The S2 is an electronic laser tool used by professionals and do-it-yourselfers for projecting horizontal and vertical "chalk line" laser beams. Used for squaring and leveling tiles, floors, paneling, cabinets, drywall, wallpaper, studs, finish carpentry, wainscoting, plumbing and electrical outlets, the device easily allows one person to do layout work on both horizontal and vertical surfaces and the rear-molded scale allows angles to be laid out in 5-degree increments. In addition, the low price is well within the pro and DIY price ranges. Currently, 1,700 Home Depots feature the product and it is selling at a very good pace, meeting all marketing projections.
