In this article we will talk about one of the simple detectors, the assembly of which can be carried. These include transistors with CT and MP marking, as well as resistors and capacitors from popular radio equipment. Most of the necessary parts without problems can be found in old devices.
This device resembles a metal detector on two transistors, but it added a sound amplifier, and, despite the simplicity, it has a good performance of metal detection. It is ideal for mass search and collection of black metal. If you find the details and a little time, you will easily collect the metal detector on the example of this cognitive article.

The diagram assembly can be carried out on a one-sided PCB. Guided by Figure 2, which depicts the circuit detector on transistors, we consider the number of connections and sharp object create the appropriate number of contact areas.
