Introduction to Navigation
Use your Fishfinder to establish waypoints at areas of interest and to navigate
to those waypoints via a 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 750 waypoints.
Routes link two or more waypoints together to create a path for navigation, and
are used in trip planning. 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.
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 2000 trackpoints displayed). You can clear the Current
Track or save it at any time. Your Fishing System can store up to 10 saved tracks, each
containing 2000 trackpoints. The current track represents your actual path so far.
