Ideal 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 compensator that protects the inner pendulum during transport. Kit includes: 4 AA alkaline batteries, wall/ceiling mount, 8 ft grade rod, detector and clamp, tinted glasses, magnetic target, elevating tripod, and hard-shell carrying case.
