im lovin the ctx i have been using the at pro since it came out ,what a difference,i went out here in r.i. today it got to 42 deg i went to the old hunted to death park and every target i dug had big chunks of iron or nails with it left by other machines even me and my at pro but there are plenty of goodies when running a ctx,i have been out with the ctx 3 times since i got it and have found 6 silvers a silver braclet and a ring ,,this is going to be a good summer
