The Riven Elkasus Small Dome Diaphragm is a precision mouth call featuring a small dome frame specifically designed to provide a comfortable fit for hunters with smaller or narrower palates. Constructed with durable, heavy black and white latex, it is engineered to produce smooth, realistic cow and calf vocalizations that stand the test of time. This versatile, hands-free call creates a full range of nasal tones, including mews, cow bugles, and estrus buzzes, as well as the high-pitched pips and screams of younger bulls. Its specialized fit ensures a superior seal against the roof of the mouth for consistent, high-quality sound across low, medium, and high tonal ranges. Safety Note Diaphragm calls are small oral devices; always inspect the latex and frame for damage to prevent choking hazards and maintain 360-degree awareness as realistic elk sounds can attract other hunters or predators.
