Each call is individually turned and polished from cast acrylic and is laser-engraved. FUSION calls combine the beauty of acrylic and affordability of a precision polycarbonate call. The FUSION Acrylic Yo' Sista is an Arkansas style, single-reed call that features a small sound port designed for subtle calling, which is ideal for call-shy ducks or hunting in flooded timber. She is one of the sweetest sounding girls around.
