This deer call is designed with the needs of both the bow and gun deer hunter in mind. Patented inhale / exhale operation allows you to produce hyperventilating grunting sounds from the same end of the call for uniterrupted calling. Ergonomic mouthpiece is designed to eliminate mouth fatigue; rotating barrel adjusts out of the way for continuous deer calling when drawing a bow or shouldering a rifle. Includes lanyard. Produces a full range of grunt tones. Perfect for bringing the deer in those last few yards while keeping your hands ready for action.

That is exactly what it says on the K & H website when describing the call. Hmmm that's funny.

thats where i got it!
