Among the huge variety of modern technology The Honorable place is occupied by the metal detector - the device detects hidden metal objects. The scope of such a device is quite wide, it is both security structures, and construction organizations, and amateur archaeology. Wherever you need to find anything underground, in the walls or any hidden objects will come in handy metal detector, and for treasure is a device № 1, without which the search for treasures is almost impossible.

The principle of detector is to capture the magnetic field of the target in the search coil and to transmit this signal to the control unit, then the processor processes the received signal and transmits the information to the monitor screen and in the form of a sound signal. In the absence of a monitor, which is peculiar to analogue and underwater devices, the metal detector informs about the finding only by means of an audio signal, which can be 2-tone, polyphonic of 3-8 tones or multitone, having many options Alarm. For a more accurate capture of the tone of the sound signal, you can use headphones, which may also differ in their capabilities and characteristics. Visually, the metal detector displays data about the find in the form of a digital or analogue scale, or as a graphic picture, which is inherent in more expensive professional models.
