Choosing The Colours Used To Present The Echograms - Simrad ES80 Reference Manual

Choosing the colours used to present the echograms

Several different colour scales are predefined and available for the presentation of
echograms. You can easily choose which colours to use. The presentation colours have
no effect on the operational performance of the ES80. The
controls the presentation colours used by the ES80. This includes the palette ("skin"), the
number of colours in use, and the colour scale.
Context
Which colour scale to use is mainly a personal preference based on ambient light
conditions, the nature of the echoes and your own experience.
Keep in mind that in the basic scale with 12 colours, each discrete colour represents a
3 dB range of echo signal strength. This implies that the next colour is selected every
time the echo strength is doubled.
Tip
By default you have 64 or 12 colours available to present the echoes, and a selection of
palettes. The colour scale can be retrieved any time by selecting
bar. The chosen colours are shown at the bottom of the ES80 presentation.
If you choose to use many colours, the resolution of the ES80 presentation is greatly
improved. It is then easier to distinguish the difference between the various echoes of
different size and/or target strength.
