down to a

minimum when

looking

for fish.

However,

it is

helpful

sometimes

to have

longer pulse

width when

resolution is not a concern. When

using

a sonar in

deeper

water,

it is

easier for the unit to detect a

longer pulse coming

back from the

bottom or from fish. This is called

"Probability

of Echo Detection".

The

probability

of the unit

being

able to detect an echo

returning

from

deep

water is diminished

because the further the sound

pulse

has to

travel,

the weaker it

becomes.

By broadening

the

pulse

length,

essence,

larger signal

is transmitted and it is easier for

the receiver to detect it.

For this

reason,

the micro-com-

puter

in the X-1 6

automatically

increases the initial

pulse length

the unit as

deeper

lower limits are

set

the

operator. (Note:

Initial

pulse length

is the

pulse length

the unit when the

Suppressor

control is set to

minimum.)

From 200 feet to 599

feet,

the

initial

pulse length

increases at the

same rate as the

depth.

For

example,

with the LOWER LIMIT

set to 260

feet,

the initial transmit

pulse length

would be 260

p5.

the LOWER LIMIT is set to 390

feet,

the

initial transmit

pulse

would be 390

per

foot OVER 600 feet. In other

words,

with a lower limit of 700

feet,

the initial transmit

pulse

length

would be 1100 micro-

seconds.

The transmit

pulse length

can

be increased from the initial

point

any

time

by using

the

Suppressor

control. The maximum

amount

added to

the initial transmitter

pulse length

words,

if the

LOWER LIMIT is set

to 420

feet,

and the

Suppressor

control is

increased to the

maximum, (press

the transmitter

pulse

length

would be 1220 micro-

seconds.

(420

The amount that the initial

transmit

pulse length

is increased

with

suppression

is listed in the

following

chart.

Remember,

the

number in

the

right

hand column

is the amount added to the initial

transmit

pulse length.

When
