Surface Clarity
The markings extending downward from the top of the chart are called
surface clutter. These markings are caused by wave action, boat wakes,
temperature inversion and more.
Surface clarity reduces or eliminates surface clutter from the display. It
does this by changing the sensitivity of the receiver, decreasing it near
the surface and gradually increasing it as depth increases.
There are three levels of surface clarity available: low, medium, or high.
The default level is off.
To adjust the Surface Clarity level:
1. From the Sonar Page, press
MENU|↓ to SONAR FEATURES|ENT.
Sonar Features menu with Surface Clarity.
2. Highlight SURFACE CLARITY and press ENT|↓ or ↑ to select the desired
surface clarity level|
