Sensitivity Setting

The sensitivity adjusts the ability of the unit to tell the differences between

echoes of different strengths. In general, the sensitivity should be as high

as possible, to detect the fish and show the detail on the bottom. How-

ever, if the sensitivity is too high, the unit will begin to see bubbles in the

water, debris, and other “background noise.” Use a higher sensitivity

setting for deeper water, and a lower setting for shallower water.

If you adjust the sensitivity while you are looking at the Sidelooker display,

this will affect the sensitivity for the Sidelooker feature only.

From the menu item for the range setting, press the

arrow on the Page

control pad. The next menu item will allow you to set the sensitivity. See

Fig. 4-3. Use the < and > arrows on the Page control pad to select Auto or

Manual sensitivity.

Auto sensitivity

The FishFinder can be set to select the sensitivity by itself,

automatically. The unit chooses the sensitivity setting

which will detect fish, but will also show a minimum of

background noise. If the amount of background noise

changes (due to changing depth or water conditions), the

FishFinder will change the sensitivity to adjust. (You can

adjust the sensitivity of the unit while it is using Auto

sensitivity. Once Auto sensitivity is selected, use

the

arrow on the Page control pad to go to the next line,

then use the < and > arrows on the Page control pad to

fine-tune the setting. When the FishFinder is turned off,

then on again, the Auto sensitivity setting will return to the

normal or default setting.)
