I got a GPX 4500 and used it for the first time Saturday. It was a eye opening experience. I had a friend set it up for civil war relic hunting. It's deeper than anything I've ever used. I had the factory 11" DD coil on it. I found bullets below the plow line on top of and into the clay. It came with a 15"/12" SEF coil. What are you guys thoughts about that coil? My friend was using a Ultimate 15" DD coil that day and did really well also. Thanks
