The SBC-R-E is great for use in both single-dog situations or in a kennel setting with multiple dogs. Unlike anything before it, the SBC-R-E quickly determines your dog’s unique bark using Silent Partner technology and filters out all the rest so it’ll perform in either a single dog home or a kennel full of barkers. Either way, you’ll have the most superior bark detection. System includes: bark control unit, black collar strap, adaptor with charging cradle, long contact points and operating guide.
