Primos has teamed up with Randy Anderson to bring you the Mouth Call Howler Pak. The Sonic Dome predator mouth call is used to create higher pitched howls. It has a natural skip that perfectly reproduces the interrogation howl that Randy uses to lure in wise old coyotes. The Double Howler predator mouth call has a deeper pitch, which is perfect for making the coyote's lonesome greeting howl. Both calls make the full range of coyote howls and distress calls. The megaphone is included to increase the range of your calling and give it direction
