The 3M™ Electronic Marking System (EMS) Warning Tape 7900 Series is engineered to provide visual verification of underground utilities. Features include radiofrequency (RF) path marking technology for locating. The RF technology does not require an electrically continuous path to provide detection in places where the tape has been damaged or detection where it is prohibitive or too congested to have a tracer wire.
