The GPS electronic fence equipment is designed to create a dog park to contain your dog safely playing around in your yard without digging and Burying Wires. The newly upgraded system can cover 990 meters depending on the Customer’s needs. There are four modes of positioning functions (GPS+ BD + Galilean +Glonass), and supporting up to three positioning patterns. The system operates the alarm system (beep/vibration/shock) to warn dogs while he go beyond the boundary zone you set up and remain peaceful while pets are within the boundary zone.

Open box. Tested. Please note this product is intended to function with clear GPS satellite connection (such as a field) and may perform poorly in areas with obstructed signal.
