ABSTRACT:
A marker for locating an underground object such as a utility line features an elongate, flexible body, with an aperture near one end. The aperture has a “keyhole” shape which imparts sufficient stiffness in the marker so that it does not readily bend or flex at the aperture when handling the marker, while also allowing the marker to break near the aperture when a firm force is applied to the marker.
