Designed for identifying and checking horizontal and vertical lines in interiors. Projects horizontal and vertical beams for identifying the alignment of objects with the laser lines, as well as two perpendicular beams and a laser point that works as a light plummet. Exceeding the level limit is indicated with an acoustic signal. Accuracy: 2.5 mm/5 m (2.0 mm/3 m for point), lock screws for accurate device setting, 5/8" (16 mm) thread for tripod attachment; rotary stand for 360°, self-levelling range: ±3°, self-levelling faster than 5 s, effective laser range: approx. 10 m, power supply: 2 × AA, laser line thickness: 2 mm ±0.5 mm/5 m, dimensions (incl. stand) 100 × 90 × 145 mm, weight (excl. batteries) 460 g, laser class II, nylon case.
