Fisher Metal Detectors

The Fisher CZ 21 metal detector

The Fisher CZ 21 metal detector is suited for treasure hunters who want to go underwater. The CZ 21 metal detector can be used out of the water, at the beach or at the countryside. It is designed for experienced explorers. The device can be easily disassembles and stored in a small space when not used. A search can last up to 45 hours.

This device is fairly easy to use with its four rotary switches. The rotary switches are used for adjusting the volume, the metal distinction level (the hide of certain metals), the soil balance (allowing a search in heavily mineralized soils) and the search performance (sensitivity, including the battery test). CZ 21 can easily be used at a depth of 75 m in both salt and freshwater. A 3-tone acoustic display is used for rough object recognition.

Additionally, the hand held metal detectors have a visual LED display. The Fisher CZ 21 metal detector contains another pinpoint (no motion) for the identification of the precise location. It uses a dual frequency (5 & 15 kHz) and is equipped with a 20 cm search coil.

Those who want to buy this underwater metal detector also get additional accessories (a search coil, pockets and so on). The offer varies from one provider to another.

The Fisher CZ-3D metal detector

Fisher CZ-3D is a very user-friendly metal detector ideal for searching for coins, relics and military items. The CZ-3D model can be used on the beach or in saltwater. With its three-part case, the metal detector is quickly assembled and ready for use. It weighs about 1700 grams, so you can hold it in your hand, so that longer tours should not be a problem.
It features an optical needle display (e.g. distinguishes between iron, cooker plates, coins and foil) and has 4 tones for the metal distinction. Seven different metals can be distinguished. It also features an all metals mode. A controller is used for adjusting both the sensitivity and the search depth (penetration depth). A manual soil examination can be carried out at any time if there are any problems. There is an extra controller for the ground mineralization examination. This increased search depth is provided for heavily mineralized and saline soils. Of course, the objects can be located precisely with the help of the pinpoint. The volume can also be adjusted accordingly. The search properties can be improved using an extra button if the treasure hunt takes place in saltwater. The device has two different frequencies. A search can last 20-30 hours if the batteries are charged.

The Fisher CZ 3D Fisher metal detectors are equipped with a waterproof spider coil of 20 cm, which can be expanded by further coils. There are also other accessories such as bags, depending on the demand. You should ask for a manual when purchasing such a device so that you can find all the functions and have fun on the search.
