Compatible Collars & Straps

Invisible Fence® Brand R21 Computer Collars are extremely expensive and not as feature-rich as the compatible Perimeter Technologies dog fence collar. Invisible Fence® Brand dog fence systems use proprietary collars and batteries, which they sell at very high prices. Many people invest in an Invisible Fence® Brand dog fence system without realizing how quickly the cost of the proprietary components will add up. 

Perimeter Technologies has developed a dog fence collar that is 100% compatible with Invisible Fence® Brand 700 Series (and older) Dog Fences. The Perimeter Technologies collar is smaller and lighter, completely waterproof, and features comfort contact points and progressive correction. Most importantly, this Invisible Fence® Compatible Collar is available at a fraction of the price of the proprietary computer collars. The collar is available in either 7K or 10K frequency to match the frequency of your dog fence. 

Replacement Invisible Fence® nylon collar straps are also available. Please see the product pages for details on collar strap compatibility.

Unfortunately we don't carry any compatible collars for that Invisible fence system. Maybe you'd be interested in trying our Invisible Fence Trade-In Program
