Metal detectors are categorized into four groups based on their operating principles, beat-frequency, oscillation, and resonant frequency oscillation.
These are the two early techniques used in metal detectors.
Detectors based on these principles are not preferred due to frequency stability issues. Induction balance (IB) and pulse induction (PI) detectors are more widely used.
Pulse Induction (PI) is a type of metal detecting technology. A pulse induction metal detector operates by sending short pulses of voltage to the metal detector coil. These short pulses cause a magnetic field to be generated, which quickly dissipates at each pulse’s end.
Any metal targets that induce the magnetic field remain magnetized for a short time after the end of a pulse. The detector’s coil then detects the target’s decaying magnetism.
A pulse induction metal detector can deal more effectively with much more complex, variable ground conditions; this is the reason a pulse induction metal detector works so well for gold detecting, and pulse induction machines are excellent for working the beach and searching for gold nuggets.

What is the best pulse induction metal detector?
On the market are several Pulse Induction machines, and we want to recommend the best ones for 2021.
Minelab GPX 500 is some of the best technology you can have in a pulse induction metal detector. If you’re looking for gold nuggets or any other metal, this device is perfect for you. Plus, we have a special bundle, and this metal detector comes with two coils and several accessories.
This is the best example of what a multi-frequency pulse induction metal detector should be—certified for all-terrain (AT) deserts, mountains, in any (X) Xtreme conditions such as saltwater beaches (waterproof up to 10 feet – 3 meters) and any highly mineralized terrain.
GARRETT Sea Hunter Mark II the best for underwater treasure hunting!
If you want a submersible Pulse Induction metal detector that discriminates, look no further than the Sea Hunter Mark II. Besides providing standard discrimination, the Sea Hunter Mark II has an exclusive Discrete Elimination mode that allows it to discriminate, unlike any other manufactured IP.
With Klarna, you can get it by as low as $107/month.
