ABSTRACT:
A game call in the form of a diaphragm call includes an upwardly extending shelf which extends over a substantial portion of the latex membrane. The shelf provides a constant distance above the latex membrane to render the call easier to use and prevent the caller from damaging the latex membrane from upward pressure by the tongue. The shelf may be adjusted to vary the distance between the shelf and top surface of the latex membrane.
