Gobblers will cluck and make assembly call sort of noises... almost like hens will. Especially in the fall of the year. Only it is much deeper, and much more raspy.

You will, with practice, be able to make a gobble on your diaphram call in due time. Ain't really good for nothing except calling hunters... though I've used it to my advantage a time or two . Not all mouth calls will do it... but you'll figure it out.

Use the NWTF.org webite to reference your calls. They have free streams of actual turkeys calling. That is how I would learn if I were you! Good luck! Keep at it!
