The Riven "Black Ice" Diaphragm Elk Call is a high-performance, hand-tuned mouth call built for realistic and aggressive elk vocalizations. This single-reed call produces deep, raspy cow mews, estrus whines, lost calls, and calf sounds with exceptional tone, volume, and control—perfect for cutting through wind and distance in Colorado’s high country.
The "Black Ice" features a black latex diaphragm with a precision-cut design that requires minimal air pressure for smooth, natural sounds while still delivering the power needed to challenge rutting bulls. Easy enough for beginners yet offers the nuance and range experienced callers demand when working herds or locating satellite bulls.
Compact, lightweight, and ready to use out of the package. Pair it with a bugle tube or frame call for layered sequences that mimic real herd dynamics. Whether you’re hunting pressured public land or private ground during archery or rifle season, the Riven Black Ice delivers the authentic cow talk that turns bulls into committed shooters.
