Tips

1. Use the 'Maximize This Map' option to generate a large map window to work with - it makes things a lot easier.

2. The current view of the map can be panned to a new position by pressing the left mouse button and dragging the map.

3. Bearings are given in both absolute map numbers, and compass-corrected for the local magnetic declination value, which is also listed. If your compass lets you adjust the magnetic declination, you have the option to do that and use the uncorrected map bearings.
