What gets me is why Garrett neglects to do anything with the Flagship GTI 2500? They first spend money on the ACE series...then make a Pinpointer(one of the best),AT series and then the ATX pulse unit. All the mean time doing nothing with the 2500. I wish Garrett would make a more deeper Discriminate depth GTI 3000! I really liked using the GTI series,but felt the depth in the Disc mode was severely lacking. About to 6" in my ground. The image sizing was out of this world! It was nice to know what size it was to dig. Garrett,are you listening?
