A triple reed batwing. 
This call has a thinner top reed followed by double prop reeds. Raspy front end with a clean break and an all around natural yelp. Effortlessly transition from yelping to cutting to purring this call can do it with ease. Afraid he can’t hear you don’t worry that prop can hang. Go ahead and yell at him from another ridge or across the field he will hear you and start a running.
