Try setting disc one in AM VCO. Disc two will still operate in disc. I was playing with this in the yard and getting very good results. I told a friend. He took it to a place that is known for beinghard to hunt. Most people only find stuff there now with a PI machine. He used the stock concentric coil and in testing it at first he dug some square nails. Then he began to trust disc 2 more and dug 4 minnieballs and a shell frag that in has words "almost blew his head off with the sound. I'd use headphones with a limiter if you do this. It will be goo to try in those places where the PI (InfiniumLS and White's TDI) hunters are the ones findingthe goodies. I tried it today on a quarter at 8" that I have trouble hitting with any machine because of some close iron. the AM VCO hit it like it was on the surface and disc2 hit it good on ok on foil and gave a chirp wide open. I think it is a good way to try the Tejon in bad, or any, gorund.e
