Never cared for the Lynch single sided "Fool Proof" box call....I often wondered why he named it the "Fool Proof".

Did he mean the call was fool proof on turkeys or that even a fool could call a turkey with it.

I have his old 45 records transferred onto CD....listening to him play the calls it's obvious to me the "Jet Slate" was "his caller".
Take the time to learn how to hold the call and softly play one and the Jet Slate is a killer call.
