Electronic metal detectors belong to products that have always aroused the interest of a wide group of hobbyists. The easiest way to determine if there is a metal object in the vicinity of the coil (probe of the detector) is to accurately measure the frequency generated by the generator. This solution was used in the AVT5025 kit . Thanks to the use of a microprocessor and an appropriate work algorithm, it was possible to eliminate such inconveniences as generator instability, difficulty in noticing a small deviation at the time of locating the metal, etc. In the system, the frequency of the Collpitsa generator determines the external coil-probe. The system works at approx. 32 kHz. The signal is amplified and directed to the microprocessor input, in which its further, comprehensive processing takes place. The detection of the 'treasure' is signaled visually and acoustically. The system is uncomplicated in assembly and easy to start.
The device is especially recommended for seekers of military and various other treasures buried in the ground
