Take a traditional approach to calling ducks this season with the time-tested design of the Rolling Thunder Game Calls 45 Cutdown Duck Call. This old-school, single-reed Louisiana cutdown design features a 45 blunt end on the toneboard to deliver a little more rasp and bark than the Original Cutdown Duck Call. A call design that pushes the air under the reed for a sharper sound, this call still delivers all the big volume of the Original Cutdown. Cancer and Reproductive Harm- www.P65Warnings.ca.gov.
