The problem is, I dont think there is such a thing, at leastone thats 100% "jakeproof". The only thing I can think of that theyre referring to is a gobble-type call where you simply shake it and it makes a gobble. Its made of rubber and yes, a 6-year old can use it. But overall, thats part of turkey hunting. You really cant "NOT" call in jakes. I mean, they respond to the same calls. I know its frustrating, but like i said, its part of turkey hunting.
