You

NOTE:

Not

features.

DownVu

Sonar

View

NOTE:

Not

all

models

support

DownVu

sonar

technology

and

transducers.

NOTE:

To

receive

DownVu

scanning

sonar,

you

need

a

compatible

chartplotter

or

fishfinder

and

a

compatible

transducer.

DownVu

high-frequency

sonar

provides

a

clearer

picture

below

the

boat,

providing

a

more

detailed

representation

of

structures

the

boat

is

passing

over.

Traditiona.l

transducers

emit

a

conical

beam.

The

DownVu

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

6

frequency

has

better

deep

water

penetration.

They

can

be

used

to

search

for

structures

such

as

brush

piles.

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.

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

screen

as

long

as

the

bottom

is

anywhere

NOTE:

Setting

applies

that

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
