Dmar, the old adage you get what you pay for. I read your post on nails in the hole. Believe me, most know your frustration. Minelab Pro 35 was designed to help deal with that, two tones, one ferrous and one nonferrous. Concept great, in practice not so much. Mine still sits in the box. With air tests it doesn't begin to distinguish between the two until a half, maybe three quarters of an inch. That said, when I've got a plug open I will clean it out and sometimes something good shows up but you get a lot of rusty iron as well. My go to is a Garret At (carrot). Worth the money. Your clad haul for a year would most likely pay for it and then some. Good luck. Mark
