I recently talked with Mike from VA. Beach about hunting a new site. An old mill from the 1700's, but I can't get my ExpII to settle down. Tried turning sens down to 18 and I.M.to -6. I still get high silver chirps every swing anywhere fron 3-6, but nothing consistent, the hits are all over the screen. But most far right. The ground is like black sand lots of pebbles and stones and a high iron content. It is next to a big stream. I'm digging all these signals and coming up with nothing, I'm blowing it!
