Settings

Surface Clarity

Wave action, boat wakes and temperature inversion are some of the sources that can cause onscreen clutter near the surface. Surface Clarity reduces surface clutter by decreasing the sensitivity of the receiver near the surface.

To adjust Surface Clarity:

1. Select Surface Clarity from the	Surface Clutter
Sonar Settings menu and press
ENTER.

2. Use the keypad to choose the desired option.

Scroll Speed

Controls how fast the sonar chart scrolls across the screen. A slower scroll speed is best suited for ice fishing or fishing while at anchor. It is also useful when you want

to record a higher quality sonar log in deep water. By default, Scroll Speed is set to normal.

To make adjustments, select Scroll Speed from the Sonar Settings menu and use the keypad to make adjustments.

Manual Mode

Advanced user mode that bypasses digital depth to give you greater control of ping settings. Digital depth causes the unit to search for the bottom regardless of the portion of the water column you are targeting. While you still will get good results using digital depth, it prevents you from getting optimum performance in certain situations, like fishing for suspended targets.

In Manual Mode the unit sends sonar signals (pings) only to the depth range you select. Adjustments made to the range setting will be reflected in your unit’s ping speed. That makes it easy to get the best scrolling speed and the best screen resolution for a selected range.

Select Manual Mode from the Sonar Settings menu and press ENTER to turn on/ off Manual Mode.
