All of our calls are made of Hardwoods carefully selected to give you the most realistic Deer vocalizations. This 5 in 1 adjustable call has an internal O-ring that can be repositioned along the toneboard to make diffrent deer vocalizations, including Mature Buck grunt, Young Buck grunt, Doe estrus bleat, Doe bleat, and Fawn bleat. The wood is sealed and tested to provide a long lasting finish even in the harshest of Deer woods.
