Fisher CZ-21 QUIKLSILVER Underwater Metal Detector (Fisher-CZ-21)
High-Performance, Submersible, Target-ID Metal Detector
CZ-20 QuickSilver:You can go anywhere, even 250 feet underwater. The CZ-20 is a go-anywhere, do-anything, allweather, target-I.D. machine that's leakproof to 250 feet. And its Patented electronics make it deep-seeking while it ignores the destabilizing effects of saltwater. It's the perfect target-I.D. machine for the versatile treasure hunter who wants to hunt anywhere-underwater, on the beach, in the surf, on dry land and in all kinds of weather.
3-Tone Audio Target I.D: Put on the headphones, swing the search coil, and listen to the 3-tone target-I.D. A low tone means you're over iron, a mid tone means pull tab or gold ring and a high tone means a coin. And a distinctive bell tone lets you know when you're over big, shallow targets. No more digging beer cans!
Twin LED's: Two bright-red, light-emitting diodes flash when you pass over a target and dim as you move away. For precise pinpointing, use the Pinpoint button, which puts the detector in a no-motion-required, all-metal mode.
