The Perimeter Technologies ComputerReceiverTM is designed for use with the current model Invisible Fence R21 electric dog fence system. This collar is fully compatible and significantly cheaper than replacement Invisible Fence collars.

NOTE: This collar is NOT compatible with Invisible Fence 800 series systems.

The collar is waterproof and lightweight (the receiver weighs a touch over one ounce). The collar uses the Perimeter Technologies Comfort Contact rubber tipped prongs.

The collar uses the Perimeter Technologies battery (PTPRB-003) which is a little cheaper than the original Invisible Fence battery, costing $9.50 and having a similar battery life.

The collar is available in both 7k and 10k frequency models. You will need to check your Invisible Fence Control box to see which type of system you have and select the appropriate collar.
