3D VARIVIEW™
When the X-70A 3D is first turned on, the 3D screen scrolls from right to
left as shown above. This view shows you the bottom contour as if your
boat is travelling from the left side of the screen to the right side. The
upper right corner of the screen is the right (starboard) side of your boat’s
transom. There are occasions when you may wish to change the viewing
angle of the bottom. For example, if you’re travelling parallel to a drop-off,
the far side of the drop-off may not be visible, due to the higher ground
obstructing the drop-off. By rotating the 3D view, the opposite side of the
drop-off can be seen.
To change the 3D view, first
press the WINDOWS key. The
screen shown at right appears.
There are four views available.
Press the arrow keys to rotate
the 3D view. When you’ve ro-
tated the display to the desired
view, press the CLR key to re-
turn to the 3D screen.
