As condition vary from State to State and imagine in foreign countires another world so why argue...My feeling with perhaps the exception of a CZ or Wilson Coin & Relic the more you discriminate you lose depth, also running wide open you hear the goodies along with the junk next to it and perhaps get that super find everyone walked over before you..again whatever works and its noisy and perhaps feel John Sousa's band is following you around but one adjust quickly with time in the field..I love to see some of the nice discriminating screens some of the fellows come up with but are they applicable to good depth and stability not to mention the constant nulling..
