Features:
Usually, one ultrasonic whistle (a whistle with hole in the tail) is matched with one wind whistle (a closed-hole whistle) to drive deer away in better results.
The deer whistles can attract animals' attention, when your car is moving at 30 mph or faster, the whistles can automatically emit a high-pitched noise and encourage deer to quickly move out off.
