INTRODUCTION
Welcome totheworldofsportfishing sonar. YourEagle Fishl.D. and
Fish 1.0. Plus arehighqualitysonar designed forboth professional and
novice users.These units have an automatic featurethat finds and
displays
thebottom
depth,
fish, and structure. Asyou becomefamiliar
with your Fish 1.0., you can "fine tune" the unit to thesurrounding
conditionstogetthemostfromyoursonar.
(Note: Alloperating

the sameexcept forspeedand temperature. OnlytheFish l.D. Plus
hasthosefunctions. Tosimplify thismanual, allreferences totheFish

To get startedwith your Fish l.D., first readthe installation section.
Thisiswhereitallbegins, and improper installation cancause

INSTALLATION
Mounting
Install theunitin any convenient location, provided
thereisclearance
whentiltedforthebest

woodscrew or
through
boltmounting. Place apiece ofplywood onthe
backofthinpanelsto secure themounting hardware. Makecertain
there is enough room behind the unit to attach the power and
transducercables.
You can routethepowerand transducer cables through
the one inch
holeinthebaseofthe
gimbal
bracket. Thenpassthem
through
ahole
inthe
mounting surface. Firstpass
thetransducerconnectorandcable

through
thebracketanddash. After routing thecables,fill
the holewith siliconerubber adhesive (RTV). Offsetthe bracketto
coverthemajoilty

PowerConnections
TheFishl.D.operates froma12voltbatterysystem. Attachthe
power
cable to an accessoryor power buss. If you have problemswith
electrical interference, then attach the cable directlyto the battery.

WATERTEMPERATUREANDTHERMOCLINES
Water
temperature has an important-if notcontrolling-influence upon
theactivitiesof all fish. Fish are cold blooded and their bodies are
always thetemperature

colder waterslows downtheir metabolism. Atthistime, they need

TheFishI.D. featureis

Thecomputer insidetheunit
analyzes allechoes,

unwanted

desirable signals. The remaining suspended targetsare usuallyfish.

medium,or large fishsymbols on the display. These symbols are

NOTE:TheFish 1.0.fea-
ture cannot distinguish
between fish and other
suspendedobjects such
asturtles,treebranches,
trotlines, submerged
floats,
orotherinanimate
objects.Themicro-com-
puter in this unit is so-
phisticated, but itcanbe
fooled. Themostdifficult
challenge is individual
tree branchesextending
out from groups of
branches.Thesecanbe
mis-identified as fish by
the Fish l.D. feature.
Also, large amounts of
noise can fool the Fish
I.D. feature. Thisisusu-
ally caused by a poor
transducer
installation.
Although the Fish 1.0.
feature isn't perfect, it
can beavaluableaidto
