View

Settings: Sonar, Track (PiranhaMAX 176i and 196ci only), Status;

Default = Sonar

View selects a view to be displayed on the screen.

Depth Range

Settings: Auto, 15 ft - 600 ft, 5 m - 184 m (International Models only); Default = Auto

Depth Range sets the deepest depth range that will be displayed by the unit.

Auto: When in automatic, the lower range will be adjusted by the unit to follow the bottom.

Manual: You can adjust the Depth Range to lock the unit on a particular depth.

NOTE: In manual operation, if the depth is greater than the depth range setting, the bottom will not be visible on the display. Select AUTO to return to automatic operation.

Sensitivity

Settings: 0 - 10; Default = 5, Setting Saved in Memory

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.
