Abstract
Abstract A locating device is disclosed which includes: underground object locating means (24, 26); positional data receiving means (6) for receiving data relating to the geographical position of the locating device; and data storage means (12) for storing data relating to the position of the underground object (16) as determined by the geographical position of the locating device (14). In this way the geographical positional data is stored relating to the location of the underground cable, and may be subsequently retrieved for relocation of the cable.
