Remember,

there must be

some

movement between the

boat and the

fish to

develop

the

arch.

Usually

this

means

trolling

at

very

slow

speeds

with

the main

engine

in

gear

at a

minimum throttle

sefting.

The

depth

of the water

will alfect the size and

shape

of the fish arch

due to the

cone

angle

diameter. For

example,

if the

cone

passps

over a

fish

in shallow

water,

the

signal

displayed

on the

Z-6100

may

not

arch at

all,

due to the narrow

cone

diameter and the

resolution imitations of

the

display.

Even the 20

degree

transducer has

only

a 3 foot

diameter at this

depth.

Compared

to a

paper

graph,

a

Z-6100 cannot show

as fine of detail

because the

pixels

(dots

on the

screen)

are

much

arger

than a

paper

graph's

markings.

Therefore,

the

Z-6100 cannot

show fish arches

as well

as a

graph,

and it

requires

a

bit more work

initially

to read and

interpret

the screen than a

peper

graph.

Very

small fish

probably

will not

arch at

all,

while

medium sized

fish will

show

a

partial.arch,

or a

shape

similar to an

arch if

they're

in

deep.water,

Large

fish will

arch,

but the

sensitivity

needs to be

turned

up

in

deeper

water to see the

arch. Because of

water

conditions,

such as

heavy

surface

clutter,

thermoclines, etc.,

the

sensitivity

sometimes

cannot be

turned

high

enough

to

get

fish arches.

One of the

best

ways

to

get

fish arches is

to

expand

or "zoom"

a

segment

of

the

water,

for

example

30 to 60 feet

The smaller the

segment,

the better the

screen

resolution will be.

Then,

turn

up

the

sensitivity

as

high

as

possible

without

getting

too much

noise on the

screen. In

medium to

deep water,

this method

should work to

display

fish arches.

Installation instructions for

the

permanent

mount

transducer are

supplied

with the

transducer in a

separate

package.

Please read the

instructions

carefully

before

you

start

installing

the transducer.

NOISE

Electrical noise

picked

up by

the

power

cable can be minimized

by

routing

it

away

from

other

possible

sources

of electrical

interference. One

of

the

largest

noise

generators

is the

engine's wiring

harness that runs

from the

engine

to the

instrument

panel.

This

harness

usually

contains a

wire for the

tachometer

which radiates RF

(radio

frequency) energy.

For

best

results,

keep

the

power

and transducer

cables

away

from the

engine

wiring.

Also,

bilge

pump wiring

can

sometimes radiate noise so

try

to

keep

the Z-6100's

cables

away

from those wires.

VHF radio

antenna cables

radiate RF

ehergy

at

higher

power

levels

than even the

engine's wiring

harness, It is

very important

to

keep

the

Z-6100's

power

and

transducer cables as far

away

as

possible

from a

VHF radio antenna

cable.

If there is no

noise—interference—on the unit when the

boat is

sifting

still with the

engine running

in

neutral,

but

interference

begins

at slow

boat

speeds,

worsening

as the boat

speed

increases,

then a

probable

caUse

is acoustic

noise,

or

cavitation. This noise is not

electrical,

but

rather

mechanically

induced noise from

the transducer.

Usually,

acoustic

noise is created

by

air

bubbles

passing

over the face of

the transducer.

The

faster a boat

travels,

the more air

bubbles increase

and

generate

noise on the

display.

To eliminate

this

problem,

read the transducer

owner's

manual for

proper

mounting techniques.
