Abstract
Metal detector's is getting more and more widespread in modern life application。From the first application in mine detecting and the survey underground metal,it is starting to develop to present's food, the ready-made clothing product, the rubber, aspect woodworking and so on. They all applied in qualities safely examines, its function appears more and more useful, at the same time in the function enhancement and the consummation also more and more receive the general customers attention.
