Using Structure Palettes
Several display structure templates with varying degrees of
color and brightness are available.
Using the Cursor on the StructureScan
Panel
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.
Viewing StructureScan history
Whenever the cursor is shown on a StructureScan panel, the
green 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 either DownScan or SideScan modes— when 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.
Therefore, 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. Conversely, 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 green history bar reaches
either the right side of the image (DownScan) or bottom of the image (SidenScan), or
press the ‘X’ key.
Measuring distance
The cursor can be used to measure the distance between the position of 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:
Move the cursor to the fi rst measuring point 1
Start the Measure function 2
Move the cursor towards the second measuring 3
point
A line will be drawn from the first point to the
-
cursor, and the distance will be listed in the
Information window
You can reset the measurement by pressing the Tick key.
When you press the ‘X’ key the echosounder will resume
to normal scrolling.
