Native Super Tramp Double Glass Turkey Pot Call - The Super Tramp is a glass top over a glass soundboard that makes turkey sounds like it should cost twice as much as it does. A built-in simple walnut pot that's 3.25in diameter takes up less room in your call vest and is more comfortable in the hand. Native recommends 80 grit sandpaper or a medium grit sharpening stone to rough the surface. The Super Tramp comes paired with a single-piece striker.
