713 Sonic Deterrent for Dog Training

The DNBeffulgent 713 Sonic Deterrent is a handheld ultrasonic device designed to stop unwanted barking and correct behaviour in dogs. It emits sound waves at 23, 25 or 27 kHz that are inaudible to humans but sensitive to canine hearing. The tool combines a bark deterrent, a training whistle and a clicker function into one blue unit. It is aimed at owners who want a painless, remote way to manage their dog's actions.

Replaces Separate Collars, Whistles and Clickers

This single device removes the need to buy and carry a separate bark collar, a dog whistle and a clicker for training sessions. The manufacturer states it can achieve results 300% faster than using those individual tools alone. The upgrade is worth it when you want one rechargeable unit with a 1000 mAh battery that lasts around 30 days per charge instead of managing multiple disposable-battery gadgets. A security lock prevents accidental activation while carrying it.

Ultrasonic Range Limited to 25 Feet Outdoors

The sonic output reaches a maximum of 25 ft, so the dog must be within that distance for the correction to register. Thick walls, heavy foliage or strong wind can reduce the effective range further. The unit relies on line-of-sight sound propagation and does not work through solid barriers. The 1 Wh lithium-ion cell is built into the housing and cannot be swapped in the field.
