High Tech Pet Ultrasonic Collar MS-4

The totally new “digital” MS-4 is our enhanced replacement for our most popular MS- 2A heavy duty Microsonic Collar. Using digital circuitry this state of the art design provides a stronger signal and maintains better accuracy over all temperature ranges. It also uses our specially designed B3V1A battery which lasts about 5 months and prevents damage to the circuitry if the battery is accidentally installed incorrectly. With a fully enclosed ultrasonic speaker the MS-4 is more water-resistant and rugged that the original MS-2. It's perfect for the pet who likes to do some serious "ruffhousing". While we don't recommend you let your pooch take it for a dip in the pool, our new MS-4 is fully immersible for short periods of time and will continue to work even when wet. It will stand up to heavy rain showers and is perfect for dogs who love to play in the snow.
