Overview

Built for hunters who want a mouth call that can produce both bull and cow sounds, this option is aimed at close-range elk calling situations where control and realism matter. Its large-frame, non-dome chassis makes it a bit more demanding to run than a domed style call, so it suits users who are comfortable putting in some practice. For hunters willing to work with it, the design is intended to deliver a wide range of vocalizations from a compact diaphragm call.
