Zink Green Top Rocker Features The Zink Green Top Rocker uses a single reed design to produce a lot of volume along with a distinctive nasty nasally duck sound that carries across open water. That tone is engineered to mimic the sound of multiple hens calling at once which helps convince wary ducks that a flock is already working the area. The Z-cut tone channel is built into the call specifically to eliminate reed lock a common problem that can mute a call at the worst possible moment. This keeps the Green Top Rocker producing consistent sound call after call even during extended hunts. Finished in a black stealth color the call blends into a blind or boat without drawing attention. Its single reed design makes it approachable for hunters still developing their calling technique while still offering enough range for experienced callers to layer in variation. The call s volume and realistic tone make it well suited for open water and big spreads where ducks need convincing from a distance. The Zink Green Top Rocker gives waterfowl hunters a dependable loud voice in the blind.
