The 3M Marker Balls allow for the easy marking of underground water lines buried at a distance of 5 feet (1.5 meters). Marker balls have a unique self leveling feature, that insures the marker is always oriented to the surface, allowing for an accurate location. Passive marker balls provide accurate identification of buried water lines, helping to reduce the risk of accidently excavating other buried facilities. All markers function without the need for an external power source. Their water resistant polyethylene shells are impervious to minerals, chemicals and the temperature extremes normally found underground. An iD version is available which allows for the storage of customer specific information about the underground asset.
