Fig. 2.1 - The Fish Finder page
The following is a short description of terms listed in the previous Fig. 2.1:
Warning Message
Flashing label "Simulation" when the echo sounder is in Simulation mode.
Echogram window
Graphic presentation of sonar soundings recorded as a continuous profile
scrolling across the screen from right to left. Such recordings represent the
image of the water beneath your boat, items appear as they pass under your
transducer; the items on the right side of the screen are closer to you than
those on the left. The correct interpretation of the Echogram allows retrieving
useful information about what is under the boat. See the following Par. 2.1.1
for more information.
Color Bar
Colored scale located on the left side of the screen that shows the colors used
in the Echogram to represent the echoes strength. The color on the top of the
bar represents the maximum sonar strength, while the color on the bottom of
the bar represents the minimum sonar strength.
