The Spotline laser vehicle spotting guide projects a green laser line directly in the center of the bay. The technician centers the line on the vehicle hood and dash while pulling in for accurate positioning. The Spotline retrofit kit works with two- and four-post surface lifts, light-duty inground lifts, and heavy-duty parallelogram and scissor lifts, and officials said it can be used for school buses. The kit comes with a Spotline laser assembly, a motion sensor kit and a mounting bracket.
