The metal detector circuit shown here must represent the limits of simplicity for a metal detector, yet the design works surprisingly well. It uses just one 40106 hex Schmitt inverter IC, a capacitor and a search coil – and of course the batteries.
For the search coil, I wound ~4m of stranded wire around a cardboard cylinder with 9 cm diameter, resulting in about 18 windings. The type of cable is irrelevant, as long as the ohmic resistance is at least ten times …
Metal Detector is a security device which is used for detecting metals which can be harmful, at various places like Airports, shopping malls, cinemas, etc. Previously we have made a very simple Metal detector without a microcontroller, now we are building the Metal Detector using Arduino.In this project, we are going to use a coil and capacitor …
White's Surfmaster PI is a good quality, fully waterproof, lightweight metal detector with an exceptional depth in saltwater or mineralized ground. It's ideal for those wishing to search beaches, in the surf or shallow diving. It works inland too, but such use is not advised as -- like all PI (Pulse Induction) designs -- there is no effective discrimination of …

A PI metal detector, however, will negate these issues and allow more positive target identification. Keep in mind that many PI metal detectors have a learning curve and are best suited to more intermediate or advanced metal detectorists. Below, you will find my top 10 picks for best PI metal detectors for gold. Garrett ATX
When it comes to metal detectors in general, there are mainly 2 different types VLF (Very Low Frequency) and PI (Pulse Induction) Detectors … However, unless you are a professional Gold Prospector, all what you will need most of the time is a VLF Detector …
Pulse induction metal detectors can deal much more effectively with complex, undulating ground conditions. For this reason, pulse induction devices work …
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.
A typical metal detector used for detecting buried coins, gold, or landmines consists of a circular horizontal coil assembly held just above the ground as shown in the figure to the right. Other uses of more specialized metal detectors include usage in medicine, security etc. Metal detectors have been used for diagnostic purposes since 1881.
UNDERSTANDING THE PI METAL DETECTOR BY REG SNIFF. One of the more popular metal detectors used for nugget hunting today is a type of detector commonly called the Pulse Induction or PI for short.
