Color Threshold
The Color Threshold dialog box allows the user to adjust the
color table for the echo sounder and vertical sonar windows
individually. Note that the sonar return data is not
compromised and is recorded to file independent of the
color thresholding. Thus on file playback, the threshold may
be altered according to need.
Detection Threshold: This adjusts the point at which data
is displayed. All sonar data values below the detection
threshold show as black.
Saturation Threshold: This adjusts the point at which data
is displayed as red. All sonar data values above the
saturation threshold show as red.
Data Value < Detection Threshold = Display as Black
Detection Threshold < Data Value < Saturation Threshold
Datavalue *107
Datavalue = ---------------------

Data Value > Saturation Threshold = Display as Red
