The SGE (Skinny Goose Express) is a short reed Canada goose call. This call is all acrylic with an engraved anodized aluminum band. The SGE is available in 12 different acrylic acetate colors with a black acrylic keg. Easy to blow and true to the full throttle speed known from Final Flight Calls. The wide open exhaust gives you all the volume ever needed. The barrel holds a unique inner bore dimension of 11/16 of an inch. Truly a great tool to add to any goose hunters lanyard no matter the skill level.
