The Riven RS2 Small Dome Diaphragm is a precision mouth call featuring a small dome frame designed for hunters with narrower palates. This design provides a secure seal to eliminate the gag reflex and enhance air control. Its precision-cut latex offers increased resistance and volume while remaining extremely reactive, allowing for a full range of low, medium, and high tonal vocalizations. This durable, hands-free call is specifically engineered to produce consistent bull bugles and realistic cow or calf mews, making it a versatile tool for Rocky Mountain and Roosevelt Elk hunting. Safety Note Diaphragm calls are small oral devices; always inspect the latex for damage to prevent choking hazards and maintain situational awareness as realistic elk sounds can attract other hunters or predators.
