The long-range radio frequency has an operating distance of up to 650ft/200m. If that distance is too large, you can adjust the levels from 0 to 100, which corresponds to 0-650ft/0-200m.

The wireless Fence is waterproof, rechargeable and ultra-durable. If your dog exceeds the range you've established, the receiver will initiate its training function automatically, which will remind your pet to return your designated safe area. It will start by vibrating for 3 to 4 seconds and then punishes with electric shocks. If your pet continues to leave, the process will repeat until your dog returns home. Most pets learn very quickly, and rarely test their new boundaries. After all, they’re busy and happy, enjoying their freedom.

There are three different levels of electric shock.  "strong", medium", and "weak", these levels are freely configured.

Gps Wireless Electric Dog Fence features:

• Invisible environmental protection: The wires are buried in the ground, do not occupy space, don't affect your garden looks, gives the dog more freedom.
• Progressive Tone Stimulation: When the dog approaches the border, a warning sound is first heard. If it continue to approach the limit, the system will make a slight impact.
• High Tech Safety Device: Pulse Proportional Stimulation. The vibration intensity depends on the distance of the dog near the boundary line, the closer the dog is to the boundary line, the greater the vibration intensity.
• Wide Range Control: Up to 5,000 square meters, equivalent to a football field is so big, and variable range, quite flexible.
• Safe And Reliable: Once the wires buried in the ground are damaged, the wire damage indicator will give a loud warning and flash. And the lightning protection device on the converter can avoid lightning strikes
