The Champ 2.0 is a versatile call that produces small to medium cow, calf, and bull sounds, as well as a nasal cow sound and a high-pitched screaming bugle. The innovative "Slotted Dome TST" elk diaphragm call is crafted for comfortable placement behind your front teeth, reducing gag reflex and offering better latex control. To use, position the call with the "Slotted Dome" facing up towards the roof of your mouth, latex down, and the open end directed towards the front of your mouth.
