1. A system for marking an underground utility line, comprising:
- a beam transmitter configured to emit electromagnetic radiation;
a distal target oriented to be impacted along a first target surface by at least a first portion of the electromagnetic radiation, the distal target being mounted on a target stand configured for adjustment with respect to a vertical axis;
a target applicator including—
a second target surface;
a base having a shaft; and
a container attached to the base and configured to hold and dispense markers for placement along a ground surface that extends between the beam transmitter and the distal target.

Abstract
A ground surface marking system including a beam transmitter configured to emit electromagnetic radiation and a distal target. The distal target is oriented to be impacted along a first target surface by at least a portion of the electromagnetic radiation. The distal target is mounted on a target stand configured for adjustment with respect to a vertical axis. The system also includes a target applicator having a second target surface, a base including a shaft, and a container attached to the base and configured to hold and dispense markers for placement along the ground surface extending between the beam transmitter and the distal target.

19. A method for marking an underground utility line, comprising:
-
locating a first reference location along a ground surface above the utility line; locating a second reference location along the ground surface above the utility line and spaced from the first reference location; providing a beam transmitter configured to emit electromagnetic radiation; placing the beam transmitter substantially above the first reference location; providing a distal target including a first target surface, the distal target being mounted on a target stand configured for adjustment along a vertical axis; placing the distal target substantially above the second reference location; orienting the first target surface to face the beam transmitter; adjusting the target stand with respect to the vertical axis until the first target surface is impacted by at least a portion of the electromagnetic radiation; providing a target applicator having a second target surface; placing the target applicator between the beam transmitter and the distal target; aligning the second target surface with at least a portion of the electromagnetic radiation; and actuating a container to release a marker for placement along the ground surface. - View Dependent Claims (20)
