If we're grading a lot, we'll check along the lot lines and through any swails we've cut, to be sure we've got them sloped the right way, and consistently sloped. Can't really stake those areas, because if we're off by a little, we go back through with the equipment to adjust the grade.
Also, when setting screed pipe over a great length, I prefer the laser to a string and stakes. For any smaller projects or in a compact area, we may not use the lasers at all.
Also, I have a guy that is allergic to shovels, so he seems to find all kinds of reasons to need the laser.
