SIDE IMAGING VIEW

Side Imaging View shows a shadowed right- and left-looking view from the boat as the
boat passes over the bottom. See Side Imaging: On the Water Interpretation for more
information about interpreting the Side Imaging view.
In this view, you can change which side you look at, the sensitivity of the sonar to allow
you to see more or less detail, the range of the side beams, the scrolling speed of the
chart, and the color scheme of the display, all from the Side Imaging X-Press™ Menu.
See Side Imaging X-Press™ Menu, as well as Understanding Side Imaging, for more
information.
