Electronic Bird Repeller -- models PRO 1 and PRO 2. Sonic repeller uses birds' own distress calls to create a "danger zone" -- it frightens infesting birds away for good.

Drives away crows, blackbirds, grackles, geese, pigeons, starlings, sparrows, gulls & woodpeckers.

And it's harmless. Although it attacks the birds with loud, terrorizing sounds, it doesn't harm them.

In extensive field tests, the electronic bird repeller has significantly reduced or completely eliminated bird infestations.

HOW IT WORKS: Electronic bird repeller features birds' distress cries on a microchip (supplied by a major American university). The pest birds perceive danger when they hear these sounds and become agitated and disoriented. Thinking their flock mates are in trouble, the pests on your property flee the area -- and never return.

SPECIES-SPECIFIC AND PROGRAMMABLE: Target your birds with a species-specific approach -- not scattershot. Each unit has eight sounds (bird distress sounds + predator calls). Adding the predator calls to your program increases the birds' perceived sense of danger. If you need to repel different birds in the future, simply reprogram your unit.

In addition to programming the selected birds, you can program volume, time-off periods (between sound blasts), and whether the bird sounds play in random or sequential order. These programming options make it virtually impossible for birds to get used to any one pattern.

EASY OPERATION: Use with standard 110-volt AC electricity (adapter included); 220-volt model available by special order (please contact us). Or purchase a 12-volt DC deep-cycle, marine-type battery with cables instead at your local hardware store.

HEAVY DUTY: Made of sturdy plastic. Directional speaker is in the front; controls in the back. Also includes a plastic rain cover with mounting tab, a plastic cover for the programmable switches, and complete instructions.

COVERAGE: Up to 1 acre at full volume in a long oval dispersion pattern.

Dimensions: 6" x 9" x 4"; weighs 4 pounds. 105-110dB at 1 meter; 3-5kHz; UL and CE listed. EPA Est. Made in USA.

Two models for your needs:

• PRO 1 targets pigeons, starlings, sparrows, gulls and woodpeckers.
• PRO 2 targets crows, blackbirds, grackles and geese.

CONSUMER NOTE: If you have a problem with birds from both groups, the manufacturer advises ordering the unit that handles the largest bird you are dealing with.
