Perimeter Technologies Underground Pet Fence - Safer designs you can see.

Safety is Perimeter’s utmost priority hence the development of its products was done by a group of competent engineers. The Perimeter® Engineering and Leadership team is an experienced group who are the creators of the first pet fence brand called Invisible Fence® in 1976. Their long term experience in providing safe pet fence systems will guarantee that your pet is in good hands. In fact, with Perimeter’s exclusive Comfort Contacts®, comfort is considered along with safety. This product cushions your pet’s neck with soft rubber thus helping them avoid skin irritation or injuries.

Perimeter Technologies Proudly Made in the USA

When it comes to the comfort and safety of your pet, seeing is believing. Perimeter's Comfort Contacts is the only one to proivde you with these advanced features.

• TEMP CHECK™ keeps the fence field stable and in the same location when outside temperatures change. Otherwise your fence boundary would move up to 100% when the temperature fluctuates between 30F and 90F degrees.

• WIRE CHECK™ automatically compensates for wire problems and adjusts the amount of signal power to ensure the fence boundary remains in a constant location (no system can continue to function if the boundary wire has been completely cut

• 12X BATTERY CHECK™ monitors the status of the training collar battery every two hours, eliminating false low battery indications saving you both time and money.

They came across a clever little terrier that discovered holding her head at a certain angle would cause the collar to not pick up the fence signal, giving her a ticket to freedom. And, certain danger.

So they developed their ingenious omni-directional antenna, designed to pick up the fence signal no matter what position the collar was in.

Not all pet fencing systems are created equal.

The pet fence difference you can feel for yourself! It’s one thing to make a product that keeps your pet safely in the yard, it’s another to thoughtfully design a fence with features that make it safer and more comfortable too.  Perimeter’s exclusive Comfort Contacts cushion your pet’s neck with soft rubber, unlike the hard steel probes used in other underground pet fence systems. Veterinarians prefer the softness of the Comfort Contacts to help reduce the incidence of skin irritations.
