StructureScan™ | NSS Operator Manual

DownScan image

When zooming in on a DownScan image, the sea ﬂ oor will be kept near to bottom of the

screen, irrespective of whether it is in auto-range or manual range.

If the range is set considerably less than the actual depth, the unit will not be able to ﬁ nd the

bottom when zooming.

If the cursor is active, the unit will zoom in where the cursor is pointed.

SideScan image

Zooming on a SideScan image acts as for DownScan, except that it zooms on the surface

rather than trying to keep the sea ﬂ oor in view.

When the cursor is active, it will zoom where the cursor is pointed.

Adjusting the color settings

Strong and weak echo signals have diﬀ erent colors to indicate

the diﬀ erent signal strengths. The colors used depend on

which palette you select.

The more you increase the Color setting, the more echoes will

be displayed in the color at the strong return end of the scale.

Color is adjustable by using the rotary knob. When you press

the knob the color control image will expand and display

it’s name in full. You can then adjust the value by turning

the knob. If no adjustments are made within 3 seconds the

control will return to default size.

Using the cursor on the StructureScan™ panel

The cursor is by default not shown on the StructureScan

image.

When you tap the screen the cursor will appear. The left/

right distance from the vessel to the cursor are shown at the

cursor position, and the information window and the history

bar will be activated.

To remove the cursor and cursor elements from the panel,

press the Clear cursor panel key or the

X key.

Viewing StructureScan history

Whenever the cursor is active on a StructureScan panel, the red scroll bar is also shown. The

scroll bar shows the image you are currently viewing in relation to the total StructureScan

image history stored.

Depending of the view selected, the scroll bar is on the far right side (DownScan) or at the

bottom of the screen (SideScan).

You can pan the image history by dragging up/down (SideScan) or left/right DownScan.

To resume normal StructureScan scrolling, tap the Clear cursor panel button or press the

key.

Placing a mark on a StructureScan™ image

You can position a mark at the vessel’s position by pressing and holding the MENU key.

You can position a mark on a selected echosounder item by tapping the screen and then

activating the menu.

 Note: Only marks positioned by using the cursor will include depth information.
