Product Description

This Fisher CZ-21 is ready to get you diving at the beach and finding those sunken treasures. With a diving depth of up to 250ft, you won't have a reason to not dig a little deeper for that find of a lifetime waiting for you in the sand. Designed for saltwater, the CZ-21 also performs great in other mineralized conditions like clay soil. Also included in this bundle are some Kellyco tools to help you recover your finds.

Any warranties purchased through Extend only apply to the metal detector. The included accessories in a bundle are not covered by warranty.

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

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.
