A workhorse for small jobsites, this rotary self levels in the horizontal plane and manually levels in the vertical plane. The rotary also features an illuminated vertical vial and adjustable rotational speeds of 200, 400 or 600 RPM. Accuracy is never a problem thanks to the visual and audible alarms that alert you when the rotary is beyond its leveling range and the locking pendulum that protects the inner pendulum during transportation. For a complete leveling system, consider Johnson's 40-6516 rotary laser kit or 40-6517 rotary laser system.
