GH's pattern, Nickels set for a high tone, Manual sens as high as I can run it, open screen, small coil, 99% on house and business demo lots I get the feeling the high manual sensitivity makes for a more scattered ID numbers. When I try to run in Auto, auto +3, I rarely get depth over 3 or 4 inches but the numbers are much more accurate. Very very slow sweep speeds.
Memorials come in from 34-43, with the cruddy rotten ones coming in at anywhere from 34-39. IH at 34/35, wheats from 38-42, clad dimes at 43/44, silver dimes usually at 44/45, clad dimes will almost always be at 43 on the sweep then pin point at 44. Quarters-clad at 44-46, silver 45-47, nickels will be usually FE11/12 and CO 11-13.-12/13,
Have dug Mercs a with a sweep hit at 12-39/40 and pin point at 44-45.
All good dug targets had a smooth high pure tone, with the cruddy memorials being a bit more splotchy hoarse sounding.
