Sonar X-Press™ Menu
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.
To 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)
Sensitivity at Medium Sensitivity at High Sensitivity at Low
