n 1972, Phil Robertson had a dream of creating duck calls that sounded exactly like a duck. That passion fueled the creation of a line of calls that left a mark on the hunting industry. If you were a fan of the Brown Sugar, this will be one of your favorite calls. With the RDC200, we have added a built in supressor to muffle the sound just enough to cancel echoes. It is easy to blow and ideal for flooded timber hunts. In a field setting, it would be a great finishing call.
