Understanding the Fishfinder screen
This chart shows all the information that your Fishfinder display during the operation. The
upcoming sonar information will firstly appears in the Real-time sonar window, and then
scrolls across the screen from right to left. So, what you see on the screen (Fish symbols,
Fish arches, bottom shape, etc) is formed by the sonar history.
The black line at the top of the screen represents the water surface, and the water depth
and Temp will appear at the upper left corner as soon as you turn on the sonar unit and the
transducer was properly connected.
By moving the transducer slowly at a steady speed, you could see the bottom shape
shown at the bottom of the screen.
Real Time Sonar Window
The plot on the screen demonstrates the sonar history, which varies at different
time segment. So, considering the boat and targets may continually move
when the sonar works, the information displayed on the screen only shows the
time segment when the targets were detected.
To understand the display correctly, you could imagine dividing the screen into
many parallel “bands” at vertical direction. Each “band” represents the signals
received by the sonar unit at a particular time. The closer the position of “brand”
to the right side is, the latest signal it represents.
The Real Time Sonar Window shows the instant time segment when the
targets are detected. With the Real Time Sonar window, you could observe the
fastest updating which will show you the instant underwater information,
including depth, bottom, structure, and fish being detected.
