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.)
