Abstract: A surface tracker includes a tubular marker body having an interior electronic marker and a visual indicator attached to an upper end of the marker body which extends away from the marker body. When deployed, the marker body is mostly underground and the visual indictor extends upwardly from the ground level to provide above-ground visual recognition. The electronic marker may be a passive electronic marker that includes a ferrite core assembly having a longitudinal axis which is generally parallel to a longitudinal axis of the marker body. The visual indicator may be a plurality of resilient filaments which pass through a hole in a tab portion of the marker body at the upper end thereof, the filaments being folded about the tab portion and secured to the tab portion using a heat-shrink tube. In an exemplary embodiment, the filaments extend about six inches from the marker body and are brightly colored. Multiple trackers can be used to mark the path of a buried utility.
