【Stop Wild Dog Barking】: When a wild dog barks around, the bark will be detected by the barking control device's built-in microphone and emit a high pitched ultrasonic sound (inaudible to the human ear), thus stopping the wild dog from barking.
【50 Feet Effective Range of Action】: Anti Barking Device can be used effectively up to 50 feet, please make sure the device is hung below 5 feet and keep the device facing the dog as much as possible to get the best results.
【4 Different Levels】: one test gear (for testing whether the microphone and speaker are working properly) and three different sensitivity levels, respectively. Divided into Low Sensitivity (15 feet distance), Medium Sensitivity (30 feet distance) and High Sensitivity (50 feet distance). If the dog does not respond to the current gear, please raise the gear of the device.
【Outdoor Companion】: When you are riding, hiking or jogging outdoors, you can carry this barking control device with you. Its mini size will not bring you any burden, but it can effectively prevent the outdoor wild dogs from harassing you.
【Absolute Safety】: The principle of Bark Control Device is to deter dogs by sending out ultrasonic waves, thus achieving the effect of stopping barking, but humans cannot hear ultrasonic waves.
