Professional Ultrasonic and Light Dog Repeller Anti Barking Deterrent Dual-Action Bright Pets

Professional Ultrasonic and Light Dog Repeller Anti Barking Deterrent Dual-action ultrasonic and Bright Light Pets Trainer The primary dog repellent employs directional high-frequency ultrasound (fixed-frequency and frequency-scanning to prevent adaptation) + intense strobe lighting (visual disruption) + low-power circuit design to achieve safe, efficient canine deterrence. It operates as a ‘conditioned reflex’ protective tool, leveraging instinctive animal responses. This repeller achieves its core function of deterring dogs through the synergistic action of ultrasonic technology and acoustic-visual stimuli. Its operating principle is based on the unique auditory and perceptual characteristics of canines, specifically divided into the following modules:  1. Ultrasonic Repellent Principle Canine Auditory Sensitivity Range: Dogs possess an auditory range of approximately 40Hz–60kHz (far exceeding the human range of 20Hz–20kHz), exhibiting particular sensitivity to high-frequency ultrasonic waves (above 20kHz). The 20kHz–30kHz ultrasonic waves emitted by the repeller stimulate the canine auditory system, inducing discomfort or alertness and prompting voluntary retreat from the sound source.  2. Frequency-Sweeping Technology Prevents Adaptation: The device employs an automatic frequency-sweeping mode, continuously varying ultrasonic frequencies within the preset range (e.g., switching 1-2 times per second). This prevents dogs from developing ‘immunity’ through prolonged exposure to a single frequency, enhancing the repellent's long-term effectiveness.  3. Single/Dual Ultrasonic Transducer Design: Single and dual ultrasonic transducers convert electrical signals into high-frequency mechanical vibrations, directing focused ultrasonic beams to ensure concentrated energy and extended range (effectively covering 5-10 metres).  4. High-Frequency Visual Distraction: The device's built-in LED synchronously flashes at high frequency (e.g., 3-5 times per second) during ultrasonic emission. Exploiting dogs' sensitivity to rapidly moving light sources (particularly at night), this visual disruption reinforces the deterrent effect.  Functional Description: 1. Fixed-frequency mode: Press the fixed-frequency button to activate. the front F5 indicator remains lit. Release the button to deactivate. During operation, the indicator displays a steady green light. 2. Pressing the Sweep Frequency button initiates frequency sweeping, causing the front F5 LED to flash rapidly. during operation, the indicator displays a steady green light. Releasing the Sweep Frequency switch halts the sweeping function. 3. During charging, the charging indicator displays a red light. upon full charge, it switches to green. When battery level is low, the red light flashes as a warning.  Precautions: 1. Avoid prolonged use in high-temperature, humid, or enclosed environments. 2. Do not direct the ultrasonic emitter towards human or pet eyes. 3. Regularly clean the ultrasonic emitter aperture to ensure no obstructions affect performance. 4. Certain canine breeds (e.g., hearing-impaired dogs, puppies) may exhibit reduced responsiveness to the device. supplementary protective measures may be required. 5. Children must operate the device under adult supervision.
