TRANSDUCER

CONE ANGLES

The sound

waves from the transducer

spread

out into the water in a cone

shaped

beam. This looks much like the

beam from

aflashlight.

The

angle

between

the outside

edges

of the cone is

the cone

angle.

Lowrance

offers a choice of transducers with either

an 8 or2O

degree

cone

angle.

Thetransducersupplied

withthe X-55 has

a2Odegree coneangle.

Typically,

wide cone

angle

transducers

(20 degrees)

are ideal for

operat-

ing

in shallow to medium

water

depths.

The 20

degree

cone

angle

allows

you

to see more of the underwaterworld.

In 1 Sfeet of waterthe 20

degree

cone

covers an area

about six feet across. The 8

degree

transducer

covers

only

about a two foot circle.

The

degree

transducer is

almost

always

the best to use in fresh

water,

the8

degree mostly

in salt water.

In a

deep

water

environment, (300

feet

fresh water,

100 feet

salt

water)

the narrow cone

angle

is more

desirable. Sincethe -ound

energyis

concentrated in

asmallerarea,

itcan

penetrate

to much

deeper depths.

Both

degree

and 20

degree

transducers

give

accurate bottom

readings,

eventhoughthe

bottom

signal

is muchwideronthe

2odegree

model. This

is because

you

are

seeing

more of the

bottom.

Remember,

the shallow

edge

of the

signal

showsyouthetrue depth.

The

restof the

signal tellsyou

whether

you

are over

rocks, mud,

etc.

if the cone

passes

over

a fish in shallow

water,

the

signal displayed

on the

X-55

may

not arch at all. This

is due to the narrow cone diameter

and the

resolution limitations

of the

display.

FISH

ARCHES

Fish arches

are created when

the cone of sound

passes

over a

fish. The

distance

to a fish when the cone first

strikes it is shown as "A" on the

page.

When

the center of the cone strikes

the

fish,

the distance

is shorter

as shown

"B". As the cone leaves the

fish,

the distance increases

again

as shown

in "C".

Very

small

fish

probably

will not arch at

all. Medium sized fish will show

partial

arch,

or a

shape

similar to an arch

they're

deep

water.

Large

fish will

arch,

but

turn the

sensitivity up

deeper

water to see the arch.

Because

waterconditions,

such as

heavy

surface

clutter, thermoclines,

etc.,

the

sensitivity

sometimes cannot be increased

enough

fish

arches.

One of the best

ways

get

fish arches is to
