CZ-5 Quicksilver Deep Search, Target I.D. Metal Detector with dual Fourier Domain Signal Analysis Operating Manual F I S H E R R E S E A R C H L A B O R A T O R Y...
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 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.

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.
Seven foot search coil cable Upper stem Figure 1. Fisher M-Scope Built-in detector stand CZ-5 Quicksilver 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.

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.
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.

CONTROL PANEL 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 coin- sized targets. This button is also used in conjunction with the GROUND control during the ground balancing procedure.
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...
“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.
“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.
“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 counterclockwise) in small increments until there is little or no change in the threshold level.
SEARCH MODES 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.

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.

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”...

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.
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.

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. 9.

SEARCHING 1. Minimum Depth a. Very slow or fast sweep speed. b. Discrimination set at “10.” 2. Good Depth a. Moderate sweep speed. b. Discrimination set at “5.” 3. Maximum Depth a. Moderate sweep speed. b. Discrimination set at “0.” 4.
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”...
PINPOINTING 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...
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.
TARGET IDENTIFICATION 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.
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”...

FALSE SIGNALS 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.
Page 29
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.
Page 30
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.
FALSE SIGNALS to your original direction, you’ll receive a single beep directly over the target. 11. OTHER TARGETS THAT AREN’T THERE: Good lock- on, 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.
Page 32
OPERATING TIPS 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”...
Page 33
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 Autotune mode and then identify your targets by switching to DISC = 0.
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.
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.
