Riven Cosmic Combo Pack Features The Riven Cosmic Combo Pack covers a full range of elk vocalizations from cow and calf talk to aggressive bull bugles chuckles and screams. Because the pack includes three distinct diaphragm calls the Comet Elkasus and RS2 a hunter can switch between sounds without carrying multiple separate packages into the field. Each call uses a small dome design that seats comfortably against the roof of the mouth making placement fast and consistent even under the pressure of a closing bull. Top quality tape and latex construction are built to hold up through a full season of hard calling. Every call in the set is hand built in the USA giving the pack a level of consistency that mass produced diaphragms often lack. A durable clamshell carry case protects all three calls from damage and moisture while riding in a pack or vest pocket between stalks. Having cow calf and bull sounds available in one compact kit lets a caller react to a bull s mood in real time rather than guessing with a single-purpose call. The Riven Cosmic Combo Pack is for sale at GrabAGun for elk hunters who want one complete hands free calling system for the entire season.
