Description
The Fisher CZ-21 is a professional-grade metal detector designed for serious treasure hunters who explore land, beaches, and underwater environments. Built to withstand depths of up to 250 feet, it’s perfect for divers, beachcombers, and anyone searching in wet or mineralized conditions. What sets it apart is its dual-frequency VLF technology, providing advanced target analysis in both salt and freshwater.
The CZ-21 uses simultaneous 5 kHz and 15 kHz frequencies to deliver deep, accurate target detection across a range of soil and water conditions. Its 3-tone audio Target-ID system helps you distinguish between iron, foil, and coins or jewelry without even looking at the control panel. The unit features a silent-search discrimination mode, Auto-Tune for all-metal searching, and a V.C.O. pinpoint mode for precision target recovery. With features like manual ground balance, audio boost for faint targets, and saltwater compensation, it adapts to even the toughest environments.
Designed for extreme conditions, the CZ-21 is housed in a waterproof shell and includes permanently attached waterproof headphones. Its durable fiberglass construction, hip-mountable control box, and adjustable armrest make long hunts comfortable and manageable. Powered by four 9V batteries, it offers up to 55 hours of operation, ensuring you stay in the field longer without interruptions. Whether on the beach or beneath the waves, the CZ-21 is engineered for performance and built to last.
Purpose: Deep Diving, Relic Hunting, Coin Shooting, Beach Hunting, Jewelry
