how to make metal detector

how to make a metal detector?/how does a metal detector work?/what are the components required for making a metal detector?/how to make a cheap and affordable metal detector?

Description: this circuit  most useful for security checking.Metal detector available in the market are quite expensive 

This metal detector can be used to detect slightly big size metallic objects.It uses a sensing coil.This coil should be kept near metallic objects for detection.Input of circuit is a weak clopitt's R.F. range oscillator. Sensing coil forms parts of tuned oscillator.

When coil is brought near a metallic object magnetic energy is absorbed and oscillator fails to work. then Final transistor conducts and buzzer is activated. use a 9V battery, after connecting battery, adjust 4.7K preset till circuit just stop sounding
