The Eddie Salters Predator Call is designed to reproduce the distress call of a Cottontail Rabbit. The call is very effective for calling Coyotes, Bobcats, Fox, Racoon & other such predator species. The call is mouth/diaphragm air operated. It can be operated by exhaling on the lanyard end or inhaling on the smaller barrel. Lanyard is included. It is old new stock from the 90's. Feel free to ask question. Thanks GP
