ABOUT YOUR DETECTOR

Your CZ-3D is an extremely advanced and sophisticated

instrument. It is maximized for a very speciﬁc function - ﬁnding

& properly identifying older era coins at older sites. Simply

select the "enhance mode" with the utilization of the "salt/

enhance" switch to ﬁnd more rare coins!

The CZ-3D was designed to ﬁnd more good metals such as

brass, bronze, copper, silver, and certain gold: reporting it

as a high tone. In addition, a fourth tone has been added to

distinguish between the midtone heard on round & square

"pull tabs" and foil - this enhances your ability to recover gold

jewelry.

With this detector, performance and ID can be further

enhanced by a slower coil sweep speed, more so than previous

CZ models, especially in trashy areas.

Read this instruction manual thoroughly, practice often and

you will be ready for some exciting treasure hunting. Drop us

a line if you have any questions, comments or good ﬁnds to tell

us about. In the meantime...

Happy Hunting!

FACTORY PRE-SET “TURN-ON-AND-GO” MARKS

Your CZ-3D is fairly simple to operate, especially when compared

to other target ID machines. Even so, we strongly recommend that

you read this entire manual. You’ll be able to tune your CZ-3D to

your speciﬁc needs and conditions. A good understanding what

to do and why will lead you to more ﬁnds.

If you can’t wait any longer, and you’re an experienced detector

user, here’s some quick instructions to get you going:

1. Set all the controls to the red numbered

“Turn-On-And-Go” marks:

GROUND = 5

DISC = 4

SENSITIVITY = 3

MODE = ENHANCE

VOLUME = 5

This puts you in a “coins-only” mode and you’re

ready to start searching. Keep in mind that the

GROUND setting of 5 is probably not the optimum

setting for the ground you’re searching and that’s

why the sensitivity level is set low—to reduce false

signals caused by ground mineralization.

2. If you’re using headphones, adjust the volume

controls for a comfortable volume when the coil is

passed over a large shallow object.

3. Walk slowly, overlap your sweeps and keep the

search coil moving. Remember you are in a “motion”

search mode and the coil must be moving at least

slightly to detect a target.

4. When you get a good, repeatable signal, pinpoint

the target by placing the coil on the ground away

from the target, pushing and holding the pinpoint

button and then bringing the coil back over the

target.

5. Once you’ve pinpointed the target, note the

approximate depth reading on the meter, then

identify it by releasing the pinpoint button and

moving the coil side to side in short strokes over

the target. The meter needle will lock onto the

appropriate target classiﬁcation.

6. Happy Hunting!

CONDENSED OPERATING INSTRUCTIONS

SETTING UP

The CZ-3D comes to you just about ready to use. Take a look at the

diagram above and familiarize yourself with the parts of the CZ-3D

before proceeding.

1. Unpack your new CZ-3D carefully. Save the carton

and inserts for future storage or shipment.

2. Take a look inside the locknut on the upper stem.

Note the clear plastic locking pad on the left hand

side and loosen the lock nut by rotating it fully

counterclockwise.

3. Slip the lower stem into the center section.

4. Adjust the stem length (using the guide pin & stem

lock nut) and the coil angle (using the nylon wing

nut) so the search coil rests ﬂat on the ground about

6 inches in front of, and slightly to the right of your

right foot, (to the left of your left foot for left handers).

Your arm should be straight and relaxed, with the

grip held loosely.

REMEMBER: The longer the shaft, the more you will

have to bend your elbow and the sooner your arm

will get tired. The CZ-3D is balanced for comfortable

searching in a tight semicircle around the front of the

operator.

5. With the stem length properly adjusted, wrap the

loop cable tightly around the center section stem

and secure it with the two Velcro straps. Connect

the cable connector to the control housing.

CAUTION: Make sure that the cable is not pulled tight

at the control housing and that you have enough slack

at the search coil to adjust it to any angle.

6. With the shaft length and coil angle properly

adjusted, you should be able to move into your

“search” position (as shown in illustration below) by

leaning forward very slightly and raising your arm (still

straight) until the search coil is about 2 inches above

the ground and 12 inches in front of your foot. The

search coil should be parallel to the ground and may

have to be slightly readjusted at this point.

Figure 2. SEARCH POSITION.

Adjust the stem length and coil

angle so the coil rests ﬂat on

the ground about 6 to 12 inches

in front of your foot. Move

into your “search” position by

leaning forward slightly and

raising the coil about 2 inches

off the ground. This should put

the search coil out about 12 to

18 inches in front of your foot.

SETTING UP

1. GROUND: Used to electronically cancel the effects

of ground mineralization. Proper use of this control

will minimize false ground signals and insure that the

CZ-3D is operating at its maximum potential in just

about any ground condition including wet ocean

sand.

2. DISC: In the 0 through 6 position the CZ-3D is in

the target ID mode, which is a silent, no-threshold,

motion-discrimination mode of operation with the

ability to identify and then ignore (“reject”) or accept

many kinds of small metal targets. In the AUTOTUNE

position, the CZ-3D is in an all-metal mode. In this

mode, the CZ-3D has a wider and deeper search

pattern, however, it lacks the ability to discriminate

HIPMOUNTING

1. Disconnect the cable from the control housing and

unwind all but the last twelve inches from the stem.

Secure the lower end of the cable with a Velcro strap

at least twelve inches up from the coil.

2. Slide the control housing off the handle by holding

the handgrip with one hand and pulling the housing

towards you with the other hand.

3. Reconnect the cable to the control housing. It is

especially important that the cable connector

be installed tightly to prevent false signals during

hipmount use. Tight, but never tightened with

anything but your hands.

4. Put your belt through the slots on the underside of

the housing.

5. Left handers should wear the housing on their right

hip and right handers on their left hip.

NOTE: If you’re working in shallow water you may want

to hang the control housing around your neck or chest-

mount with Fisher’s Chest Harness. Just make sure

you put it in a heavy plastic bag sealed tightly around

the cable. Remember, the only thing waterproof about

the CZ-3D is the search coil.

CONTROL PANEL

or identify targets.

3. PINPOINT/DEPTH READING: A three purpose, spring

loaded push-button. When pushed and held, the

CZ-3D goes into a no-motion, all-metal mode for

precise pinpointing and approximate depth reading

of coin-sized targets. This button is also used in

conjunction with the GROUND control during the

ground balancing procedure.

4. SENSITIVITY/BATT TEST: In the extreme counter-

clockwise position, the battery condition is checked

as indicated by a strong or weak tone and a meter

reading. When rotated clockwise, sensitivity to targets

(as well as ground mineralization and electrical

interference) is increased. When in the AUTOTUNE

mode, this control also acts as a “threshold tone”

control.

5. HEADPHONES: This connector accepts most stereo

headphones.

6. MODE: ENHANCE position for dry land or shallow fresh

water hunting. SALT position for wet-sand ocean

beaches or hunting in shallow surf.

7. VOLUME/OFF: Power on-off and volume control.

Volume is gradually increased from 1 to 5 settings. From

5 to 10, loud target response is held constant while faint

targets continue to get louder (audio boost).

CONTROL PANEL

Figure 3, CONTROL PANEL

3 4 5

When your CZ-3D is properly “ground balanced,” it will have only

a minimum response to ground mineralization. Precise adjustment

of the ground control is critical. The higher the degree of ground

mineralization or sensitivity setting, the more critical it is. Once you

adjust it in either the Autotune mode or Target ID mode, you can

switch back and forth between the two modes without resetting

it, unless you increase the sensitivity level or go from dry sand

to wet sand or vice versa. You should also recheck your setting

occasionally as you search since ground conditions often change

rapidly.

If you have difﬁculty ground balancing, try reducing your sensitivity

level or moving to another spot just in case you are over a buried

piece of metal. In some areas of high ground mineralization you may

not be able to use the “pushbutton” method.

1. Set your controls as follows:

GROUND = 10

DISC = 0 for normal use in target ID mode. (Set DISC

to “Auto tune” for deep search, all-metal Auto tune

mode.

SENSITIVITY = 10

MODE =ENHANCE

VOLUME = OFF

2. Hold the search coil waist high, away from any nearby

metal.

3. Turn the VOLUME control to 10. A brief bell tone is

normal when you turn the VOLUME control on.

If you’re in the Auto tune Mode, you’ll hear an audio

“threshold” hum. Lower the SENSITIVITY control until

you can just barely hear it.

4. If you’re wearing headphones, reduce the headphone

volume controls to a comfortable level when the search

coil is passed over a large, shallow target.

GROUND BALANCING

TURN ON PROCEDURE

“BOBBING” THE SEARCH COIL METHOD

This method takes a little more practice, but you may ﬁnd it slightly

more accurate with fewer false signals from ground minerals.

“PUSHBUTTON” GROUND BALANCE METHOD

This will probably be your method of choice in all but the most

difﬁcult of ground conditions. It’s fast, easy and accurate. You can

use this method in either the Autotune or Target ID mode.

1. With your controls set as in the “Turn-On” procedure,

(GROUND control at 10), hold the search coil parallel

to and 6 to 12 inches off the ground. Press the

PINPOINT button and hold it until you’ve completed

step 2. Make sure you’re at least three feet away

from any metal objects.

2. Still pressing the PINPOINT button, lower the coil to the

ground. Starting at 10, rotate the GROUND control

clockwise until you hear an audio tone. Then back

it off to the exact point where the tone disappears.

Release the PINPOINT button and you’re ready to

search.

NOTES:

1. If you get an audio response as you ﬁrst lower the coil with the

GROUND control at 10, you’re probably over a piece of metal.

Move and try again.

2. If you get a sudden belltone not proceeded by an increasing

audio response as you lower the coil, you’re probably in some

very highly mineralized soil or sand. In this case, it’s best to use

the “Bobbing” method.

3. If you don’t get any audio response, or just a very faint one

as you rotate the GROUND control from 10 all the way to 0,

you’re probably in an area where there’s very little ground

mineralization. Just leave the GROUND control at 10 and

begin searching.

4. Recheck your ground balance occasionally and make sure you

haven’t accidentally moved the MODE switch.
