For a barn expansion, rectangle with 4 unequal sides, the horizontal must be created right in the middle. From horizontal to determine several right angle for the room arrangement was required. Using the laser, the tile was quick and easy for us to provide a lot of self-Leist narrowing in the conversion, on the stage. The laser beam scattered over a Enfternung of about 12 m - for the determination of horizontal - about 1/2 cm, which was known by the product description and did not matter. When creating the right angle for the individual rooms were smaller and the distances of the laser worked precisely and clearly visible.
