The NoBark 18 uses a patented sensor system to provide the most reliable bark detection available. The unit delivers a static correction via the Contact Points only if it detects BOTH vibration from the vocal cords AND the sound of the bark. External noise or another dog¡s bark will not trigger a correction. The NoBark 18 provides six levels of correction in each of the Low, Medium, and High modes, for a total of 18 levels. In each mode, the correction starts at the lowest level and progresses to the next level (to a maximum of six levels) each time your dog barks within 30 seconds of the previous bark. If your dog does not bark again within 30 seconds, the correction will be reset to the lowest level in that mode. As a built-in safety feature, if your dog barks 15 or more times in 50 seconds, the unit will automatically shut off for three minutes.
