Guidance lines are parallel lines which are displayed on the terminal screen. These help you to treat the field in parallel lines.

The first guidance line which you lay out on the terminal is called the AB line. On the terminal screen, these are usually marked with the letters A and B. All further guidance lines will be calculated and designated on the basis of the AB line.

The path of the AB line will be saved after the first drive-over, which you must perform manually. The operation of the terminal will depend on the guidance mode that you have chosen.
