This call accurately imitates the growls, grunts, and squeals of the javelina. Javelina have in the past responded to predator calls but with limited success. Javelina are not predators so why do they respond to predator calls? We know that they communicate with each other all the time. With this in mind we developed this call to specifically imnitate their language. Javelina are extremely aggressive and will defend their terrirory against intruding javelina. By imitating the vocalizations of javelina you are basically invading their territory. This type of calling has proven to be extremely effective. Includes custom camo lanyard.
