General-purpose metal detectors can find buried metal objects such as jewelry, coins and other metal objects. “Discrimination” is a process that distinguishes between different metal targets or alloys.

What does gold show up as on a metal detector?

The detectors that are best at identifying gold are multi-frequency or PI-type detectors. These are two of the most expensive kinds of metal detectors, but they have the best features for conditions that accompany searching for gold. That is because gold is nearly always found in areas of high mineralization.

Can airport scanners detect gold?

The X-ray machines at the airports could easily detect gold concealed inside the baggage of passengers. The latest metal detectors will help enforcers intercept carriers who conceal gold in their body cavities or on their person. The detectors will also be installed at the green-channel exits of the airports.
