First off, when you dig "trash" you are supposed to pack it out with you and throw it away, that's just good manners and MD ethics.How do you all deal with things like aluminum cans? They seem to register as good hits, and because of their size give strong signals, but many times when I am 6-8" down its a can, and because I did narrow holes it can be a real chore before I determine its a can or not. Second, I have leaving anything in the ground, as I may lose track and try to dig it some other time :/
