The DeWalt DW074KD is a self-leveling rotary laser kit for interior and exterior layout work. It projects a rotating beam up to 600 RPM and is accurate to about 1/4 inch at 100 feet, with range extendable to 600 feet using a beam detector. It runs on two D batteries and has weatherproof construction for outdoor use. Buyers report poor reliability and short life, so it suits occasional layout work better than daily professional use.

The DEWALT Self-Leveling Int/Ext Rotary Laser Kit helps set a level plane for a building. It levels itself and sets up on a horizontal axis. It runs on 2 D batteries and delivers many readings on a single set.
It is accurate to 1/4 inch at a distance of 100 feet, so it can be used to set an entire floor. For larger projects, a beam detector extends the range to 600 feet. The rotation speed is up to 600 RPM.
The construction is weatherproof, which protects it from rain, wind and other harsh conditions.
