The Echo Acrylic ODB(Old Dirty Breaker) is the newest edition to the Echo Lineup. It blows loud for longer distance calling, but still comes down to a soft close in quack. Perfect for an all around duck call. This Call is the Swiss Army Knife of duck calls. It is so easy to blow and is able to make Cajun squeals and bouncing hens. This call has incredible range from top to bottom.
