Pausing Structurescan; Using The Cursor On The Structurescan Panel - Simrad NSO Operation Manual

Pausing StructureScan

You can pause the StructureScan, allowing you to examine the structures and other
images in more depth and detail.
This function is useful when you need to position a waypoint exactly on the
Structurescan image, and if you are using the cursor to measure a distance between 2
elements on the image.

Using the cursor on the StructureScan panel

The cursor is by default not shown on the StructureScan image.
When you press one of the arrow keys the cursor will be
visible, the depth at the cursor position will be shown, the
information window and the history bar will be activated.
You use the arrow keys to move the cursor in any direction
on the display.
To remove the cursor and cursor elements from the panel,
press the X key.
Using the cursor to position a waypoint
You can position a waypoint at the cursor position by pressing
the PLOT key as described in the Waypoints, routes and
tracks section.
When the key is pressed the waypoint symbol and ID are
positioned at the cursor position.
Measuring distance
The cursor can be used to measure the distance between two observations on the
StructureScan image. It is easier to use the measure function when the sounder image is
paused.
Use the following process to measure a distance:
1
2
3
You can reset the measurement by pressing the Tick key.
When you press the X key the echosounder will resume to normal scrolling.
Viewing StructureScan history
Whenever the cursor is shown 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)— all indicates that you are viewing the latest
soundings.
If you move the cursor to the left side of the screen (DownScan mode) the history
bar will start scrolling towards left, and the automatic scrolling as new soundings are
received will be turned off. If you move the cursor upwards (in SideScan mode) the
history bar will start scrolling upwards, and the automatic scrolling as new soundings are
received will be turned off.
To resume StructureScan scrolling, move the cursor until the red history bar reaches
either the right side of the image (DownScan) or bottom of the image (SidenScan), or
press the X key.
