When we think of metal detecting, we typically think of the individual with
his metal detector strapped to his arm, headphones on, and walking a beach or public park. But the field of metal detecting has become far more than that.

Humanitarian De-Mining
In areas where wars have occurred and explosive mines have been planted but not yet detonated, metal detectors have been used to locate and defuse them. Metal detectors are also being used in the war in the Middle East by soldiers to detect and defuse land mines. These machines weigh less than 5 pounds; their heads on the ground are 2 feet in diameter so as to cover sufficient depth and reasonable scanning surface and speed. They can detect up to 10 feet in depth, work on a 10-hour battery, and have an output sensory that detects the mine without the surrounding shrapnel.
Civil Engineering
Steel bars reside within large slabs of concrete, which are used to build bridges,
highways, dams and other large structures within a city proper. Metal detectors
have been developed using a Ferroscan system to detect these metal structures
within the concrete after years of use to examine their structural soundness.
This aids civil engineers in localizing and interpreting the underlying metallic
structure and allows them to see rather than having to make an educated guess.
