Digital circuitry in this state of the art design provides a strong signal and maintains accuracy over all temperature ranges. It is extra rugged so it won't get damaged during your dog's "ruffhousing".

With a robust， fully enclosed ultrasonic transducer speaker， it is immersible to 6ft.， and although we don't recommend immersing your dog in 6 ft. of water without scuba gear， the collar will stay high and dry! The MS-5 uses our specially designed B-3V1A battery which lasts about 3 months and prevents damage to the circuitry if the battery is installed incorrectly.

The MS-5 Pet Collar encompasses the Ultrasonic family of our exclusive Pet Activated World System (PAWS). It powers ALL Power Pet Door models， the Sound Barrier Wireless Sonic Indoor Area Fence， and the Yard Barrier Outdoor Sonic Area Fence.
