3M™ EMS Full-Range Marker

Deep-burial underground point marker — detection up to 9 ft.

The 3M EMS Full-Range Marker is the deepest-detecting point marker in the 3M Electronic Marking System range, suited for deep applications of up to 8 to 9 feet. It is the right choice wherever buried assets lie at significant depth — where other marker types would fall short of the required detection range. Available in orange for Gas utility identification (and in colour variants for other utility types per APWA standards), the Full-Range Marker provides the same core advantages as all 3M EMS markers: no batteries, no maintenance, no wiring, and reliable operation across all soil types and environmental conditions. The iD version of the Full-Range Marker additionally allows the storage and field retrieval of customer-specific asset data, accessible through any 3M Dynatel iD-capable locator or via GIS system upload.
