I was hunting a school that I have hunted for 3 years, it really is cleaned out. I was using my 10" EX. I hunted for 1.5 hrs and found 2 quarters and a zinc penny. It's not like my clad spot. I got a 24 VDI and the MXT said 10". I took out the pyramid shaped plug the depth of my Leschi blade which is 7+ inches. I then took out another chunk of dirt and there it was a 44 P War nickel. Rob
