Humane and effective ultrasonic deterrent: Uses advanced ultrasound in the 25-40 kHz range to deter stray dogs safely, without harming pets, people, or the environment. Ideal for gardens, farms, and yards. All-weather durability: IP65 waterproof; resists rain, snow and extreme temperatures to provide year-round protection in any outdoor setting. Fully automated operation: A motion-activated sensor detects animal movement and triggers ultrasound immediately; no manual intervention required. Install with batteries and let it run. Quiet and neighbor-friendly: Ultrasonic frequencies are inaudible to humans; operates quietly without disturbing your household or neighbors. Practical use scenarios: - Shield garden beds, poultry runs, and orchard borders from wandering dogs or wildlife. - Protect driveways, patios, barns, and other outdoor spaces on farms or rural properties. - Use in remote sheds, paddocks, or outdoor storage areas where power outlets are not available.
