If anyone has doubts about the X-70 going deep enough, I dug a 1/2" button (plain, 2-piece) today at about 12 - 13". I had the 10.5 DD, running All - Metal, Sens. at 28 and TID at 30 with a good solid tone. I almost gave up on it thinking it was a large piece of iron that was deep. I finally found it with the pinpointer deep in the hole, lying flat. I also found my first 3-center today but it was the nickle variety, so it's a bit rough. I'll post the finds pic later, too tired to do the set-up but here is a view from the field. Ron
