Explore the depths with the CZ-21 QuickSilver Premium Multi-Frequency Underwater Metal Detector, a versatile tool designed for both land and underwater treasure hunting. This high-performance metal detector is submersible up to 250 feet, making it an ideal choice for beach, salt, and freshwater explorations.
The CZ-21 QuickSilver is equipped with an 8" searchcoil and operates on dual VLF signals at 5KHz and 15KHz frequencies. These frequencies provide twice the target information, ensuring accurate analysis and identification of your finds. Its patented Fourier domain signal analysis further enhances depth detection, allowing you to uncover hidden treasures buried deep below the surface.
This underwater metal detector features a 3-Tone Target-ID system, offering a low tone for iron, a mid-tone for pull tabs, foil, and most gold rings, and a high tone for U.S. coins, silver rings, and certain gold rings. This system simplifies your search by categorizing detected metals based on their tones.
The CZ-21 QuickSilver offers two search modes: a silent, slow-motion Target-ID Mode and a dynamic Auto-Tune Mode for All Metal searching. Its V.C.O. No-Motion Pinpointing feature increases the audio tone's pitch and volume as the coil approaches the target, ensuring precise detection.
The device also features a Big-Target Alert that warns you of large, shallow targets that may overload the circuits. Its Faint-Target Audio Boost increases the volume of deep, faint target sounds, enhancing your detection capabilities.
The CZ-21 QuickSilver is designed for ease of use and comfort. It features a cushioned armrest, a soft foam grip, and a control housing that can be detached from the handle and mounted on your belt. The device also includes a separately sealed battery compartment for added protection against accidental flooding.
This metal detector also boasts a Salt Water Compensation feature, using Fourier Domain signal analysis to cancel out false signals from electrically conductive salt water. This ensures a smooth and uninterrupted search, even in the surf zone at high sensitivity settings.
Whether you're a seasoned treasure hunter or a beginner, the CZ-21 QuickSilver Premium Multi-Frequency Underwater Metal Detector offers a user-friendly experience. Simply set the control on the red circles for a "coins-only" mode, or adjust the controls to suit your specific situation and start your treasure hunting adventure.
