• 10" Waterproof Searchcoil for Land and Underwater Detection: The Fisher CZ-21 Quicksilver features a 10" waterproof searchcoil designed for versatile use on land, in shallow water, or underwater up to depths of 250 feet. This larger searchcoil enhances sensitivity and provides broader ground coverage for precise detection of coins, relics, jewelry, and gold in a variety of environments, making it an excellent choice for treasure hunters and divers seeking maximum efficiency.
• Dual-Frequency VLF Technology for Superior Performance: Operating at 5 kHz and 15 kHz simultaneously, the CZ-21 delivers enhanced target detection and analysis. This dual-frequency system provides more information about targets, ensuring accurate identification of valuable metals like gold and silver, while minimizing false signals from iron and mineralized ground.
• Advanced Target-ID System with 3-Tone Audio: The CZ-21 features a sophisticated Target-ID system that uses 3-tone audio responses to identify metal types. Low tones indicate iron, mid-tones signal pull tabs and gold, and high tones denote coins and silver. A unique bell tone alerts users to large, shallow targets, helping pinpoint treasures with ease.
• Auto-Tune and Target-ID Modes for Flexible Searching: This metal detector offers two distinct search modes to suit various conditions. The Auto-Tune mode provides wide-scan, all-metal detection for maximum sensitivity and depth, while the Target-ID mode combines silent operation with precise discrimination to filter out unwanted items like nails and foil.
• Manual Ground Balancing and Saltwater Compensation: With manual ground balancing, the CZ-21 adjusts to mineralized soils and black sand for stable operation. Its advanced saltwater compensation cancels out the conductive signals caused by saltwater, making it perfect for beach and underwater detecting without interference.
• Durable and Comfortable Design for Extended Use: Built with a cushioned armrest, soft foam grip, and a hip-mountable control housing, the CZ-21 is designed for long treasure-hunting sessions. Powered by four 9-volt batteries, it delivers up to 55 hours of operation, ensuring reliability for both professional divers and hobbyists.
