This call is the SDS ( Song Dog Slayer) This call is extremely easy to blow and will make just about distress sound including bird and pup it will even do a good Howl, it is the second to the loudest distress call I make, its great for wide open country. The call is made from cocobolo and it might have some sapwood, which I really like, I think it adds to the call.. This is not the exact call you will receive just a represenative of it.
