Isolating objects near the bottom

The white line feature separates echoes from objects near the bottom and the
bottom itself. When white line is switched on, the sonar displays echoes
differently.
White
line
The strongest echoes are displayed in the background with a thin line on top. All
other echoes remain unchanged.
To display white line:
1. Select Controls/More.
2. Click
The scrolling bottom image will start to display white line from the right of
the screen.

How do I get a closer view of an image?

Zoom enlarges all or part of the scrolling bottom display. You should select
automatic zoom if you want to keep the bottom in the lower half of the display
page. Alternatively you can select the level of zoom to a factor of x2, x4 or x6,
proportional to the current range. You can also split the sonar image vertically to
show the zoomed area on the left of the screen and the scrolling bottom on the
right of the screen.
White Line
