[QUOTE="gcause, post: 87212, member: 1497"] Hi Peter, The coils you have are fine for general detecting on a goldfield rather than on a heap. A larger coil is usually used to locate a patch at depth. Mostly monos are used for that. Like coilteks UFO coil. Having said that a lot of small subsurface gold has been found with large coils like the UFO. DD's are great as well but you will lose a bit of depth, not much really, but you do get the benefit that they are quiter than a mono on highly mineralised ground. The best all round mono in my limited experience is the 14" coiltek round solid. But you may also want to look at the newer Litz wire monos like the nugget finder range. The smaller 6" monos are used to clean up a patch or where terrain like long grass is a problem. They are good for finding small gold close to the surface. Hope it helps :D [/QUOTE]
