I use the Primos Hands Free Buck and Doe Model 717...........I shot a 10 point 2 years ago and he had an 8 point with him.........after the 10 fell the 8 ran into the cover..............I grunted a couple of times and the 8 came back to the same spot........man was that alot of dragging.

Knight and Hale also has a hands free call.........it works good also.

I have an old Primos Wood grunt call..........that thing is awesome sounding......it is loud.
