UNDERSTAND THE SONAR VIEWS
A
s the boat moves, the unit charts the changes in depth on the display to create a profile of the bottom contour. The
S
onar 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 Sonar Colors
menu (see Customize the Sonar View).
The control head displays the return intensity based on the Sonar Colors 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.
