the display and will adjust the sensitivity of all sonar frequencies. 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.
