Abstract
Location systems and methods for locating paint and other markings on a surface are disclosed. A paint marking stick may include a magnetic field sonde that is actuated in conjunction with dispensing of paint or other markers, where the sonde generates a magnetic field signal in conjunction with dispensing of paint or placement of a marker. A corresponding utility locator may receive the sonde magnetic field dipole signal and determine and store positional information and type information associated with the paint or other marker.
