Have used Trimble UTS on many rd jobs on a grader. Most jobs have +\- .04 so it’s very accurate. I’m my experience your set up will dictate how your day goes. Dump trucks, rollers, telephone poles even your own cab could block your line of sight so you have to put a little thought in it and plan your set up. Some projects such as PENNDOT requires you to use the UTS instead of GPS.
