A Pulse Induction (PI) metal detector is a type of metal detector that uses short, powerful pulses of electromagnetic energy to detect buried metal objects. Unlike other types of metal detectors, PI detectors are known for their ability to penetrate deeply into highly mineralized or conductive soils, making them ideal for gold prospecting and searching in challenging environments.
Here's a more detailed explanation:
How it works:
Pulsed Electromagnetic Field:
PI detectors send out short, high-energy pulses of current through a coil of wire. These pulses create a magnetic field.
Magnetic Field Collapse:
When the pulse is turned off, the magnetic field collapses rapidly.
Target Response:
If a metal object is nearby, the collapsing magnetic field induces an electrical current in the target. This current then creates its own magnetic field, which the detector senses as a return signal.
Decay Time Measurement:
PI detectors don't just detect the presence of a signal;
