Abstract

A locator device for generating buried asset data is disclosed. The device includes an elongated housing accommodating at least two sensors, wherein each sensor is for reading analog radio frequency (RF) signals from a buried asset, wherein the at least two sensors having a known distance between them, and wherein the housing may be oriented either horizontally or vertically, a sensing device for sensing an orientation of the elongated housing, and a processor for reading RF signals from the buried asset, applying an orientation filtering process to the signals based on the orientation, converting the signals into buried asset data having depth data, position data and electrical current data for a buried asset, and, a display unit for displaying the buried asset data in a graphical user interface, wherein the buried asset data corresponds to the RF signals that were read.
