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 every situation but you’ll probably want to run it as high as you can. Recommended starting point: SENSITIVITY 5 . If you’re in the Autotune mode, set it so that you can just barely hear a slight audio hum.

4.Adjust your VOLUME control. Remember that a setting above 5 will amplify the response of faint targets so they sound like a shallow or large target. Some searchers prefer not to use it above 5 so the audio response will give them some idea as to the depth and/or size of the target. Recommended starting point: VOLUME = 10. If you’re using headphones, adjust the headphone volume controls for a comfortable, not-too-loud response over loud targets.

5.Once you’ve got your controls properly set, begin your search by walking slowly and sweeping the search coil in a tight semicircle.

6.Keep the coil parallel to the ground and as close to the ground as practical. This is extremely important for maximum coverage and depth. If you’re searching on a lawn, you may set the coil right on the grass and slightly “scrub” it.

7.Overlap your sweeps by at least 50%. Remember that your coil’s search pattern is conical and if you don’t overlap each sweep you’ll miss the deeper targets.

8.Search in a methodical manner. Pay close attention to where you’re going and where you’ve been.

9.Keep the search coil moving at a comfortable rate. Remember that the CZ-3D is a motion detector and responds only when the coil (or the target) is moving (except in the Pinpoint mode).

10. Take your time. If you walk too fast you can’t overlap your sweeps and you’ll miss a lot of ground. If you swing your coil too fast you lose some sensitivity to deep and/or small targets.

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.
