The Fisher CZ 21 Quick Silver is certainly one of the best underwater detectors currently available. With a possible diving depth of up to 80 metres, it can be used almost indefinitely. The detector locates simultaneously at 2 different operating frequencies of 5 and 15 kHz. The result is deep detection with very good sensitivity to small parts. In places where it is not possible to swivel for space reasons, it is easy to search in all-metal mode.
The CZ21 shows its strengths on the beach, not least due to its robust design. The 27cm search coil of this version offers slightly more area coverage and depth gain compared to the 20cm standard coil and naturally makes the detector somewhat more unwieldy under water.
The photo above shows the CZ21 with the 20cm coil. However, the 27cm coil is included with this CZ21-10!
The operation is simple and logical and offers flexible options for discrimination: a) 3-tone discrimination b) with iron filter c) with stepless non-ferrous metal discrimination.
