Setting up the StructureScan image
Range
The range setting determines the water depth that is visible on the screen.
Auto range
When the range is set to Auto the system will automatically set the range depending on the
water depth.
Preset range levels
You can select between several preset range levels.
Custom range
This option allows you to manually set both upper and lower range limits.
The StructureScan panel can be set up as a single view, or with split view where the left and
the right side presents different images.
StructureScan frequencies
StructureScan supports two frequencies. 455 kHz is ideal for greater depth penetration and
while 800 kHz provides better definition especially at shallower depths.
Contrast
The contrast determines the brightness ratio between light and dark areas of the screen. This
makes it easier to distinguish object from the background.
To adjust the contrast setting:
1.
Select the contrast icon or activate the contrast option in the menu
- The color adjustment bar is displayed
2.
Drag the bar or use the rotary knob to set the value
Palettes
You can select between several display palettes optimized for a variety of fishing conditions.
Pausing the StructureScan image
You can pause the StructureScan image, 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.
Advanced StructureScan settings
TVG
The TVG (Time Variable Gain) option compensate for distance to the object, making echoes
from equal sized objects appear with the same size on the echosounder image.
Flipping the Structure image left/right
If required, the left/right SideScanning images can be flipped to match the corresponding
side of you vessel.
Range Lines
Range lines can be added to the image to make it easier to estimate depth (Downscan) and
distance (SideScan).
