selects the width of the window
dedicated to Real Time Sonar. Selecting Narrow
decreases the width of the RTS window leaving
more space for the chart window, however some
sonar returns will not be visible. Selecting Wide makes the RTS window
wider and shows more of the sonar intensity information, however less
space on the LCD is available for sonar history. Selecting Off turns off the
RTS window and the entire LCD shows sonar history.
Note: When the RTS window is adjusted to Wide, no grayscale
information is shown.
RTS Window setting is retained in memory when the 160 is turned off. The

eliminates most sonar returns
near the water surface caused by trapped air,
boat wakes and temperature inversions. Most
surface clutter appears on the display because the
strongest sonar return comes from the shallowest objects. The
160 uses a
sophisticated feature called TVG (Time Variable Gain) to overcome surface
clutter and counteract the affect of depth on sonar return strength. The
level 1 setting is optimal for making sonar information from all depths
appear the same. However, many users prefer to see more surface clutter
than this setting shows. Selecting a higher number shows more surface
clutter, but sonar returns nearest the surface will appear more intense than
they actually are.
The Surface Clutter setting is retained in memory when the 160 is turned
off. The factory setting is 4.

and structure, as well as show fainter sonar
returns more clearly. When a White Line setting
of 1 to 8 is selected, a light gray band highlights the strongest sonar returns
within the sonar image and makes a distinctive outline along the bottom
contour, structure and fish. Selecting a larger numeric setting increases the
width of the band and makes fainter sonar returns more noticeable;
