A microprocessor-controlled Pulse Induction detector design.
A highlight of the work is its inclusion of working example designs and experiments, allowing readers to build their own equipment: . GEB-discriminators . Microprocessor-controlled PI detectors . Editions and Availability
Covers VLF (Very Low Frequency) ground balance, motion filtering, and pulse induction timing. 🏗️ Major Detector Topologies A microprocessor-controlled Pulse Induction detector design
The book explains the basics of induction , magnetics , and eddy currents , including how targets respond to magnetic fields.
The only minor drawback is the inevitable aging of the technology. The book focuses heavily on analog circuits. While the physics of induction remain the same, modern detectors are increasingly digital, utilizing DSP (Digital Signal Processing) and complex software algorithms. The book touches on this, but the core content is analog hardware design. Microprocessor-controlled PI detectors
: A 230-page or 250-page guide that covers the basics and core categories like BFO and PI.
“Inside the Metal Detector” by George Overton and Carl Moreland is the definitive for understanding VLF induction balance metal detectors from coil to audio output. If you want to move beyond “turn on and dig” into actual circuit operation, phase discrimination, and ground balancing, this PDF is essential reading. The only minor drawback is the inevitable aging
