The Fisher CZ-21 Quicksilver metal detector is a top-of-the line detector for the versatile hunter to use anywhere. Completely waterproof, the CZ-21 is all-terrain and all-weather. Dive down to 250 meters in salt or freshwater; use it in shallow water or on land with the same outstanding results.
With an easy manual ground balance, one-touch pinpointing, autotune and a 3-tone audio target ID, the CZ-21 is simple enough for the beginning treasure hunter but delivers performance for the pro.
