The X-55 is a high quality, wide screen sonar with performance that is
secondto none in its class. Using menufeaturesand "soft-key"operation,
the X-55 is also one of the easiest-to-use sonars that Lowrancehasever
built.Thewide"Clearvision"screen showstheunderwaterworldwithhigh
resolution and detail. Thedisplayand keyboard are also lighted for night
operation. The X-55 also has digital depth, boat speed, surface water
temperature,and distancetravelled (log) displays. In order to use the
digital speed, temperature,and log displays, you must purchase and

POWER CONNECTIONS
The X-55 works from a twelve-volt battery system. For the bestresults,
attach the powercable directlyto the battery. You can attachthe
power
cable to an accessoryor power buss, howeveryou may have problems
with electrical interference. Therefore, itssaferto goaheadand attach the
powercable directlyto the battery. If thecable is not long enough, splice
#18 gaugewireontoit.Thepowercablehastwowires, red and black. Red
is the positivelead, blackis negative or ground. Make certain to attach the
in-linefuseholdertothe red leadas closetothepowersourceas possible.
Forexample,ifyouhavetoextendthe powercabletothebattery orpower
buss, attach one end of the fuse holder directlyto the batteryor power
buss.This will protectboth the unitand the powercable in the eventof a
short. The X-55 uses a 3-amp fuse.
NOISE
A major causeofsonarproblems is electrical noise. This usuallyappears
onthe sonar'sdisplayas random patterns ofdotsorlines.In severe cases,
it can completely cover the screen with black dots, or cause the unit
operate erraticly, or not at all.
Do notusethisproductwithouta 3-ampfuse wired intothe powercable!
Failure to usea 3-amp fusewill void your warranty.
To eliminate or minimize the effects of electrical noise, first try to
determine the cause. Withthe boat at rest in the water, the firstthingyou
shoulddo isturn all electrical equipment onthe boatoff. Make certain the
engineisoff, also.Turnyour X-55on, then turnoffASP (Advanced Signal
Processing). Thereshould be a steady bottom signal on the display. Now
turn on eachpiece of electrical equipment on the boat andviewtheeffect
on the sonar'sdisplay. For example, turnon the bilge pump and viewthe
sonardisplayfor noise. If no noiseis present, turnthepump off, thenturn
on the VHF radio and transmit. Keep doing this until all electrical
equipmenthas been turned on, their effect on the sonar display noted,
then turned off.

Increasethe RPM with the gearshift in neutral. If noise appears on the
display, the problem could be one ofthreethings; sparkplugs, alternator,
or tachometer wiring. Try using resistor spark plugs, alternatorfilters, or
routing the sonar unit's power cable away from engine wiring. Again,
routing the power cable directly to the battery helps eliminate noise
problems. Make certain to usethe in-line fusesupplied with the unitwhen
wiring the powercable to the battery.

3. Thewater may be deeperthanthe sonar's abilitytofind the bottom. If
the sonar can'tfindthebottom signal while it's in the automatic mode, the
digital willflash continuously. It may change therangeto limitsfar greater
than the water you are in. If this happens, place the unit in the manual
mode,then changetherange to a realistic one, (for example, 0-100feet)
and increase the sensitivity. As you move intoshallowerwater,a bottom
signal shouldappear.

See the transducerowner's manual included with the unitfor complete
transducerinstallation instructions.
SIDESCAN
TheX-55 hasoptionalside-scancapability. To usethis feature,youmust
purchase the ScanPac accessory. To install it, follow the instructions
enclosedwith the ScanPac.
4. Check the batteryvoltage. If thevoltage drops, the unit's transmitter
poweralso drops, reducing its abilityto find thebottom or targets.
See the"Side ScanOperation" section in thismanual for information on
Bottom echodisappears at highspeeds or erratic digital reading or
weak bottomecho while boat is moving
1. The transducer may be in turbulent water. It must be mounted in a
smooth flow of waterin orderfor the sonarto workat all boatspeeds. Air
bubbles inthe waterdisrupt the sonarsignals, interfering with itsabilityto
findthebottom or othertargets. The technical term for this is Cavitation.
To usethespeed, temperature, and distance log features, youmustinstall
an optional speed/temperature sensor. Lowrance manufactures a thruhull sensor/transducercombination unit and a transom mount speed/
temp only sensor.
2. Electrical noisefromthe boat's motorcan interfere with thesonar. This
causes the sonar to automatically increase its Discrimination or noise
rejectionfeature. Thiscancausetheunittoeliminateweakersignalssuch
as fish or even structure fromthe display. Try using resistorspark plugs
or routingthe sonar unit'spower and transducer cables awayfrom other
electrical wiring on the boat.

"AUTO" in the upper left corner of the display indicates
the automatic feature is on.
The digital bottom depth is
also displayedin this box.
2. Make certain the powercableiswired properly. The red wire connects
to the positive batteryterminal, blackto negative or ground.
3. Checkthefuse.
4. Measure the batteryvoltage atthe unit'spowerconnector.It should be
at least 11 volts. If it isn't, the wiring to the unit is defective, the battery
terminals or wiring on theterminals are corroded,or the battery needs
charging.
Unit freezes, locks up, or operates erratically:
1. Electrical noisefromtheboat's motor, trolling motor, or an accessory
may be interfering with thesonar unit. Re-routing thepower and transducer cables away from other electrical wiring on the boat may help.
Route the sonar unit's power cable directly to the battery instead of
througha fuse blockor ignition switch
2. Inspectthetransducercablefor breaks, cuts, or pinched wires.
3. Checkboth the transducer and powerconnectors.Make certain both
are securelyplugged in to the unit.
Weak bottomecho, digital readings erratic,or no fish signals:
1. Makecertaintransducer is pointing straight down.Clean thefaceofthe

With the X-55,anyonecaneliminate guessworkand concentrate on the
areas where fish are likely to be. Even if it's the first time on the lake!
The most efficientway to become acquainted with a bodyof water is to
survey it with your X-55. Start with a map of the lake, if possible, and
indicatethe promising spots in relation to landmarks on shore.
As yougo about your survey, yourX-55will tell youthe depth and typeof

BAIT FISH
The importance of baitfish to successful fishing can't be over-emphasized. They are the principle food of all game fish in mostwaters.
Baitfisharethe plankton feeding foragefish, such as minnows and shad.
Baitfishcanalso betheyoungofgamefish, suchascrappies, bluegill, and
bass.
Most bait fish concentrate within five feet of the surfacewhere sunlight
promotes the growth ofthe plankton on which theyfeed. Onemethodof
fishing isto usethe X-55to findthe baitfishfirst. Withthe Fish ID feature
off, a school of baitfishwill look likea"cloud"on thedisplay.Usually, game
fish will be nearby, often directly beneath theschool of baitfish.
MENUS
The X-55 uses menus extensively to guide you through
the functions and featuresof
the unit. The menu key accesses many of these features, allowing youto customize the unit to your particular
needs and water conditions.

SURVEYING A LAKE
The most successful anglers on anybody of water are thosewho fish it
dayafterdayandyear afteryear. Eventually, they learn thehotspotsthat
producefish consistently. Theydiscoverthroughexperiencewhere, and
at what depth, they can expect to find the fish they want at any season.
And theyrealizethattheseproductive areas changethroughout theyear
depending on waterlevel, temperature, food, and otherfactors.

of the water. For example, from45 to 60 feet. The smallerthesegment,
thebetterthe screen resolution will be. The easiestwayto dothison the
X-55is with the Zoomfeature.This featureexpands the echoes,making
it easierto see detail. For the bestresults, turn the sensitivityup as high
as possible withoutgetting too much noise on the screen. In mediumto
deep water,this method should work to displayfish arches.
If yousee fish signalswhen the unit is in the manual mode, but don't get
fish symbols whenthe Fish l.D.feature is on,tryincreasing thesensitivity.
WATERTEMPERATUREAND THERMOCLINES
Watertemperature hasan important-it not controlling-influence upon the
activitiesofall fish. Fish are cold blooded and their bodiesare alwaysthe
temperature of the surrounding water. During the winter, colderwater
slows down their metabolism. At this time, they need about a fourth as
much food as they consume in the summer.
Mostfishdon'tspawn unlessthewatertemperature iswithin rather narrow
limits. A surface temperature meter helps identifythe desired surface
waterspawningtemperatures forvariousspecies. Troutcan'tsurvivein
streams that get too warm. Bass and otherfish eventuallydie out when
stocked in lakes that remaintoo cold duringthesummer. Whilesomefish
have awidertemperaturetolerance thanothers,each hasacertain range
within whichit triesto stay. Schooling fish suspended over deep waterlie
at the level that provides thistemperature. We assume theyarethe most
comfortable here.
The temperature of water in the lake is seldom constant from top to
bottom. Layers of different temperatures form,andthejunctionofawarm
and cool layerof water is called a thermocline. The depth and thickness
ofthethermoclinecan varywiththeseason ortime of day. In deep lakes
theremaybetwo or moreat different depths. Thermoclines are important
to fishermenbecause they are areas wherefish are active. Manytimes
baitfish will be abovethethermocline while largergame fish will suspend
in or just below it.
The X-55can detect thisinvisible layerinthewater, butthe sensitivitywill
probablyhave to be turned up to see it.

Typically, wide coneangle transducers (20 degrees) are idealfor operatingin shallowto mediumwaterdepths. The20 degreeconeangleallows
youto seemore of the underwaterworld. In 1 Sfeetofwaterthe20degree
cone covers an area about six feet across. The 8 degree transducer
covers only about a two foot circle.
The20degreetransducer is almostalways the bestto usein fresh water,
the8 degree mostly in salt water. In a deep waterenvironment, (300feet
- fresh water, 100 feet - salt water) the narrow cone angle is more
desirable. Sincethe-oundenergyisconcentrated inasmallerarea,itcan
penetrate to much deeperdepths.
Both 8degree and20 degree transducers give accurate bottom readings,
eventhoughthebottomsignal is muchwideronthe2odegreemodel. This
is because you are seeing moreof the bottom. Remember, the shallow
edge ofthesignal showsyouthetruedepth. Therestofthe signal tellsyou
whetheryou are over rocks, mud, etc.
iftheconepassesover a fishin shallowwater, thesignal displayedon the
X-55 maynot arch at all. This is due to the narrowconediameter and the
resolution limitations of the display.
FISH ARCHES
Fish arches are createdwhenthecone of sound passes over a fish. The
distance to afish whentheconefirst strikes it is shown as "A" onthe next
page. Whenthecenterofthe cone strikes the fish, the distance is shorter
as shown "B". As the cone leaves thefish, thedistanceincreases again
as shown in "C".
Very small fish probablywill not arch at all. Medium sized fish will showa
partial arch, or a shapesimilarto an arch if they're in deep water. Large
fish will arch, but turn the sensitivity up in deeper waterto seethearch.
Because ofwaterconditions, suchas heavy surface clutter, thermoclines,
etc., the sensitivity sometimes cannot be increased enough to get fish
arches.

then pressthe right arrow key.
SENSITIVITY
The sensitivity key on theX-55 controls the ability of the unitto pick up
echoes. A low sensitivity level excludes much ofthe bottom information,
fish signals, and othertarget information. High sensitivity levels enables
youtoseethisdetail,but itcanalso clutterthescreen with many undesired
signals. Typically, the best sensitivity level shows a good solid bottom
signal with Graylineand somesurfaceclutter.
Whenthe X-55 is in the Automaticmode,thesensitivity is automatically
adjustedto keep a solid bottom signal displayed, plus a little more. This
gives it thecapabilityto showfish and other detail.
However,situations occur where it becomes necessary to increase or
decreasethe sensitivity. This typically happens when you wish to see
more detail, so an increase in sensitivity is indicated. The procedureto
adjust it isthesamewhethertheunitis in the automatic or manual mode.
Toadjustthe sensitivity, presstheSENSkey. Thesensitivity adjustmenu

Tochange the ASP level, press the MENU key five times. Then press the
key nextto the "ADJUST LEVELOF CHARTASP" labeluntil the desired
level is obtained.
SIGNAL INTERPRETATION
Your X-55 gives an accurate picture of the bottom that your boat is
passing. A bottom of firm sand, gravel, shell, or hard clay returns a fairly
widesignal. Ifthe automatic mode isoff and thesignal narrows down,then
it means thatyouhave moved overa mud bottom. Mud absorbsthesound
wave and returns a weaksignal. Turn up the sensitivity to see a better
bottom signal.
Big rocks or stumps on a smooth bottom send back signals above the
bottom level signal. The height of the signal depends on the target's
height. Asyou passover apost, it shouldbe clearly visibleas ashort line
extending abovethe bottomsignal.
A steep
slope returns a wide signal, the steeper the wider. Signals
returned from a high underwater cliff are usuallythe widestof all.
The sensitivity menu has left
and right arrows, plus a horizontal bar graph. The graph
givesa visual indication of the
sensitivity level. The number
above the INC arrow also
showsthe percentage of sensitivityin use.
When the Fish ID. mode is off, the depth of the water will affectthe size
and shapeofthe fish arch due to the coneanglediameter. For example,
ifthe conepassesoverafish inshallowwater,the signal displayed on the
X-55 maynot arch at all. Thisis due tothenarrowconediameter and the
resolution limitations of the display.
To increasethesensitivity level,
press the right arrow key. As
you press the key, the menu's
bar graph will grow wider and
thepercentage will increase in value.You canalso seethedifference on
thechart record as it scrolls. When the sensitivity is atthe desired level,
release the key.
To decreasethe sensitivity level, press the key adjacent to the leftarrow.
The bargraph and percentage will decrease. Whenthe sensitivity is atthe
desired level, release the key.
Whenyou reach either the maximum or minimum limit, a tone sounds.

TheSurfaceClarityControl (5CC) reduces or eliminates surface clutter
signals from the display. 3CC varies the sensitivity of the receiver,
decreasing it nearthe surface and gradually increasing it as the depth
increases. Themaximum depth that5CCwill affect is75%oftheselected
depth range. For example, on a 0-60 foot range with maximum 8CC,
surface clutter will be reduced down to 45 feet.
There are three levels of 8CC available on the X-55: low, medium, and
high. When it'sturnedon forthe firsttime,the8CC level is low. To change
it, press the MENU key five times, then press the key adjacent to the
"ADJUST CHARTSURFACE CLARITY" label until the black boxisonthe

Press the key nextto the "EXIT" label when you're finished.
ASP (Advanced Signal Processing)
The ASP feature is a noise rejection system built into the X-55 that
constantly evaluates the effects of boat speed, water conditions, and
interference. Thisautomatic feature gives youthe bestdisplaypossible
undermostconditions.
TheASP feature is an effectivetool in combating noise. In sonarterms,
noise is anyundesired signal. It is causedby electrical and mechanical
sources such as bilge pumps, engine ignitionsystems and wiring, air
bubbles passing overthe faceof the transducer, even vibrationfrom the
engine. In all cases, noisecan produceunwanted marks on the display.
TheASPfeature hastwo levels - Normal and High. Ifyouhavehighnoise
levels,try using the"Nigh"ASPsetting. However, ifyouare having trouble
with noise, we suggestthat youtake steps to findtheinterference source
and fix it, ratherthan continually usingthe unitwith the highASPsetting.

GRAYLINE®
GRAYLINE lets you distinguish between strong and weak echoes. It
"paints" gray on targetsthat are stronger than apresetvalue.This allows
youto tellthe difference between a hard and soft bottom.Forexample, a
soft,muddy or weedybottom returns aweakersignal whichis shown with
a narrowor no gray line. A hard bottom returns a strong signal which
causesa wide gray line.
Ifyou have two signals of equal size, one with gray andtheotherwithout,
then the target with gray is the stronger signal. This helps distinguish
weedsfrom trees on the bottom, or fish from structure.
