As the boat moves, the unit charts the changes in depth on the display to create a profile of the bottom contour. The
2D Sonar View displays the sonar return intensity with different colors.
Strong returns often result from rocky or hard bottoms (compacted sediment, rocks, fallen trees), while weaker returns often result
from soft bottoms (sand, mud), vegetation, and small fish.
The colors used to represent high, medium, to low intensity returns are determined by the palette you choose in the Preferences
menu (see Open the 2D Sonar Preferences Menu: Change the Palette and Background).
The control head displays the return intensity based on the Palette and Bottom View menu settings. You can display the RTS Window
(Real Time Sonar), turn on/off fish symbols (Fish ID+), change the SwitchFire mode, adjust sensitivity, and more.
