ABOUT YOUR DETECTOR
Your CZ-5 Quicksilver is an extremely advanced and sophisticated
instrument.
VISUAL TARGET IDENTIFICATION. An easy-to-read meter
displayssevensmall-targetcategories.Silverandgoldbands
across the top indicate the most likely categories for small
gold and silver targets. When the dual frequency CZ-5
classificationcircuitrymakes identification, the needle locks
over the center of the appropriate category. If ID is difficult
due to irregular size, conductivity or depth, the CZ-5 will
alert you to this by jumping back and forth between the
most likely categories. What it will never do is lock-on
between categories or gives you a series of numbers to
interpret. No programming, no razzle-dazzle, no nonsense.
AUDIO TARGET IDENTIFICATION. A low tone means a ferrous
or iron target: a medium tone indicates a pull-tab or foil;
and a high tone means you’ve probably found a coin. The
tone ID always agrees with the meter ID. If the audio
response tone is low, the meter will always read “iron” and
if the tone is high, the meter will always read in one of the
coin categories.
PUSHBUTTON DEPTH READING, VCO PINPOINTING. Just push
a button and the volume, pitch and meter needle will rise
as you approach your target and then peak right over it.
Themetergives you a depth readingininchesforcoin-sized
objects.
WET SAND OPERATION. Salt water is no problem for the CZ-
5. Just flip a switch, reset your ground control and search
that wet sand you never could before, in fact you can
submerge the coil in salt water and search as though it
wasn’t even there. The CZ-5 compensates for salt and sand
simultaneously.
TARGET SEPARATION. It’s a sad but true fact that most gold
rings,pulltabs,foilandnickelsfallintothesameconductivity
range, meaning that a detector user has to dig a lot of
trash to find any rings or nickels. But not any more. The CZ-5
not only separates the nickels from the trash, but the tabs
from the tabs. It has a separate ID and discrimination
categoriesforround pull tabs, rectangular pulltabs,foiland
nickels. Rather than a complicated “notch” system, the
individual categories are sequentially arranged to insure
maximum good target recovery, In a moderately trashy
area for example, you can set the CZ-5 to reject iron and

round pull tabs and still dig nickels and other coins and all
gold rings falling into the nickel, foil and rectangular tab
and nickel categories.
BIG TARGET ALERT. Large shallow (like a jar lid or a beer
can) overload metal detector curcuits making accurate
target ID or trash rejection impossible. But not with the
CZ-5. Whenever it passes over a large shallow target, a
distictive bell-tone immediately warns you that the target is
too large to identify.
DEPTH. Target identification in air is easly for just about any
ID metal detector. But the CZ-5 does it in the ground and
doesitdeeper.ThankstothepatentedFourierDomainSignal
Analysis System, the CZ-5 can identify deeper targets in
mineralized soil. Two VLF ground compensation signals are
transmitted (one at 5KHz, one at 15 KHz), giving the circuitry
two ground compensated target response signals to
analyze, compare and identify.
SILENT SEARCH, SLOW MOTION DISCRIMINATION. No
threshold, no clicking, no popping, no static. Once you set
the CZ-5 discrimination control to one of its six factory
calibratedlock-ondiscriminationpoints, theaudioandvisual
targetidentificationcurcuitswillcompletelyignoreeverything
identifiedasbelonginginacategorybelowthatdiscrimination
point. For example, a setting of “4” tunes out iron, pull tabs
and foil. As long as you’re at this discrimination point you’ll
never hear the low “iron” tone or the medium tone of pull-
tabs and foil. And since the discrimination categories are
exactlythesameasthemetercategories,themeterwillnever
ID iron, pull tabs or foil as long as you remain at “4”. Any false
signal you do hear or see will be in the “coins” category only
because the CZ-5 couldn’t positively identify the target as
iron, foil or a pull-tab.
AUDIO BOOST VOLUME CONTROL. The lower range of this
volume control is like any other you’ve ever used. But as
you increase it above mid-range, loud, shallow target
responseremains at a fixedvolumewhilefaint, deep target
sounds continue to get louder.
PUSHBUTTON MANUAL GROUND ADJUST. It’snosecretthat a
metal detector will perform its very best when manually
tunedforactualon-sitegroundconditions. The onlyproblem
is that manual adjustments have always been confusing,
complicated and time consuming. But not with the CZ-5.
Just push the PINPOINT button and lower the coil to the

ground.ThensettheGROUNDcontroljustbelowathreshold
tone and you’re ready to search.
EASY TO USE. Just pick it up, set the controls on the red
marksandstartsearchingina“coinsonly”mode.Itcouldn’t
be simpler. Or for a maximum performance you can easily
adjust the controls to your own particular situation.
SPIDER COIL. The eight-inch, open center Spider coil makes
pinpointingeveneasier.It’slightweight,tough,Electro-Static
Insulated (E.S.I. Shielded) and 100% waterproof.
TWO SEARCH MODES. A VLF-slow-motion discrimination
mode for target identification and trash rejection. And a
super hot, wide-scan auto tune mode for deep search all-
metal treasure hunting and prospecting.
DROP-IN BATTERIES. No wires, no clips, no battery packs.
Just drop in two 9V transistor batteries.
COMPACT. The CZ-5 breaks down and fits into an optional
carrying case small enough to carry on most airlines.
HIP MOUNTABLE. Just slide the control housing off the shaft
and onto your belt. What’s left is so light it will feel like a
part of your arm.
DOUBLE LOCKING NON-METALIC LOWER POLE. No shake no
wobbles. No “lock-ring” to lose and no metal parts near
the search coil.
LIGHTWEIGHT, BALANCED AND COMFORTABLE. Only three

“S” handle and built-in detector stand.

ABOUT YOUR DETECTOR

FACTORY PRE-SET TURN-ON-AND-GO’ MARKS
Your CZ-5 QuickSilver 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-5 to your specific needs and conditions. And if you have a
good understanding of how to do it and why, you’ll find more.
But if you just 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 “Turn-On-And-Go” marks:
GROUND = 5
DISC = 4
SENSITIVITY = 2
MODE = NORMAL
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. Good Hunting.

SETTING UP
TheCZ-5comestoyoujustaboutreadytouse.Theonlyadjustment
required is the angle of the stem. You may also wish to adjust the
widthofthearmrest.Takealookatthediagramaboveandfamiliarize
yourself with the parts of the CZ-5 before proceeding.
1. Unpack your new CZ-5 carefully. Save the carton
and inserts—they may come in handy for future
storageor shipment.
2. Take a look inside the locknut on the upper stem.
Note the yellow locking pad on the left hand side
and loosen the locking nut by rotating it fully
counterclockwise.
3. Slipthelowerstemintotheupperstem;makingsure
the flat side of the stem is aligned with the locking
pad inside the locknut.
4. Adjust the stem length (using the locknut) and the
coil angle (using the nylon wing nut) so the search
coil rests flat on the ground about 6 inches in front of,
andslightly totherightofyourrightfoot, (tothe leftof
your left foot for left handers). Your arm should be
straight and relaxed, the grip held loosely.

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
leaningforwardvery slightlyandraising yourarm (still
straight) until the search coil is about 2 inches above
the ground and 12 inches in front of your foot. The
searchcoil shouldbe paralleltothegroundandmay
have to be slightly readjusted at this point.
7. If the armrest is too wide or narrow, you may bend
it slightly inward or outward to meet your exact
requirements.
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 “seach” 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.

minimizefalse groundsignals andinsure thatthe CZ-5
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-5 is in the
target ID mode, which is a silent, no-threshold
motion-discrimination mode of operation with the
abilityto identifyandthenignore(“reject”)oraccept
many kinds of small metal targets. In the AUTOTUNE
position,theCZ-5isinanall-metalmode.Inthismode,
the CZ-5 has a wider and deeper search pattern;
however, it lacks the ability to discriminate or identify
andrejecttargets.
HIPMOUNTING
1.Disconnectthecablefrom thecontrolhousingand
unwind all but the last twelve inches or so from the
stem.Securethelowerend ofthecable withaVelcro
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
anythingbut yourhands.
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.
Ifyou’reworking inshallowwater youmay want to
hang the control housing around your neck or
chest-mountwith Fisher’sChest Harness.Just make
sureyouput it in aheavy plastic bag sealedtightly
around the cable. Remember, the only thing
waterproof about the CZ-5 is the search coil.
