High Tech Pet SB-1 Sound Barrier Indoor Sonic Fence with MS-4

Keep your dog or cat off the couch, away from the kitchen table or out of an entire room with our new SOUND BARRIER, indoor electronic fence. The Sound Barrier is an electronic pet containment system for dogs AND cats that uses audible SOUND, not shock to keep your pet out of restricted areas. The Sound Barrier's Receiver unit may be placed on table tops, by doors, bed, couch, trash can or anywhere that is "off limits" to pets. The ightweight electronic pet collar sends an ultrasonic signal that triggers a loud sonic blast at the receiver unit when the pet approaches. Dogs and cats are quickly and easily trained to Stay Away!
