Good questions Michael.
If this turns to be workable (which i doubt much) than it will start "revolution" in metal detecting world. Reading your posts, on this forum, Geo, i have impression that you are serious man, not just ilusionist like few others. Further i expect from you (i guess many others too) to more detailed explain your experiences with that device. Beware! Be honest or you may risk to be taken as charlatan in future. So far you look like honest man.
Regards!
