Using a plotting board to accurately determine an azimuth and distance

---

This block is not in a published chapter and should not be relied upon.

A plotting board can be used to more accurately determine azimuth and distance. To do so, follow the procedure:

1. Centre the plotting board on the origin point.
2. Rotate the base board or ruler to intersect the target point.
3. Read the azimuth using the Vernier scale.
4. Measure the distance using the plotting grid.
5. If the target is over 3km away, use the lower-left origin.

You now have an accurate azimuth and distance.
