High Tech Pet MS-2A Microsonic Extra Rugged Waterproof Ultrasonic Collar

A special version of the the best selling MS-2 ultrasonic collar with a fully enclosed ultrasonic speaker. The new MS-2A is more water-resistant and rugged. It's perfect for the pet who likes to do some serious "ruff-housing". While it isn't recommended you let your pooch take it for a dip in the pool, the new MS-2A 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. The enclosed transducer (speaker) is much more robust than conventional open air transducers and will stand up to far more abuse from your savage beast. It is highly recommended that you upgrade to the new MS-2A if you have a very active pet who likes to get wet.
This tiny, lightweight collar weighs only about one ounce and is appropriate for all cats and dogs. It emits a directional ultrasonic code that automatically operates the indoor Sound Barrier, outdoor Yard Barrier sonic fence systems, and the amazing Power Pet fully automatic Pet Doors. One size fits comfortably on any size pet from kitten to St. Bernard. This ultrasonic transmitter also repels fleas. Strange as it sounds, the MS-2 emits the same powerful ultrasound as the very popular electronic flea repelling collars. So, repel fleas while you automate your pets' environment with the MS-2 pet collar. Includes one long life Lithium battery. Extra Lithium batteries available.
NOTE: This is an ultrasonic transmitter only, not a radio receiver or shock collar. If you need an extra transceiver collar for the Humane Contain System, order the RX-10.
