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 nickel. However, most tabs and most of the items on the CZ-3D meter face will be identified correctly.

11.Now increase the DISC control to “1”. You will find that the CZ-3Drejectsthesmallirontargetsandnolongerresponds 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. At DISC = 4 for example, you are in a “coins-only” mode, ignoring iron, tabs and foil while accepting and identifying most nickels, zinc pennies and silver, clad and copper coins.

13.At the maximum DISC level of 6 the CZ-3D will ignore most all-small targets except silver, clad, zinc and copper coins.

14.Now switch the DISC control to the AUTOTUNE position and note the completely different kind of response. No tone or meter identification, just a solid, smooth, response over every target.

15.The chart on page 14 shows some of the responses you may expect over different targets and at different levels of discrimination. As you progressively increase the discrimination level, you eliminate more and more targets.

NOTE: Due to the virtually infinite variety of sizes, shapes and alloys of many “good” targets (relics, jewelry, foreign coins, etc.), they may be misidentified. For example, a Civil War mini ball may be identified as foil, or a new Canadian coin as a rectangular pull tab.

CZ-3D specifications

The Fisher CZ-3D is a highly respected metal detector renowned for its sensitivity and versatility, particularly among treasure hunters and coin collectors. Fisher Laboratories, with a rich history in the metal detection industry, developed the CZ-3D to cater to more experienced users who seek depth, precision, and advanced features in their detecting devices.

One of the main features of the CZ-3D is its ability to detect both ferrous and non-ferrous metals with exceptional accuracy. This dual function allows users to identify a wider variety of targets, from coins and jewelry to relics and artifacts. The CZ-3D is specifically tuned to recognize the nuanced differences among targets, which significantly improves the detectorist's chances of locating valuable finds while ignoring unwanted trash.

The CZ-3D employs an advanced discrimination system that expertly filters out undesirable metals. This is particularly valuable when hunting in trashy areas where targets can be closely situated. The device features a unique “3D” mode, which aids in evaluating targets before they are unearthed. This mode also allows user to experience a more intuitive understanding of the ground conditions and target depths, enhancing overall efficiency.

Another notable characteristic of the CZ-3D is its exceptional depth performance. It utilizes a dual-frequency technology, operating at both 5 kHz and 15 kHz. This capability enables the detector to achieve greater penetration into the ground, providing the ability to locate deeper targets that many other detectors might miss. This is especially useful in areas with high mineralization where standard detectors may struggle.

Ergonomics also play a crucial role in the design of the CZ-3D. The device features a lightweight construction that ensures comfortable usage over extended periods. The adjustable shaft and user-friendly control layout allow for easy customization to suit individual preferences. Users can conveniently access settings such as sensitivity and discrimination levels, enhancing the overall user experience.

Water-resistant components make the CZ-3D suitable for various hunting environments, allowing operations in wet or humid conditions. This versatility broadens the scope of potential searching locations, from beaches and parks to rivers and fields.

In summary, the Fisher CZ-3D is distinguished by its powerful detection capabilities, advanced discrimination features, dual-frequency technology, and ergonomic design. For serious treasure hunters and coin collectors, the CZ-3D represents a dependable tool that combines innovation with practicality, making it a preferred choice for those aiming to uncover hidden treasures beneath the earth.
