The Two-Faced truly is a "double threat". The two chambers give you the ability to operate two totally different calls at once. Utilize the aggressive grunt and an Estrus bleat when the rut is in full swing or adjust the reeds to mimic two different bucks about to spar in the early season. Both chambers are fully adjustable and capable of producing sounds ranging from a fawn bleat to mature buck grunts. No need to carry multiple calls to replicate two different deer, just use the Two-Faced.
