Has anyone tried the ACE 5"X8" DD coil on the ACE 350? If you have, what is your opinion on this setup? I mostly coin hunt in local parks with an ACE 350 and the standard 8.5"X11" DD coil. I was thinking the smaller 5"X8" DD coil would allow me to get closer to fences and equipment, easier pinpointing and lighter to swing. Any chance it would help with identifying bottle caps and screw caps?
