The Echo Poly Timber Call is excellent when hunting areas such as the green timber. These calls are made from a hard bullet proof plastic called PolyCarbonate. These calls are designed especially for close-in calling. They are straightforward to blow and produce a sound that is irresistible to ducks. These calls are made in Arkansas about an hour away from Echo's duck call shop, assuring you that these calls are made in the good ole U.S. of A.FeaturesPolycarbonate constructionDesigned for close-in callingStraightforward to operate
