I would like to build a metal detector capable of detecting only Ferrous metals with a range of at least 3ft.
This would be for a commercial application and not for treasure hunting.
Does anybody have any ideas as to where I could get information on the construction of such a device-schematics, parts etc.
Any help would be appreciated.

John D
