This call was built for one thing and one thing only KILLING DUCKS, NOT CALLING JUDGES. This Single Reed Duck Call is a Poly-Carbonate Insert with a Acrylic Mouth Piece or Wood. This call is capable of making all of the sounds of the Mallard Hen from her low soft raspy quacks and chuckle to the loud hails for those high flying migrators. Each call is Hand Tuned one at a time. This call was built and designed with help from Hardcore duck hunters who demand one call that is capable of killing ducks on any given day in any condition. This call has had major success in high pressure Public Hunting Areas.
