The Terminator Elk System consists of the Terminator Elk call that features a cap and extra reed compartment, 2 blue Terminator Elk reeds that pop on to the call and 2 latex reeds. The Terminator Elk Grunt Hose features a camouflage cover, lanyard and instructions. The system is a variation of a tube-type call featuring a first-of-its-kind mouth piece that enables you to produce bugles and cow calls quickly and easily with very little air pressure.
