The PetSafe
Basic In-Ground Fence
The PetSafe Radio
Fence Pet Containment System is the Best, most Versatile Pet Fence ever made!
PetSafe is the leader in Underground Fences. Their underground dog fences carry
a LifeTime Warranty.
How Underground Fencing Works: The Transmitter plugs into a standard
outlet and emits a radio signal that travels along an underground wire. The
lightweight receiver worn on your pet's collar picks up the radio signal and
alerts him as he nears the underground boundary that you have customized for
your yard. If he continues toward the boundary, he will receive a mild
correction, similar to a static shock. 
The maintenance free design and ease of installation offers tremendous savings
compared to conventional fencing and other systems of this type. Petsafe fences
use the Asics Chip, the only microprocessor designed specifically for the
dog fencing industry. This microprocessor has 3,000 filters to eliminate the
possibility of interference. These systems use inexpensive commonly available
batteries or long life battery modules and are the only UL Classified and FCC
Certified systems on the market. The transmitter, receiver, and power adapter
are UL Approved. In addition, the Deluxe Ultralight Receiver is the smallest and
lightest receiver available, 1.4 oz. including batteries.
