❁【Accurate GPS Positioning】Our wireless dog fence uses GPS technology for stable and precise positioning, providing greater accuracy than traditional dog fences that can be susceptible to interference from metal or electronic products. The built-in advanced chip enhances the accuracy even more, making it a safer and more reliable option than similar wireless containment systems on the market.

❁【Advanced Safety Features】When the dog escapes the designated boundary, our GPS dog fence emits progressively increasing tones, vibration, and/or shock in 6 levels, followed by a 1-minute pause and a repeat cycle. If your dog still hasn't returned, the collar will emit a continuous beep until dog is back. The collar will stop warnings anytime when dog returns to the perimeter. Overall, these enhanced safety features are designed to provide maximum security for your beloved dog.

❁【Suitable Usage Environment】Our electric dog fence can cover a range of 99ft to 3280ft radius (33-1000 yards), making it adjustable to your desired size. It is best suited for outdoor areas such as open fields and is not recommended for use in small yards or indoors. The GPS accuracy is typically 1-2 yards but may decrease up to 5 yards in wooded areas. Waterproof IPX7 design makes it suitable for use in wet environments.
