High Tech Pet Microsonic 2 Plus, Standard Ultrasonic Collar

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 Type 2430 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.
