Let’s move on to the GPSMAP 178/178C Sounder’s navigation pages by pressing the PAGE key.
Compass Page
The Compass Page provides graphic steering guidance to a destination waypoint, with an emphasis
on the bearing to your destination and current direction of travel. The middle of the page features a rotat-
ing ‘compass ring’ that shows your course over ground (track) while you’re moving, and a bearing pointer
that indicates the direction of the destination (bearing) relative to the course over ground. The compass
ring and pointer arrow work independently to show—at a glance—the direction of your movement
and the direction to your destination. For instance, if the arrow points up, you are going directly to the
waypoint. If the arrow points any direction other than up, turn toward the arrow until it points up—then
continue in that direction. Bacause the compass rings uses GPS technology, you must be moving in order
for the track to display properly.
The current speed, distance to the next waypoint, turn angle, and time to the next waypoint display
at the top of the screen. When you are not navigating to a waypoint, the compass shows your direction of
travel as you move, but the arrow does not appear.
The Compass Page allows for precision navigation to one degree of steerage. The default page
displays one row of medium numbers fields. You may customize the Compass Page to display the size
and number of fields along with the type data you wish to see. (See pages
30-31 for changing the types of
data.)
