Now that we’re navigating to an actual destination, let’s move on to the GPSMAP 188/188C/238
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
rotating ‘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.
The current speed, distance to the next waypoint, turn angle, and current position are displayed at
the top of the screen. This page provides better steering guidance when travelling at slower speeds and/
or when making frequent directional changes. When you are not navigating to a waypoint, the compass
will show your direction of travel as you move but the arrow will not appear.
Numbers Page
Press PAGE to see the next page appearing in the main sequence, the Numbers Page. The
Numbers Page allows for precision navigation to 1 degree of steerage. The default page displays 3 large
numbers fi elds. You may customize the Numbers Page to display the size and number of fi elds along
with the type data you wish to see. (See pages 26-28 for changing the types of data.)
