Pulse Induction (PI) metal detectors use a method called pulse induction to detect metals. They operate by sending short, powerful bursts of electrical current through a coil, creating a magnetic pulse. When this pulse interacts with metal objects, it induces a secondary magnetic field that the detector’s receiver coil picks up. The system measures the time it takes for the magnetic pulse to dissipate, which varies depending on the type and size of the metal. PI detectors are highly effective in highly mineralized soils and are often used in deep-sea diving, treasure hunting, and detecting metal in challenging environments.
Delta Pulse – Bulgarian Pulse Depth Detector The device operates by amplifying and registering weak signals after a powerful probing pulse, using two strobe signals instead of one. This method helps reduce the influence of the ground, which is particularly challenging in Bulgaria due to heavy soil conditions. The “Delta Pulse” is a pulse induction …
Modified version of the Clone PI-W The 14th version of the circuit board turned out to be quite successful. Today, the commercial attractiveness of the device has significantly decreased – even an increase in the price of scrap metal does not lead to demand for this device among traders. I hardly see metal hunters in …
Metal Detector PIRAT MTX The PIRAT MTX metal detector has ended up in need of repair. I quickly sketched out its circuit, PIRAT MTX, and took a couple of photos inside the electronic block. In case someone has to repair such a metal detector, as quite a few of them have been produced. The Detector …
Improved Pulse Metal Detector Like metal detectors of other types, Pulse Induction (PI) metal detectors are continuously being improved. The application of new circuitry solutions has led to even higher sensitivity in these devices. For example, sensitivity of the metal object detector described in the previous section can be enhanced. In the author’s opinion, the …
Simple Metal Detector (Pinpointer) Among the advantages of the device, we can mention very low power consumption (5 mA from a “Krona” battery), ease of adjustment, and the absence of problems with any interference. simple metal pinpointer detector . Device scheme: Its sensitive element is the oscillatory circuit of the generator, assembled according to the …
Without a doubt, I can say that this is the simplest metal detector of all that I have seen. It is based on just one TDA0161 microchip. You won’t need to program anything – just assemble it, and that’s it. Another significant difference is that it doesn’t make any sounds during operation, unlike a metal …

Metal detector AQUASOUND The AQUASOUND metal detector is a device that selects metals and has the ability to phase-cut the earth (and salty sea water). The scheme of the device is taken from the Internet (possibly old and with errors). This metal detector is quite popular in America and Florida in particular. There are many videos on YouTube on the topic …
