Duck Commander has always had a simple PHILosophy in making duck calls. Simply put - to make a call that sounds exactly like a mallard hen. Over 40 years of call building experience has led Duck Commander to produce the Jase Robertson PRO Series. It has unmatched range to get loud while also being soft enough to make perfect cadences for finishing on the quietest of days. The Hi-Ball call has a shortened polycarbonate barrel and reed combination requiring less air resulting in a great sounding call that unexplainably easy to blow. Also, the polycarbonate call does not swell or shrink with the changing weather conditions of duck hunting. This call is great sounding and the most affordable call in the PRO series lineup.
