958 Operator's Manual, Rev. A
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.)

If... you choose KM/KPH
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.
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.
