Take along an aid on your next deer hunt when you use the Primus 729 Power Buck And Doe Deer Grunt Call. You can bleat and grunt using just one call when you use this device as a realistic sound effect. The Primos deer call lets you simply exhale and inhale on it to create sounds no deer can ignore. This is because it has a dual-reed assembly for inhale-exhale operation. The device simulates the throaty grunts and the clicking tones of aggressive bucks and also the Estrus bleats and cries of does. The hunting call gives you single- and double-reed options, and the all-in-one call includes a built-in compass.
