Metal & Weapon Detectors are extensively used to provide security to buildings and secure areas by scanning individuals for weapons and contraband. Most people will be familiar with their operation in airports, government buildings and banks, etc. Walk-Through and Hand-Held Metal Detectors are increasingly being used with great effect in shops, offices, theatres, nightclubs, sports stadiums, etc., indeed anywhere there are concentrations of people or where the risk of an attack is a possibility.
