I 100% agree with Diggin-N-Dumps. Std mode is not good, even for beginners. Go whole hog and jump into pro mode from the get-go. Atpro loves small things like shoe eyelets and bits of foil and can slaw, so you gotta watch your notch settings in the trash, unless you enjoy the punishment like me, I run zero iron and zero notch scrim in the trashiest parts of the park, I would not have it any other way. Atpro has excellent stability in iron trash, mine has mopped up more than a few stragglers in trashy areas beat up with every machine made. Atpro has excellent recovery speed and it has very good trash separation ability. You can work the coil pretty fast. At the highest sense settings, atpro has enough sensitivity to become a bit chattery around power lines, which is a good thing. Atpro will not miss a ten inch deep silver or clad quarter. I have recovered deep wheats and silver dimes up to 8" with solid high pitch, but perhaps that is approaching the limits of the machine, I wont know for sure until I get a ten inch deep silver dime, which could happen. John Edmonton showed air test charts on Tnet indicating that the big atpro elliptical concentric has a significant depth advantage over the big dd coil for those wanting that extra inch or two of depth. But for the trash, stick with the dd.
