SONAR
Sensitivity
Sensitivity determines how echoes will be displayed on the screen.
Increasing the sensitivity will make you see more details on the screen. In such situations
when you see too much clutter on the screen, decreasing the sensitivity will play an effect.
The larger the sensitivity is, the more relatively strong sonar returns the screen will display.
If the sensitivity is decreased too low, most sonar returns (which maybe fish) will not be
displayed.
In situation where water is clear or very deep, try increasing the sensitivity, which will let
you see even the very weak returns. However in situation while water is turbid, try
decreasing the sensitivity, which will make only the useful echo be showed on the screen
and the noise will be omitted.
