Your CZ-3D is an extremely advanced and sophisticated
instrument. It is maximized for a very specic function - nding
& properly identifying older era coins at older sites. Simply
select the "enhance mode" with the utilization of the "salt/
enhance" switch to nd more rare coins!
The CZ-3D was designed to nd 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 nds to tell
us about. In the meantime...




Happy Hunting!

1 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. Youll be able to tune your CZ-3D to
your specic needs and conditions. A good understanding what
to do and why will lead you to more nds.
If you cant wait any longer, and youre an experienced detector
user, heres 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 youre
ready to start searching. Keep in mind that the
GROUND setting of 5 is probably not the optimum
setting for the ground youre searching and thats
why the sensitivity level is set lowto reduce false
signals caused by ground mineralization.
2.

If youre 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 youve 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 classication.

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 at 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 at 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 5
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.
