Speck call help

[Gasper Master]

Not arguing with you guys, but hes been hunting this blind for five years. he just learned how to call and started really killing geese the last two seasons. The three before he would kill a handful. I'm no expert, its just what i see and what he tells me. Its not that the geese "want" to come in there. The geese fly over this blind just as i have seen them fly over many others that i have hunted.
