Lowrance electronic X-3 iui

SCALE Remember, there must be some

movement between the boat and the fish

There are ten scale markers

printed on both sides of the X-3's display

help determine what the depth

of a target

is. For

example,

if the

depth

range is 0 to 60 feet, then each mark is equal

to six feet. If

the target

(such as a

fish) was next to

the 5th line,

then it is 30 feet deep (5 lines

times six feet=30

feet). To make it easier to use the

depth scale, use

ranges in multiples

often, i.e. 10, 30, 140, etc.

to develop

the arch. Usually

this means trolling at

very slow

speeds

with

the main engine in gear

at a minimum throttle

setting.

The

depth of the water will affect the size and shape of the fish arch due

to the

cone

angle diameter. For

example, if the cone passes

over a fish in

shallow water,

the

signal displayed

the X-3 may not arch at

all, due to

the narrow cone diameter and the resolution

limitations of

the display.

Compared

to a

paper graph,

the X-3 cannot

show as fine detail because

the pixels (dots

on the

screen)

are much larger

than a

paper graph's.

Therefore,

the X-3 cannot show fish arches as well as a

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

sensitivfty must be turned up, especially in

deeper

water There will be times when the sensitivity

cannot be turned

high enough to

get

fish arches because of the heavy

surface clutter,

therrnoclines,

etc.

One of

the best ways to

get

fish arches is to

expand or "zoom" a seg-

ment of the water, for

example

40 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.

LOWER LIMIT

To change the lower limit, press

the lower limit desired from 10 feet to

999 feet and then press

the LOWER LIMIT key. The

display will imme-

diately change to the new depth range and display

the new lower limit at

the bottom of the screen.

The lower limit may be changed anytime, even if the AUTO RANGE func-

tion is on. However,

if a lower limit is selected that is less than the depth

of the bottom while the unit is in the AUTO

RANGE mode, it won't

the entry For

example, suppose

the X-3 is in the AUTO RANGE, mode

and the lower limit is 75 feet with the bottom at

60 feet If a new lower

limit of 55 feet were entered on the

keyboard, the X-3 would chirp, and

keep the lower limit

setting of 75 feet.
