Rotary laser Levels are a very useful innovation that are becoming more and more commonplace. They produce an even line along a horizontal plane and can be thought of as a "electronic chalk line". They make it simple to level things and are useful for drywall and ceiling installers, masons, and remodelers. They are even great for uniformly hanging up pictures in a room. The DW073KD is a cordless rotary laser level that's durable, portable, and accurate. Like everything else on this list, it's powered by DeWalt 18v XRP batteries.
