• A-scope – displays a real-time image of the bottom structure and fish
directly below the transducer. The A-scope window also displays the pat-
ented Bottom Coverage width indication.
• Zoom – enlarges all or part of the bottom graph display. You can select x2,
x4 or x6 magnification and the zoom area can be automatically or manu-
ally adjusted.
You can select Zoom, Bottom Lock or A-scope to be vertically split with the
bottom graph display. Alternatively, Zoom or Bottom Lock can be displayed
in place of the bottom graph display.
If you choose dual frequency, the scrolling bottom graph is displayed in both
frequencies, split horizontally. Zoom, Bottom Lock or A-scope can be
displayed with the dual frequency graph.
All of these options are available when the fishfinder is displayed in a half-
screen window.
