That's a very, very nice button. What I have noticed is every time a different machine goes over the same spot, more stuff comes out. A couple years ago I went to a park, a rarity for me, a local club pounds. None of those guys uses a Deus, not then at least, I'm not sure now but they are fairly rare around here. There were remnants of dig holes everywhere. I pulled out several silvers, an 1864 Indian, and about $4 in change in about an hour and a half until I got bored. I have gone behind myself with a different machine, same thing happens.
