Real Time Sonar (RTS ™ ) Window
A Real Time Sonar (RTS ™ ) Window appears on the right side of the display in
the Sonar View only. The RTS Window ™ updates at the fastest rate possible for
depth conditions and shows only the returns from the bottom, structure, and
fish that are within the transducer beam. The RTS Window
™ plots the depth
and intensity of a sonar return (see Sonar Menu Tab: RTS Window ™ ).
The Narrow RTS Window ™
indicates the sonar intensity
through the use of colors. Red
indicates a strong return and
blue indicates a weak return.
The depth of the sonar return
is indicated by the vertical
placement of the return on the
display depth scale.
The Wide RTS Window ™
indicates the sonar intensity
through the use of a bar
graph. The length of the
plotted return indicates
whether the return is weak or
strong. The depth of the sonar
return is indicated by the
vertical placement of the
return on the display depth
scale. The Wide RTS
Window
™ does not use
grayscale.
