Echo acrylic open water duck call is great for longer distances when hunting on big lakes or open fields.These calls generate a ringing hail call that will attract ducks at several hundred yards, yet they are also very ducky, and blow soft when the ducks are in close.It has a loud raspy quack, and a real nasty hen sound that ducks really flock to.Calls: DucksSpecies: DucksMaterial: AcrylicSound Species: MallardElectronic: NoColor: BourbonStyle: Single ReedHands Free: NoSounds: Mallard
