Lip Service� drives Bulls crazy. It is a simple sliding note that has the high pitch of cows and calves. The Lip Service� gets its guts from our famous �Hoochie� MAMA� but can be manipulated to get varying pitches proven to call Bull Elk in close. This call is easy to manipulate and can be carried in a shirt pocket. Good things truly come in small packages. - Accurate Estrus� Cow Call - Compact fits in Shirt Pocket
