The Bird-X Mega Blaster PRO is a powerful sonic bird control system that uses intermittent distress calls to create a danger zone that frightens infesting birds away for good. Customize settings: you control eight sounds, volume, and intervals. Two high-put amplifiers drive the 20-speaker tower, repelling pest birds across up to 30 acres of open land. Perfect for airport property, airfields, and other large outdoor areas. Prevent pest bird infestation around airports; reduce bird strike hazards and costly damage to aircraft and equipment.
