LORAN TROUBLESHOOTING

1. You

must have an 8' antenna.

Preferably,

the entire

length

of the

antenna

should be

higher

than

anything

else on the boat.

2. For best

results,

wire the

power

cable

directly

to the

battery,

preferably

the main

engine's cranking

battery.

This assures

the

boat

will be

grounded,

since the lower unit

is in the water.

If

you're

using

an isolated

battery,

wire a

grounding plate

to the

ground

side

of the

battery.

The loran will work better if it's

grounded

to water.

The

temperature

pf water in the

lake is seldom constant

from

top

to

bottom.

Layers

of different

temperatures

form,

and the

junction

of a

warm and cool

layer

of water is called

a thermocline. The

depth

and

thickness of the thermocline

can

vary

with

the season or time

of

day.

In

deep

lakes

there

may

be two or more at

different

depths.

Thermoclines

are

important

to

fishermen because

they

are areas where fish

are

active.

Many

times bait

fish wilt be above

the thermocline while

larger

game

fish

will

suspend

in or

just

belowit.

The UttraNav can detect

this invisible

layer

in the

water,

but the

sensitiv-

ity

will

probably

have to be turned

up

to

see it.
