ABOUT YOUR DETECTOR Your CZ-3D is an extremely advanced and sophisticated instrument. It is maximized for a very specific function - finding & properly identifying older era coins at older sites. Simply select the "enhance mode" with the utilization of the "salt/ enhance" switch to find more rare coins! The CZ-3D was designed to find more good metals such as brass, bronze, copper, silver, and certain gold: reporting it as a high tone. In addition, a fourth tone has been added to distinguish be

CONDENSED OPERATING INSTRUCTIONS FACTORY PRE-SET “TURN-ON-AND-GO” MARKS Your CZ-3D 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-3D to your specific needs and conditions. A good understanding what to do and why will lead you to more finds. If you can’t wait any longer, and you’re an experienced detector user, here’s some quick instructions to get you going: 1.

SETTING UP 5. With the stem length properly adjusted, wrap the loop cable tightly around the center section 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 illus

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. It is especially important that the cable connector be installed tightly to prevent false sign

CONTROL PANEL or identify targets. 3. PINPOINT/DEPTH READING: A three purpose, spring loaded push-button. When pushed and held, the CZ-3D 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. 4. SENSITIVITY/BATT TEST: In the extreme counter- clockwise position, the battery condition is checked as indicated by a strong or weak

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 =ENHANCE 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 ca

“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 an

"BOBBING" THE SEARCH COIL METHOD 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 c

“BOBBING” THE SEARCH COIL METHOD 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 wi

SEARCH MODES AUTOTUNE SEARCH MODE Set the DISC control to Autotune for 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 li

SEARCH MODES 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 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 n

SEARCH MODES the surface may set off the bell tone. The optional, smaller 5 inch coil is more likely to overload than the standard 8 inch coil. 10. You may also note that some square 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 pieces of tabs or aluminum are often misidentified. The tail of a round tab for example, may ID as a nicke

SEARCHING Good search techniques are as important to your success as having a good detector. 1. Make sure your CZ-3D is properly ground balanced and the MODE switch is in the proper position: SALT for wet ocean beaches, ENHANCE for just about every other situation. 2. Decide which search mode you’re going to use, Target ID or Autotune. 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

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-3D, 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
