Sensitivity
Controls the sensitivity of the FishReveal data. Increasing sensitivity
shows more detail on the screen. Decreasing sensitivity displays less.
Too much detail clutters the screen. If the sensitivity is set too low,
weak fish arch data might not be displayed.
Colorline
Adjusts the colors of the fish arch data to help differentiate them
from other targets. Adjusting the colorline can help separate fish
and important structures on or near the bottom from the actual
bottom.
Surface clarity
Wave action, boat wakes and temperature inversions can cause
onscreen clutter near the surface. The surface clarity option reduces
surface clutter by decreasing the sensitivity of the receiver near the
surface.
Palette
Select between several display palettes optimized for a variety of
fishing conditions.
Ú Note:
Palette choice is often a user preference, and may vary
depending on the fishing conditions. It is best to select a
palette that provides good contrast between the image details
and FishReveal arches.
Range lines
Range lines can be added to the image to make it easier to estimate
depth.
Preview
You can have all available sonar history shown at the top of the
sonar screen. The Preview bar is a snapshot of available sonar
history. You can scroll through sonar history by dragging the
preview slider horizontally. By default, Preview is turned on when
the cursor is active.
