The Bulldozer is the most versatile Moose call on the market today! It will reproduce the mating bawl of the Cow, lost call of the calf and guttural grunts of the Bull Moose, with very little practice! The Bulldozer also has a water resistant calling surface that will work in most weather conditions. This call can also be used as an air operated cow, calf and bull call by simply using your vocal cords, placing the smaller end to your lips as if you were using a Birch Bark Horn! Includes instructional CD.
