Optimizing the StructureScan Image
Several parameters can be adjusted to optimize the StructureScan image.
Color
The strength of the echo is symbolized by colors. A strong
return will be shown with a reddish-brown color, while a weak
signal will be light blue (depending on which palette you select).
The more you increase the color, the more echoes will be
displayed as reddish-brown.
Adjusting the color settings
Color is adjustable by using the rotary knob.
The active control 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 controls will return
to default size.
Noise rejection
StructureScan signal interference from bilge pumps, engine vibration
and air bubbles can clutter the StructureScan image.
The noise rejection option filters the impact of StructureScan signal
interference by reducing the on-screen clutter.
Flip left/Right function
This function controls the orientation of both StructureScan functions:
SideScan and DownScan.
If your transducer is installed with the cable end pointing away from
the back of your vessel; the Flip left/right function will ensure that
what is on the left or right side of your vessel matches what is on your
display.
Clarity
Wave action, boat wakes and temperature inversion can cause on-screen clutter near the
surface.
The surface clarity option reduces surface clutter by decreasing the sensitivity of the
receiver near the surface.
