DeWALT has announced two new self leveling lasers. They can auto level within 4 degrees of the laser being level. If it is out of the level the laser will blink like most lasers. The lasers provide a visible range of 100 feet and +/- 1/8 inch accuracy.
The DW08301 Three Beam Laser and the DW08801 Cross Line Laser will both be available at Home Depot in October 2014 for $99 each. AA batteries power them and they include a 3 year warranty. We hope to have a video on these soon.
