The In-Ground Pet Fence System with Two Collars provides a customizable containment solution for dogs and cats, offering five hundred feet of wire that covers up to one third of an acre and can be expanded to five acres with additional wire. The system includes a digital LCD screen that displays boundary settings and alerts you to potential wire breaks, along with eight collar correction levels ranging from tone and vibration to adjustable static options suited to different temperaments. Each waterproof, rechargeable collar is designed for pets five pounds and up, with indicator lights to show low battery status and a quick charging time of two to three hours. This system is compatible with additional pet barrier accessories and can be installed as a simple do-it-yourself weekend project to create a safe, secure play area for multiple pets.
