Designed for professional use, the DeWalt DW073KD 9.6-volt-to-18-volt Ni-Cad Cordless Interior/Exterior Rotary Laser Kit's manual leveling system is accurate to +/-1/4 inches per 100 feet. The rotary laser features dual side-by-side laser diodes for an extremely bright, visible beam and variable speeds (0-to-600 RPM) for increased visibility. Other features include a protected rotary head and side impact roll cage for increased durability, a built-in bump sensor that alerts you if laser has been bumped after leveling, and the laser can be oriented level or plumb for all common applications.
This laser's multi-voltage adapter accepts all DeWalt 9.6-to-18-volt batteries and its built-in wall, floor, and tripod mounts allow fast and easy set-up for most common applications while eliminating the need for separate tool mount accessories. An included digital laser detector extends interior and exterior range to 600 feet. Backed by a manufacturer's 3-year warranty, this rotary laser comes with a one-hour charger, an 18-volt battery, a laser target card, a digital laser detector and clamp, laser enhancement glasses, and a heavy-duty kit box.
