3M™ Electronic Marker System (EMS)
The 3M™ Ball Marker makes the job of precisely locating underground facilities
easier. Other buried markers can be disturbed by backfill dirt or installed improperly
so they don’t stay positioned correctly. The 3M ball marker’s unique self-leveling
design ensures the marker is always in an accurate, horizontal position regardless of
how it is placed into the ground.
The addition of the new 3M-iD markers provides additional functionality by
enabling facility data to be stored in the marker to ensure positive identification of
facilities. The pre-programmed unique serial number integrates with back office
mapping and GIS systems when used for mapping new and legacy assets and points
of special interest for construction and maintenance applications.
The ball marker is buried over key facilities during construction or
maintenance. Later, the marker is easily and accurately located using a 3M™
Dynatel™ Locator. The locator transmits a signal to the buried marker. The
marker returns the signal to the locator, indicating the marker’s exact position.
The compact electronic locator gives both a visual reading and an audible tone.
