you’ll see 3 options: Add Fence Post, Edit Name, and Delete. You can
edit the name of the Map Area now, or change it later. Select “Add
Fence Post” and press OK. The default name for your first Fence Post is
“FP001”, this can be changed later if you like.

• Keep using “Insert After” to add Fence Posts until you have placed
at least three or four to define the boundaries of the Map Area you
are creating. Press EXIT or the LEFT key to see the Map Areas List, with
your new Map Area added. With the name of the Map Area selected,
press the RIGHT key to view the Area on the base map, with lines
visible between the Fence Posts. The Info Box at the bottom of the
display will automatically show the total area (in square miles) of
the Map Area. If your Map Area is very small, the Info Box changes to
square feet instead of miles. If you need to know the area in acres, 1
sq. mi.=640 acres, so simply multiply the number in the info box by
640. For small areas, divide the square feet by 43560 to see the total
area in acres.
