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.

Assembling the metal detector Clone PI W do it yourself Assembling the metal detector, you should start by selecting the option of the printed circuit board. Since they have small differences in the components used. We recommend choosing a version from DexAlex , its breeding option for this and other metal detectors, we have proven …
To assemble Clone Pi W we need the following details : Microcontroller Atmega8-16PU (8A-16) – 1 pc chips CD4066 – 1pc TL074 or TL084 – 1pc Transistors IRF740 or IRF630 or IRF840 – 1 piece 2N5551 or S9014 – 4pcs 2N7000 – 1 pc Linear voltage 78L05 – 1 pc Adjustable zener TL431 – 1 …
There are three best and repeatedly proven schemes that differ only in key chips: ● scheme with ADG444 ● circuit with КР590КН2 (differs from the first only in a printed circuit board); ● circuit from CD4066 (4016). These schemes are 100% working, so no complaints about their inoperability are not accepted. If you have not …
