The intelligent way to manage your underground network
The Smart Choice
A feature exclusive to the Dynatel EMS locator is the ability to read,
write and lock programmed information into 3M™ Electronic iD Markers.
3M™ iD Locators are able to pinpoint the depth and location of existing
models of properly installed underground markers — easily differentiating
between standard frequencies.
Detailed information can be read, stored with date/time stamp and
transmitted back to your PC for enhanced resource management through
a standard RS232 serial port or USB port. iD locators are now compatible
with selected GPS/GIS instruments to greatly simplify the mapping process.
How they Work
The 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, while the locator provides
both a visual reading and an audible tone.
3M Electronic Marking System
The 3M™ Electronic Marker System helps eliminate guesswork.
3M™ Markers provide an accurate, convenient, long-lasting method
of marking underground facilities. Electronic marking saves time and
money spent searching for buried facilities prior to excavation.
Unlike surface markers such as stakes, flags or paint, the electronic
markers cannot be inadvertently moved or worn away by weather.
Markers that Last
With our Full-Range, Mid-Range, Ball and Near-Surface Markers , there is a marker
to meet almost every need. Markers are passive antennas with no internal power
source to run down. Their water-resistant, polyethylene shells are impervious to
minerals, chemicals and the temperature extremes normally found underground .
A four-inch 3M™ Disk Marker is also available for marking hand holds.
These disk markers easily attach to nonmetallic lids or covers over flush-
mounted facilities. 3M™ Markers operate even in the presence of metal
conduit or pipe, metallic conductors, fences, AC power lines
and electronic markers of other utilities.
