Chart Speed
Chart Speed determines the speed at which
the sonar information moves across the display, and consequently the
amount of detail shown. A faster speed shows more information in the Sonar
Views and is preferred by most anglers; however, the sonar information
moves across the display quickly. A slower speed keeps the information on
the display longer, but the bottom and fish details become compressed and
may be difficult to interpret. Regardless of the Chart Speed setting, the RTS®
Window will update at the maximum rate possible for the depth conditions.
Adjust Chart Speed to your personal preference.
To adjust the Chart Speed:
1. Highlight Chart Speed on the Sonar X-Press™ Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or
decrease the Chart Speed setting. (1-10, where 1 = Slowest, 10 =
Fastest, Default = 5)
Quad Layout
(with optional-purchase QuadraBeam PLUS™
Transducer, Side Beam View only)
Quad Layout selects the method used to represent the sonar information
from the two side-looking beams plus the down-looking beam to be
presented on the Side Beam View, and is only available when an optional-
purchase QuadraBeam PLUS™ transducer is attached and the Side Beam
View is active. Use Quad Layout to change the way the Side Beam View is
displayed. See
Side Beam View for more information.
To adjust the Quad Layout:
1. Highlight Quad Layout on the Sonar X-Press™ menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Quad
Layout setting for the Side Beam View. (Default, Classic, Slanted,
Default = Default)
