The 3M™ Dynatel™ EMS Extended-Range Ball Markers have a self-leveling design providing accurate, horizontal position regardless of how it is placed in the ground, helping to make the job of precisely locating underground facilities easier.
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.
