FOXPRO's Bittersweet pot call is a two-in-one call which offers versatility and realistic sound. The pot call is made from Honey Locust wood, offered in glass over slate, and comes with a one-piece Purple Heart wood striker. The Bittersweet is a tip-over call, meaning you are able to make a sound on each surface of the call. This gives you a slate call and a glass call all in one. Produce BITTER cuts, clucks and yelps on the glass side and SWEET purrs, puts and tree yelps on the slate side.
