Used to change the sonar data colour palettes for the sonar images. The 852-GS uses a colour table to
re
present echo data strength (amplitude). For example, the “Normal High” intensity colour table maps the echo
data amplitude to 256 colours ranging from black (low strength level) through blue, green, orange, yellow,
white, and red (highest strength level).
