Bottom Zoom (3D Sonar, 3D/2D Sonar Combo Views Only); Lower Range (3D Sonar, 3D/2D Sonar Combo, 6-Beam Sonar Views Only) - Humminbird 531338-1_C Operation Manual

3D Bottom Zoom provides a magnified image of the bottom, and is only available on the
X-Press™ Menu in the 3D Sonar View and the 3D/2D Sonar Combo View. Use 3D Bottom
Zoom to increase the detail of the bottom on the display.
To adjust the 3D Bottom Zoom:
1. Highlight 3D Bottom Zoom on the Sonar X-Press™ Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the 3D Bottom Zoom
setting. (Off, 1.5x, 2x, 2.5x, 3x, Default = Off)
3D Lower Range sets the deepest depth range that will be displayed, and is only available
on the X-Press™ Menu when you are in the 3D Sonar, 3D/2D Sonar Combo, or the 6-Beam
Sonar View. Automatic is the default setting. When in automatic mode, the lower range
will be adjusted by the unit to follow the bottom. Selecting a specific setting locks the depth
range into Manual mode.
For example, if you are fishing in 60 feet of water but are only interested in the first
30 feet (surface to a depth of 30 feet) you should set the Lower Depth Range limit to
30. The display will show the 0 to 30 foot range, allowing you to see a more detailed
view than you would see if the display went all the way to the bottom.
To adjust the 3D Lower Range:
1. Highlight 3D Lower Range on the Sonar X-Press™ Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Lower
Range setting. (AUTO, 10 to 240 feet, 3 to 75 meters [International Models Only],
Default = AUTO)
