Can a Metal Detector Find Meteorites?

Meteorites fall into three broad types. Iron meteorites are almost solid iron-nickel and detect extremely well. Stony-iron meteorites are a mix and still detect, though less strongly. Stony meteorites (chondrites) — the most common type to actually fall — contain little to no free metal and are difficult or impossible to find with a standard detector.

In practice, this means a metal detector is a genuinely useful meteorite-hunting tool for the iron and stony-iron types, and close to useless for the stony ones, which have to be found visually instead.

A meteorite's iron-nickel content reads in the same low target ID range as rusted iron trash — nails, wire, scrap. Every detector's default discrimination is built to silently reject exactly that range, because in a park or field, it's almost always junk.

That means a detector running its normal park-hunting settings will actively filter meteorites out without you ever hearing a signal. This is the single biggest reason people assume detectors can't find meteorites, when really the setting is just tuned against it.

Meteorite hunters run all-metal mode (no discrimination at all) with the iron audio feature on if the detector has one, so every target — including iron — produces a tone rather than being silently rejected. This is the same principle relic hunters use; see our relic hunting detector guide for machines built around genuine iron audio.

Pulse induction detectors are especially popular for serious meteorite hunting in mineralized desert terrain, since PI ignores ground mineralization entirely and has no meaningful discrimination to fight against in the first place. See our VLF vs pulse induction comparison for why that matters.
