Laser level concept emerged in 1970s to help people in construction and architectural building. To explain how this device works, you should remember catechus plane lesson at school. Basic plane incorporates two points. Vertical line extends from up to down part and horizontal one goes from left to right infinitely. You have to determine two points in each of line then draw perpendicular invisible line as helper. When two drawing lines cross each other, you will get one precise point that belong to vertical and horizontal simultaneously. When you put this concept on the wall, drawing line from vertical and horizontal will guide you to make accurately straight line.
In construction, this device is very important. Builder digs drainage like hole as housing foundation then use laser level to adjust elevation angle and keep the position straight. In past time, this process needs two persons. The first one will set laser level and control beam in certain point. Meanwhile, the second one will do direct job to adjust soil and ground in precise level. Advanced device in this area is no longer two persons operation because one person can control laser level from distance through remote control.
