REAL TIME SONAR (RTS®) WINDOW

RTS® Window sets the RTS® Window to either Wide or Narrow, or turns it off in the Sonar View. The RTS® Window always updates at the fastest rate possible and only displays returns that are within the transducer beam. (See Getting Started - Using Your 900 Series™: Real Time Sonar [RTS®] Window for more information.)

BOTTOM VIEW

Bottom View selects the method used to represent bottom and structure on the display. Structure ID® represents weak returns in blue and strong returns in red. WhiteLine® highlights the strongest sonar returns in white resulting in a distinctive outline. This has the benefit of clearly defining the bottom on the display. See Bottom Presentation for more information.
