Abstract
A device for electronically marking a buried closure has a transponder and a shield or cover affixed to the transponder in such a manner that, when attached to the buried closure, the transponder is positioned at a predetermined location and orientation with respect to the known position and orientation of the buried closure. The shield can have a raised portion housing the transponder, and is preferably elongated with an arcuate cross-section, generally larger than the buried closure.
