This metal detector has won the fame of a simple and not expensive device, a small number of available parts, with proper assembly and correct parts of the device works immediately, almost without settings.
The transmitting knot consists of the generator of impulses on a chip of KR 1006 VI1 (foreign analogue NE555) and a powerful key on a field transistor of KP 505 a (foreign analogue irf740, irf840). It is possible to put the bipolar transistor of reverse conductivity with a voltage to-e not less than 200. It can be taken from a power-saving lamp or charger from a mobile phone. To pump a powerful key used transistor sun 557.
