After laying the GARDENA boundary wire, the GARDENA robotic lawnmower immediately knows where to mow. The small package of 50 meters of wire is especially handy if you need to re-lay the boundary wire due to newly planted or remodeled areas in the garden. The already laid cable can be easily extended to the desired length. The same wire serves as a guide wire and shows the robotic lawnmower the way back to the charging station. Always use original GARDENA connection elements if you want to connect two boundary wires.
