Selecting the Transducer Type

Before you can select the transducer type, you must know what

kind of transducer you have.

This chartplotter is compatible with the Garmin ClearVü

transducer as well as a range of accessory transducers

including Garmin

GT transducers, which are available at

www.garmin.com.

If you are connecting a transducer that was not included with the

chartplotter, you may need to set the transducer type to make

the sonar function properly. If the device automatically detected

your transducer, this option does not appear.

From a sonar view, select Menu

> Sonar Setup >

Installation > Transducer Type

Select an option:

• If you have a 200/77 kHz, dual-beam transducer, select

Dual Beam (200/77 kHz).

• If you have a 200/50 kHz, dual-frequency transducer,

select

Dual Frequency (200/50 kHz).

• If you have another type of transducer, select it from the

list.

Sonar Setup

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

modules, and transducers.

Sonar Settings

NOTE:

These settings do not apply to Panoptix transducers.

See

RealVü Sonar Settings, page 23 and LiveVü

Sonar

Settings, page

23.

From a sonar view, select Menu > Sonar Setup.

Scroll Speed: Sets the rate at which the sonar scrolls from right

to left (Setting the Scroll Speed,

page

21).

In shallow water, you can select a slower scroll speed to

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.

Noise Reject: Reduces the interference and the amount of

clutter shown on the sonar screen (Sonar Noise Rejection

Settings

, page

23).

Appearance: Configures the appearance of the sonar screen

(Sonar Appearance Settings, page 23).

Alarms: Sets sonar alarms (Sonar Alarm Settings

, page

24).

Advanced: Configures various sonar display and data source

settings (Advanced Sonar Settings,

page

24).

Installation: Configures the transducer (Transducer Installation

Settings, page 24).

RealVü Sonar Settings

From a

RealVü sonar view, select

Menu > Sonar Setup.

Point Colors: Sets a different color palette for the sonar return

points.

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

deep water, you can set this setting to the Points

and

manually set the range shallower.

Bottom Colors: Sets the color scheme for the bottom.

Color Key: Shows a legend of the depths the colors represent.

Overlay Data: Sets the data shown on the sonar screen.

Installation: Configures the transducer (Transducer Installation

Settings, page 24).

LiveVü Sonar Settings

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

Color Scheme: Sets the color palette.

Bottom Fill: Colors the bottom brown to distinguish it from the

water returns.

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

trails show the movement of the target.

Grid Overlay: Shows a grid of range lines.

Noise Reject: Reduces the interference and the amount of

clutter shown on the sonar screen.

Scroll History: Shows the sonar history in a traditional sonar

view.

Overlay Data: Sets the data shown on the sonar screen

(Customizing the Data Overlays, page 3).

Installation: Configures the transducer (Calibrating the

Compass,

page

20)

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.

When smoothing is set to high, more of the low-level noise

remains than when using the interference control, but the

noise is more subdued because of averaging. Smoothing can

remove speckle from the bottom. Smoothing and interference

work well together to eliminate low-level noise. You can

adjust the interference and smoothing settings incrementally

to remove undesirable noise from the display.

Surface Noise: Hides surface noise to help reduce clutter.

Wider beam widths (lower frequencies) can show more

targets, but can generate more surface noise.

TVG: Adjusts the time varying gain, which can reduce noise.

This control is best used for situations when you want to

control and suppress clutter or noise near the water surface.

It also allows for the display of targets near the surface that

are otherwise hidden or masked by surface noise.

Sonar Appearance Settings

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

Color: Sets the color scheme and color gain.

Overlay Data: Sets the data shown on the sonar screen.

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

screen that shows instantaneously the range to targets along

a scale.

Depth Line: Shows a quick-reference depth line.

Edge: Highlights the strongest signal from the bottom to help

define the hardness or softness of the signal.

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
