Once powered on, its intelligent microphone detects barking up to 75 feet away and instantly emits a safe ultrasonic tone (inaudible to humans, unpleasant to dogs). Over time, your dog learns to associate the sound with silence – no shocks, no sprays, no collars. Key Features Fully Automatic Operation: Simply turn it on and place it where your dog barks. No remote control, no phone app – it works 24/7 by itself. Dual High-Power Ultrasonic Transmitters: Two large‑area emitters deliver strong, consistent coverage for large yards, kennels, or multi‑dog households. 3 Adjustable Sensitivity Ranges: 25 ft, 50 ft, or 75 ft – match the detection zone to your space. Higher range = more sensitivity. 2 Ultrasonic Modes: Fixed Frequency: Constant tone for stubborn barkers. Variable Frequency: Intermittent tones to prevent habituation. IP65 Weather‑Resistant: Fully dust‑tight and protected against low‑pressure water jets – safe for covered patios, garages, or outdoor use. 2000mAh Rechargeable Battery: Long standby time with USB fast charging (cable included).
