Choosing the
cross-track scale
You can set the
CROSS-TRACK FULL SCALE
option to suit your
particular needs—whether you’re navigating out in open water
or trying to maneuver in a tight channel. Cross-track scale is
the total left-to-right distance shown on the
STEERING
and
3D
STEER
screens. For example, a cross-track full scale setting of
1,000 feet displays 500 feet on either side of your track line.
When setting the cross-track full scale, your choices depend
on the distance and speed units that you’ve set on the
DISPLAY OPTIONS
screen. The relationship between the
distance and speed units and the cross-track scale setting is
described in the table below. (To change the distance and
speed units, see ”Changing your display settings” starting on
page 164.)
To change the cross track full scale setting, on the
NAVIGATION OPTIONS
screen, choose the
CROSS TRACK
FULL SCALE
option and press the
EDIT
menu key. Press the
CURSOR PAD
to see the choices, then press the
ENTER
key to
make your selection.
Changing the
steering precision
The
STEER DIST PRECISION
option adds precision to the
distance-to-waypoint and cross-track error displays on the
STEERING
and
3-D STEER
screens. For example, using the
“normal” setting will display the distance-to-waypoint in
hundredths of miles or kilometers. However, if you change the
setting to “high,” the distance-to-waypoint and cross-track
error are displayed in feet or meters—when you’re under one
mile or kilometer from the destination waypoint.
