Humminbird Wide 3D manual Menu Functions, Sensitivity

MENU brings a menu on-screen for adjustment, or if a menu is already present, the next menu in sequence will appear. Menus will go off-screen and normal operation will resume after a short period of time. If you wish to keep the menu on-screen for an extended period of time, press STOP.

UP arrow selects the next larger or next sequential adjustment within the menu. Holding an Arrow button down will cause the unit to continue to make the adjustment, until a limit is reached, and the limit alarm sounds.

DOWN arrow selects the next smaller adjustment within the menu.

ENTER is used to toggle other menu options on and off.

All menus use the same general layout as shown in the sample menu. The heading of the menu is at the top. The area in the center is controlled by the UP and DOWN arrows, and the area under the horizontal line is controlled by the ENTER button. Not all menus are affected by all controls, but the layout is the same regardless. Pressing MENU repeatedly will sequentially display all available menus.

MENU FUNCTIONS

The following section explains each menu in detail, and how these adjustments can be used to extract the maximum information from the sonar returns. With several exceptions, once a setting has been changed, the Wide 3D View will remember that setting until it is again changed, even if power is disconnected.

SENSITIVITY

As the Wide 3D View receives returned signals, the sensitivity of the receiver is adjusted automatically based on a number of factors such as the depth of the water, and the signal clarity. In murky water, full of debris, the Wide 3D View will select a lower sensitivity setting. In clear water, where there is little debris to defract the sonar signal, the sensitivity is set higher.

The sensitivity menu allows you to “bias” this automatic setting up or down based on personal preference.

You can select a bias of +5 to –5, for 11 different bias settings. A bias setting of “0” has no effect on the automatic function. A +3 setting selects a sensitivity setting three steps higher than the unit would normally select, so even the smallest returns are displayed on- screen.
