Hardware costs and manpower costs. Portal metal detectors vary widely in price. Portals on the market range from as little as $1,000 up to as much as $30,000. The moderately-priced models around $4,000 to $5,000 probably offer the features and reliabilities required for a school metal detection program. Models closer to $1,000 are not recommended due to lack of sensitivity of these devices.
A metal detector is an electronic instrument which detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. They often consist of a handheld unit with a sensor probe which can be swept over the ground or other objects.
