Marking apparatus and methods to mark ground, pavement or other surfaces to provide a visual indication of a presence or an absence of an underground utility in a dig area. An example marking tool has a hand-held housing, a marking dispenser coupled to the housing to dispense one or more markers in the dig area, and a triggering system to trigger the marking dispenser so as to dispense the marker(s). An example marking tool also may include a logging system to receive data associated with a marking event initiated by the triggering system, time tag the data, and store the time-tagged data in data storage in the marking tool.
