Welcome from SW Ohio, ATpro is a great machine, had mine a few years and love it. Pinpointing tip for the ATP is to ignore the pinpoint button, faster and easier to use the wiggle back method, all that mean is when you get the target under your coil just wiggle it back and forth while pulling the coil away from the target. As soon as you lose the signal the target it will be right under the front tip of your coil. Good luck and HH.
