Cordless rotary laser by DeWALT

The DW077 fully automatic self-leveling cordless rotary laser is accurate to 1/8 inch per 100 feet. An out-of-level shut-off feature ensures reliable level and plumb referencing. The tool features an easy-to-use control panel, fully automatic one-button leveling, and a wireless remote control for fast and one-person setup. The laser has a high-power laser diode to produce an exceptionally bright and sharp beam. The beam is visible indoors up to 100 feet from the unit (200 feet diameter), and can also be used outdoors with the digital laser detector at a distance up to 600 feet.
