Riven Black Ice Features The Riven Black Ice elk diaphragm call sits on a professional grade non domed chassis built for advanced callers who want more tonal control than a standard domed call offers. Its large frame produces exceptionally full bugles and realistic chuckles giving experienced hunters the acoustic range needed to work a herd bull. Durable tape and latex construction holds up through a demanding season of calling in the field. Because the non dome design is more challenging to run it rewards callers who have put in the practice with superior realism over simpler calls. Finished in black and white the Black Ice stands out in a crowded call pouch and is easy to identify in low light before first light. This call is truly world class built for callers who have moved beyond beginner equipment and want a diaphragm that answers every demand placed on it. Hands free operation keeps both hands on the bow or rifle while still delivering the volume and tone needed to close the distance on a mature bull. The Riven Black Ice Elk Diaphragm Call is a serious hunter s call for sale at GrabAGun.
