PolyCarbonate Duck Calls are made from PolyCarbonate, which is a hard bulletproof plastic that will last years and years. Our PolyCarbonate Duck Calls come in 2 flavors: Timber and Open Water. They are extremely easy to blow and are great for beginners. We have guides who use these calls and swear by them. Have no fear; these calls are 100% American made 1 hour from our shop in Arkansas, which is part of the good ole US of A!
