DeWalt DW0851 Self Leveling Spot Beams and Horizontal Line Lazer

I tried out the laser level with disappointing results. The 5point laser that I got from dewalt 2 1/2 years ago out performs this laser in its accuracy and low movement of laser as the spans increase. You can see the difference in performance in 15ft by less than a 1/16. but the difference
between the old laser and this one become obvious when we are trying to pass control points 3 to 4 floors (30 - 45ftwhere the old one keeps a grouping of points 1/4in which is 1/8in off of true center while the new one is 1/4in to 5/16 from true center. We have put the old and the new one to a head to head test and our 2 1/2 year old laser is more stable and constantly gives us better grouping
