This may be a silly question. I have had my F75 about 3 weeks and have done very well hunting the old house sites that today are bean and corn fields, Got some large cents, Indians, Barber dime, Good for tokens and lots of brass and copper. The farmers have put the crops out and the fields are off limits until this fall when the crops come out. We now have to go to the old parks, they have been hunted hard, But I am sure there are still some nice coins "Down There" Which I hope to find. My question is what settings on the F75 are people using in the parks that still have lots of pull tabs and screw caps. See I told you it was a silly question. Thanks. Lee-IN
