Sensitivity
Sensitivity controls how much detail is shown on 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.
NOTE: The Sensitivity setting is a global setting and will adjust the sensitivity of all sonar
frequencies, as compared to specific sensitivity adjustments (such as 83 kHz Sensitivity, 455 kHz
Balance or Wideside Sensitivity) that allow you to adjust the level of sensitivity for one specific
beam at a time.
To adjust the Sensitivity:
1. Highlight Sensitivity on the Sonar X-Press
TM
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 Low Sensitivity at Medium Sensitivity at High
