Image Number 2 for United States Patent #6371692.

A device for ground burial with an underground utility line or element and useful for early detection of the underground utility line or element during the excavation. The device has at least one sheet of non-conductive material, indicia on the sheet forming a cautionary message indicating the presence of an underground utility line or element, and at least one support element for vertically positioning the device in the ground. Further, a method for early detection of a underground utility line or element during excavation. The method includes burying at least one of the above-described devices in the ground along a side of an underground utility line or element so that the device is positioned vertically in the ground and extends up toward the surface of the ground from the underground level of the underground utility line or element.
