The 3M™ Dynatel™ EMS Extended-Range Ball Markers have a self-leveling design providing accurate, horizontal position regardless of how it is placed in the ground, helping to make the job of precisely locating underground facilities easier.
The 3M™ Marker Balls allow for the easy marking of wastewater lines buried at a distance of 5 feet (1.5 meters)*. Marker balls have a unique self leveling feature, that ensures the marker is oriented to the surface, allowing for an accurate location. Passive marker balls provide accurate identification of buried wastewater 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. *Depth range may vary on "E" (export) models - refer to product specifications.
