Methods and apparatus for detecting a presence or absence of an underground facility and generating electronic records of locate operations are described herein. An exemplary apparatus includes an actuator and at least one receiver antenna to detect a magnetic field from the underground facility. The apparatus further includes a processor coupled to a memory, which may at least be further coupled to the at least one receiver antenna. Upon execution of processor-executable instructions stored in the memory, the processor logs in the memory locate information relating at least in part to operation of the at least one receiver antenna. The processor logs the locate information in response to actuation of the actuator and/or at least one event based at least partially on a characteristic of the magnetic field detected by the at least one receiver antenna.
