Abstract
A locator device and methods of use are disclosed. The locator device includes a first locating system configured to generate to sense an electromagnetic field emanating from a sonde associated with a drill head, and a second locating system including a global positioning system. The locator device includes a display on the locating system configured to display a map of the area in which the locator device resides based on a location detected by the global positioning system. The locator device also includes control electronics configured to, upon receipt of an input from a user, record location data in a memory associated with the locator device for use by a horizontal directional drilling control system.
