Stop annoying barking of dogs within 40 feet. Super Bark Free™ emits a correction tone each time dogs bark. Sensitivity adjustment lets you control how loud the bark must be to trigger the tone. Frequency adjustment allows you to select either an ultrasonic sound (inaudible to humans) or a sound audible to both dogs and humans. Super Bark Free units are designed for outdoor use only and feature battery operation for use as a portable training tool. Bark selector allows the unit to be activated after 1-5 barks. Includes a cone to focus correction towards barking, a wall-mount bracket and an AC adapter.
