Haijunnm Dog Bark Deterrent Device – 6-in-1 Ultrasonic Trainer, 50 ft Range, LCD, Type-C

Overview

The Haijunnm 6-in-1 bark deterrent device combines dual-frequency ultrasonic technology with a responsive LED visual cue to support humane, non-contact training. With fixed 25kHz and adjustable 20-30kHz sweeping modes, it adapts to your dog’s sensitivity, offering a calm, consistent training experience without shocks or pain.

Smart, visible control at a glance

Designed for precision, the built-in LCD screen shows battery level and the current frequency mode in real time. This lets you train with confidence, monitoring activations and adjusting settings as needed to match your dog’s responses.

• Real-time battery indicators help you plan training sessions
• Mode visibility reduces guesswork during practice

Safe and humane training features

The device relies on sound and light cues, avoiding any physical shock. The LED provides two modes: a steady beacon for illumination and a strobe cue during training. The steady mode also functions as a high-intensity flashlight for dim environments.

• Two LED modes support day or night training
• Light cues act as visual reinforcement during sessions

Powerful range, precise delivery

Equipped with three sonic emitters, the device projects a focused ultrasonic signal up to 50 feet toward the dog. This helps interrupt barking reliably whether your dog is nearby or across a room, and it can be used to deter other dogs in outdoor spaces as well.

• Effective up to 50 feet with a concentrated ultrasonic beam
• Triple emitters ensure coverage across typical training areas

What it can help with

Use brief 1–3 second activations to guide your dog toward calmer behavior. The system is designed for 6 months to 8 years old dogs without hearing impairments and is not recommended for dogs with epilepsy or seizures.

• Addresses barking, digging, scratching, and similar nuisances
• Supports calm responses when used consistently

Portable, ready when you are

Weighing just 110 g with a compact 4.3 × 1.7 × 1.7 inch form, it travels easily. A lightweight anti-loss wrist strap helps keep it secure during walks or outdoor adventures.

• Lightweight and compact for home or travel
• Wrist strap reduces the chance of misplacing the device

Power and longevity

Charge quickly via Type-C in about 2 hours. Expect up to 30 days of regular use or 180 days on standby, making it a reliable training companion whether at home or on the go.

• Type-C fast charging for quick readiness
• Long-lasting power supports extended training sessions
