41Compass PageThe GPSMAP 178C Sounder features two different navigation pages: Compass and Highway. When-ever a NAV goto, Follow Track (TracBack), or Follow Route have been activated, the GPSMAP 178CSounder’s Compass Page guides you to your destination with digital readouts and a graphic compassdisplay, which includes a bearing pointer. Use this page (instead of the Highway Page) when your desiredpath may be varied in direction. The middle of the page features a rotating ‘compass ring’ that shows yourcourse over ground (track) while you’re moving. Your present course over ground is indicated at the topof the compass ring. A bearing pointer arrow, in the middle of the compass ring, and a bearing ‘bug’ indi-cator on the outside of the compass ring, indicate the direction of the destination (bearing) relative to thecourse over ground. The compass ring and pointer arrow work independently to show—at a glance—thedirection 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 thearrow until it points up, then continue in that direction.The bearing pointer, bearing bug and/or compass ring may point in various directionswhen you are stationary or at very low speeds. Once you start moving, the pointer iscorrect.The GPSMAP 178C’s Compass Page features a menu page that provides access to layout and datafi eld options.
