You could do alot with the sound card to control the frequency, and measure the response.
Amplification is the fiddly bit.
Golddigger is it really a PI ?

That's entirely up to the person programming the sound card output. If you send a pulse out, have a delay and then read the response on the same coil analyzing the timing, that would qualify it as a PI unit. Using two coils, it could be set up as a VLF/TR unit. That's the seductive nature of using an ultimately reprogrammable system like a computer. In the original poster's  idea, he speaks of using a coil as big as a car. He'd have to have at least that much of a "life support system" for his PC to come along and to drag his huge coil around.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.
