When creating a job only the Job Type, Date, and Surface(s) are required fields. You can select all surfaces of a type, for example ALL Greens, or you can select individual surfaces for specific treatments.
If you are going to select a piece of equipment for the job this must be previously setup.
Upon selection of the surfaces drop down you will see items grouped by surface type. These are all the surfaces for the currently selected golf course. Selecting the main level checkbox will quickly select all surfaces of that type. You can select the arrow to identify specific surfaces on a hole(s).
