Riven Menace Features The Riven Menace uses a bite and blow design that produces a rich nasal cow elk sound giving hunters a realistic tone that appeals directly to rutting bulls. Its custom tuned tone board is engineered to resist sticking and deliver flawless performance across a wide range of temperature and moisture conditions in the field. Because the call is built from tough polycarbonate rather than more fragile materials it stands up to the rigors of a hard hunting season without cracking or wearing out. This external reed design also makes the Menace far easier to master than a traditional diaphragm call lowering the learning curve for hunters new to elk calling. An adjustable O-ring lets the user fine tune the reed tension dialing in the exact pitch and volume needed to match different calling situations throughout the season. The included adjustable lanyard keeps the call within easy reach around the neck ready to use the moment a bull responds. Hunters who have struggled to produce consistent realistic sounds with a diaphragm call will find the Menace a far more forgiving and reliable tool in hand. Backed by two years of focused development the Menace is built to help hunters call bulls in close with confidence.
