ABOUT YOUR DETECTOR

Your CZ-5 Quicksilver is an extremely advanced and sophisticated

instrument.

VISUAL TARGET IDENTIFICATION. An easy-to-read meter
displays seven small-target categories. Silver and gold bands
across the top indicate the most likely categories for small
gold and silver targets. When the dual frequency CZ-5
classification circuitry makes 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.
The meter gives you a depth reading in inches for coin-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, pull tabs, foil and nickels fall into the same conductivity
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
categories for round pull tabs, rectangular pull tabs, foil and
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
does it deeper. Thanks to the patented Fourier Domain Signal
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
calibrated lock-on discrimination points, the audio and visual
target identification curcuits will completely ignore everything
identified as belonging in a category below that discrimination
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 pull­tabs and foil. And since the discrimination categories are
exactly the same as the meter categories, the meter will never
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
response remains at a fixed volume while faint, deep target
sounds continue to get louder.
PUSHBUTTON MANUAL GROUND ADJUST. It’s no secret that a
metal detector will perform its very best when manually
tuned for actual on-site ground conditions. The only problem
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

3

ground. Then set the GROUND control just below a threshold
tone and you’re ready to search.
EASY TO USE. Just pick it up, set the controls on the red
marks and start searching in a “coins only” mode. It couldn’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
pinpointing even easier. It’s lightweight, 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 all­metal 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
and 1/2 pounds light with a cushioned arm rest, foam grip,
“S” handle and built-in detector stand.

Read this instruction manual thoroughly, practice often and you’re in
for some exciting treasure hunting. Drop us a line if you have any questions,

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

The CZ-5 comes to you just about ready to use. The only adjustment
required is the angle of the stem. You may also wish to adjust the
width of the armrest. Take a look at the diagram above and familiarize
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
storage or 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. Slip the lower stem into the upper stem; making sure
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,
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, 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-5 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 upper 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.

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.

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-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
ability to identify and then ignore (“reject”) or accept
many kinds of small metal targets. In the AUTOTUNE
position, the CZ-5 is in an all-metal mode. In this mode,
the CZ-5 has a wider and deeper search pattern;
however, it lacks the ability to discriminate or identify
and reject targets.

HIPMOUNTING

1. Disconnect the cable from the control housing and

unwind all but the last twelve inches or so 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.

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-5 is the search coil.

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

loaded push-button. When pushed and held, the
CZ-5 goes into a no-motion, all-metal mode for precise
pinpointing and approximate depth reading of coin­sized targets. This button is also used in conjunction
with the GROUND control during the ground balancing
procedure.

4. SENSITIVITY/BATT TEST: In the extreme counter­clockwise 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: NORMAL 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.

When your CZ-5 QuickSilver 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 = NORMAL (Unless you’re on a wet ocean

beach, in which case set the MODE switch
to SALT.)

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

10

“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, paying particular
attention to the notes under paragraph 7.

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.

11

“BOBBING” THE SEARCH COIL METHOD

This method takes a little more practice, but you may find it
slightly more accurate (fewer false signals from ground minerals)
in very highly mineralized ground (as in the note above), or if
you are searching in the Autotone mode.

1. Set as in the “Turn-On” procedure, making sure the
DISC control is at AUTOTUNE and the SENSITIVITY control
is set so you can just barely hear a threshold hum.
Hold the search coil parallel to and 6 to 12 inches
over the ground and at least three feet away from
any metal objects. Do not use the PINPOINT button

during any part of this procedure.

2. Lower the coil to an inch or two above the ground
and then quickly raise it. Note that as you lower the
coil, the tone disappears, then gets louder as you raise
it and finally returns to normal when you stop it 6 to 12
inches above the ground.

Conversely, if you set the GROUND control to 1, the
threshold hum will get louder as you lower the coil and
disappear when you raise it.

3. Your objective now is to adjust the GROUND control
so that there is no change, or only a minimum change
in the threshold hum, as you move the coil up and
down. Start by lowering the GROUND control to 9.
Lower the coil and raise it again. One of three things
will happen to your theshold hum:

1) It will fade again as you lower the coil and
increase as you raise it.

2) It will get louder as you lower the coil and go
silent as you raise it.

3) The hum will remain the same, or if it changes
slightly, the change is the same whether you lower
or raise the coil.

4. If the hum remains the same or changes only slightly
as in 3) above, your CZ-5 is properly ground balanced,
and you are ready to begin your search.

5. If the tone fades as you lower the coil as in 1),
continue to lower the ground balance setting in

small

increments until the threshold hum remains the

12

SEARCH MODES

Your CZ-5 has two search modes: Target ID and Autotune. Both
search modes are “motion” modes, meaning the search coil must
be in motion to detect a target.

AUTOTUNE SEARCH MODE

Set the DISC control to Autotune and you’re in a very sensitive,
wide-scan, all-metal, motion search mode. Since this mode

same (or changes very little) as the coil is lowered
and raised.

6. If the hum gets louder as you lower the coil, you
have gone past the correct ground balance
setting. Increase the ground balance level
(rotating the control counterclockwise) in small
increments until there is little or no change in the
threshold level.

7. With a little practice, you should be able to
ground balance quickly by “bobbing” the coil up
and down in a continuous movement as you adjust
the GROUND control with your thumb.

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. 1f you get a sudden bell tone, not preceded by an increasing
audio response, you’re probably in some very highly mineralized
soil or sand. Instead of lowering the coil to an inch or two above
the ground as in step 2 above, stop just before you hear the
bell tone and ground balance as instructed. It will then be
necessary to maintain that coil height as you search.

3. lf you don’t get an audio response, or if the hum stays the
same no matter where you set the GROUND controls as you
bob the coil up and down, you’re probably in an area where
there’s very little ground mineralization. Just leave the
GROUND control at 10 and begin searching.

“BOBBING” THE SEARCH COIL METHOD

responds to all metal targets and does not have the ability to
identify or reject targets, this will probably not be your normal
search mode.

The Autotune mode does have some advantages however

which make it useful to use in at least two situations:

1. Non-Trashy Areas. Since the Autotune mode has
a wider scan than the ID mode, you’re less likely to
miss a good target when using it. Search in the
Autotune mode until you find a target. Pinpoint the
target using the PINPOINT button and then switch
the DISC control to “0” to identify it. The DISC control
is positioned so that you can switch back and forth
between Autotune and “0” with a flick of your
thumb.

2. Highly Mineralized Soil or Sand. The Autotune Mode

is recommended for black or gray sand beaches or
highly mineralized soil. Under these conditions it may
be necessary to lower the Sensitivity level and sweep
several inches off the ground (see the note under
paragraph 7 on page 10). Gold nuggets are generally
found in highly mineralized soil so this will be the search
mode of choice for prospectors.

TARGET ID SEARCH MODE

When the DISC control is set in the 0 through 6 position, the
CZ-5 has the ability to identify many types of small targets and,
depending on the discrimination level, reject or ignore most of
them. To better understand just how your CZ-5 responds to
different targets, try the following:

1. Scatter some sample targets such as coins, rings,
pull tabs, nails and foil on the ground at least 18
inches apart. Include some large targets as well;
jar lids, soda cans, etc.

2. Set the DISC control at “0”, SENSITIVITY at “5”,
MODE at ‘NORMAL’, VOLUME at “10”. (If you’re
wearing headphones, reduce the volume to a

SEARCH MODES

comfortable level when you are over a large target.)

3. Ground balance the CZ-5 as in the “Ground
Balance” procedure.

4. Hold the search coil about two inches above
and parallel to the ground and move it slowly back
and forth across each sample. Remember, the coil
must be in motion to get a response. Keep in mind
that for accurate target ID, the coil center must
pass directly over the target.

5. Note the response you get over the small targets:
For small iron or steel targets, the meter needle will
usually lock in the “IRON” category. Most pull tabs,
foil, nickels and the newer zinc pennies will also be
correctly classified. Silver coins, copper coins, and
the newer clad coins will ID in the highest category.

6. Note that an enlongated ferrous object such as
a nail will give you a double “beep” as you cross it
from end to end and a single “beep” if you cross its
center.

7. Most silver rings will ID at the highest end of the
scale. If you have enough gold rings you will note
that some fall in the round tab category, some in
the “FOIL” category, some in the rectangular
category, a few in the nickel category, and very
few in the remaining coin categories. This is due to
the fact that the combination of size, shape and
conductivity of a particular ring will almost always
add up to a target that is electronically identical
to either a piece of foil, pull tab or nickel. Most
metal detectors have a difficult time separating
gold rings, nickels, tabs, and foil. But, the patented
circuitry of your CZ-5 can easily tell the difference
between nickels and most trash. Better yet, it will
allow you to find many types of gold rings while
completely ignoring at least some types of pull tabs
and small pieces of foil.

8. Note also the different audio responses: an iron
target will give you a low tone, tabs and foil a
medium tone and coins a high tone.

14

SEARCH MODES

15

SEARCH MODES

9. When you go over a large, shallow target the

CZ-5 will respond with a distinctive belltone. This is
due to the fact that metal detectors can only
identify small targets. What usually happens is that
the detector circuits will overload and identify a
large target as “good” (silver, coin, etc.). Your
CZ-5, however, will alert you to the fact that the
target is big and shallow and can not be accurately
identified. (Big deep targets however, will usually
be classified as a coin. Also be aware that large
coins on the surface may set off the bell tone. And
the optional, smaller 5 inch coil is more likely to
overload than the standard 8 inch coil.)

10. You may also note that some rectangular tabs
ID as round tabs and vice versa. Because of the
wide variety of sizes, shapes and conductivity of
the many pull tabs manufactured over the years,
there is overlap as far as identification goes. Small

Figure 4. Typical CZ-5 audio and meter reponses.

16

SEARCH MODES

pieces of tabs or aluminum are often misidentified;
the tail of a round tab for example, may ID as a
nickel. However, most tabs and most of the items
on the CZ-5 meter face will be identified correctly.

11. Now increase the DISC control to “1”. You will
find that the CZ-5 rejects the small iron targets and
no longer responds either with an audio tone or
needle deflection.

12. Continue to increase your DISC control, noting
that with each successive step up you reject more
and more targets. At DISC = 4 for example, you are
in a “coins-only” mode, ignoring iron, tabs and foil
while accepting and identifying nickels, zinc
pennies and silver, clad and copper coins.

13. At the maximum DISC level of 6 the CZ-5 will
ignore most all-small targets except silver, clad and
copper coins.

14. Now switch the DISC control to the AUTOTUNE
position and note the completely different kind of
response. No tone or meter identification, just a
solid, smooth, response over every target.

15. The chart on page 15 shows some of the
responses you may expect over different targets
and at different levels of discrimination. Note that
as you progressively increase the discrimination
level you eliminate more and more targets.

NOTE: Be aware that due to the virtually infinite variety of sizes,
shapes and alloys of many “good” targets (relics, jewelry,
foreign coins, etc.), they may be ID’d as just about anything. For
example, a Civil War mini ball may be ID’d as foil, or a new
Canadian coin as a rectangular pull tab.

17

SEARCHING

Good search techniques are every bit as important as having
a good detector.

1. Make sure your CZ-5 is properly ground balanced
and the MODE switch is in the proper position: SALT
for wet ocean beaches, NORMAL for just about
every other situation.

2. Decide which search mode you’re going to use,

Target I.D. or Auto tune.

Recommended starting

point: Target ID mode with the DISC control set at “4”.

3. Set your SENSITIVITY control. Only experience will
tell you how to set it in every situation but you’ll
probably want to run it as high as you can.

Recommended starting point: SENSITIVITY 5 . If
you’re in the Autotune mode, set it so that you can
just barely hear a slight audio hum.

4. Adjust your VOLUME control. Remember that a
setting above 5 will amplify the response of faint
targets so that they sound like a shallow or large
target. Some searchers prefer not to use it above
5 so that the audio response will give them some
idea as to the depth and/or size of the target.

Recommended starting point: VOLUME = 10, then
if you’re using headphones, adjust the headphone
volume controls for a comfortable, not-too-loud
response over loud targets.

5. Once you’ve got your controls properly set,
begin your search by walking slowly and sweeping
the search coil in a tight semicircle.

6. Keep the coil parallel to the ground and as close

to the ground as practical. This is extremely
important for maximum coverage and depth. If
you’re searching on a lawn, you may set the coil
right on the grass and slightly “scrub” it.

7. Overlap your sweeps by at least 50%. Remember

that your coil’s searchpattern is conical and if you don’t
overlap each sweep you’ll miss the deeper targets.

8. Search in a methodical manner. Pay close

attention to where you’re going and where you’ve

rate. Remember that the CZ-5 is a motion detector
and responds only when the coil (or the target) is
moving (except when in the Pinpoint mode).

10. Take your time. If you walk too fast you can’t
overlap your sweeps and you’ll miss a lot of ground.
If you swing your coil too fast you lose some
sensitivity to deep and/or small targets.

search coil pattern and how it is affected by sweep
speed, ground mineralization and search mode.

Unlike other metal detectors, the discrimination level has little
if any effect on the depth capability of the CZ-5. Note however,
that the all-metal Autotune mode has a wider search pattern
and may detect a little deeper. Depth is also determined by the
size, shape and conductivity of the target as well as the sensitivity
setting of the CZ-5.

a. Very slow or fast sweep speed.
b. Discrimination set at “10.”

PINPOINTING

PUSHBUTTON PINPOINT MODE

Target location is quick and easy using the pushbutton Pinpoint
mode. You do not have to keep the coil moving to get a response
in this mode.

1. Once the presence of a target is indicated by
the “beep-beep” of your CZ-5, simply move the coil
away from the target area, and with the coil lightly
on the ground or very close to it, press and hold the
PINPOINT button. (It doesn’t matter which mode
you’re searching in, Autotune or Target ID.)

2. As you bring the coil back into the target area,
still pressing the PINPOINT button, the audio volume
and pitch will increase and the meter needle will
swing to the right.

3. When the needle, pitch and volume are at their
highest points, stop the coil and move it forward
and backward a couple of times, again stopping
over the strongest response.

4. Repeat one more time, side to side and then front
to back, keeping the PINPOINT button pushed in and
stopping over the spot where you get the maximum
volume, pitch and meter reading. Your target should
be directly below the center of your search coil.
With a little practice, you’ll find that you don’t even
need to look at the meter unless you want a depth
reading.

For quick and accurate pinpointing of strong
signals from large or shallow targets, push and hold
the pinpoint button with the coil very close to the
approximate target area. This will “tune-out” most
of your target so you will only receive a response
directly over or very nearly directly over it. You may
also try reducing the sensitivity level and/or raising
the coil so you can just barely hear the signal.

For very weak signals, make sure you press the
PINPOINT button with the coil completely out of the
target area. You may also try moving the coil closer
to the ground or increasing the sensitivity and
volume levels.

21

TARGET ID MODE AND AUTOTUNE MODE

Pinpointing in either of the search modes is more difficult but
with practice you should be able to get the hang of it. (Many
CZ-5 operators don’t even bother with the Pinpoint mode unless
they want a depth reading.)

Simply use the same basic procedure as you would using the
Pinpoint mode, moving the coil side to side and front to back
over the target area, stopping over the strongest audio response.
The only difference will be that you should use as short of stroke
as possible (four to six inches is plenty) and when you stop the
coil, you will lose the audio signal. You MUST keep the coil moving
at least slightly to determine the location of the strongest signal
before you stop it.

PINPOINTING

22

TARGET IDENTIFICATION

Target ID is quick and simple; just keep in mind these four rules:

1) You must be in the Target ID mode. If you’re searching in
Auto tune, switch over to “0” on your DISC control.

2) For accurate identification, the center of the search coil
must pass directly over the target.

3) There are many good targets, which are not classified by the
CZ-5. As mentioned earlier, gold rings for example may fall in just
about any category except iron. Many foreign coins, especially
the newer ones, may ID as foil or pull tab. Gold nuggets,
depending on their size and shape, may fall into just about any
category, the smaller nuggets falling on the lower half of the
scale. So if you’re not just looking for U.S. coins, you should test
some sample targets to determine what level of discrimination
you want to work at and what targets you want to dig.

4) Your CZ-5 will correctly identify most small targets most of
the time, but it can be fooled. Large targets, uneven ground
mineralization, a good target lying next to a bad target, deep
targets, all of these and more are sources of error. Remember,
the CZ-5 is designed to ID small, coin size targets only, and
even some of these may be deep, bent, damaged, or
corroded enough to give a false signal.

1. Once you’ve located a target, pinpoint its exact
location as in the “Pinpointing” procedure. Since

accurate ID is dependent on accurate pinpointing,
it is recommended that you always press the
PINPOINT button rather than try to pinpoint your
target in either the Autotune or Target ID mode.

2. Once you’ve pinpointed your target, release the
PINPOINT button. If you’re searching in the
Autotune mode, switch over to DISC = 0. If you are
already in the Target ID mode, just leave the DISC
control where it is.

3. Move the coil just enough, left right left, across
the target to get a good signal. The meter needle
should lock onto a target classification, which in
turn will agree with the audio response (high,
medium, or low tone).

4. If you no longer get a meter reading or audio

23

DEPTH READING

Your CZ-5 Quicksilver will give you a quick and approximate
(usually within an inch) depth reading of coin-size targets.

1. Place the search coil lightly on the ground at
least twelve inches away from your target area.

2. Press and hold the PINPOINT button.

3. Still pressing the PINPOINT button, bring the coil

back over the target and pinpoint its location by
stopping the coil over the point where you get
maximum pitch, volume and needle response.

4. Place the search coil lightly on the ground
directly over the target, and still pressing the
PINPOINT button, note the position of the needle
over the depth reading scale. For example, if the
needle is midway between the four inch and six
inch marks, your target is approximately five inches
deep.

You will quickly realize that the depth reading
procedure is just like pinpointing, however there is
one very important difference: when pinpointing
is not real critical where or when you press the
pinpoint button. In fact, it is often desirable to
“detune” your target by pressing the button when
the search coil is very close to your target and
either on the ground or slightly above it. When
taking a depth reading however, it is important that
the coil be placed lightly on the ground at least
twelve inches away from the target (or any other
metal) before pressing the PINPOINT button. Also,
remember that while you can pinpoint just about
any size target, depth reading is only accurate for
coin size targets.

response once you’ve pinpointed the target, then
you’re over something that falls below the DISC
setting you’ve chosen and the CZ-5 is rejecting it.

TARGET IDENTIFICATION

24

Once you have identified and pinpointed a target, your
objective is to recover it quickly and neatly, leaving virtually no
trace of your excavation. There are almost as many ways to do
this, as there are Treasure Hunters. Whatever works for you is
good enough as long as you don’t break any laws, damage
vegetation, or leave uncovered holes.

Generally speaking, beachcombers do little if any damage to
the environment while recovering targets. However, if you plan
to use your CZ-5 on lawns or in parks, your target recovery
method can be very important. Two of the most successful
methods are illustrated in a separate booklet enclosed with your
CZ-5.

Whichever method you choose, remember that responsible
Treasure Hunters take pride in their ability to leave soil and
vegetation intact and undamaged.

TARGET RECOVERY

25

RECOVERY TOOLS

FALSE SIGNALS

A “false signal” occurs when a target is incorrectly identified.
For example, a small broken-off piece of pull-tab may be
identified as a nickel. Or a small deep coin, especially in
mineralized soil, may read “IRON”. The more sensitive the metal
detector, the harder it is not to have false signals. Your CZ-5 is an
extremely sensitive machine so you’re bound to encounter them.
Here are some of the most frequent sources of false signals and
what to do about them:

1. TRASH: The most common source of false signals.
Large or irregular pieces of trash may give positive,
lock-on false signals. In this case you’ll usually have
to dig the target but with experience you’ll be able
to eliminate many of the large targets whose size
will be obvious when you go into the pinpoint
mode.

Another false signal response may be a “one­way” or disappearing signal. You’ll sweep over the
target and get a good signal but nothing on the

1. A heavy duty, blunt screwdriver is commonly
used by expert Treasure Hunters and is the tool of
choice for cut lawns.

2. A sturdy hunting knife with a five inch blade will
do the job on most other soils. A high quality double
edge “survival” knife is an even better (and more
expensive) choice since it will be almost impossible
to bend or break.

CAUTION: Using a jack knife without a locking

blade is a good way to lose a finger!

3. A narrow garden trowel will work in loose or wet soil.

4. Several excellent digging tools are made just for

the Treasure Hunter and especially designed sand
scoops are available for beachcombing.

5. A thin, dull probe is the preferred tool for precise
target location.

26

return sweep. When this happens you’re over a
target that the CZ-5 can’t positively identify due to
its size, shape, depth or alloy. The CZ-5 may ID it as
a coin when swept from one direction and iron on
the return sweep. If your DISC control is set at “0”
you’ll hear first a high tone (coin) and then a low
tone (iron). Or if your DISC control is set higher, to
reject iron, you’ll hear the high tone sweeping one
way and nothing the other way.

Quite often the signal will just disappear and you
won’t be able to find it no matter which direction
you sweep. These one-way and disappearing
signals are usually trash and as a general rule you
should ignore them. If you have any doubts, press
the PINPOINT button to get an accurate location
and then ID the target. If you get a good
repeatable, lock-on ID, dig it. If you still get a one­way signal or it disappears, move on. Also, if your
pinpointing location is different then your ID
location, your target is probably a piece of iron.

Reducing your sensitivity level or increasing the
discrimination level may reduce the number of
false signals caused by trash.

2. DEEP TARGETS: Deep targets, just barely within
the range of the CZ-5 may be misidentified. For
example, a deep coin may ID as iron or a deep
piece of iron may ID as a coin. There’s not much
you can do to avoid this other than to use your
pinpoint mode to insure that you are exactly
centered over the target. Or you may reduce your
sensitivity level so you just ignore the very deepest
targets. Fortunately, misidentification of deep
targets is not what usually happens. It’s the
exception to the rule.

3. ELECTRICAL INTERFERENCE: Constant chatter
caused by radio/TV stations, power lines or nearby
detectors operating at one of the CZ-5 search
frequencies. The best solution is to move away from
the source of the interference. You may also try

FALSE SIGNALS

27

FALSE SIGNALS

one of the following: Switch to the Autotune mode.
Reduce your sensitivity level. Slow down your
sweep speed. Use the optional 5 inch search coil.
If the interference is only minimal and you wish to
continue searching anyway, test your CZ-5 over a
known target to make sure it’s operating properly.
Inside some buildings, electrical interference may
be so bad that you’ll have to go outside just to
bench test your CZ-5.

4. HIGHLY MINERALIZED SOIL: May cause a
belltone response or constant false signals. Check
your ground balance (see the “GROUND
BALANCE” section referring to mineralized soil), and
make sure your MODE switch is in the proper
position. If it is, try switching to the SALT mode and
re-ground balancing. Try lowering the sensitivity
and/or increasing the discrimination level. Search
in the AUTOTUNE mode. Use the optional 5-inch
search coil. Re-ground balance using the
“Bobbing” method. If all else fails, raise the search
coil just high enough for the false signals to
disappear and then sweep at that constant height.

5. BLACK SAND: Same as HIGHLY MINERALIZED SOIL.

6. WET SALT WATER SAND: Your CZ-5 should be able

to handle most wet sand easily unless it’s black (see
BLACK SAND above). Chances are, if you’re having
trouble in wet sand, you forgot to switch your mode
switch to SALT and re-ground balance when you
moved from dry to wet sand.

7. HOT ROCKS: Some rocks, by virtue of their high
mineral content, will be seen by metal detectors
as a metal target.

In the Autotune mode, the CZ-5 will respond to
most hot rocks. Prospectors (who will most likely be
using the Autotune mode in an area where hot
rocks abound), however, will learn to distinguish
between hot rock and nugget sounds. In the target
I.D. mode, certain types of hot rocks will be
automatically rejected at DISC = 0 and virtually all

28

FALSE SIGNALS

other hot rocks will be identified as iron or rejected
at DISC = 1.

8. “END OF SWING”: Silent search motion detectors
often give false signals at the edges of the search
pattern—just as the coil stops and begins
accelerating back toward the operator. If this is a
problem, try one or more of the following: Keep
your sweep smooth, slow and low to the ground.
Check your ground balance. Lower your
sensitivity. Make sure your search coil is properly
secured and the cable connector is firmly
tightened.

9. DIGGING TOOL: If you’re carrying a metal sand
scoop, digging knife, screwdriver or whatever,
hold it behind your back or keep it above your
waist. Your CZ-5 is sensitive enough to sound off
each time you sweep the coil beneath it.

10. ELONGATED FERROUS OBJECTS: If you get two
beeps close together and can’t find either target,
you may be near a nail or some other long, ferrous
object.

Fortunately, in most cases your CZ-5 will identify
these objects correctly, they just won’t be where
you think they are. In all cases, the target will be
between the beeps, or if you sweep at right angles

OPERATING TIPS

1. Use headphones. You’ll hear fewer distracting

sounds and more target sounds. And you’ll find
more.

2. It’s always a good idea to walk slowly and
overlap your sweeps. But if you’re searching large
expanses of new territory you may want to walk a
little faster and not overlap your sweeps as much
until you start making a few good finds. Then, slow
down, overlap your sweeps and cover every inch
if ground.

3. In trashy areas, to reduce the “masking” effects
of trash on nearby good targets, use a shorter and
slower sweep pattern. Also, the optional smaller 5­inch search coil will zero in on good targets closer
to trash.

to your original direction, you’ll receive a single
beep directly over the target.

11. OTHER TARGETS THAT AREN’T THERE: Good lock­on, repeatable signals but nothing there.

a) Shallow coins (at or near the surface) or coins
on edge will give a double beep, one on either
side of the coin, just like a nail. Like the nail, the
coin on edge will give a single beep directly
over the target if you sweep at right angles to
your original direction.
b) A coin lying in the ground at an angle may
give a single target response but may pinpoint
several inches away from its true location. Check
around the inside edges of your hole. If you still
don’t find it, enlarge the hole by a couple of
inches.
c) A large deep target, like a buried pipe or a
manhole cover at two feet, will often give a good
strong coin signal. If you get a depth reading of
four inches and you’ve dug down a foot and
widened your hole several times, give up.

FALSE SIGNALS

30

4. Recheck your ground balance occasionally and

make sure you haven’t accidentally moved the
MODE switch.

5. Here’s a quick and easy way to tell the difference
between a small shallow piece of foil and a gold
ring (or other possibly good target) without digging:
if you get a good solid, “FOIL” ID, set the search
coil down close to the target and then whip it
rapidly across the target just once with what can
best be described as a flick of the wrist. If the target
disappears, it’s probably a small shallow piece of
foil. If not, dig it up—it could be that gold ring you’re
looking for. Practice this over some foil until you
get the hang of it.

6. Don’t be afraid to turn your sensitivity down. True,
the higher the sensitivity, the deeper your CZ-5 will
go and the more you’ll find. But that’s only under
optimum conditions. If you’re getting a lot of false
signals caused by electrical interference, ground
mineralization or dense trash, lower your sensitivity.
If you have to back it down to 4, 3 or even 2 to
eliminate the falsing, do it. That’s what your
SENSITIVITY control is for. You’ll be surprised at how
much you might find in an area that would
otherwise be unsearchable at high sensitivity levels.

7. Set your discrimination at an appropriate level.
If there’s very little trash in the area, set it low, say
at iron discrimination and dig every good signal.
If there is a lot of trash present and you’re mainly
interested in coins, set the discrimination level high—
you may even want to sacrifice nickels and zinc
pennies in extremely trashy areas. If you’re looking
for gold rings, relics, artifacts, or small ancient coins,
you’ll have to set your discrimination level low. The
best way to find out how low is to bury some sample
targets or just dig everything for awhile until you
get a feel for which target classifications will be
the most productive.

8. Look for repeatable signals and don’t waste time
on disappearing or one-way signals. If you hear a

OPERATING TIPS

31

good beep but can’t repeat it when you go back
over the target area, or if it beeps in only one
sweep direction, it’s probably a piece of trash—
something below your discrimination setting.

9. If you’re in a relatively non-trashy area, try
searching in the Autotune mode and then identify
your targets by switching to DISC = 0. You’ll find more
and deeper targets this way.

10. If you’re having any difficulty pinpointing or
identifying a target in the ID mode, don’t waste
any more time. Push the pinpoint button for quick
pinpointing then release it for accurate ID.

11. If your target disappears when you go into the
Pinpoint mode, you’ve probably tuned it out by
pressing the button too close to the target or over
another piece of metal. Try again, this time pushing
the PINPOINT button over another piece of ground.

12. Don’t waste a lot of time digging holes for targets
you can’t find if your hole keeps getting deeper and
wider, cover it up and go on. You may be over a
buried pipe or some other large deep target.

13. When in doubt, dig. If your CZ-5 can’t quite
decide whether a target is good or bad, dig it up.

14. Good things often come in twos. Or even threes.
Once you’ve recovered a good target, always
recheck the hole for a second signal and carefully
search the immediate area by walking slowly
around the hole two or three times, overlapping
your sweeps in an ever widening circle. Always dig

every suspicious sound in the vicinity of a good find.

15. Recheck your hole even if your find was trash.
Good targets are often found beneath the bad ones.

16. Practice. Practice over known targets. Practice
ground balancing. Practice pinpointing. Reread
the appropriate part of this manual if you’re having
problems.

BATTERY REPLACEMENT

Check your batteries frequently by clicking the SENSITIVITY
control counter clockwise into the BATT test position. The
condition of the batteries will be indicated in two ways:

1) An audio tone. The stronger the better. A loud, high-pitched
tone indicates good batteries. A weak, low-pitched tone indicates
weak batteries.

2) A meter reading. Replace the batteries when the needle falls
below gray BATT area. Two nine volt transistor batteries are located
in a compartment at the rear of the housing. When it’s time to
replace them, always use alkalines and always replace both of
them. (You may also use rechargeable Nicads but expect about
1/2 the battery life.)

1. Remove the battery door by loosening the two
captive screws.

2. Tilt the housing slightly and the batteries will slide out.

3. Install the new batteries. Make sure the contact

end goes in first and that you match the polarity
markings on the battery door.

If either or both of the batteries are installed
incorrectly, the CZ-5 will simply not turn on. The
instrument will not be damaged.

4. Snug the screws down tightly—finger tight only. Do
not use a screwdriver or other hand tool.

Figure 9. Battery replacement

33

Your CZ-5 doesn’t require a lot of care. It’s built with high quality
materials but there are a few things you should do to keep it in
peak operating condition.

1. If you’re not going to be using it for a while, take
the batteries out. Acid damage caused by leaking
batteries can be severe.

2. Avoid extreme temperatures. Don’t leave it inside
a closed car sitting in the sun, or even worse, the trunk
of a car.

3. If you “scrub” the search coil on the ground, you’ll
eventually wear through the bottom of the coil.
Replacement coils are expensive. Instead, invest in a
coil cover. They’re cheap.

4. Keep your CZ-5 dry and clean. If you’ve been
working in or around salt water or dust, wipe it down
with a damp cloth and dry it with a hair dryer (low or
no heat) or dry cloth. Remove and clean the lower
stem. Keep the lock nut free of sand and dirt.

TREASURE HUNTER’S CODE OF ETHICS

LETS PRESERVE OUR TREASURED SPORT!

Laws governing the use of metal detectors are becoming
more and more common. In many countries, the use of metal
detectors is illegal or severely restricted. Don’t let this happen in
your area.

ALWAYS get permission to hunt on private property.
ALWAYS leave a site cleaner than you found it. Take at least

some trash with you or, if you can, take it all.
ALWAYS fill in your holes neatly whether you’re in a city park or
remote wildernessness. Leave the land as it was before you
disturbed it.

ALWAYS obey all laws relating to Treasure Hunting.
ALWAYS return valuable property if you can locate the original

owner.
ALWAYS do whatever you can to give the hobby of Treasure
Hunting the good image it needs and deserves.

Where To Use Your Metal Detector In The U.S.

National Forest and Federal Lands—Metal detecting is allowed

only by special permit acquired from the federal government.
Each area has a district office.
Corps of Engineers, Lakes, Shorelines and Lands—Permission has
been granted only on predisturbed sites, such as beaches and
attached swimming areas. New Corps lakes and lands must be
okayed by the main office of the Army Corps of Engineers. Each
area has a district office.
State Parks and Lands—Some state parks are open to metal
detecting, but some are not. Always check with the park ranger
before attempting to use your detector.
Bureau of Land Management (BLM) Lands—Some areas are
open for metal detecting, and some are not. Always check with
the district office.
City or County Park Lands—Most are open to metal detecting
unless notice is given by a sign or city ordinance. When in doubt,
always check with the city’s Parks and Recreation Department.
Public School Grounds—Most are open to metal detecting unless
notice is given by a sign, city ordinance, law enforcement official,
or school employee. You should always check with the school
office first.
Privately Owned Lands (Private Property)—Permission required.
And it is always best to have the permission in writing.
Historically Marked Lands or Sites—Metal detecting is not
allowed. Don’t even think about it.
