RANGE: The E-FENCE 3500 system comes with 500 feet of 20 gauge wire and additional wire can be purchased to cover up to 40 acres. It’s an effective underground containment system that allows your dog the freedom to run around while also being safe on your property. SIGNAL FIELD WIDTH: Adjust the width of the distance from the boundary wire that the receiver will activate. You can control the area that your dog is in and provide either a shorter or longer field width for your dog to be in. FILTERING SYSTEM: The E-FENCE 3500 comes with an advanced filtering system to keep it operating properly. It prevents outside electrical sources from accidentally activating the fence, so you can be sure that the only source activating it is the transmitter.

【Safe Efficient Electric Dog Fence System】Equipped with buried wires and a wall-mounted transmitter, our system helps train dogs to establish the habit of staying in their own independent space. This not only keeps your furniture and daily necessities clean and tidy but also spares your pets from the discomfort of traditional fences. Ensure your dog stays within the specified safe area so you can have peace of mind when you go outside. Perfect for dog training at home or on field trips, this versatile system is ideal for maintaining control and safety. 【Effortless Dog Training】With our electric dog fence system, the collar springs into action as soon as you install it. As your dog attempts to cross the boundary wire, the collar emits a beep and delivers a mild shock. The closer your dog gets to the boundary, the stronger the shock becomes, effectively reinforcing the training and guiding them back to the designated play area. 【Customizable Boundary Settings】The electric dog fence allows you to control the width of the boundary by adjusting the knob, offering a customizable range of up to 1.2 acres (53,189 square feet). A wire break warning alerts you promptly if the wire is broken, ensuring continuous operation. Additionally, the red low-power indicator prompts you to replace the collar power, preventing intermittent functionality. This invisible fence for dogs is designed for maximum reliability and safety.
