Riven RS1 Features The Riven RS1 is a mouth call built from tape and latex materials that allow it to reproduce a wide range of elk vocalizations from strong bugles to the full spectrum of cow sounds. Its domed shape is designed for consistency and ease of use helping hunters produce lifelike sounds with less practice than many traditional diaphragm calls require. The durable tape construction withstands the saliva and repeated use that come with long days in the field during elk season. Because it is a mouth call it leaves the hands free for gripping a bow or rifle which matters when an animal is closing the distance. Finished in Black and Blue the RS1 is sized to the adult standard used across the elk calling industry making it a drop in replacement or addition to a hunter s existing call lineup. Its acoustic dependability is aimed at hunters who need a call they can trust to deliver the right sound under pressure whether locating a bull at distance or closing in during the rut. The call s simple durable design means it can be carried easily in a pack or vest pocket without concern for damage. For elk hunters looking for a reliable easy to use mouth call the Riven RS1 delivers the range and consistency the season demands.
