HI just thought I would drop you a note and tell you I'm in the lead and copper business. My goldquest hasn't missed a beat! 3 times out well over 75 holes and lots of wire and lead oh forgot I also snagged 11 pennies. The only control I haven't played with is the reject . Do you keep it as far left as it will go or should I move it to the first or second line . Any other suggestions. I did move it to the first line as someone suggested but I ran out of juice so I will have try some more thanks bill Anyone have any settings for this machine
