Introduction to Navigation
Use your Fishing System to establish waypoints at areas of interest and to
navigate to those waypoints via a savable route (representing the shortest
intended distance between waypoints). You can also view and save tracks,
which represent the actual path of the boat.
Waypoints, Routes and Tracks
Waypoints are stored positions that allow you to mark areas of interest or
navigation points. Your Fishing System 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 700 Series™ Fishing
System can store up to 50 routes that can each contain up to 50 waypoints.
