walk through metal detector schematic diagram

Guys could anyone have a related subject sites or links or anything concerning

a walk through metal detaector, specially its schematic diagram could u plz pass it to me.

This is not the metal detector that is used to detect metal or mine in the ground, i want the on that is used in the airport, and the embassies.
 

walk through circuit

I guess it's just the same, as mine detector.
The difference is the coil, which is much bigger to let you pass through it.
 

Thanks Verba for the reply,
