Enter the depth at which the alarm is triggered, and select 

Done

.

On the FrontVü screen, a depth line shows the depth at which 

the alarm is set. The line is green when you are in a safe depth. 

The line turns yellow when you are going faster than the forward 

range gives you time to react (10 seconds). It turns red and 

sounds an alarm when the system detects an obstruction or the 

depth is less than the entered value.

 CAUTION

The ability to effectively avoid running aground with FrontVü 

sonar decreases as your speed rises above 8 knots.

LiveVü and FrontVü Appearance Settings

From a LiveVü or FrontVü Panoptix sonar view, select 

MENU

 > 

Sonar Setup

 > 

Appearance

.

Color Scheme

: Sets the color palette.

Color Gain

: Adjusts the intensity of colors shown on the screen.

You can select a higher color gain value to see targets higher 

in the water column. A higher color gain value also allow you 

to differentiate low intensity returns higher in the water 

column, but this causes a loss in the differentiation of the 

returns at the bottom. You can select a lower color gain value 

when targets are near the bottom, to help you distinguish 

between targets and high intensity returns such as sand, 

rock, and mud.

Trails

: Sets the how long the trails appear on the screen. The 

trails show the movement of the target.

Bottom Fill

: Colors the bottom brown to distinguish it from the 

water returns.

Grid Overlay

: Shows a grid of range lines.

Scroll History

: Shows the sonar history in a traditional sonar 

view.

RealVü Appearance Settings

From a RealVü sonar view, select 

MENU

 > 

Sonar Setup

 > 

Appearance

.

Point Colors

: Sets a different color palette for the sonar return 

points.

Bottom Colors

: Sets the color scheme for the bottom.

Bottom Style

: Sets the style for the bottom. When you are in 

deep water, you can select the Points option and manually 

set the range to a shallower value.

Color Key

: Shows a legend of the depths the colors represent.

Panoptix Transducer Installation Settings

From a Panoptix sonar view, select 

MENU

 > 

Sonar Setup

 > 

Installation

.

Install Depth

: Sets the depth below the water line where the 

Panoptix transducer is mounted. Entering the actual depth at 

which the transducer is mounted results in a more accurate 

visual presentation of what is in the water.

Bow Offset

: Sets the distance between the bow and the forward 

view Panoptix transducer installation location. This allows 

you to view the forward distance from the bow instead of the 

transducer location.
This applies to Panoptix transducers in the FrontVü, LiveVü 

Forward, and RealVü 3D Forward sonar views.

Beam Width

: Sets the width of the down view Panoptix 

transducer beam. Narrow beam widths allow you to see 

deeper and farther. Wider beam widths allow you to see 

more coverage area.
This applies to Panoptix transducers in the FrontVü, LiveVü 

Down, and LiveVü Forward sonar views.

Use AHRS

: Enables the internal attitude heading and reference 

system (AHRS) sensors to detect the installation angle of the 

Panoptix transducer automatically. When this setting is 

turned off, you can enter the specific installation angle for the 

transducer using the Pitch Angle setting. Many forward view 

transducers are installed at a 45-degree angle and down 

view transducers are installed at a zero-degree angle.

Flipped

: Sets the orientation of the Panoptix sonar view when 

the down view transducer is installed with the cables pointing 

toward the port side of the boat.
This applies to Panoptix transducers in the LiveVü Down, 

RealVü 3D Down, and RealVü 3D Historical sonar views.

Calibrate Compass

: Calibrates the internal compass in the 

Panoptix transducer (

Calibrating the Compass

, page 29

).

This applies to Panoptix transducers with an internal 

compass, such as the PS21-TR transducer.

Orientation

: Controls if the transducer is in down or forward 

installation mode. The Auto setting uses the AHRS sensor to 

determine the orientation.
This applies to PS22 and LiveScope transducers.

Focus

: Adjusts the sonar view to compensate for the speed of 

sound in water. The Auto setting uses the temperature of the 

water to calculate the speed of sound.
This applies to LiveScope transducers.

Restore Sonar Defaults

: Restores the sonar settings to the 

factory default values.

Setting the Bow Offset

For forward view Panoptix transducers, you can enter a bow 

offset to compensate the forward distance readings for the 

transducer installation location. This allows you to view the 

forward distance from the bow instead of the transducer 

installation location.
This feature applies to Panoptix transducers in the FrontVü, 

LiveVü Forward, and RealVü 3D Forward sonar views.

Measure the horizontal distance 

À

 from the transducer to the 

bow.

Enter the distance measured, and select 

Done

.

On the applicable sonar view, the forward range shifts by the 

distance you entered.

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.
