1. A laser alignment device for use with a drill rig having an elongate drill rod, the laser alignment device including a head unit having at least a pair of laser emitting devices mounted independently to one another thereon, each of the laser devices movable in one plane only and oriented in substantially opposite directions to one another to define an alignment plane, an attachment means to attach the head unit to a drill rig and a length adjustable assembly to adjust the separation distance between the head unit and the drill rod, wherein the alignment device is used to align at least the azimuth of the drill rod relative to survey marks utilizing the alignment plane. |
