Riven RS1 Elk Diaphragm Mouth Call Bull/Calf/Cow Black/Blue

The Riven RS1 is a compact elk diaphragm mouth call built around a single small-dome reed frame that delivers convincing bull, cow, and calf vocalizations in one call. Designed for hunters who want acoustic consistency and tonal variety in the field, this reed-based call lays down lifelike elk sounds with impressive ease and precision, producing low, medium, and high tones with tremors, chuckling, and screams across all three sound profiles.

The diaphragm sits inside the mouth for hands-free operation, leaving both hands free to manage your rifle, binoculars, or rangefinder while working a herd bull or calling in a cautious cow or calf. The small dome promotes consistent mouth placement in any calling position, helping both new and seasoned elk hunters get repeatable sound production without fumbling with an external tube or pot call.

Finished in a high-visibility black / blue color scheme, the RS1 is easy to spot in your pack when the action heats up. Lightweight and reusable, this mouth call is a versatile staple for western elk hunters who want a single call that can shift between bull, cow, and calf vocalizations throughout a single hunt.
