From the Manufacturer
The Matrix 54 is the most versatile laser tool available for the general or interior contractor. With 4 Laser-Crosses at 90 degrees to each other and a laser cross on the ceiling, the Matrix 54 sets itself as the most useful laser tool available. Laser lines are individually switchable allowing you to put laser lines only in the areas you want. Additionally, a graduated circle and tangent knobs make rotating the Matrix 54 an ease to get on line. To keep you from making any errors, the Matrix 54 also has a visible alarm to indicate unwanted position movement. You can even use it with your standard 5/8x11 tripod.
