Birds can't stand these blasts - overlapping fans of ultrasonic sound in all directions - but people can't hear it.
 
No moving parts; continuous, maintenance-free coverage up to 6,400 square feet.
 
Programmable repeller can be adjusted for frequency, warble rate and speaker sequencing so birds don't acclimate.
 
Ideal for use in any enclosed or semi-enclosed area, like hangars, warehouses, plants, tunnels, loading docks, railroad sidings, breezeways, boat houses, underpasses, storage sheds, barns, sports arenas, convention centers, parking garages, car washes and more.

Indoor only, needs to be in an enclosed or semi-enclosed environment like a warehouse, airplane hangar, overhang, or canopy.  Operates on AC power only.

4 internal speakers cover 6,400 square feet (40' from each speaker).

From each speaker the sound wave travels vertically at a 20 degree angle (max 5' height) and Horizontal it travels at a 90 degree angle (max 40' width).

Needs to be mounted at the same level where the birds sit; creates a two-dimensional harassment zone.
