This machine is going nuts! The frustrated wife said. And it was going nuts over and area about a foot wide and maybe a foot long. After showing her how to wiggle the double D to pinpoint at the top of the coil instead of using the pinpoint function. We started to sort out all those noises, they were those good high pitched sounds with the cursor in the upper right of the screen. We ended up taking 9 clad dimes out of that area. That old XS is not nuts after all.
