3M™ Dynatel™ EMS iD Full-Range Markers help provide an accurate, convenient, long-lasting method of marking underground facilities. The marker has a range of up to eight feet (2.4 m) from marker to locator.
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. *Depth range may vary on "E" (export) models - refer to product specifications.
