can do this on the
Waypoints chart
screen or
any of the waypoint list screens.
To update the waypoint’s coordinates to
your exact position, display the
Edit Waypoint
screen for the waypoint as described
above. When your position is correct, press
Update position
and
ENTER
.
Introducing routes
A route is a sequence of waypoints that you
designate. Routes can be used to perform
the following functions:
•
as guidance through a channel or
harbor
•
as a quick and efficient path to good
fishing spots
•
as the best way around a permanent
obstacle, such as an island
•
as guidance on a single long voyage
with various “legs” to food and fuel
stops along the way, or to other
temporary destinations
Waypoints in a route are connected by
straight lines called
legs. The 972 can
follow route legs in a forward or backward
direction. You can start following a route in
either of two ways:
•
go directly to any waypoint in the
route, then automatically continue on
the next leg (cross-track distance starts
at zero, because you’re on the course
line from your present position to the
waypoint)
•
start along any leg of the route
(cross-track distance starts at your
distance from the leg)
See ”Navigating along routes” beginning on
page 58.
You can create a route in three different
ways:
•
use the
Chart
screen to choose a
sequence of waypoints
•
use a waypoint list to choose a
sequence of waypoints
•
save a route’s waypoints as you travel
Route and waypoint capacity
A route can have up to 35 waypoints. You
can store as many as 500 routes in the 972,
but the maximum number depends on the
number of stored waypoints. Each route
takes up space that otherwise could be
occupied by one or two waypoints.
