• Reported car-deer collisions account for half a million to one million accidents per year. An estimated 15,000 people are injured and over a hundred are killed in vehicle collisions with animals each year. • Every year, deer-vehicle collisions account for over $125 million in medical and hospital costs, and over $900 million in vehicle repair costs. The average cost to repair a vehicle from a deer collision is between $1,500 and $2,000. • The deer population has doubled to 25 million in the last 10 years, and collisions are on the rise. • Deer Alert's unique "transonic pulse" emits both audible and ultrasonic sound to alert a wide range of animals. The sonic tones alert all animals and the ultrasonic tones alert smaller animals such as pets. • Deer Alert helps prevent injuries and costly damage from vehicle collisions with animals. • Deer Alert works from up to 2,000 feet away. • Unlike wind-activated devices, Deer Alert helps prevent vehicle collisions with animals at any speed. You can turn Deer Alert ON or OFF at any time by switching the ignition on and off twice or flashing the headlights twice (model # 27509) or by using the included dashmount switch (model # 27510). • Deer Alert will not clog with dirt, debris, or grime which make many other animal-warning devices inoperable. Deer Alert is completely waterproof.
