SportDOG NoBark 10R SBC-10r The NoBark 10R 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 10R offers 10 levels of correction. As a built-in safety feature, if your dog barks 15 or more times in 50 seconds in any mode, the unit will automatically shut off for 3 minutes. Fits neck sizes 6-28 inches.
