Transducer Type.

Introduction 1

DownVü Sonar View

NOTE: Not all models support DownVü sonar technology and

transducers.

Sonar

NOTE: To receive DownVü scanning sonar, you need a

compatible chartplotter or fishfinder and a compatible
transducer.

DownVü high-frequency sonar provides a clearer picture below
the boat, providing a more detailed representation of structures
the boat is passing over.

Traditional transducers emit a conical beam. The DownVü
scanning sonar technology emits a narrow beam, similar to the
shape of the beam in a copying machine. This beam provides a
clearer, picture-like image of what is beneath the boat.

Sonar Frequencies

NOTE: The frequencies available depend on the 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 cover a larger
area and 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. They can be used to search for structures such as
brush piles.

Selecting a Frequency

Select MENU.

1

Select Frequency or FREQ.

2

Select a frequency.

3

Adjusting the Range of the Depth Scale

You can adjust the range of the depth scale that appears on the
right side of the screen. Automatic ranging keeps the bottom
within the lower third of the sonar screen, and can be useful for
tracking the bottom where there are slow or moderate terrain
changes.

When the depth changes dramatically, like a drop off or cliff,
manually adjusting the range allows a view of a specified depth
range. The bottom is shown on the screen as long as the
bottom is anywhere within the manual range established.

Select MENU > Range.

1

Select an option.

2

• To allow the device to adjust the range automatically
based on the depth, select Auto.

• To increase or decrease the range manually, select

Manual, and select or .

NOTE: Setting the range on one page applies that setting to

all pages.

Adjusting the Zoom

You can adjust the zoom manually by specifying the span and a
fixed starting depth. For example, when the depth is 15 meters
and a starting depth of 5 meters, the device displays a
magnified area from 5 meters deep to 20 meters deep.

You also can allow the device to adjust the zoom automatically
by specifying a span. The device calculates the zoom area from
the bottom of the water. For example, if you select a span of 10
meters, the device displays an magnified area from the bottom
of the water to 10 meters above the bottom.

Select MENU > Zoom.

1

Select Manual or Auto.

2

Select Span and select or to increase or decrease the

3

magnification of the magnified area.
If necessary, select Depth to adjust the zoomed window up

4

or down.
NOTE: The zoomed window tracks the bottom in auto mode

only.

Pausing the Sonar Screen

Select MENU > Pause.

Setting the Sonar Scroll Speed

You can set the rate at which the sonar scrolls from right to left.
A higher scroll speed shows more detail, especially while
moving or trolling. A lower scroll speed displays sonar
information on the screen longer.

Select MENU > Setup > Sonar > Scroll.

1

Select a scroll speed.

2

NOTE: Setting the scroll speed on one page applies that

setting to all the pages.

Configuring the Appearance of Suspended Targets

NOTE: Configuring the appearance of suspended targets on

one page applies that setting to all pages.
NOTE: This feature is not available on all transducers.

Shows suspended targets as symbols.

Shows suspended targets as symbols with target depth
information.

Shows suspended targets as symbols with background sonar
information.

Shows suspended targets as symbols with background sonar
information and target depth information.

Select MENU > Setup > Sonar > Fish ID.

1

Select an option.

2

Sonar Gain and Noise Settings

You can adjust the amount of gain and noise on a sonar screen.
The gain setting controls the sensitivity of the sonar receiver to

compensate for water depth and water clarity. Increasing the
gain shows more detail, and decreasing the gain reduces
screen clutter.

NOTE: Setting the gain on one page applies the setting to all
the pages.

Setting the Gain Manually

Select MENU > Gain > Manual.

1

Select until you begin to see noise in the water portion of

2

the screen.
Select to decrease the gain slightly.

3

Setting the Gain Automatically

Select MENU > Gain.

1

Select an option:

2

• To display higher-sensitivity, weaker sonar returns with
more noise automatically, select Auto-High.

• To display medium-sensitivity sonar returns with
moderate noise automatically, select Auto-Med.

• To display lower-sensitivity sonar returns with less noise
automatically, select Auto-Low.

Alarms

Select MENU > Setup > Alarms.

2 Sonar

Battery: Sounds when the battery reaches a specified low

voltage.

Deep Water: Sounds when the water depth is deeper than the

specified depth.

Drift: Sounds when depth variations at your present location

exceed the specified depth.

Fish: Sounds 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.

Shallow Water: Sounds when the water depth is shallower than

the specified depth.

Water Temperature: Sounds when the water temperature

varies more than ± 2 °F (± 1.1 °C). Alarm settings are saved
when the device is turned off.

NOTE: You must connect the device to a temperature­capable transducer to use this alarm.

System Settings

Select MENU > Setup > System.
Language: Sets the on-screen language.
System Information: Allows you to view software information.

System Unit Settings

Select MENU > Setup > Units.
Depth: Sets the depth units to feet (ft), meters (m), or fathoms

(ftm).

Temperature: Sets the temperature units to Fahrenheit (°F) or

Celsius (°C).
NOTE: You must have a temperature-reading transducer

connected to display the temperature.
