I was wondering if anyone has had any personal experience with these two coils on tiny nuggets. The 8x6 mono nugget finder, and the 7x12 mono nugget finder. I am thinking of buying a 7x12 mono coil as my "go to" small coil for my gpx 4000, and am hoping the 7x12 will not give up any tiny nuggets since it has more coverage and should go fairly deep on small nuggets as well. Any experiences? I will be hunting the outback of nevada, so lots of sage brush, rocks, so need an elliptical to get into tight spots with.
