This weekend's show had ol Tom and his son out on an Arizona claim near the Bradshaws. His son was using an X-70 with the stock coil and found a really nice chispa. Lots of gold on the piece of quartz. Tom was using a ML PI unit and found a smaller one. It sounded like his kid was not using the prospecting mode, but regular mode, and no headphones. It was a great find made by his kid. The 70 really did it's job well.
Good hunting, John K
