Sensitivity & Auto Sensitivity
Sensitivity controls the ability of the unit to pick up echoes. A low sensitivity level (from zero to 50 percent) excludes much of the bottom information, fish signals, and other target information.
High sensitivity levels let you see greater detail, but it can also clutter the screen with many undesired signals. Typically, the best sensitivity level shows a solid bottom signal with some surface clutter.
Automatic Sensitivity
The default sensitivity mode is automatic. The unit bases the sensitivity level on water depth and conditions. When the unit is in automatic mode, sensitivity is automatically adjusted to keep a solid bottom signal displayed. This gives it the capability to show fish and other detail.
There are situations when it becomes necessary to increase or decrease sensitivity. This typically happens when you want to see more detail, which requires a boost in sensitivity. But, when wave action and boat wakes clutter the screen with tiny air bubbles, a decrease in sensitivity is necessary.
The control bar used to adjust sensitivity up or down is the same whether the unit is in the automatic or manual mode. In automatic you can adjust sensitivity up to 100 percent but the unit will limit your minimum setting. The unit will continue to make small adjustments, allowing for the setting you selected.
In manual mode, you have complete control over sensitivity with the ability to set it anywhere from zero to 100 percent. Once you select a level in manual mode, the unit will continue to use that exact sensitivity setting until you change it or revert to auto mode.
To adjust sensitivity in auto mode:
1.Press MENUENT.
2.The Sensitivity Control Bar appears. Press ↓ to decrease sensitivity; press ↑ to increase sensitivity. When it's set at the desired level, press EXIT. (When you reach the maximum or minimum limit, a tone sounds.)
