Uses high-frequency ultrasonic sound that projects in a cone shape 150 degrees in front of the speaker to disrupt barking, works on most dogs within hearing range- no bark collar needed!
Durable and weatherproof, for outdoor use only.
Uses standard 9-volt batteries (not included) with two-color LED for good/low-battery indication.
