Hello all, I'm getting ready to order my new xp (after lots of research) And can't make up my mind on which coil package the 9' or 11' Most of my hunting is for old coins at old house sites or parks and sidewalks. I understand the 11' coil MAY be a little deeper but the 9" MAY be better in trash ?? It seems most of my sites have a fair amount of trash so I'm thinking the 9" but at the same time I don't want to lose any depth that the 11" has. TIH and happy hunting
