The Hobo ICU2 Acrylic Duck Call is a double reed acrylic call. The sound can still get loud or soft when you need it. The raspy whines and clucks make it an excellent choice for hunters. The ICU2 was used to win the 2009 World Live Duck Championship. This call will ring on the top and get low and soft. It blows easy and will give you the soft whines and quacks with a feed call that will fool ducks every time. It will give you the course, raspy sounds of ducks and still get the clean and nasally sound of Mallard hens. If you like a double reed, then you will love the ICU2 Acrylic Duck Call.
