Rotary laser levels spin a light beam in a full circle to project a leveling reference line from all sides. Also known as spinning or rotating laser levels, they provide better visibility and a greater working range than dot, cross-line, and plane laser levels. Indoor uses include aligning framing and structural components, especially in warehouses and other large spaces. Outdoor uses include performing site layouts, establishing grades and drainage, leveling foundations and footings, aligning fence posts and masonry, and setting up retaining walls and terracing. Their performance is enhanced by mounting them on a tripod that provides secure support and precise positioning. They are commonly paired with a laser receiver to detect light beams in daylight.
