The High Tech Pet Radio Mat gives you a complete, versatile pet area restriction training system in one convenient product. It is a great alternative to Scat Pad because it corrects only the behavior of the pets wearing the radio collar, not people. The Radio Mat uses three modes of operation including Shock Only, Sound Only, or Sound and Shock Together. You choose the appropriate training method for your pet. When your pet steps on the Radio Mat, it sends out a radio signal to your pet's special radio receiver collar. Depending on what you have programmed, the collar then will either emit a harmless but unpleasant shock, use a sound blast to startle the pet or in the case of stubborn pets use both the shock and sound stimulus to make them scat. Add as many extra transmitter pads as you like to control multiple areas. Add as many transmitter collars as you like to control multiple pets. The Transmitter Pad also works with the Humane Contain™ RX-10 Rechargeable Multi-Function Collar and RC-8 Ultra Collars. If the collar says "Humane Contain" it will work with the Radio Mat™. Includes radio collar with battery and 12"W x 60"L mat. Mat requires a 9-Volt battery (not included). Ship directly from manufacturer.
