The description and the manual seems to me by a program and not by someone who really can be translated German. So it took a while before I understood that the Lazerpunkt only the center of the area is measured and the measured area is increased through the measuring distance. When measuring distance of 6m-diameter is at least half a meter. Otherwise, the device works surprisingly well. I have the device used to in my house - now where it's cold outside - cold bodies to determine. If the description better I would have awarded five stars.
