Comments about DeWalt DeWalt DW087K Self Leveling line Laser:

I purchased this laser level ... to assist with the surveying on a long cement driveway project. The driveway was 120' feet long and was much longer than traditional water level & line level techniques would remain accurate. [...]. It was relatively simple to set up, even for one person. Some have complained that this unit is not an autoleveler, but I specifically chose it for that property.
