This offers the advantage that it can precisely locate both large, deep-lying objects and small, surface-level metal pieces. Thanks to the dual-frequency technology and Fourier-domain analysis, the CZ21 detects various types of metal with high accuracy and indicates them via a clear 3-tone audio signal. For example, iron is signaled by a low tone, while valuable metals such as silver and gold are signaled by higher tones.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eHow user-friendly is the Fisher CZ21 underwater detector, and is it easy to distinguish unwanted metal?\u003c\/h3\u003e\n\u003cp\u003eThe CZ21 is equipped with an adjustable discrimination function, which allows you to filter out unwanted objects such as nails or other iron objects. The operating concept of the metal detector is designed to be extremely user-friendly. With only four rotary knobs and one push button, the detector is quick and easy to set up. This makes it suitable for both beginners and professional treasure hunters looking for lost treasures or valuable finds in difficult environments.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat advantages does the 25 cm concentric search coil of the Fisher CZ21 offer in combination with the pinpoint function?\u003c\/h3\u003e\n\u003cp\u003eThe Fisher CZ21 search device is equipped with a robust and waterproof concentric 25 cm search coil.
