Howdy Mark! Excellent question. My answer: with the Mini DD coil, gain at 10 (maximum for many areas) my MXT does not get a VDI response on nuggets less than 1 grain in size. A chunky one-grainer gives occaisional (once every few passes) VDI numbers of "0" (yeah, "0" IS a number) When the nugget hits the 1.5 grain size, there are CONSISTENT VDI numbers of "0" or "1". A two grainer gives consistent numbers ranging from "2" to "6". Larger nuggets give higher numbers, and tend to register repeated single numbers, with a slight "spread" of numbers. BUT.... these figures represent my soil, and my macine, and may differ from area to area, and machine to machine. As far as I am concerned, when huggethunting, all clearly non-ferrous signals get dug. By the way, ain't that little Mini DD a wonderful coil? HH Jim
