Sound Pressure Level: 120dB(A.S.) Operating Base Frequency: 4.8 ± 0.5 kHz WV Ultrasonic Wave: 18,000 to 21,000 Hz Wave Carrying Length: 1,600 Ft. ± Effective Range: 700 Ft. Operating Voltage Range: 8-16 VDC Current Consumption: 10mA (max.) at 12 VDC The Hornet uses the LATEST MILITARY TECHNOLOGY to clear your way. The Hornet is your best protection against costly and deadly animal related accidents. Using the latest military technology from the field of high pitched, directional sonic bombardment, the Hornet's precision turned sonic generator alerts deer and other animals of your approach well before they can see or hear your vehicle. Proprietary wave variance tuning enables the sonic impulse to carry long distances. The Hornet is endorsed by major insurance companies and is used by police and emergency vehicles nationwide with millions of proven road miles. Proven effective at any speed, the Hornet is electronically powered and does not rely on wind or air flow. The Hornet Deer Avoidance Device is a precision tuned sonic generator which produces a high pitched, directional sonic wave. When this wave is reflected from the road surface of a moving vehicle, a virtual sonic echo effect is produced. This sonic wave has proven its ability to alert deer and most other animals to approaching vehicles with sufficient warning to avoid costly accidents. The use of the Hornet, along with driver awareness, has been proven to reduce the risk of animal/vehicle collision by more than 70%. The electronically produced sonic wave is effective at any vehicle speed. The Hornet Deer Avoidance Device is your best protection from vehicle damage and deadly animal related accidents.
