Select an option:
• To adjust the scroll speed automatically using speed-over-

ground or water speed data, select 

Auto

.

The Auto setting selects a scroll rate to match the boat 

speed, so targets in the water are drawn with the correct 

aspect ratio and appear less distorted. When viewing 

DownVü or SideVü sonar views, it is recommend to use 

the Auto setting.

• To use a very fast scroll speed, select 

Ultrascroll®

.

The Ultrascroll option quickly scrolls new sonar data, but 

with a reduced image quality. For most situations, the Fast 

option provides a good balance between a quickly 

scrolling image and targets that are less distorted.

Sonar Frequencies

NOTE: 

The frequencies available depend on the transducer 

being used.
Adjusting the frequency helps adapt the sonar for your particular 

goals and the present depth of the water.
Higher frequencies use narrow beam widths, and are better for 

high-speed operation and rough sea conditions. Bottom 

definition and thermocline definition can be better when using a 

higher frequency.
Lower frequencies use wider beam widths, which cover a larger 

area and can let the fisherman see more targets, but could also 

generate more surface noise and reduce bottom signal 

continuity during rough sea conditions. Wider beam widths 

generate larger arches for fish target returns, making them ideal 

for locating fish. Wider beam widths also perform better in deep 

water, because the lower frequency has better deep water 

penetration. They can be used to search for structures such as 

brush piles.

Selecting Frequencies

NOTE: 

You cannot adjust the frequency for all sonar views and 

transducers.
You can indicate which frequencies appear on the sonar screen.

Creating a Frequency Preset

NOTE: 

Not available with all transducers.

You can create a preset to save a specific sonar frequency, 

which allows you to change frequencies quickly.

Turning On the A-Scope

NOTE: 

This feature is not available in all sonar views.

The a-scope is a vertical flasher along the right side of the full-

screen sonar view. This feature expands the most recently 

received sonar data so that it is easier to see. It can also be 

helpful for detecting fish that are close to the bottom.

Depth Line

: Shows a quick-reference depth line.

Scroll Speed

: Sets the rate at which the sonar scrolls from right 

to left.
In shallow water you might want to slow the scroll speed to 

extend the length of time the information is displayed on 

screen. In deeper water you can increase the scroll speed.

Range Lines

: Shows the vertical lines indicating the distance to 

the right and left of the boat. This setting is available for 

SideVü sonar view.

Color Scheme

: Sets the color scheme of the sonar view. This 

setting might be available in the Appearance menu.
The high contrast color schemes provide darker color 

assignments to the low intensity returns. The low contrast 

color schemes provide color assignments to the low intensity 

returns that are similar to the background color.

Appearance

: See 

Sonar Appearance Settings

.

Overlay Numbers

: Sets the data shown on the sonar screen.

Advanced

Advanced Sonar Settings

Installation

: Restores the default sonar settings.

Color Scheme

: Sets the color scheme.

Edge

: Highlights the strongest signal from the bottom to help 

define the hardness or softness of the signal.

A-Scope

: Displays a vertical flasher along the right side of the 

screen that shows instantaneously the range to targets along 

a scale.

Pic. Advance

: Allows the sonar picture to advance faster by 

drawing more than one column of data on the screen for 

each column of sounder data received. This is especially 

helpful when you are using the sounder in deep water, 

because the sonar signal takes longer to travel to the water 

bottom and back to the transducer.
The 1/1 setting draws one column of information on the 

screen per sounder return. The 2/1 setting draws two 

columns of information on the screen per sounder return, and 

so on for the 4/1 and 8/1 settings.

Fish Symbols

: Sets how the sonar interprets suspended 

targets.

Interference

: Adjusts the sensitivity to reduce the effects of 

interference from nearby sources of noise.
The lowest interference setting that achieves the desired 

improvement should be used to remove interference from the 

screen. Correcting installation issues that cause noise is the 

best way to eliminate interference.

Surface Noise

: Hides surface noise to help reduce clutter. 

Wider beam widths (lower frequencies) can show more 

targets, but can generate more surface noise.

Color Gain

: See 

Adjusting the Level of Detail

.

TVG

: Adjusts the appearance of returns to compensate for 

weakened sonar signals in deeper water, and reduces the 

Sonar
