About the only time I use a box call is when trying to locate a bird. After that, it stays in my leg pouch. After that I'll grab a slate/aluminum/glass call and go after him with that. After I'm set up, and hopefully when he's headed my way I'll slip the mouth call in and finish him off.

So basically, my opinion is start with a box call and get good at it. It shouldn't be hard to do as I think it's the easiest call to work. Then go for the slate type calls. Again, I think these are very easy as well. Almost as easy as the box call. Then go for the mouth call. Definitely the hardest call to work but probably the deadliest too. Good luck! Simp
