The Inhale/Exhale Deer call is a new update to the MAD Deer Call Family. It can produce an infinite number of grunts and bleats...Inhale to bleat, exhale to grunt...turn over to yield new tones - inhale to grunt, exhale to bleat. Center tuning hole allows user to alter grunts and bleats on the fly. It produces amazingly realistic calling sequences. MAD's patented "PTS" allows even further adjustment to grunt and bleat tones while always making it easy to return to the factory setting. Includes an instructional DVD produced by Mark Drury unique to the Inhale/Exhale with exciting footage of the Inhale/Exhale action.
