ABSTRACT:
A device for electronically marking a buried object, such as a service drop cable, comprising a reel for retaining the cable in a known position and orientation, and a transponder positioned at a predetermined location and orientation with respect to the cable wound on the reel. A foam shield may be used to provide a visual indication of the presence of the device, and an anchor may be affixed to the reel to secure it more firmly in the ground. The transponder can be located within the hub of the reel. The transponder can be active or passive.
