PT-Connect: Keep Your Compatible Fence
Replace a collar or add another dog with PT-Connect from Perimeter Technologies. Auto-Detect Technology identifies your compatible outdoor wired/in-ground Invisible Fence® brand system automatically, without needing your transmitter model or a 7K/10K collar selection. Choose rechargeable or replaceable-battery collar and programmer kits. Compatible with Boundary Plus® as a standard containment collar, without its right-up-to-the-line feature. Not compatible with GPS systems or indoor shields.
Replacement batteries for Invisible Fence® brand R21, R22, R51 and MicroLite® receivers are sold separately. Perimeter Technologies is not affiliated with Invisible Fence®.
