My step son came home today and wanted to play with my new dector. After a hour or so he asked me if i could make it stop making so much noise. Hes 13 and never detected before. I told him that it all metal that it is talking about. Of course he said it don't talk so i had to explain that it was talking just in a language he had not learned yet. He then began digging those beeps,grunts,and squeaks. One hole he dug with a target of 6 inches he could not find pro pointer wasn't beeping. He told me it was a blank hole so i told him AT PRO don't lie. I went to assist and showed him that the a AT didn't lie. This is a great machine with great depth. I have not found much of value but not for lack of trying.Would recommend to anyone from first timers like me or for someone have 50 year experience.
