Small sized duck call with big soundProduce the higher pitch, squeaky sound of a young henSingle reed designAcrylic bodyEasy to operate The only thing small about the Rich-N-Tone Microhen Acrylic Duck Call is its stature. Standing in at a whopping 3-3/4″ tall, the Microhen was developed to produce the higher pitch, squeaky sound of a young hen compared to the deeper, raspier sound of an old boss hen. Because of the calls unique size, it practically drives itself? from its squeaky, prissy bottom end, to its top end hail call. Very little air is required to operate this call. You could say its micro in size, gigantic in sound. The Microhen provides a unique sound that can help fool even the wariest call shy birds. Material: Acrylic.
