Sensitivity controls the unit's ability to pick up echoes. 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 ech-

oes, if fish are present. As you change the sensitivity setting, you can 

see the difference on the chart as it scrolls.
