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 or 455 kHz Sensitivity) which 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™ Menu.

2. Press the RIGHT or LEFT Cursor keys to increase or decrease the

Sensitivity setting. (Low = 1, High = 20, Default = 10)
