Sounds about right for those old sales brochures...

But honestly, how often do people even look UP at your ceiling?

Heard a story from a buddy who runs a grading crew. They were using the new GPS on a big pad site, everything going smooth off the screen. Then the system had a hiccup, just a tiny one, but the dozer was off by like two feet before anyone caught it. They had to stop and bring in a guy with a transit to double check the whole corner. Makes you wonder if we trust the screen too much sometimes. That old way of checking stakes kept you in touch with the dirt.
