DNBeffulgent XP31 Ultrasonic Dog Bark Deterrent 50ft Blue

Handheld ultrasonic bark deterrent

The DNBeffulgent XP31 is a handheld ultrasonic device designed to interrupt excessive barking in dogs of most breeds. It emits sound at two frequencies, a fixed 25kHz tone and a variable 20-30kHz pattern, to prevent animals from becoming accustomed to the signal. The unit features three synchronized ultrasonic heads for wider coverage and includes a safety lock to prevent accidental activation while carried.

Consistent output for repeated training sessions

The device maintains its ultrasonic output across multiple activations during a single walk or training period without a noticeable drop in intensity. The alternating frequency pattern is intended to sustain the dog's responsiveness over successive uses rather than losing effectiveness as the session continues. Its 50ft operational range remains stable whether used indoors or in open outdoor spaces.

Pocket-sized with a safety lock

The unit measures 5.6896 x 10.8966 x 15.1892 centimeters and fits easily in a pocket or bag for quick access. A dedicated safety lock button must be disengaged before the red activation button works, reducing the chance of unintended emission while moving. No complex setup is required; the device is ready to use straight from the package. It is not suited for situations requiring remote activation or automatic bark detection.
