A plumb-bob device has an enclosure with three lasers projecting from one end, one of which projects a horizontal lane, one in a vertical plane, and one with crossed planes from a laser that is suspended to swing but not rotate about an axis. The device may be attached to an object to be leveled or plumbed, and moving the object until the lasers coincide accomplishes plumbing the object.
