Riven Origin Series Elk Diaphragm Features The Riven Origin Series 3-Pack bundles three of the brand s best-selling non-dome mouth calls each engineered to mimic a different piece of the elk vocalization spectrum. The Single Lady call is tuned to produce unbelievably realistic cow elk sounds delivering sweet and smooth cow and calf vocalizations that make it a must-have for calling in curious or lonely elk. The Black Ice call targets advanced callers who want maximum tonal range and acoustic realism built on a large frame non-dome chassis that takes slightly more practice to run than a domed-style call but rewards the caller with a truly versatile voice. The Stratum call completes the trio with remarkable bull and cow sounds from the same large frame non-dome design philosophy. Made from a tape and latex construction each call in the set is built to hold up to repeated use across a full hunting season without losing its tone or durability. Being a hands-free diaphragm style call each one lets the hunter keep both hands on the bow or rifle while calling a critical advantage when an elk is closing the distance. Packaged together in one 3-pack the set gives hunters the flexibility to switch between three distinct voices depending on the situation and the response they are getting from nearby elk. For elk hunters who want a complete versatile set of mouth calls in one purchase the Riven Origin Series Elk Diaphragm 3-Pack is available for sale at GrabAGun.
