Swing that coil! You'll love the 6x10, it's my favorite for my DFX and the 4x6 shooter is my favorite for the Prizm IV... DD coils really are the best overall coils.
The only trick is learning pinpointing. Swing it left & right to find the strongest signal then forwards and backwards. Once you find the loudest spot under your coil, pull the coil straight back and just when the signal falls off the target will be under the front tip of the coil.
