Sensitivity
Sensitivity adjusts the way echoes are displayed on the screen. If you
want to see more detail, try increasing the sensitivity, a little at a time.
When there is too much clutter on the screen, decrease sensitivity to
reduce the clutter and show the strongest fish echoes, if fish are pres-
ent. As you change the sensitivity setting, you can see the difference on
the chart as it scrolls.
