The Sidelooker Page

The Sidelooker page, like the Standard page, displays a graph or chart.
As new echoes are received by the Sidelooker transducer, the chart
scrolls from the top to the bottom of the display. The display is divided by
a boat symbol and centerline indicator. The line at the center of the
display represents the centerline of the boat. The new information
appears at the top of the display. Older information moves towards the
bottom. The display scrolls from top to bottom, but this does not
necessarily happen at the same speed the boat is moving. (The speed
at which the display moves is set by the Soft Key for Chart Speed. To
reach this Soft Key, press the Menu button.)
The Sidelooker transducer transmits at the 200kHz frequency. The unit
presents different kinds of information, depending on whether the "fish
symbol" feature is turned on or off.
If the fish symbols are turned off -
Fish echoes appear as vertical arches. This setting allows the unit to
display underwater objects such as shorelines, river banks, piers,
submerged tree stumps or rocks.
