Impressed is all I can say. ID, sound and seperation is grt. Pennies dont bounce all over the place. Things ID where they are suppose to. Hunted for an hour and a half at a spot that has been gone over by many hunters and still got the Merc at 6". Clear as a bell too and surrounded by slaw! If you dont order Andy's book on these MD's your missing the boat. Has cleared alot of questions up for me and Ive been able to pull targets that eveyone has missed. Sure cut the learning curve in half. The 11" is a grt coil but this one fits the area I hunt.
