This wire is not intended for standalone use and must be used with an electronic transmitter to contain pets within a yard. 2. When used with certain foreign-version electronic transmitters, a thicker gauge wire may be required. Using a thinner wire may reduce signal strength, potentially affecting receiver performance and pet containment. 3. Some foreign-version systems are designed for thinner wires with lower output power, resulting in a shorter detection range (approximately 1 meter/3.3 feet). This limited range may reduce effectiveness in preventing pets from leaving the designated area. Package List: 1 x Electric Dog Fence Wire
