I finally stopped fighting GPS machine control after a foreman in Tucson showed me how he checks it
I used to think GPS on a dozer was a crutch for guys who could not read grade stakes, and I argued about it for hours with a foreman named Ray on a job off Speedway Blvd in Tucson last month. He walked me over to his blade, pulled up the receiver readout, and showed me he still shot a hub every 50 feet to cross-check the display, and the numbers matched every time. It bugged me for a week, then I realized I was not against the tech, I was against the guys who trust it blind. Anyone else run a daily cross-check like that, or do you just trust the screen?

Shooting a hub every 50 feet kind of proves my point though. If the screen was actually right you would not need to double check it with a tape and a level. That foreman is doing the tech's job for it. Give it a few years and the new guys coming up will not even know how to run a hub, then what happens when the satellites drop out or some cloud rolls in?
