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.
Spirit PI wireless metal detector based Arduino Spirit pi wireless metal detector based Arduino is an impulse metal detector. This metal detector is based on an Arduino or esp32 micro-controller and a smartphone. this metal detector is easier to assemble although it contains more parts than vlf detectors like “smart hunter” because we don’t need to adjust the …
The used app is designed to connect simple metal detector circuits to the iPhone via the headphone jack. This homemade metal detector circuits are very simple and can be made by anyone who has never held a soldering iron in their hands. Metal detectors can detect and discriminate between ferrous and non-ferrous (particularly gold and silver) …
A redesigned version of the well-known impulse metal detector – “Pirate”, but on Arduino. Has good sensitivity even for small coins. Stable regardless of temperature and battery charge. The scheme of Pulse Metal Detector based Arduino is simplified as much as possible. Among the shortcomings, one can note the lack of the ability to determine the type of …
Pi polonaise metal detector one of detectors which have a number of advantages over detectors working on a different principle. They include a large range, practically the same in the air and in the ground, very good sensitivity and complete insensitivity to changes in soil mineralization. The disadvantage is that it is not possible to …
Simple and reliable metal detector If you have lost the ring, key, screwdriver … and you know the approximate place of loss, then do not despair! You can assemble a Simple metal detector with your own hands or ask a radio amateur friend to assemble it. Below is a diagram of an easy diy and …
GOLDEN MASK 4 pro Welcome, dear readers , here we always try to collect more metal detectors that can be assembled at home, and publish useful information for metal detectors and exchange useful things. I found a new and good review to make a new modification of the metal detector called the Golden Mask Pro …
Pulsed metal detector White SurfPI Pro, which is used for underwater search by professional. Fully sealed to a depth of 30 m. Successfully working in sea water and on highly mineralized soil. Metal detector White Surfpi is also well suited for ground search in wet sand. It has a custom sound threshold to achieve the …
After a few months of research for the problems of discrimination and “Coil Error” in the Felezjoo PI, I finally find a temporary solution that can make the device more useful. this problem is often encountered when the components used do not match the detailed description given by the developer of FelezJoo. Since the source …
“Hammerhead” is a pulse induction (PI) metal detector design. It is intended primarily as a learning platform for experimenters, and as a base design on which to expand. This design is very much like other commercial PI detectors, which tend to have similar circuit designs, so it has the potential for good performance.This project includes …
