The 3M™ Dynatel™ EMS Near-Surface Markers help provide an accurate, long-lasting method of marking underground facilities.
iD Markers can be programmed to include customer-specific information, such as the facility owner, conduit size, placement date, and other important details. This information can be accessed and changed by 3M locators with the iD function. This can all be done without the need for an external power connection.
