Rotary Laser Levels

A rotary laser level is a device that is used in construction to get straight-line references along a surface or to get a horizontal level on a certain height. This is achieved by emitting a 360 degree laser beam, after horizontally levelling the rotary laser level device. Many rotary laser level types can be used with a laser detector or a grade rod excavator. Important factors in buying a rotary laser level are the range of the laser, its rotational speed, an adjustable rotation angle and self-levelling capacities.
