Description

The 3M™ Marker Ball makes the job of precisely locating underground geothermal pipe, loop boreholes and fittings easier. The 3M marker ball’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 # 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.

Later, the marker ball 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 audible tone.
