The 3M™ Near-Surface Marker provides an accurate, convenient, long-lasting

nnnn

method of marking underground and street-access facilities. Its size and shape

nnnn

allow for easy installation in asphalt, concrete or dirt, without extensive digging or

nnnn

drilling. The Near-Surface Marker is three inches long and 0.78 inches in diameter,

nnnn

and has a range of up to three feet (0.9 m) from marker to locator.

nnnn

The addition of the new 3M-ÌD markers provides additional functionality by

nnnn

enabling facility data to be stored in the marker. The pre-programmed unique

nnnn

serial number integrates with back office mapping and GIS systems when used

nnnn

for mapping new and legacy assets such as valves, handholes, manholes and other

nnnn

points of special interest.

nnnn

When buried in a vertical position, the Near-Surface Marker can

nnnn

be accurately located using a 3M™ Dynatel™ Locator. The locator

nnnn

transmits an RF signal to the buried marker. The marker returns the

nnnn

signal to the locator, indicating the marker's exact position, while the locator

nnnn

provides both a visual reading and an audible tone.
