The Primos Original Wench duck call features a sounding board with ridges and ditches on it. This unique design allows the duck call to have a raspy high or low pitch and keeps the call from sticking. In addition to the unique design the duck call also has a tuning hole in the bell or stopper, which allows you to change the pitch of the call and sound like two different ducks. If covered, the duck call is lower in pitch and uncovered it is higher. The duck call has a double reed and the barrel is molded from a super-hard polycarbonate. Perfect for mainstream waterfowlers the duck call also comes with a lanyard so it is ready to go.
