Bought my AT Pro in July. I am experienced with detectors, however need help/advice with this one. Problem is with discrimination. Here is situation - (when running in Std. or Pro mode). When using the factory settings, I still have the same problems. It sounds off as if reading coins, 75-95 on digital readout, and the notch pointer goes to 75-95 as well. With iron audio on I still get the high tones and readouts, as well as low/mid tones. When I dig 6-8 inches I still find nails and other iron junk. Even more, when I move the iron disc. to max @ 40, and notch out all the way to 55, it doesn't change. Usually set sensitivity at 2 under max. Going to Zero mode in Std. or Pro doesn't change. Using 8x11 DD coil and auto ground balance. What am I missing here? Appreciate any help ! Thanks Len - Reno

What you are describing with Iron Audio On is the Tone Roll Audio. When you hear the high tone with the low tone on both sides....usually rusty iron or bottlecap. Now, it you have a high tone with a low tone on only one side, dig it. It might be a good target being masked by a rusty iron one.
