Duck Commander’s Pro Series Hi-Ball call has unmatched range that gets loud while also being soft enough to make perfect cadences for finishing on the quietest of days. The Hi-Ball call has a shortened poly barrel and reed combination requiring less air resulting in a great sounding call that is unexplainably easy to blow. Also, the poly 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.
