Modern Day Metal Detector Trends

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.
