ABOUT YOUR DETECTOR
Your CZ-5 QuickSilver is an extremely advanced and sophisticated
instrument. Here are some important built-in features:
1. 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
over the center of the appropriate category. If ID is difficult
due to irregular size, conductivity or depth, the CZ-5 will
alert you by jumping back and forth between the most likely
categories. What it will
categories or gives you a series of numbers to interpret. No
programming, no razzle-dazzle, no nonsense.
2. 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
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.
3. 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.
4. WET SAND OPERATION. Salt water is no problem for the CZ-
5. Just flip a switch, reset your ground control and search.
The CZ-5 compensates for salt and sand simultaneously.
5. TARGET SEPARATION. It’s a sad but true fact that most gold
rings, pull tabs, foil and nickels fall into the same conductivity
range. In the past a detector user had 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.

ABOUT YOUR DETECTOR
6. BIG TARGET ALERT. Large shallow items, like a jar lid or a
beer can, overload metal detector circuits 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.
7. 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.
transmitted (one at 5KHz, one at 15 KHz), giving the circuitry
two ground compensated target response signals to
analyze, compare and identify.
8. 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 circuits 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.
9. AUDIO BOOST VOLUME CONTROL. The lower range of this
volume control is like any other you’ve ever used. As you
increase it above mid-range, loud, shallow target responses
remain at a fixed volume while faint, deep target sounds
continue to get louder.
10. 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
ground. Then set the GROUND control just below a threshold
tone and you’re ready to search.

11. 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.
12. 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.
13. TWO SEARCH MODES. The VLF, slow-motion discrimination
mode is made for target identification and trash rejection.
The super hot, wide-scan, autotune mode is ideal for deep
search, all-metal treasure hunting and prospecting.
14. DROP-IN BATTERIES. No wires, no clips, no battery packs.
Just drop in two 9V transistor batteries.
15. COMPACT. The CZ-5 breaks down and fits into an optional
carrying case small enough to carry on most airlines.
16. 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.
17. DOUBLE LOCKING NON-METALIC LOWER POLE. No shake no
wobbles. No “lock-ring” to lose and no metal parts near
the search coil.
18. 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.

CONDENSED OPERATING INSTRUCTIONS
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. If you have a good
understanding of how to do it and why, you’ll find more.
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 “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.

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 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 lock nut by rotating it fully
counterclockwise.
3. Slip the lower stem into the upper stem. Make 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, with the grip held loosely.

SETTING UP
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.

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.
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 chestmount 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.

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, motiondiscrimination 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 CZ5 has a wider and deeper search pattern, however,
it lacks the ability to discriminate or identify and
therefore reject targets.

TURN ON PROCEDURE
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
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,
level or go from dry sand to wet sand or vice versa.
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.
unless you increase the sensitivity
You should

“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.
10
“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.
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.
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:
a) It will fade again as you lower the coil and increase
as you raise it. Continue to lower the ground

threshold hum remains the same (or changes
very little) as the coil is lowered and raised.
b) It will get louder as you lower the coil and go silent
as you raise it.
c) The hum will remain the same, or if it changes slightly,
the change is the same whether you lower or raise
the coil. Your CZ-5 is properly ground balanced, and
you are ready to begin your search.

You have gone
11
“BOBBING” THE SEARCH COIL METHOD
until there is little or no change in the threshold
level.
4. 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. If 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.
SEARCH MODES
Your CZ-5 has two search modes: 1) Target ID and 2) 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 for a very sensitive, widescan, all-metal, motion search mode. Since this mode responds
12
SEARCH MODES
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. 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 comfortable
level when you are over a large target.
3. Ground balance the CZ-5 as in the “Ground
Balance” procedure (See pages 9 & 10).

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.

10. You may also note that some rectangular tabs ID
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

be classified as a coin. Also, be aware that large
coins on the surface may set off the bell tone. The

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 pieces
of tabs or aluminum are often misidentified. The tail
of a round tab for example, may ID as a nickel.

longer responds either with an audio tone or

different levels of discrimination. As you
progressively increase the discrimination level, you
eliminate more and more targets.
NOTE: Due to the virtually infinite variety of sizes, shapes and
alloys of many “good” targets (relics, jewelry, foreign coins,
etc.), they may be misidentified. For example, a Civil War mini
ball may be identified as foil, or a new Canadian coin as a
rectangular pull tab.

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 ID or Autotune.
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 they sound like a shallow or large target.
Some searchers prefer not to use it above 5 so the
audio response will give them some idea as to the
depth and/or size of the target.
starting point: VOLUME = 10. 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 search pattern 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

Remember that the CZ-5 is a motion detector and
responds only when the coil (or the target) is moving
(except 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.
11. Figure 7 on the next page shows the CZ-5 search
coil pattern and how it is affected by sweep speed,
ground mineralization and search mode.

parallel and close to the
ground at all times.

Figure 7. Search coil
detection pattern
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.
19
PINPOINTING
PUSHBUTTON PINPOINT MODE
Target location is quick and easy using the push-button 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 receive a response directly
over it. You may also try reducing the sensitivity level
and/or raising the coil so you can 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.
20
PINPOINTING
TARGET ID AND AUTOTUNE MODES
Pinpointing in either of the search modes is difficult and requires
practice. 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.
In Target ID or Autotune, simply use the same basic procedure
for 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 is that you should use as short a
stroke as possible (4 to 6 inches is plenty). 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.
TARGET IDENTIFICATION
Target ID with the CZ-5 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, and
deep targets, 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.
21
TARGET IDENTIFICATION
1. Once you’ve located a target, pinpoint its exact
location as in the “Pinpointing” procedure.
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
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.
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
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
Since
across the target just once with what can
22
TARGET IDENTIFICATION
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
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.
23
DEPTH READING
Your CZ-5 Quicksilver will give you a quick and approximate
depth reading of coin-size targets, usually within an inch.
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,
where or when you press the pinpoint button is not
real critical. 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.
24
TARGET RECOVERY
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.
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.
4. When in doubt, dig. If your CZ-5 can’t quite decide
whether a target is good or bad, dig it up.
5. 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.
every suspicious sound in the vicinity of a good find.
6. Recheck your hole even if your find was trash. Good
targets are often found beneath the bad ones.
Always dig
25
TARGET RECOVERY
7. Practice. Practice over known targets. Practice
ground balancing. Practice pinpointing. Reread
the appropriate part of this manual if you’re having
problems.
Whichever method you choose, remember that responsible
treasure hunters take pride in their ability to leave soil and
vegetation intact and undamaged.
RECOVERY TOOLS
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:
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.
Using a jack knife without a locking
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
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:
not
to have false signals. Your CZ-5 is an
26
FALSE SIGNALS
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
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 one-way signal or it disappears, move
on. Also, if your pinpointing location is different than
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
27
FALSE SIGNALS
pinpoint mode to insure that you are exactly
centered over the target. Or you may reduce the
sensitivity level and 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
one of the following:
a) Switch to the Autotune mode.
b) Reduce your sensitivity level.
c) Slow down your sweep speed.
d) 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
balance.
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
above.
28
FALSE SIGNALS
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
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

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.

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. Always
replace both batteries at the same time. You may also use
rechargeable Nicads but expect about 1/2 the battery life of
an alkaline battery.
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 not turn on. The instrument
will not be damaged.
4. Finger tighten the screws down snugly. Do not use a
screwdriver or other hand tool.
Figure 9. Battery replacement
31
MAINTENANCE
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 HUNTERS’ 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.
33
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.
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.
