3M™ EMS Full-Range Markers 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.
Full Range markers are ideally suited for marking the location of utilities buried at a deep distance (8 feet or 2.4 meters). Markers provide accurate identification of buried water lines, helping to reduce the risk of accidently excavating other buried facilities. It also has a water resistant polyethylene shell, which is impervious to minerals, chemicals and the temperature extremes normally found underground.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.
