I have designed the metal detector works on the principle of beating is generated due to the difference of the oscillation model and tunable oscillators (5-10-th harmonic, selects the nearest frequency). This allows to increase the sensitivity of the instrument to the point that it becomes possible to detect, say, a five-kopeck coin in the soil at 10 cm, and a steel manhole or pipe — to 65-cm depth. Performed on the available element base, a metal detector does not require careful tuning and maintenance. Power supply — galvanic battery “Crown”.
