Note: The history bar can be turned off. Refer to "Clear live history" on page 89.
Saving waypoints
To save a waypoint, position the cursor on the panel and then select the new waypoint
menu option.
If the cursor is positioned on a 3D image, no depth information is included for the waypoint.
The waypoint on a 3D image is drawn with a line beneath it to indicate its point on the sea
floor.
3D mode options
There are two modes for the 3D panel:
• Vessel mode
• Cursor mode
Switch between vessel mode and cursor mode by selecting the 3D panel buttons. You can
also return from cursor mode to vessel mode by selecting the clear cursor menu option.
3D vessel mode
In this mode, the view is locked to the vessel, and the image moves with the vessel.
The camera can be rotated around the vessel, and the camera elevation changed to look
down or look more sideways from the vessel:
• To change the camera rotation, drag horizontally on the screen
• To change the camera elevation and tilt, drag vertically on the screen
3D cursor mode
When you activate cursor mode, the camera position is the same as when cursor mode was
enabled.
In cursor mode, the image does not move with the vessel. The image can be zoomed, and
the camera can be rotated in any direction by dragging on the screen.
Cursor mode includes the cursor functions described in "Using the cursor on a 3D image" on page 86.
Fish renderings
When objects are identified in the water column, they are shown as clusters of dots. The
point color corresponds to the target intensity, and the point colors are automatically
adjusted to complement the chosen palette.
Viewing image history
The highlighted part of the history bar shows the image you are currently viewing in relation
to the total image history stored.
The history bar appears by default when the cursor is active. You can turn off the history bar,
have it always shown at the top of the screen, or have it appear only when the cursor is
active. Refer to "Clear live history" on page 89.
The history bar is at the top of the screen on 3D images.
You pan the image history by dragging on the image, or by dragging the highlighted region
of the history bar.
To resume scrolling showing current data, clear the cursor.
