I embraced this tech early on, had an uncle that tiled so we had the equipment. You start doing building(hog) pads 80x200, with specs +/_ 1in, ain't nobody that good, with the lazer we got to +/_1/2in, concrete guy's liked us. Course all my stuff merely had reference lights and not controlled, having that saved me labor and gained jobs because of it. I will add that older equipment takes a lot of $$$ to go total control, something we never did.
