Fisher CZ-21 Metal Detector

If it's in the Ground or in the Water a Fisher Metal Detector Will Find it!

CZ21 Face

You can go anywhere with the CZ-21 even 250 feet underwater. The CZ-21 is a go-anywhere, do anything, all-weather, target-ID machine that is leak proof to 250 feet. And its patented electronics make it deep-seeking while it ignores the destabilizing effects of salt water. It is the perfect target ID 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.

Target ID: put on the headphones, swing the search coil, and listen to the 3-tone Target ID A low tone means you are 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 are over big, shallow targets, no more digging beer cans! For precise pinpointing, use the Pinpoint button, which puts the detector in a no-motion-required, all metal mode. See for yourself: If you are an all-around treasure hunter who will not settle for second best, the CZ-21 is the detector for you.

Summary of Field Test (Reprinted from Lost Treasure Magazine): Incorporating all of the features of the field-proven CZ-5 and CZ-6 with the exception of the meter, the CZ-21 should prove to be an extremely popular detector with not only water and beach hunters, but coin and relic hunters who want a top-notch detector that is totally impervious to the elements. This is truly a detector that will perform equally as well in salt-water surf as it will in a fresh water lake, a school yard, or mineralized battlefield or campsite.

The CZ-21 comes with Fisher's two year warranty, which considering it's an underwater detector, shows how confident the factory is that it will hold up under virtually any condition one might use it in. *Due to the special sealing and waterproofing of the Fisher CZ-21 underwater detectors the factory requires any unit needing warranty service or replacement to be sent directly to the factory and not the dealer where purchased from. Please refer to your supplied warranty information from the factory.

    Review by Pirate on May 29, 2022

    I have used my 2nd CZ 21 for many years. I have used other brands of underwear detector's. Fisher by far make the most rugged. Dependable, ease of use. Durable. Underwater Detector made. There is a reason why they didn't change the design over the years. No need to. The batteries are located in a separate sealed compartment. So failure is not going to happen. My use of the Fisher CZ has allowed me to find over 15 lbs of Silver Coins, hundreds of gold rings , and over 21 lbs of Silver Jewelry. I even have found gold nuggets in California Rivers.
    It works very well. I find it unmatched. I recommend Kellyco for the Fisher CZ 21 or 1280X.
