Diaphragm Mouth Calls-Why?

[Gobble Nole]

What is the trade name of the Halloran Split V? 

I went on his website and there are a few for sale with different names...

Even after 40 years of turkey hunting, I do not consider myself a very good caller. When it comes to mouth calls, I prefer the simplest of all, a single reed, usually a Perfection red. Same call I killed my first bird with in 1979. I can use multiple reed and raspier calls, albeit with more effort, but more often than not, my mouth call is used as a closer, and I can call very softly and with complete control with a single, thin reed, something that is difficult for me to do with multiple reed calls.
