The 3M™ Ball Marker makes the job of precisely locating underground facilities easier. The 3M EMS Ball Markers have a unique self-levelling design that provides an accurate, horizontal position regardless of how the ball is placed in the ground. They have a range of up to 1.5 metres from marker to locator, and can be accurately located using a 3M™ Dynatel™ Locator.
The iD Markers can be programmed to include customer-specific information about the asset, such as the facility owner, conduit size, placement date, and other important details. The 1421-XR/ID Ball Markers are used in the Telecommunications industry.
