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.
The industrial metal detector was developed by Bruce Kerr and David Hiscock in 1947. The founding company Goring Kerr pioneered the use and development of the first industrial metal detector. Mars Incorporated was one of the first customers of Goring Kerr using their Metlokate metal detector to inspect Mars bars.
