Worked a Bulldozed lot today and set the F70 Sens at 80 Disc at 24, Thresh at -2 with Sharpshooter coil. lots of clad and a nice 1902 Barber quarter and 1911 Wheat and 1956 Rosie tried to post pics but keeps telling me file to large anyway finally starting to get the f70 to work for me more hours needed they are chatty until you can fine some good settings for the area the dime was only about 4 inches the quarter was well over 7 inches
