Waterproof Collar Receivers: The craftsmanship that goes into every Perimeter® brand product is so good they offer the only battery replaceable waterproof collar receivers on the market. Perimeter® brand ComputerReceivers will continue to function without issue when completely submerged in water. Have a pool, pond or take your dog to the lake? This tough collar is up to the task.

Closer Spacing Between Contact Posts: Small dogs and cats have smaller necks. It is common for Invisible Fence brand R21 posts to be spaced too far apart, causing skin irritation and poor contact. Using Invisible Fence "cat post" attachments is a hassle and can sometimes irritate skin even more. Perimeter® brand pet fence collars have posts which are spaced 7/16" closer together, providing a better fit and significantly decreasing the possibility of pressure sores or skin irritation. Safer and more comfortable for all pets, especially little ones.

Tough Polycarbonate Collar Receiver: Polycarbonate plastic is a lightweight, high performance plastic which 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 such as external jet aircraft parts, the space shuttle and many military applications. Why trust the safety of your dog to anything less?

Seamless Warning Tone (Anti-Linger): Perimeter® brand ComputerReceivers avoid excessive battery drain from those dogs smart enough to sit in the warning area until the battery is dead. Perimeter® software seamlessly moves your dog from a warning tone to a very low level of correction 1 second after entering the warning tone area to avoid premature battery drain as well as to help promote the seriousness of their boundary. Allowing your dog to spend excessive amounts of time in the warning tone area 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, resulting in shorter battery life.
