Ultrasonic Bark Deterrent for Indoor Training

The DNBeffulgent SD-02BU uses three ultrasonic emitters to discourage unwanted barking in a humane way. It is designed for indoor use with dogs and operates on an included lithium-polymer battery. The light blue unit measures 5.4102 by 10.4902 by 14.4018 centimetres and weighs 0.209 kilograms. Adults aged 18 years and older should handle the device.

Replaces Shouting or Collar Corrections

This deterrent replaces the need for verbal commands or physical collar corrections when a dog barks excessively indoors. The ultrasonic sound interrupts the behaviour without causing pain, making the jump worthwhile for owners who want a sound-based training aid. It is not suited for outdoor environments or for households that need a multi-dog system with separate zones.

Simple Placement with Battery Care

Setup requires placing the unit in the target room and turning it on, since the battery arrives already installed. The sealed lithium-polymer cell cannot be swapped by the user, so the whole device must be replaced when the charge no longer holds. No wiring or mounting hardware is involved.

Questions about this item

How much wall or shelf space does the 14.4018 cm tall light-blue unit need?

Allow at least 14.4018 cm of vertical clearance and a footprint of 5.4102 cm by 10.4902 cm; the device weighs 0.209 kg so most adhesive strips or a single screw will hold it securely.

What is the correct way to mount the SD-02BU and which step is often missed?

Fix the unit at dog-ear height pointing toward the barking zone, then press the power button once to activate the three ultrasonic emitters — forgetting that press leaves the device in standby.

When will the built-in lithium-polymer cell need attention?

The sealed 5 Wh battery is not user-replaceable; after several hundred charge cycles the runtime will shorten, at which point the whole deterrent should be replaced.
