The whistles can help minimize the risk of deer collision by warning deer of stopping on the roadside in advance. Package Content: You will receive 2 ultrasonic whistles, which feature an ultra-small body, dual structure and two wave frequencies. This is a humane design to drive away animals.

And the whistle itself is a perfect ideal for your driving outdoors. Material: Made of sturdy ABS plastic, outdoor high temperature resistant and sub-zero temperature resistant.
