Schematic diagram of White's Surfmaster PI metal detector - a good quality, simple PI (Pulse Induction) design with an affordable price. Detects all metallic objects with unbelievable depth and sensitivity, on the hardest-to-hunt black sand beaches and in wet salt.
"Spirit PI" is a pulse inductions metal detector. This metal detector is based on an Arduino or ESP32 microcontroller and a smartphone. It is easier to make than a VLF metal detector because you do not need to adjust the coils and adjust the balance of the coils. In this metal detector we only use one coil that at the same time is the ...

Example PI circuit: White's Surfmaster PI schematic diagram The Beat-frequency oscillator (BFO) is the simplest (and oldest) type of metal detector technology and is a good starting point for learning how metal detectors work. The basic beat-frequency metal detector employs two radio frequency oscillators which are tuned near the same frequency.
Here is the web site with the plans and design to build your own metal detector. There are both PI (Pulse Induction) and VLF (Induction balance) detectors described here: Metal Detector Design Schematics. I'd ignore the historic type detectors such as the BFO type units.

Simple Metal Detector: The other day when I was searching instructables I come across on interesting and simple circuit for metal detector. It is build with 555, coil and few other components. Instructable that inspire me to do this project was this one.
May 14, 2015· You can find a metal detector at airports, theaters and various other public places. They are used for the safety of people to detect anyone carrying a metal (Arms etc). In this project we are going to design a simple metal detector circuit. There are so many metal detector designs but most of them are complex in design so here we are going to design a simple metal detector circuit using 555 ...
Pulsed metal detector "VINTIK-PI" based on three ICs and four transistors, designed to search for small metal objects at great depths. The circuit does not contain any programmable micro-controller, and many parts are interchangeable.
