Electronic Deer Alert

We don't have to tell you how costly and dangerous hitting a large animal can be. Don't become one of the 650,000 drivers to hit a deer this year. Thousands of motorists have installed wind-powered, ultrasonic "whistles." The problem is that these devices—even if kept clear of insect debris—can't produce sound in the range most effective against deer and elk. Our Electronic Deer Alert's two wires install easily to your car's battery, sensing current changes to turn itself on when your engine is running. The unit produces both ultrasonic frequencies (heard by cats and dogs) and—when in the "active mode"— audible sweeping whistles to warn away larger animals.
