Instead of a continuous wave, PI technology sends powerful, short bursts (pulses) of current through a single coil, generating a magnetic field. When the pulse ends, the magnetic field collapses, creating a brief spike in voltage. If the coil is over metal, the target's eddy currents prolong the decay of this magnetic field. PI systems are incredibly powerful and are the go-to choice for saltwater beaches and deep relic hunting, as they are largely unaffected by highly mineralized soil. Hands-On Experiments and DIY Projects

The PDF guide, "Inside The Metal Detector George Overton Carl Moreland.pdf", provides an in-depth look at the work of these two innovators. The guide is a comprehensive resource that details the design, development, and testing of various metal detectors. It includes technical specifications, schematics, and photographs of the detectors, as well as insights into the problem-solving process that Overton and Moreland employed.

For hobbyists looking to get their hands dirty, Inside the Metal Detector includes complete, tested projects:

At the heart of every functional metal detector is the physical interaction between electromagnetic fields and conductive materials, a phenomenon fundamentally governed by and Eddy Currents .
