Fisher CZ-3D Metal Detector

Description

The FISHER CZ-3D detector will give a fast and accurate reading of objects up to the size of a coin. It is an extremely advanced and sophisticated instrument in terms of features although very easy to use. To visually identify the objects on the screen there is a very easy meter to interpret, it shows seven categories of small objects. When the dual frequency circuit identifies an object, the needle will mark in the appropriate category. This model acoustically identifies whether the meter indicates iron, tin rings, aluminum foil, or coins whether you are searching on the beach or searching on normal land. As long as the tone is high, it will be a good object. Salt water is not a problem for the CZ-3D, you can submerge the plate and detect as if it were not; you just have to move the switch and readjust the balance with the ground. The control box is semi-waterproofed. This instrument, in addition to separating nickels from scrap metal, also carries a category of rectangular rings, one of the round ones, nickel and aluminum foil. The individual categories are arranged in sequence to ensure maximum recovery of good objects and allows us to reject objects that do not interest us. Due to the "Fourier Domain Signal Analysis" system, it can detect deep objects in mineralized earth through the transmission of two signals that give the circuit compensated responses to analyze, compare and identify. The discrimination control can be adjusted in one of its seven categories and in this way, the circuit will ignore everything below the discrimination category that we have adjusted.
