13.8 Enhance the vertical scale
You can increase the vertical scale if you want to emphasize the contours of the

5.0 is the default.
To enhance the contours:

2. The
Vertical Scale button shows the current setting. Select the
button if you want to change the setting and a slider box appears.
3. The current setting is shown as a number and as a line within a solid
bar of color. Drag the line, or use the rotary knob to change the setting,
then select OK.
4. The new setting is applied immediately and stays until you change it
again.
13.9 Change the vessel mode
You can choose to display the 3D Chart screen as if you are viewing it from the

vessel.

screen to show your vessel.
To change the vessel mode:
1. Display the 3D Chart screen and control panel. If you can't see the
Show Vessel Mode button, select Settings.
2. The

13.10 Show/hide the bathymetric data
You can toggle the bathymetric data On or Off on your 3D Chart screen.
If the bathymetric data is toggled On and you are:
•
in shallow water, the different depths are shown in different colors and similar
depths are linked by lines. (These lines do not correlate with depth contours
on a chart.)
•
in deep water, the different depths are shown in different colors but there is
no line overlay.
To change the bathymetric setting:
1. Display the 3D Chart screen and the control panel. If you can't see the
Bathymetric button, select Settings.
