cyan; the
Towfish Altitude
display in the Information Window will also change to
cyan; and a display with a cyan background will appear in the Sonar Viewer
window tool bar indicating either "Manual Altitude" followed by the altitude for
the
Use Manual Setting
option or "Offset Altitude" followed by the altitude for the
Use Altitude from Towfish plus Manual Offset
option:
An example of the Sonar Viewer window with the manual altitude tracking
