SOUND BARRIER ^TM and YARD BARRER ^TM Sonic Fences Keep Pets OUT and OFF!

What's the difference between an Electronic Fence and a Sonic Fence? Simply put, Electronic Fences keep your pet IN. Sonic fences keep your pet OUT by emitting a loud blast of audible sound to startle your pet and make him scat!

Here's How They Work: Our Sound Barrier™ and Yard Barrier™ systems use the MS-4 or MS-5 (upgraded) ultrasonic collar and an ultrasonic receiver unit that emits a loud sonic blast when it detects the collar. This creates an invisible barrier protecting the off-limits area. Sonic fences are completely wireless and do not require a buried wire or any complicated installation effort. Just put the collar on your pet, put the receiver in the off-limits area and you're done!

PART OF OUR EXLUSIVE PAWS SYSTEM!
The MS-4 and MS-5 collars are part of our Pet Activated World System (PAWS)family of products. These same collars operate the Sound Barrier™ Indoor Sonic Fence, Yard Barrier™ Outdoor Sonic Fence and all our Power Pet™ Fully Automatic Pet doors. All these products may also be operated by the Universal RX-10 containment collar to create your own custom Electronic Radio Fence and Sonic Fence, and Power Pet Door combination system.
