Humminbird Wide 3D Vista manual Range

A setting of –2 sets the sensitivity two steps below what the unit would normally select, so only the largest targets of other returns are displayed.

Another use of the Sensitivity menu is to select the bottom representation. In the 2D view the Wide 3D Vista normally displays a variable Structure ID bottom, which can allow experienced users to determine the texture or relative hardness of the bottom. For simplicity, you can select a black bottom using the ENTER button. This blackens in the display below the bottom for easiest recognition of the bottom location, even from a great distance.

RANGE

The Wide 3D Vista adjusts the depth range automatically, so the bottom return is displayed at the bottom 1/3 of the display. This leaves the top 2/3 to display anything between the surface and the bottom. As your boat moves over deeper or shallower water, the unit adjusts the depth range of the display to keep the bottom return in the same general area on the screen.

However, you may choose to control this range adjustment manually. By pressing ENTER, you can select manual operation, meaning the unit will no longer adjust the depth range automatically. The depth range selected is controlled by the UP and DOWN arrow buttons. 3D depth ranges of 0-15 feet, 30 feet, 60 feet, 120 feet, 180 feet, & 240 feet can be selected. In the 2D view depth ranges will be extended and include 360 feet, 480 feet, 600 feet, & 1000 feet. An on-screen icon indicates whether the unit is in “AUTO” (automatic) or MNL (manual) range control.

If you alter the depth range, the unit will switch to manual operation. This feature is valuable if you are only interested in targets near the surface. The Wide

3D Vista will always display the digital depth of the water in the manual mode. If the bottom is not visible in the depth range selected, a 3D grid will be shown for reference.
