Sensitivity
Sensitivity adjusts the way echoes will be displayed on the screen. If
you want to see more detail, try increasing the sensitivity, a little at a
time. There are situations when too much clutter appears on the
screen. Decreasing the sensitivity can reduce the clutter and show the
strongest fish echoes, if fish are present. As you change the sensitivity
setting, you can see the difference on the chart as it scrolls.
Sensitivity set to manual mode (left). Sensitivity scroll bar (right).
You can change the sensitivity level whether you are in Auto Sensitivity
mode or Manual Sensitivity mode. The adjustment method works the
same in both modes, but gives you slightly different results.
