10 minutes.

2. ALL-METAL - This touchpad serves a dual func-

tion. When pressed and released, it places the de-

tector in its ALL METAL mode of operation. When

www.garrett.com

Master Hunter® CX Plus Owner’s Manual 15

pressed and held rmly, its Fast Track function is

activated. As you begin scanning with the search-

coil in a normal manner, ground balance adjustment

is quickly and automatically achieved. Repeat this

procedure at any time to achieve precise ground bal-

ance.

3. PINPOINT / DEPTH - Press and hold to activate

the pinpointing function of your Master Hunter CX

Plus after you have discovered a target. A com-

plete discussion of pinpointing can be found in this

owner’s manual. After you have pinpointed a target

and released this touchpad, the display will indicate

how far coin-sized targets lie beneath the bottom of

the searchcoil and the reading will be highly accurate

regardless of the size coil being used. This reading

holds for approximately three (3) seconds.

4. DISC - Press DISC (Discriminate) to return to the

Discriminate Mode when you have been operating in

the All Metal Mode. The CX Plus begins operating in

the Discriminate mode whenever it is turned on.

5. + and - - These two similar pads with arrowheads

(at extreme right of the console) are used to regulate

the Audio Threshold and Detection Depth (sensitiv-

ity). If either + or - is pressed, the sensitivity in the

current operating mode will be changed. To change

the audio threshold, press and hold the All Metal

touchpad while regulating the threshold by pressing

the + or - pad.

Special Note: Don’t ever worry about “damaging”

the circuitry of your CX Plus by adjustments that you

make. Just hold down the All Metal touchpad and

press the DISC touchpad to restore factory settings.

CONTROL FUNCTIONS - SIDE PANEL

It is recommended that you begin hunting with both

controls set at the Initial Setting (>) indicators.

1. FERROUS RANGE - Allows adjustment for the

elimination of targets in the iron range up to but not

including aluminum pulltabs. Targets located and

accepted in this range will cause your audio signal

to grow louder.

2. NON-FERROUS RANGE - Allows adjustment for

elimination of targets in the range of pulltabs through

aluminum screw caps.

Garrett’s Target Elimination controls permit you

to select the targets you desire. Furthermore, the

Multi-Range Discrimination System permits selec-

tion of these targets in both Ferrous and Non-Ferrous

ranges. The Ferrous control is adjustable from zero

through bottlecap rejection while the Non-Ferrous

control takes over at pulltab rejection and is adjust-

able through aluminum screw tops. Proper use of

the two controls will dramatically improve accuracy

by eliminating worthless targets in both the ferrous

and non-ferrous ranges and in accepting many kinds

of gold and silver rings, jewelry and coins.

OPERATING INSTRUCTIONS

Discriminate Mode

Whenever you turn on your Master Hunter CX Plus

by pressing the POWER touchpad, you have activat-

ed the Discriminate (trash elimination) mode. When

operating in this mode, the CX detects only selected

metal objects.

Garrett’s two Multi-Range Discrimination controls

permit you to select targets you desire. The follow-

ing settings are marked on the ferrous controls:

• Nails setting will eliminate rusty iron and iron nails.

• Foil setting will eliminate iron, nails and foil. Salt

water will be eliminated near this setting.

• Bottlecaps setting will eliminate steel bottlecaps,

plus iron, nails and foil.

• Nickel setting will eliminate that metal and coins

made of it, plus bottlecaps, iron, nails and foil.

On the Non-Ferrous control knob the settings for

pulltab, screw top, zinc penny and at screwtop indi-

cate the items which will be excluded from detection.

Remember that the elimination is cumulative, i.e. all

items to the left of the pointer will be excluded. Test

typical trash items before taking your Master Hunter

CX Plus into the eld.

Setting the Multi-Range Discrimination controls at

higher settings will cause some rings and coins to

escape detection. Therefore, it is recommended that

you never rotate these knobs any farther clockwise

than necessary. Fill rotation counterclockwise (to the

left) will cause most metallic targets to be accepted.

As the knob is turned farther clockwise (to the right)

more targets will be rejected. As you become famil-

iar with your targets through bench testing, you can

remember the rejection settings of your detector by

the numbers on the controls.
