will

that the ID-6300 is in the manual mode. To increase

and hold the

in the same manner.

SENSITIVITY: TOO LOW SENSITIVITY: PROPER

If a

partial

arch occurs most of the time on

your

unit

(the

mark

curves

up,

but not

back

down,

vice-versa)

it could be the transducer

not

pointing straightdown.

Adjust

atransom mounted transducer

until the

fish show the distinctive arch. This

may

take some

trial and error until

you

achieve the correct

mounting.

Remember,

there must be some movement between the boat

and

thefishtodevelopthe

arch.

The

depth

of the waterwill affectthe size and

shape

of the fish

arch

due to the cone

angle

diameter. For

example,

ftthe cone

passes

over a fish

in shallow

water,

the

signal displayed

on the ID-6300

may

not

arch at all.

This isdue tothe narrow cone diameter and the resolution limitations

ofthe

display.

Even the 20

degree

transducer has

only

a 3 foot diameter

at this

depth.

Compared

to a

paper graph,

a ID-6300 cannot

show as fine of

detail. The reason for this is the

pixels (dots

on the

screen)

are

much

larger

than a

paper graph's markings.

Therefore,

the lD-6300 cannot show

fish

arches as well as a

graph.

Plus,

requires

a bit

more work

initially

to read

and

interpret

the screen than a

paper graph.

Very

small fish

probably

will not arch at all. Medium sized

fish will

show a

partial arch,

or a

shape

similar

Because of water

such as

fish

arches.

One of the best

ways

get

fish arches is to

expand

or "zoom" a

segment

ofthewater. For

example,

40 to 60 feet. The

smallerthe

segment,

the betterthe screen resolution will be.

Then,

turn

the

sensitivity

without

getting

too much noise on the screen. In

medium to

water,

this method should work to

display

fish

arches.

WATER TEMPERATURE AND TI-JERMOCLINES

Water

temperature

has an

important-ft

not

controlling-influence

upon

the activities of all fish. Fish are cold blooded

and their bodies are

alwaysthetemperatureofthesurroundingwater.

During

thewinter,

colder

water slows down their metabolism,

Atthis

time,

they

need

about a fourth

as much food as

they

consume in the summer.
