My old foreman swore by the 'feel' of a backhoe bucket, but I'm all about the grade control screen now.
He'd have me eyeball everything, saying the seat of your pants was the best tech. After a job in Tacoma last year where we had to redo 200 feet of trench, I got a system with a 2D display. Do you think the old hands are right, or is sticking with the screen the only way to stay accurate these days?
