A rotary laser level set up and used to level sand fill in trenches. The graduated staff is leaning on the pile of sand.
In surveying and construction, the laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod. The tool is leveled according to the accuracy of the device and projects a fixed red or green beam in a plane about the horizontal and/or vertical axis.[1]
