The boundary wire provides a flexible but reliable way to determine the mowing area so that the robotic lawnmower only mows on the specified surfaces. The small 50 meter coil is particularly useful when new plantings are made on the lawn or parts of the garden need to be rearranged in some areas. The required length can be easily extended to the existing cable. The same cable also serves as a guide wire and shows the robotic lawnmower the way back to the charging station. The high UV resistance of the Gardena boundary wire guarantees a long durability. Please use only original Gardena connectors if you want to connect two pieces of the boundary wire.This text is machine translated.
