7.9 Measuring distances, ranges and bearings
When you are using the radar application, you can measure distances, ranges and
bearings in a variety of ways. These options are detailed in the table below:
... Using the range rings
Use the range rings to gauge the approximate distances between points. Range rings
are concentric circles displayed on the screen and centred from your boat at pre-set
distances. The number and spacing of the rings changes as you range in and out.
... Using the cursor
To measure the bearing and range from your boat to a specified target, move the
cursor to the appropriate position on the screen.
Note:
If cursor data is not shown, refer to page 259.
