With sound waves that move from speaker to speaker, the Bird-X Broadband Pro bird repeller forces birds to leave manufacturing and waste facilities, rooftops, parking lots and towers, yet is harmless to animals and the environment.  The repeller targets birds with a combination of four sound types and includes three visual scares to frighten birds. One unit covers up to 10,000 sq. ft.
