Pulse Induction Metal Detectors

Pulse induction (PI) detectors are built for the ground that defeats ordinary machines: hot mineralized soil, black sand and salt water. They send short, powerful pulses and listen to the echo, which lets them ignore much of the ground's own signal. If depth in difficult ground matters most, start here. Not sure?

Where pulse induction wins

  • Mineralized gold country: a PI stays quiet where a VLF chatters.
  • Wet salt sand and surf: salt has far less effect on PI machines.
  • Depth on larger targets: PI often reaches deeper on bigger nuggets and objects in difficult ground.

The trade-offs

Most PI detectors offer little or no discrimination, so you dig every signal, nails and foil included. Many are heavier and cost more than VLF machines, and they can be less sensitive to the very smallest gold. For small gold in moderate ground, a high-frequency VLF detector is often better. See all gold prospecting detectors.

Getting the best from a pulse induction detector

Swing slowly and keep the coil low, since PI machines reward a steady sweep. Because you dig every signal, a fast pinpointer and a strong digging tool save hours. Carry a magnet in gold country to pull iron trash and black sand from the hole. Expect shorter battery life than a VLF, and carry spares or a charger.

Questions we get asked

Is pulse induction better than VLF?

Not overall, just for different ground. PI excels in mineralized soil and salt water; VLF gives better target ID and is lighter and cheaper.

Can pulse induction detectors discriminate trash?

Most can't, or only roughly. Expect to dig more targets, including iron and foil.

Are pulse induction detectors good for beginners?

They're simple to run but can be tiring, since you dig everything. Most beginners start with a VLF unless they hunt difficult gold ground or salt water.
