WAYPOINTS, ROUTES AND TRACKS (987c SI Combo models only)

Waypoints are stored positions that allow you to mark areas of interest or navigation points. Your 900 Series™ can store up to 3000 waypoints.

Routes link two or more waypoints together to create a path for navigation, and are used in trip planning. You can link individual waypoints together by using the GOTO key. A route represents your intended navigation and shows the shortest path from each waypoint to the next. As you travel a route, staying on the route line is the most efficient way to get to your destination, although you should always look out for obstacles not shown on the chart. Your 900 Series™ can store up to 50 routes that can each contain up to 50 waypoints.

Tracks consist of detailed position history, and are displayed as a breadcrumb trail of trackpoints. The Current Track shows the position history since the unit was powered up (maximum of 20,000 trackpoints displayed). You can clear the Current Track or save it at any time. Your 900 Series™ can store up to 50 saved tracks, each containing 20,000 trackpoints. The current track represents your actual path so far.

SAVE, EDIT, OR DELETE A WAYPOINT (987c SI Combo models only)

Save your current position as a waypoint: On any view, press the MARK key to save the current position of the boat as a waypoint.

Save the cursor position as a waypoint: On the Chart or Combo view, use the Cursor key to designate the position you want to save as a waypoint. Then press the MARK key to save the marked position as a waypoint.

Save a position from the sonar history: On the Sonar view, use the Cursor key to point to a feature in the sonar history (also called the Sonar Saver feature). Press the MARK key to create a waypoint at the location where that sonar reading was taken. The new waypoint will also record the depth at that location.

NOTE: When you save a waypoint by any of these methods, a numerical waypoint name is automatically assigned. You can edit the waypoint information later to give it a different name and select an icon to represent it (see Waypoint submenu on the Navigation Main Menu Tab).
