To my knowledge, he never hunted with anything but a slate call or occasionally a glass call.
As a kid, I used to sit up at night and wait for him to call and ask if I wanted to go with him. It meant the world to me that he would always let me tag along with him. Because of that, I'm wanting something to let him know how much I appreciated him and how much of an impact it had on me - so I want something really nice that he would be proud of.
