Ultrasonic dog repellers utilize a 25000Hz frequency, inaudible to the human ear, to emit a momentarily loud, explosive sound that stimulates the dog's hearing and nervous system, frightening it and thus repelling it.
1. Ultrasonic dog repellers emit strong ultrasonic waves (ultrasound). When used properly, only animals can hear this sound; humans cannot.
2. The energy of an ultrasonic dog repeller is approximately 125dB/30cm, which can cause discomfort and unbearable disturbance to animals. This piercing sound intensifies as the animal approaches.
3. Operation is easy. Simply point the ultrasonic speaker at the approaching animal and press the switch button continuously for 2-3 seconds to let it know the source of the uncomfortable sound wave.
4. Because the output sound wave decreases when deviating from its target, changing the direction of the dog repeller and continuously pointing it at the approaching animal will enhance the effect.
5. It is an ideal choice for outdoor enthusiasts, cyclists, and car travelers who wish to avoid being bothered by dogs.
