Its unique, dual throat design allows the caller to easily create many different styles of howls, barks and K-9 distress sounds. The caller can selectively use the top or bottom side to produce the sounds or use both sides at once. The sliding mouth piece easily adjusts to fit any caller’s lips for proper air flow. Although slim and compact, the “Yote Howler®” can reach coyotes over a mile away and is nearly impossible to tell from an actual coyote. Extra band and lanyard included.
