These Instructions came from Huntingnets.com avid turkey hutning member - Wingbone.

He and I traded calls and he gave me these instructions to which I asked if I coud share with all of you. This is his work! Not mine!

Though Ias it is said a picture is worth a1,000 words and the text is hard to read - this is what is written.
1. Press Lips firmly together - insert call (1/4") between lips
2. Wrap thumb and forefinger around end of call
3. Fist formed around call to form an air chamber - leave gap with second finger
4. Suck air into call gently in a series of short sips, as if sucking on a soda straw. Adjust gap in air chamber to get a two-toned yelp by using that second finger - see picture attached

Thanks Rock!
