Garmin ECHOMAP 60 Series Kullanıcı El Kitabı

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.

Shift: Allows you to set the depth range on which the sonar is

focused. This enables you to zoom in to an area within the

focused depth.

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 chartplotter,

sounder modules, and 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 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.

CHIRP generally performs better than single frequency

applications. Because some fish targets may show up better

using a fixed frequency, you should consider your goals and

water conditions when using CHIRP frequencies.

Some sonar black boxes and transducers also provide the ability

to customize preset frequencies for each transducer element,

which enables you to change the frequency quickly using the

presets as the water and your goals change.

Viewing two frequencies concurrently using the split-frequency

view allows you to see deeper with the lower frequency return

and, at the same time, see more detail from the higher

frequency return.

Selecting Frequencies

NOTE: You cannot adjust the frequency for all sonar views and

transducers.

You can indicate which frequencies appear on the sonar screen.

From a sonar view, select MENU > Frequency.

Select a frequency suited to your needs and water depth.

For more information on frequencies, see

Frequencies, page

23.

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.

Sonar Fishfinder

From a sonar view, select MENU > Frequency.

Select Add.

Enter a frequency.

Turning On the A-Scope

NOTE: This feature is available in the Traditional sonar views.

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

showing you what is underneath the transducer right now. You

can use the a-scope to identify target returns that may be

missed when the sonar data is quickly scrolling across the

screen, such as when your boat is moving at high speeds. It can

also be helpful for detecting fish that are close to the bottom.

The a-scope above shows fish returns

return

From a sonar view, select MENU > Sonar Setup >

Appearance > A-Scope.

Select a hold time.

You can increase the hold time to increase the length of time

the sonar returns are displayed.

Panoptix Sonar Setup

Adjusting the RealVü Viewing Angle and Zoom Level

You can change the viewing angle of the RealVü sonar views.

You can also zoom in and out of the view.

From a RealVü sonar view, select an option:

• To adjust the viewing angle, use the arrow keys.

• To zoom in and out, turn the knob.

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.

LiveVü Forward and FrontVü Sonar Menu

From the LiveVü Forward or FrontVü sonar view, select MENU.

Gain: Controls the level of detail and noise shown on the sonar

screen.

If you want to see the highest intensity signal returns on the

screen, you can lower the gain to remove lower intensity

returns and noise. If you want to see all return information,

you can increase the gain to see more information on the

screen. This also increases noise, and can make it more

difficult to recognize actual returns.

Depth Range: Adjusts the range of the depth scale.

Sonar

Allowing the device to adjust the range automatically keeps

the bottom within the lower portion 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
