These calls are made from a hard bulletproof plastic known as PolyCarbonate. The Open Water call is designed for long-distance calling. It has a loud raspy quack and makes real nasty hen sounds that ducks really flock to. The Open Water call is available in 3 colors Bourbon, Smoke, and Green. Available in a single or double reed, and has a polished aluminum band. These calls are made in Arkansas about an hour away from our duck call shop. We can assure you they are made in the good ole U.S. of A.
