Pointer to Wajipoini

The line down the middle of the graphic high­

way represents your desired track (a straight line

between the position you started from to the

selected waypoint), with your present position

indicated hy the diamond in the center of the

course devition scale. The arrow pointer below the

highway serves as a relative bearing pointer to

your destination waypoint.

As you navigate toward a waypoint, the high­

way will actually move, indicating the direction

you’re off course, relative to the position diamond

on the GDI scale. To keep your vessel on the

desired course, simply steer toward the center of

the hi^way.

If you do get off the desired course by more

than l/5th of the selected GDI range, the exact

distance you are off course will be displayed where

the GDI scale setting normally appears (see the

example at left). As you approach a waypoint, a

horizontal ‘finish line’ will move toward the bot­

tom of the highway. When the finish line reaches

the GDI scale, you’ve arrived at your destination.
