• Reliable Material: This deer warning whistle is made of high-quality ABS plastic, which is resistant to high and low temperatures and can function even in extreme weather conditions. People or pets inside the car are not affected and cannot hear ultrasonic sounds.
• Avoid collision: Ultrasonic whistles emit sound waves, while wind whistles produce sound through wind force. The two types of whistles work together to emit warning sounds. It can prevent deer, antelopes, and kangaroos from crossing the road and entering the path of vehicles, effectively avoiding collisions between animals and vehicles.
