Trimble GCS900 Tip - How to add an adjustment to match surveyor

Shows how to use an additional offset in Trimble GCS900 Machine Control GPS to make a small adjustment to match in with a surveyor or a cut / fill mark on the ground without having to mess up your normal vertical offset if you are chasing known offsets above or below grade.
This is the Working Surface option under the Vertical Offset page.
