This is one of the finest hand made mouth calls on the market today. The Sutliff Wing was developed by professional caller and co-owner of Top Calls, Frank Sutliff Jr. The batwing cut added with the latex and prophylactic mix gives this call competition quality sounds. This call is a must for the hunter who wants to take their calling to the next level. This 3 reed batwing cut call has a .004 gray top reed and two .003 prophylactic bottom reeds.
