Setting Up the StructureScan Display
The StructureScan panel can be setup with different views; either as a single view (Left
Only, Right Only or Down), or double view (Left + Right) this view presents the left and
right side of your vessel underwater.
SideScan
Enables you to view the structure and terrain without having to navigate your vessel over
the top of your destined course. It has high-resolution detail with 152 m side-to-side
underwater views. It is designed to cover more water in less time; and provide views
in both the left and right sides under your vessel, using the water column in centre of
display.
DownScan
Broadcasts a beam downwards that displays a high-detail sonar image scanning focused
down below your vessel. It provides you with the same high resolution that is displayed
from right to left of display panel.
Zoom
You can select different zooming levels on the StructureScan image.
By default the zoom level is set to Off.
Setting StructureScan range
The range setting determines the depth shown on the display.
Auto
If you select Auto, the system will automatically display the whole range from the water
surface to the bottom. Auto range will automatically be turned off once you adjust the
range manually.
Manually changing the range
You can increase or decrease the range by pressing the zoom keys.
Pressing and holding one of the zoom keys will toggle between auto and manual range.
Autorange is resumed by pressing the “0” key.
When manually changing the range the lower depth line will be moved upwards or
downwards. The upper depth line will always be at the water surface.
This options allows you to focus on echoes at the upper part of the water column.
The StructureScan frequency
Structurescan supports transducer two frequencies. 455kHZ is ideal for greater depth
and distance and 800kHZ provides better definition.
