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 underground water lines buried at a distance of 5 feet (1.5 meters)*. Markers help provide accurate identification of buried general purpose/reclaimed water lines, helping to reduce the risk of accidently excavating other buried facilities. Marker balls have a unique self leveling feature, that ensures the marker is oriented to the surface, allowing for an accurate location.
iD Markers can be programmed to include customer-specific information, such as the facility owner, conduit size, placement date, and other important details. This information can be accessed and changed by 3M locators with the iD function.
