Congratulations! You have just purchased one of the finest, most advanced Electronic
Marker locating devices available today!
The 3M™ Dynatel™ Marker Locators 1420-iD and 1420E-iD are designed with all of the
functionality of previous Dynatel models, with the enhanced capability to read from,
and write user information into, 3M iD Markers. Information such as a pre-programmed
unique identification number, facility data, application type, placement date and other
details can all be read, stored and downloaded to your PC for enhanced resource
management with this revolutionary equipment. The Dynatel Marker Locators 1420-iD
and 1420E-iD will also search for two different types of utility markers simultaneously.
When used in conjunction with a hand-held GPS device, the ability to transmit path and
marker coordinates multiplies the potential to the mapping industry. This equipment
provides a simple system for mapping utility information directly into CAD and GIS
systems.
3M is dedicated to bringing you premium equipment with outstanding reliability, backed
by one of the best warranties in the business and outstanding service.

The information from the iD marker, as well as the GPS coordinates, will display on the
locator display. This information is saved automatically in the Read Marker History. (See
8.A. Reviewing Marker Read/Write History.)
If the marker is a passive marker (rather than iD) the locator will display “No iD Marker
Found”. The GPS coordinates of the attempt to read the non-iD marker are stored in
the Read Marker History as serial number # 0000-0000-0000. The marker details will
indicate “not an iD marker”, but will display the GPS coordinates.
C. Sending iD Marker Data to GPS (Capture-Transmit Mode / Mode 2)
Menu [6] + COM Setup [SK:3] + GIS
Locators that have marker locating capability (indicated by ‘iD’ in the model number)
can be configured to send 3M™ iD Marker data directly to some GPS devices. When
an iD marker is located and read, the information read from the iD marker, with feature
and attribute data, is sent to the GPS device and is stamped with latitude, longitude and
date/time data. The data acquired during this logging process can be uploaded to GIS
mapping software. For more information and detailed instructions pertaining to specific
