What To Look For in The Best Pulse Induction Metal Detector

We know there's lots of options out there - but don't worry, we're here to help you find the best pulse induction metal detector for you! Pulse induction metal detectors are best used in salt water, wet sand, and highly mineralized ground because they ignore the mineralization but maintain high sensitivity. Here’s what to look for in the best metal detector with pulse induction.

Waterproofing

If you’re planning on detecting in the water of any kind, waterproofing is important. A waterproof coil or a submersible PI detector is necessary.

Submersible Depth

PI metal detectors are ideal for wreck diving, but check its depth capacity out first. Water pressure can do Very Bad Things to circuitry and PI machines are not cheap.

Discrimination

Pulse induction metal detectors are immune to salt water and highly mineralized grounds, but sometimes they need an adjustment. This is when good discrimination is your friend.

Sensitivity or Iron Check

Iron check is a handy feature but not all pulse induction metal detectors have it. (The Deepmax Z1 does as does the Garrett ATX). Because PI machines don’t generally use modes having something to filter unwanted targets or trash is useful. Adjustable sensitivity is a proven way to filter out ferrous targets and unwanted metals.

Continuous Ground Balance Check

This is a feature only found on the best metal detectors with pulse induction electronics. A continuous ground balance check that readjusts itself accordingly isn’t essential but makes life easier when you’re striding between the ocean and dry sand.

Coil Size

The best coil size depends on your intended use. If you’re a wreck diver, snorkeller, or a surf detectorist then a small coil such as the 8 inches on Garrett’s Sea Hunter, or the 5.5 inches on the Pulsedive, is lightweight and easy to fit into small spaces between rocks. That said, a large coil such as Lorenz’s 14-inch DD covers more ground which is handy if you’re striding out in the gold fields. Look for options to swap out coils.

Conclusion

Pulse induction metal detectors are not cheap so its worth doing your research. The best pulse induction metal detectors listed above are all worthy of your money. They won’t let you down or embarrass you, and each has a band of followers. Choose the best PI metal detector you can afford and practice until you have it down pat. There’s no other way to maximize your finds.
