I'm curious if anybody has seen the xterra pro video floating about the ole web. The vid shows 4 big 1oz type silver coins, making the xterra pro to sound off like iron. The machine is 10khz, but i dont know what program. Would the 4 big silvers cause the machine to have wrap-around because of the big silver coins high conductivity. I'm wondering if it would do it in the other settings? Like 5khz? Or any other khz/program for that matter. Thanks.
