I have no problem pinpointing with the Pro coil whatsoever. I just got the 12/10 and the first thing I did was to put coins on the ground and tried the same methods and I can see how this coil reacts. The problem is out in the field with multiable targets under the coil it becomes a real pain. Is there any hot spot on the coil that can be used? I have found 2 sofar . I'm about ready to sell this thing, its taking way to much time compared to the Pro and right now I'm not all that impressed with it. Someone please tell me if there is a trick to it.
