3M™ EMS Marker Balls

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. Smart technology use of a well established radio frequency application.


  • Using EMS Markers during construction, installation and maintenance virtually eliminates the time consuming search for hard-to-locate facilities
  • High accuracy – mis-locates are significantly reduced
  • Long lasting passive antenna encased in waterproof shell helps identify underground facilities for years to come
  • The water-resistant polyethylene shells are impervious to minerals, chemicals and the temperature extremes normally found underground
  • All markers function without the need for an external power source
  • Frequency and colour coded helps to identify the specific utility – Water, Gas, Power, Sewer, Recycled water or Communications
  • Operating temperature spans from -20 to 50⁰C

3M iD Markers can be customized to include customer-specific information such as facility data, type of application, material type, size and placement date.
