Creating and Navigating Routes
The last form of navigating to a destination with
the GPS 125 Sounder is by creating a user-defined
route. The route navigation feature lets you plan and
navigate a course from one place to another using a set
of pre-defined waypoints. Routes are often used when
it’s not practical, safe, or possible to navigate a direct
course to a particular destination (e.g., through a body
of water or impassable terrain).
Routes are broken down and navigated in smaller
segments called “legs”. The waypoint you are going to
in a leg is called the “active to” waypoint, and the way-
point immediately behind you is called the “active
from” waypoint. The line between the “active to” and
the “active from” waypoint is called the “active leg”.
Whenever you activate a route with the GPS 125
Sounder, it will automatically select the route leg clos-
est to your position as the active leg. As you pass each
waypoint in the route, the receiver will automatically
sequence and select the next waypoint as the “active to”
waypoint.
