Humminbird 1197C SI Fish Finder User Manual


 
Sensitivity
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.
T
o adjust the Sensitivity:
1. Highlight Sensitivity on the Sonar X-Press™ menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase
or decrease the Sensitivity setting. (Low = 1, High = 20,
Default = 10)
