Humminbird GR16 - Manual (Page 15)

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.
