The Duel Bite N Blow Elk Call features Dual Chamber Technology that gives you a competitive edge over all other elk calls, bugles or cow/calf calls. The advantage of realism is especially important when hunting animals that hear a lot of calls. You'll be amazed how well Duel Elk Calls work when no other calls get a response. Features an easy to master bite call that mimics cow's high to low mew sounds. It has an extended nasal cavity for added call resonance. Includes a lanyard. Made in USA.
