GRAD А-16 bird repeller is a bio-acoustical device designed to scare pest birds away. Pest birds are destructive to agriculture and our device can help keep them away from your crops, vineyards, gardens, etc.  It can also be used in urban areas, where large bird flocks, e.g. crows or doves, are a source of loud noise and destruction to exterior decorations and roofing.

• The method is humane and eco-friendly!

• High level of efficiency is proven by agricultural workers.
• Large coverage area (up to 7000 m2 or 75,000 sq. ft.) allows to keep large outdoor areas free of birds such as yards, agricultural fields and industrial areas.
• Large variety of bird sounds recordings (16 pcs) allows to control birds in any given area or repel only some of the species.
• Customizeable mode settings (Day/Night, adjustable volume) allows to diversify the bird repeller operation process.
• Autonomous car battery operation and protection from atmospheric precipitations allow the repeller to operate properly in the open field environment.
• Random mode option keeps birds from adapting to repetitive sounds.
• English manual included.

GRAD А-16 bird repeller’s working principle is based on the natural response of birds to distress cries and predator calls. This is a bio acoustical principle, i.e. GRAD А-16 bird repeller produces above-mentioned sounds to scare the pest birds away.

Playing these sounds is not harmful to birds but it triggers their instinctive fear and makes them leave the guarded facility immediately. It’s important because, unlike destruction, the offered method of control doesn’t have devastating effects on bird populations. It’s humane and eco-friendly. Among other positive things, birds sanitize the habitat from insect pests during the nesting season. Nevertheless, it’s crucial to control birds. 
 

• Birds are destructive to property, equipment and merchandise.
• Governmental organizations can cite, fine or shut down companies due to unsolved bird problems and violations of laws and regulations.

• Bird mortality is unsightly and dangerous.
• Birds and their droppings create unsanitary conditions and can cause over 60 transmittable diseases.
• Cleaning surfaces and equipment from droppings is a labor-consuming, time and money wasting process.

Moreover, experience has proven that the bio-acoustical method is much more effective than repelling by whistles, clappers or gunshots.

GRAD А-16 bird repeller runs under the microcontroller with built-in software. Power is supplied from a 12V DC voltage outlet source.
