The Riven Cosmic Combo Pack is a comprehensive elk calling system designed for maximum versatility and durability. This all-in-one pack includes three specialized small-domed diaphragm calls: the Comet, the Elkasus, and the RS2. Each call is engineered with a small dome frame to ensure perfect mouth placement and a better seal, especially for hunters with narrower palates. Together, these calls allow hunters to simulate an entire herd by producing a full spectrum of vocalizations, from aggressive bull bugles, chuckles, and screams to social cow mews, calves chirps, and estrus buzzing. Safety Note Realistic elk vocalizations can attract other hunters or dangerous predators like bears and mountain lions; always maintain 360-degree awareness and inspect each reed for damage to prevent choking hazards.
