The UnderGround – Perimeter Technologies Ultra – No Wire only consists of the Perimeter Ultra Comfort Contact fence. This pet fence contains a difference you can feel for yourself. The fence keeps your pet safely in the yard. The collar uses cushioned contact points for a more comfortable collar. The Comfort Cushion Contacts uses soft rubber instead of hard steel in the collars. Veterinarians prefer the softness of the Comfort Contacts to help reduce the incidence of skin irritations. The flags work as visual aids for you and your dog to mark the fence boundaries. Remove the flags once the boundary areas are known. The fence splices connect two wires together.
The Perimeter Ultra Comfort Contact fence gives you the flexibility of changing the frequency being used. This avoids problems with the same frequency being used by you and a neighbor. With the Perimeter Ultra Comfort Contact fence you also have the ability to change stimulation settings. You can set up a custom range of correction options. This allows you to use options to fit your dog’s specific temperament. In fact, program each dog’s collar to provide only the necessary correction level to be effective.
The UnderGround – Perimeter Technologies Ultra – No Wire does not contain wire or flags. Dog fence wire/Pet fence wire is required to use this underground fence system. The UnderGround – Perimeter Technologies Ultra – No Wire should be purchased only by customers who:
- Already have wire installed in their yard, or
- Will obtain their own wire

Additional UnderGround – Perimeter Technologies Ultra – No Wire Information:
Perimeter® products designed and manufactured in the USA. Perimeter® Technologies is proud of their heritage as some of the original dog fence industry founders. Also proud of their future as a domestic manufacturer of premium dog fence safety products.
Patented Temp Check:
Only Perimeter® brand dog fence systems feature internal circuitry which provides stable operation over a broad range of temperatures. The signal field width in competitive brands can vary up to 100% between 40 to 90 degrees Fahrenheit. What does that mean? A Perimeter® brand dog fence set to have a field width of 8 feet will have a maximum variation in field width of 5% (less than 5”). A competitive system can have a variance of up to 100% either way for cold or warm environments. In other words, other systems could potentially have no signal field in cold environments. Or twice the field width in hot environments. This means the dog fence system may not be able to contain your dog. This could be due to limited field width. Or the fence system could correct your dog inside the safety of your home.
Patented Wire Check:
Only Perimeter® brand dog fence systems features a state of the art transmitter. This provides the ability to monitor wire input and output automatically. This allows the system to perform even with damage to the boundary wire. (No System can function with the wire completely broken.) The field width will remain constant on both sides of a damaged boundary wire. This is due to the power output management built into every Perimeter® brand dog fence. In the event of a catastrophic event resulting in total wire failure the system gives a constant audible indication of the breach.
Patented Battery Check:
Only Perimeter® brand dog fence systems monitor the status of the battery every two hours. This ensures you know when your dog fence needs a new battery. Other brands offer low battery indication. However they only let you know when the battery dips below a certain output level. The chemical composition of a battery fluctuates over a variety of different operating conditions. This could potentially signal a false low battery indication. Perimeter® brand systems save you time and money. It requires 3 consecutive low battery triggers to set off the low battery indication.
Polycarbonate Collar Receivers:
Polycarbonate plastic is a lightweight, high performance plastic. It possesses a unique balance of toughness and dimensional stability. Perimeter® brand dog fence collars use polycarbonate plastic to make them resistant to damage from dog chews. Polycarbonate is frequently used in situations where safety and performance are a must. Examples are external jet aircraft parts, the space shuttle and many military applications. Why trust the safety of your dog to anything less?
Waterproof Collar Receivers:
The Perimeter® brand dog fence offers the only battery replaceable waterproof collar receiver on the market. This is due to craftsmanship that goes into every Perimeter® brand dog fence. Perimeter® brand receivers continues to function without issue when completely submerged in water. Have a pool, pond or take your dog to the lake? Take your Perimeter® dog fence with you.
Progressive Correction w/Run Through Prevention:
Perimeter® brand dog fence systems offer progressive correction. This measures time and distance from the collar to the boundary wire. This feature allows the computer collar to know not only how far away it is from the boundary wire but how fast the collar, and subsequently the dog, is traveling. In a fraction of a second the collar makes the necessary adjustments in correction intensity. This ensures your dog stays safe at home.
Seamless Warning Tone (Anti-Linger):
Perimeter® brand dog fence systems avoid excessive battery drain. This can happen with dogs smart enough to sit in the warning area until the receiver battery is dead. Perimeter® software moves your dog from a warning tone to a low level of correction 1 second after entering the warning tone area. This avoids premature battery drain as well as to help promote the seriousness of their boundary. You should not allowing your dog to spend excessive amounts of time in the warning tone area. This will condition them to not take the fence as seriously as they should. Additional time in the warning area will promote testing the fence more frequently causing shorter battery life.
Custom Correction Programming:
Five programming options are available for each dog on the system. You may have a small timid dog which requires far less correction than your other large “bull-headed” dog. Perimeter® brand dog fence systems give you the ability to custom program each receiver to match the dog’s temperament. Should your dog fence administer the same correction to your timid dog just to keep a stronger willed dog in the yard? That doesn’t sound safe or humane?
Replaceable Lithium Ion Battery Technology:
Lithium Ion technology offers three times the gravimetric density of nickel metal hydride technology. This provides lighter batteries with increased run times. Replacing batteries provides the ability to instantly renew the collars power supply should you forget to recharge it. It also provides a consistent duration for battery life as opposed to the diminishing lifespan of a rechargeable cell.
Digital Frequency Encoding:
Eliminates stray signal interference from neighboring dog fence systems as well as other signal generating devices. In addition to the encoding Perimeter® brand pet fences operates on a 7 KHz frequency. This provides less frequency interference than other dog fence systems operating on more widely used bands.
Most Humane Contact Points:
Comfort Contacts™ by Perimeter® offer the most comfortable solution to create contact with your dog. Conductive metal infused rubber provides significant protection against pressure necrosis. This is a condition happens when one of two things occur. A dog either has a negative skin reaction to metal touching their skin. Or the collar is left on for a prolonged period of time. Soft conductive rubber contacts allow the contact to remain constant keeping your dog safe at home with utmost is comfort.
Omni Directional Signal Detection:
Many containment systems only detect signals coming in from one or two directions. This is due to using one or two internal antennas. Perimeter® brand dog fence systems uses three internal antennas. This detects the boundary signal on three separate planes to provide the most effective signal detection available.
Auto Safety Shut-off:
Perimeter® brand dog fence systems feature a built in safety mechanism. It automatically shuts off after 20 seconds of correction. This safety features ensures no unnecessary correction for dogs. This includes dogs who may be in the boundary field and panic. Also for those crazy kids who think it might be fun to lay down in the containment field. Should this happen they will only have to endure 20 seconds of discomfort; hopefully enough for them to learn their lesson. The system will automatically reset following its removal from the field.
