Adjusting the RealVü

Sweep Speed

You can update how quickly the transducer sweeps back and

forth. A faster sweep rate creates a less detailed image, but the

screen refreshes faster. A slower sweep rate creates a more

detailed image, but the screen refreshes more slowly.

NOTE: This feature is not available for the RealVü 3D Historical

sonar view.

From a

RealVü sonar view, select

MENU >

Sweep Speed

Select an option.

Calibrating the Compass

Before you can calibrate the compass, the transducer must be

installed on the shaft far enough away from the trolling motor to

avoid magnetic interference, and deployed in the water.

Calibration must be of sufficient quality to enable the internal

compass.

NOTE:

To use the compass, you must mount the transducer on

the shaft. The compass does not work when you mount the

transducer on the motor.

NOTE:

Compass calibration is available only for transducers

with an internal compass.

You can begin turning your boat before calibrating, but you must

fully rotate your boat 1.5 times during calibration.

From a

ForwardVü or LiveVü Forward sonar page, select

> Sonar Setup > Installation

If necessary, select

Use AHRS.

Select

Calibrate Compass.

Follow the on-screen instructions.

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.

From a sonar view, select MENU

> Sonar Setup >

Appearance > A-Scope > On

Sonar Setup

NOTE:

extend the length of time the information is displayed on

screen. In deeper water, you can select a faster scroll speed.

Automatic scroll speed adjusts the scrolling speed to the

speed the boat is traveling.

Sonar Noise Rejection Settings

From a sonar view, select MENU >

Sonar Setup > Noise

Reject

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.

Color Limit: Hides part of the color palette to help eliminate

fields of weak clutter.

By setting the color limit to the color of the undesired returns,

you can eliminate the display of undesired returns on the

screen.

Smoothing: Removes noise that is not part of a normal sonar

return, and adjusts the appearance of returns, such as the

bottom.
