The Wood Duck Hammer is invaluable during early season wood duck season, as well as during the regular duck season. This call is very easy to use and, with a little practice, you will replicate the contented whines and social whistles that wood ducks make while resting on the water. We beefed up the wall thickness of this call to make sure the Wood Duck Hammer is durable enough to withstand long seasons and years of abuse.Specifications and Features: Material: Polycarbonate Number of Reeds: 1 Species: Duck
