Be honest, do you check floor surfaces completely and accurately every time? This was almost impossible anyway with the previous point-by-point methods. Or if at all possible, it would require a lot of time and personnel. This is now visibly easier to do because the new GSL 2 Professional enables you to check floors completely in no time. It is ideal for everyone who works with floor surfaces - for composite floor layers, tilers, parquet layers, drywallers and surveyors.
The principle is ingeniously simple - and simply ingenious. The floor surface laser projects two lines onto the floor. If the surface is flat, the lines will be exactly on top of each other. The user will see them as only one line. Where the lines are apart, the floor is not flat.
