With the Grimsholm signal cable tracker MS6818, you can both find and troubleshoot the signal cable for robotic lawnmowers (even if the cable is deeply buried) very easily.
The equipment has been preconfigured to have the settings that are optimal for troubleshooting robotic installations in particular, but can also be used for a variety of other purposes such as identifying pipes and electrical wiring in walls, troubleshooting electric underfloor heating, checking the voltage in wall sockets, etc.
Instructions that guide the search for breaks in the robotic lawnmower's boundary cable are included together with cables, alligator clips, test probes, earth spike, bag and batteries.
