The GPS Wireless Dog Fence System offers a lifetime free app with no subscription fees or hidden charges, allowing users to set up virtual fences for up to 3 dogs simultaneously. The adjustable silicone collars fit dogs from 8-27 inches in neck size and are suitable for dogs over 3 months old. The boundary radius is customizable from 65 to 3280 feet, with precise 1-foot increments. This 2-in-1 system integrates a containment fence and a dog training collar, enhancing GPS signal stability compared to traditional Wi-Fi systems. It safely restricts your dog's activity range while cultivating good behavior habits, strengthening the bond between you and your pet. The intuitive app enables drawing circular, rectangular, or polygonal (up to hexagonal) electronic fences, adapting to irregular courtyards or complex terrains. When the dog approaches the boundary, the collar emits an audio alarm as a gentle reminder. The system offers customizable correction modes, including light, sound, vibration, and electric shock, with independently adjustable intensities (0-5 levels) for vibration and electric shock. This ensures personalized training plans based on your dog's size, personality, and adaptability. With a rechargeable battery providing up to 48 hours of continuous use, the system features an intelligent power-saving mode. It automatically enters sleep mode after 2 minutes of inactivity and wakes up instantly upon detecting movement. The IP7 waterproof rating ensures normal operation in rain, swimming, or muddy conditions. The newly upgraded Dual-Core GPS positioning chip offers superior anti-interference, sensitivity, and energy efficiency, maintaining simultaneous connection to multiple satellites for uninterrupted performance in challenging environments. Upgrade to experience enhanced accuracy and additional features, allowing your dog to play freely and safely within the designated wireless range.
