A line laser projects one or more laser lines onto the wall, floor or ceiling. Most line lasers have at least two laser lines, one horizontal and one vertical, which together form a cross. In the line lasers shown here, these laser lines are automatically aligned horizontally and vertically. The line laser replaces a spirit level and allows easy alignment of building elements or decorations.
With some line lasers the use of a laser detector is possible. With the laser detector, you no longer have to rely on the visibility of the laser line. This increases the working range and makes leveling in bright light (e.g. sunlight) possible.
