Allowing the device to adjust the range automatically keeps the

bottom within the lower or outer third of the sonar screen, and

can be useful for tracking a bottom that has minimal or moderate

terrain changes.

Manually adjusting the range enables you to view a specified

range, which can be useful for tracking a bottom that has large

terrain changes, such as a drop-offs or cliffs. The bottom can

appear on the screen as long as it appears within the range you

have set.

From a sonar view, select Menu > Range.

Select an option:

• To allow the chartplotter to adjust the range automatically,

select Auto.

• To increase or decrease the range manually, select Up or

Down.

TIP: From the sonar screen, you can select or to

manually adjust the range.

TIP: When viewing multiple sonar screens, you can select

Select Position to choose the active screen.

Sonar Appearance Settings

From a sonar view, select Menu > Sonar Setup > Appearance.

Color Scheme: Sets the color scheme.

A-Scope: Displays a vertical flasher along the right side of the

screen that shows instantaneously the range to targets along

a scale.

Edge: Highlights the strongest signal from the bottom to help

define the hardness or softness of the signal.

Fish Symbols: Sets how the sonar interprets suspended

targets.

Shows suspended targets as symbols and background sonar

information.

Shows suspended targets as symbols with target depth

information and background sonar information.

Shows suspended targets as symbols.

Shows suspended targets as symbols with target depth

information.

Sonar Alarms

NOTE: Not all options are available on all transducers.

From an applicable sonar view, select Menu > Sonar Setup >

Alarms.

You can also open the sonar alarms by selecting Settings >

Alarms > Sonar.

Shallow Water: Sets an alarm to sound when the depth is less

than the specified value.

Deep Water: Sets an alarm to sound when the depth is greater

than the specified value.

FrontVü Alarm: Sets an alarm to sound when the depth in front

of the vessel is less than the specified value, which can help

you avoid running aground (Setting the FrontVü Depth Alarm,

page 24). This alarm is available only with Panoptix FrontVü

transducers.

Water Temp.: Sets an alarm to sound when the transducer

reports a temperature that is 2°F (1.1°C) above or below the

specified temperature.

Fish

Fish: Sets an alarm to sound when the device detects a

suspended target.

• sets the alarm to sound when fish of all sizes are

detected.

• sets the alarm to sound only when medium or large

fish are detected.

• sets the alarm to sound only when large fish are

detected.

Advanced Sonar Settings

NOTE: Not all options and settings apply to all models and

transducers.

From a sonar view, select Menu > Sonar Setup > Advanced.

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, page 20.

TVG: Adjusts the appearance of returns to compensate for

weakened sonar signals in deeper water, and reduces the

appearance of noise near the surface. When the value of this

setting is increased, the colors associated with low-level

noise and fish targets appear more consistent through

various water depths. This setting also reduces the noise

near the surface of the water.

Transducer Installation Settings

NOTE: Not all options and settings apply to all models and

transducers.

From a sonar view, select Menu > Sonar Setup > Installation.

Restore Sonar Defaults: Restores the factory default settings

for the sonar view.

Transducer Type: Allows you to select the type of transducer

that is connected to the device.

Flip Left/Right: Changes the orientation of the SideVü sonar

view when the transducer is installed backward.

Flipped: Sets the orientation of the Panoptix sonar view when

the transducer is installed with the cables pointing toward the

port side of the boat.

Beam Width: Sets the width of the Panoptix transducer beam.

Narrow beam widths allow you to see deeper and farther.

Wider beam widths allow you to see more coverage area.

Use AHRS: Allows the internal attitude heading and reference

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

Panoptix transducer. When this setting is turned off, it is

assumed the transducer is installed at a 45-degree angle.

Sonar Frequencies

NOTE: The frequencies available depend on the device and

trandsucers 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 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.

CHIRP frequencies allow you to sweep each pulse through a

range of frequencies, resulting in better target separation in

deep water. CHIRP can be used to distinctly identify targets, like

individual fish in a school, and for deep water applications.
