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.
ABOUT YOUR DETECTOR • • • • • • • • or the medium tone of pull-tabs 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.

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. And if you have a good understanding of how to do it and why, you’ll find more.

SETTING UP 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 a- round the upper stem and secure it with the two Velcro straps. Connect the cable connector to the control housing.
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.
CONTROL PANEL 3. PINPOINT/DEPTH READING: A three purpose, spring loaded push-button. When pushed and held, the CZ-5 goes into a nomotion, all-metal mode for precise pinpointing and approximate depth reading of coin-sized targets. This button is also used in conjunction with the GROUND control during the ground balancing procedure. 4. SENSITIVITY/BATT TEST: In the extreme counterclockwise position, the battery condition is checked as indicated by a strong or weak tone and a meter reading.
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).
“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.
“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.
“BOBBING” THE SEARCH COIL METHOD 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 counter-clockwise) in small increments until there is little or no change in the threshold level. 7.
SEARCH MODES you’re in a very sensitive, wide-scan, all-metal, motion search mode. Since this mode 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 MODES 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 steeltargets, the meter needle will usually lock in the “IRON’ category.
SEARCH MODES 9. When you go over a large, shallow target the CZ-5 will respond with a distinctive bell tone. 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 CZ5, 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.
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.
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 1.D. or Auto tune. Recommended starting point: Target ID mode with the DISC control set at 4. 3. Set your SENSITIVITY control.
SEARCHING When the stem length is properly adjusted, the CZ-5 is balanced for sweeping in a tight semicircle. Wide to the right for right handers. Wide to the left for left handers. Be sure to overlap your sweeps. Figure 6. Search pattern. 8. Search in a methodical manner. Pay close attention to where you’re going and where you’ve been. 9. Keep the search coil moving at a comfortable rate.

Discrimination set at “5.” 3. Maximum Depth a. Moderate sweep speed. b. Discrimination set at “0.” 4. Missed Target Many targets within the range of your 1225-X will not be detected unless you closely overlap your swings.
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, Auto tune or Target ID.) 2.
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.
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.
TARGET IDENTIFICATION 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. 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.
DEPTH READING any size target, depth reading is only accurate for coin size targets. 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.
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: 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.
FALSE SIGNALS 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.
FALSE SIGNALS 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 bell tone response or constant false signals.
FALSE SIGNALS 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.
FALSE SIGNALS 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.
OPERATING TIPS 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.
OPERATING TIPS 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 Auto tune 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.
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.
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.
