Sensitivity
Settings: 0 - 10; Default = 5, Setting Saved in Memory
Sensitivity controls how much detail is shown on the display.
Increasing the sensitivity shows more sonar returns from small baitfish and
suspended debris in the water; however, the display may become too
cluttered. When operating in very clear water or greater depths, increased
sensitivity shows weaker returns that may be of interest.
Decreasing the sensitivity eliminates the clutter from the display that is
sometimes present in murky or muddy water. If Sensitivity is adjusted too low,
the display may not show many sonar returns that could be fish.
