1. The Dazer III ultrasonic device is a repellent for aggressive dogs, featuring an upgraded 3.0 version with dual ultrasonic speakers. 2.

The approximate range is around 10 meters, with a maximum effective range of 6 meters at 100% intensity. 3. Now, you can jog, run, or bike along roads or mountain trails without fear of dogs approaching. When the ultrasonic button is pressed, the device vibrates to confirm activation. 4.

Using the Dazer III is simple—just press one of the two buttons and aim at the dog. Upon detecting the ultrasonic waves, the dog will stop and avoid approaching to prevent contact. 6. The Dazer III offers three modes: **Ultrasound**: Choose from three frequency types— *Stable*: 25 kHz waves for prevention. *Irregular*: Waves fluctuating between 20–25 kHz for repelling. *Wellig*: Sharptipped waves for dog training. **Ultrasound Flashlight**: Combine ultrasonic frequencies with a flashing light. **Annoying Sounds**: Emits irritating noises to deter dogs.
