  • Page 3: About Your Detector

    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.
  • Page 4 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.
  • Page 5 ABOUT YOUR DETECTOR 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.

  • Page 6: Condensed Operating Instructions

    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.

  • Page 7: Setting Up

    Upper stem Figure 1. Fisher M-Scope CZ-5 Quicksilver Built-in detector stand 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.
  • Page 8 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.

  • Page 9: Hipmounting

    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.
  • Page 10 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.

  • Page 11: Turn-On Procedure

    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.

  • Page 12: Pushbutton Method

    “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.

  • Page 13: Bobbing" The Search Coil Method

    “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.

  • Page 14: Search Modes

    “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.

  • Page 15: Target Id

    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.
  • Page 16 SEARCH MODES 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.
  • Page 17 SEARCH MODES 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.
  • Page 18 SEARCH MODES 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.

  • Page 19: Searching

    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.
  • Page 20 SEARCHING Figure 5. Search pattern. 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. 9.
  • Page 21 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.

  • Page 23: Target Id And Autotune Modes

    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.
  • Page 24 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 25 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.

  • Page 26: Depth Reading

    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.

  • Page 27: Target Recovery

    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.

  • Page 28: Recovery Tools

    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.
  • Page 29 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.
  • Page 30 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.
  • Page 31 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.
  • Page 32 FALSE SIGNALS problem, try one or more of the following: a) Keep your sweep smooth, slow and low to the ground b) Check your ground balance c) Lower your sensitivity d) Make sure your search coil is properly secured and the cable connector is firmly tightened. 9.

  • Page 33: Battery Replacement

    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.

  • Page 34: Maintenance

    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.
