    Anyone made a metal detector?

    I'm planning on making one, and I found a very simple circuit. The problem is that this circuit transmits the signal to an AM radio receiver that you need to carry with you set at a certain frequency.

    Anyone knows how to improve this design so that it's all integrated in the same circuit, maybe with an indicator for depth, etc... or has anyone a better, yet still simple, design that I can make at home?

    I don't understand how this one works, so can anyone explain? (I can't even see where is the AM radio transmitter in there) :(
