Ultrasonic Bark Deterrent with 50ft Range

The DNBeffulgent U20 uses two dual high-power ultrasonic emitters to create a 50ft bark shield. It delivers 200% higher sound pressure than standard models and operates without physical contact. The device offers a humane alternative to bark collars for training dogs of various sizes.

Five Modes for Behaviour Correction

The unit includes Gentle LF Ultrasonic at 25kHz for small breeds and Smart VF Scanning between 20kHz and 35kHz to prevent adaptation. Enhanced HF+Strobe LED at 30kHz adds visual cues for stubborn barking. Beep Deterrence interrupts aggression and Night Light Mode provides pathway illumination. Buyers who need a remote-controlled collar or a citronella spray system should look at other product types.

50ft Effective Range Decides Suitability

The ultrasonic signal reaches up to 50ft to cover indoor rooms and outdoor yards. This distance determines whether the device can address barking triggered by doorbells or fence-line disturbances. Consistent use over 5-7 days significantly reduces excessive barking within this zone.

Questions about this item

Does the pink U20 come with everything needed to start training right away?

The device itself is supplied in pink; no batteries, cables or accessories are mentioned in the specifications.

Which ultrasonic frequency should I pick for a small breed versus a large breed?

Use the 25 kHz Gentle LF mode for small breeds and the 30 kHz Enhanced HF mode for large breeds; the 20–35 kHz Smart VF Scanning mode covers both.

How does the 50 ft range perform when the dog is behind a fence or window?

The dual emitters create a 50 ft ultrasonic shield that penetrates fences and windows to stop barking triggered by doorbells or neighbour dogs.
