Bridging the drawbacks of rotary- and cross-line lasers, the GLL2-80 is the world’s first 360-degree dual-plane line laser. It projects lines on both vertical and horizontal planes, making such tasks as aligning and leveling cabinets as easy as pie. Capable of switching from dual-plane to vertical- or horizontal-only modes, the unit has few moving parts so it will last longer. Cost: about $400. Bosch Measuring Tools. 877-267-2499.
