To adjust the Bottom View:

1.Highlight Bottom View on the Sonar X-PressTMMenu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom View setting. (Inverse, Structure ID®, WhiteLine®, Bottom Black, Default = Inverse)

Zoom Level

(Sonar Zoom View only)

Zoom Level sets the magnification level for the Sonar Zoom View, and is only available on the X-PressTMMenu when the Sonar Zoom View is active. Use Zoom to increase the display resolution to separate sonar returns that are very close together.

To adjust the Zoom Level:

1.Highlight Zoom Level on the Sonar X-PressTMMenu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Zoom Level setting for the Sonar Zoom View. (2x, 4x, 6x, 8x, Default = 2x)

NOTE: The Zoom Preview Box tracks the bottom and cannot be moved by the user.

Bottom Lock

(Sonar Zoom View only)

Bottom Lock changes the mode of the Zoomed view in the Sonar Zoom View. Bottom Lock continuously graphs the bottom at a constant point on the display regardless of changes in depth. This "flattens" out the bottom contour, but is effective at showing fish on or near the bottom.

To turn on Bottom Lock:

1.In the Sonar Zoom View, highlight Bottom Lock on the Sonar X-Press™ Menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom Lock setting to on. (Off, On, Default = Off)

Bottom Range

(Sonar Zoom View only, when Bottom Lock is On)

Bottom Range allows you to control how much of the water column, measured up from the bottom, is shown in the Sonar Zoom View. Choose a small value to see low- lying bottom structure or details of the bottom return. Choose a larger value to see large structure in deeper water. It is possible to set the Bottom Range to be greater than the depth. In this case, you may see surface clutter in a wavy band that mirrors changes in the depth.

To adjust the Bottom Range:

1.In the Sonar Zoom View, highlight Bottom Lock on the Sonar X-Press™ Menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom Lock setting to on. (Off, On, Default = Off).

3.Once you turn on Bottom Lock, the Bottom Range X-Press™ menu choice will be displayed. (10 - 60 feet or 3-20 meters [International Models only], Default = 15 feet)
