The Riven "Stratum" Diaphragm Elk Call is a premium, hand-tuned mouth call engineered for layered, realistic elk vocalizations with outstanding depth and versatility. This double-reed call produces rich, resonant cow mews, estrus whines, soft lost calls, calf sounds, and subtle herd talk—perfect for mimicking natural elk interactions and drawing in wary bulls during the rut.
The "Stratum" features dual latex reeds with a precision-cut design that delivers smooth, low-pressure airflow for natural-sounding tones while still offering the power and volume to carry through thick timber or open basins. Shines at close-in work, calming pressured bulls, or creating realistic herd sequences when paired with bugle tubes or frame calls.
Compact, lightweight, and ready to use straight out of the package. Whether you’re hunting public land or private ground during archery or rifle season, the Stratum delivers authentic cow and calf sounds that turn hesitant bulls into committed shooters.
