Read this instruction manual thoroughly, practice often and you will be ready for some exciting treasure hunting. Drop us a line if you have any questions, comments or good finds to tell us about. In the meantime... Happy Hunting! Fisher Research Laboratory...
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.

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.
NOTE: 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-3D is the search coil.

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.
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.
“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 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.
“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.
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.

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”...

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.

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.

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-3D operators don’t even bother with the Pinpoint mode unless they want a depth reading.
Page 22
TARGET IDENTIFICATION 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.
Page 23
TARGET IDENTIFICATION 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.
DEPTH READING Your CZ-3D 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.
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 A heavy duty blunt screwdriver, sturdy hunting knife, or garden trowel are commonly used. Made especially for the Hobby of Metal Detecting are several well designed sand scoops, trowels, and digging tools . See your local dealer for more information. FALSE SIGNALS A “False Signal”...
FALSE SIGNALS Figure 8. TARGETS THAT AREN’T THERE. Coin lying at an angle or on edge. Long ferrous object (nail). Large deep target (water pipe). MAINTENANCE Your CZ-3D 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.
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.
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.
