ABSTRACT:
A combination deer-predator call has a casing divided into upper and lower half sections held together by end caps. A pair of hinged flaps at opposite sides of the upper section form movable mouthpiece portions which define with adjacent lower casing portions mouthpiece openings which lead into an interior air space of the casing. Air blown through either opening passes across one of two elastic bands each stretched between an end portion of the casing and a corresponding slide positioner to produce an animal-like sound. The pitch of the sound produced by each band is varied by moving the associated slide positioner along a positioning slot in the casing to different retention slots. Each flap, when pressed inwardly, clamps its associated band in one of several variable stretched positions as determined by its slide positioner to produce a clear sound of the selected pitch. When released, the flaps enable the tension in the operative portions of the bands to be changed by the slide positioner. Each band is of a different size so as to have a different basic pitch than the other. The interior of each upper and lower half section of the casing is a complex arrangement of lands and relieved areas to provide the necessary airspace, guideways and clearances within the interior of the casing to enable the bands to produce the desired sounds.
