This GPS wireless dog fence system creates a virtual boundary for your pet without requiring physical barriers. The system combines fence functionality with real-time GPS tracking, allowing you to monitor your dog's location through the iOS Finder app. The adjustable radius ranges from 32 to 2887 feet, covering up to 760 acres, making it ideal for yards of various sizes or temporary containment needs during travel. The GPS receiver features three training modes: beep, vibration, and static shock. When your dog approaches or crosses the established boundary, the receiver activates these alerts in sequence until your pet returns to the safe zone. The built-in tracker helps you locate your dog by displaying their position on an e-map and providing route guidance to find them quickly. The rechargeable battery provides up to 72 hours of standby time after a full charge. The IPX6 waterproof rating ensures reliable performance in various weather conditions. The adjustable collar fits small, medium, and large dogs comfortably. This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
