Electronic Marker System
The 3M™ Electronic Marker System (EMS) helps save electric 
utilities time and money by enabling utility field crews to 
quickly pinpoint the location of buried facilities including cable 
runs, splices, vaults, conduits and road crossings. Using EMS 
markers during construction, installation and maintenance 
virtually eliminates the time consuming search for hard-to-
locate facilities.

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	Disk	Marker	is	also	available 	
for	marking	handholes.	These	markers	easily	attach	to	lids	or 	
covers	over	flush-mounted	facilities. 	
3M™ iD Markers
3M	iD	markers	are	designed	to	provide	an	accurate, 	
convenient,	long-lasting	method	of	marking	underground 	
assets.	In	addition,	these	markers	may	be	programmed	to 	
include	customer-specific	information	such	as	facility	data, 	
type	of	application,	material	type	and	size,	placement	date 		
and	other	important	details.
Near-Surface Marker
A small marker which is well-suited for bore holes 
in concrete or asphalt for marking flush-mount 
facilities prior to repaving.
Ball Marker
Ideal for most applications, with a 
unique self-leveling feature. The core of 
the marker floats in a non-toxic, non-
freezing liquid inside the ball; so the 
marker can be dropped in a trench, and 
the self-leveling feature will assure a 
correct orientation. 
Mid-Range
Designed for applications 
where less depth is required 
than with the Full-Range 
Marker. Marker spokes help 
stabilize it in the correct 
position after placement.Full-Range Marker
Designed for deep underground applications. 
Its large size makes it ideal for use as a digging 
shield over sensitive underground facilities.
The Safe Choice
There	is	no	guesswork	with	the	3M™	Electronic	Marker	System.	3M	markers	operate	even	in	the	presence	of	metal	conduit	or 	
pipe,	metallic	conductors,	fences,	AC	power	lines	and	electronic	markers	of	other	utilities.	All	EMS	markers	are	color-coded	to 	
APWA	standards	for	visual	reference	and	each	utility	has	its	own	frequency.	For	electric	utilities,	all	markers	are	red	in	color. 	
EMS	signals	provide	positive	identification	of	each	utility,	thus	helping	to	reduce	the	risk	of	accidentally	locating	and	excavating 	
other	buried	facilities.
