Ive never been around any laser systems that are automatic. But in my 9 years in the trade the only one I have been around consistently is the apache bullseye system. While it is still a manual system, a competent operator can get premium results using it. The old finish dozer man that taught me used one of these, and could grade a flat pad within a hundredth, confirmed by surveyors using a total station. http://www.engineersupply.com/Apach...l-Laser-Receiver-with-Alkaline-Batteries.aspx
