ABSTRACT:
The present invention has a body with front and back surfaces, top and bottom sides, and two opposed ends. A display panel is on the front of the body. A processor is housed within the body. A dial can be connected to the front end of the body. The dial can have a head with an opening therein for allowing a laser beam to be projected from the head. A grid can be on the head for manually determining the angle between the longitudinal axis of the body and the head. The processor can electronically determine the angle between the longitudinal axis of the body and the head. The head can project forward from the front surface of the body. A side of the body can abut the side of a piece of material to be cut. A laser line can then be projected onto the material surface.
