It is low if you placed the laser directly on the floor, such as the base of office slide bookshelf etc, but it is very useful in situations where the laser tripod is generally too expensive. Place the receiver or target plate on the base of the bookshelf, and if the horizontal line of the laser is a light receiver, the light receiving section. The height of the laser side can be finely adjusted with the tripod feet and the elevator so that it becomes the point height if the target plate. Rather than setting the horizontal line of the laser as the reference, the line of the laser is matched with the height of the base as a reference, so it does not become a halfway numerical value, the work is very smooth, There is nothing. Also, the 5 / 8-11 mounting screw and the center pipe of the tripod are hollow structure, it does not obstruct the black level point projection function of the laser level to be used, it can also be used for aligning the black line. Just as you can imagine from the price, the handle of the elevator and the fixing screw are quality close to "toy", there are parts that are unacceptable to those who are accustomed to Gitzo and Slick.
