• Elevenuserselectablefrequencies
from20to30kHzprevents
interferencefromothervessels.
• Fastmovingobjectslikemackerel
andtunaaredetectedfurtheraway
thanwithCW(continueswave)
usingtheHyperbolicFMmode.
• Inareaswithhardbottom,longer
detectionrangeisaccomplished
bycombininganarrowtransmitter
beamwithaspecialdesigned
narrowreceiverbeam.This
removesmostofthedisturbing
bottomechoesfromthesidelobes,
commonlyseenonothersonar
models.
• Thereceiver’swidedynamic
rangeeasilyidentiesschoolswith
Longerrangewithbetterresolution-samehigh

beamwidthstiedin
withlong,medium
andshortrangesettings
improvecloserangedetection.
• At30kHzoperatingfrequency,the
beamwidthisonly6.7°.
• Anew180°verticalviewtiltable

TheSimradSX90isalowfrequency,high-definition;longrange
sonar,designedforvesselswherelongdetectionrangeisimportant.
Horizontal and vertical beams
Thecombinationofverticalandhorizontal
presentationsshowyoutheschoolsofshboth
fromaboveandfromthesideatthesametime.
Itisnotnecessarytogooverthetargettosee
theverticaldistributionontheechosounder.
Bow up/180° vertical
Theverticalsliceismade“tippable”,andby
selectinga60°tipangle(orless),afull180°
coverageisobtained.Thetipanglecanbe
adjustedfrom+10to-90°.Thismodeisideal
whenyouaretrawlingforshondeepwater.
Beam stabilization
Whenthebeamstabilizerisactivated,
boththehorizontalandverticalbeamsare
electronicallystabilizedforrollandpitch.The
fullcirclebeamstaysonthetargetindependent
ofthevesselmovement,eveninroughseas.
• Thelongrangeandhigher

yourcatchingabilities,andhelps
youtomakebetteruseofyour

360° Omnidirectional sonar
TheSX90transmitsanarrow
verticalbeam360°aroundthevessel.
Thehorizontalresolutionisasnarrow
as8.5°makingsharpedgesaroundthe
schoolduringevaluationofdifferent
targets.
90° Vertical Tip
Thisanewfeatureonoursonars.
Wetransmitanarrowforward-looking
fan-shaped180°widebeam.Thefan
beamcanbetiltedfrom+10°and
downto-90°.Thisfeatureisspecially
designedforpelagictrawlers.
20 to 30 kHz
TheSX90sonarcanoperateon
11differentfrequenciesfrom20to
30kHz.Lowerfrequencygiveless
absorptionandwiderbeamforlong
rangeindeepwater,whererange
islimitedbysalinity.Thehigher
frequenciesprovidenarrowerbeams
foruseinshallowwaterswererange
islimitedbyreverberation.Youwill
alsoavoidinterferencefromother
sonarsinthearea
Narrow sound beams
Unlikeothersonars,theSX90both
transmitsandreceiveswithnarrow
beams.Narrowbeamsareimportant
inordertoavoidfalseunwanted
echoesfrombottomandsurface,this
limitsthedetectionrange.At30kHz
thetransmitbeamisonly6.7°wide.
Thereceiverbeamisonly7.4°.
Selectable beam width
Withanarrowbeamyou
continuouslyneedtooperatethetiltto
keepthebeamontheschool.During
thebusycatchingtime,twowider
verticalbeamscanautomaticallybe
selected.Targettrackingisthenmade
lessdependentonthetiltangle.
TheSimradSX90sonarusestheultimateofmodern
technologytodetecttargetsunderdifcultconditions.
Hyperbolic FM
ThisisanotheruniqueSimrad
feature.TheSX90sonartransmits
alongpulsewithacontinuously
variablefrequency.Thereceiver
listensforanechowiththesame
frequencyvariations.Echoeswith
differentfrequencysignaturesare
vastlyreduced.Theactualshechoes
areenhanced,andshdetectionis
madeeasierunderdifcultconditions.
HyperbolicFMgivesyou30times
betterrangeresolutionthancommon
CWtransmissions.
Large dynamic range
Pickingtherightschoolis
important.Dynamicrangemeansthat
youcantellthedifferencebetweena
scatteredschoolprovidingaweaker
echo,andadenseschoolgivinga
strongerecho.Lookingatthebottom
echo,youcaneasilytellsmoothfrom
roughbottom.Thisisimportantwhen
purseseininginshallowwater,and
duringpelagictrawlingwherethe
footropecantouchthebottom.
Stabilized beams
TheSX90sonarisvertically
stabilizedevenly360°aroundthe
ship,bothforthehorizontalaswell
astheverticalbeams.Thestabilized
sonarbeamsenhanceshdetectionin
poorweathermakingsearchingstill
possibleinsituationsyouearliergave
up.
Dual mode
Conditionsmaysometimeschange
veryquicklyevenwithinafewhours.
Withthedualmodefeatureyoucan
setuptwodifferentsonarpictures
onthemonitor.Onepictureshows
yournormalsettings,whiletheother
isusedtotestnewsettings,lters,
modes,pulselengths,frequencies,
tiltandotherparametersinorderto
achievebetterperformance.Ifyou
ndbettersetting,yousavethenew
onesettingsasanewpersonalsetting.
Store and Recall
TheSX90sonarcanstore
displaypresentationsmanuallyor
automatically,andyoucanrecall
theselaterforfurtherstudies.Allthe
picturesinthisdocumentarescreen
capturesfromactualsituationsonthe
shinggroundsfromvesselsalready
usingtheSX90sonar.
User settings
Thesonarcanstoreanunlimited
numberofusersettingsfordifferent
shingconditionsanddifferent
operators.Sonarsettingsareoften
personal,andmostcaptainshave
favoritesettingsfordifferenttypesof
shing,species,timeofdayetc.On
theSX90youcanhaveyourfavorite
settingsstoredandnamedjustasyou
like.
Noise lter
Thenoiselterwillsuppress
propellernoise,interferencefrom
otheracousticsystemsonyourown
vesseloronothervesselsnearby.

SIMRAD SX90
Mackerel detection
Theschoolofmackerelisdead
aheadofthevessel.Itcannotbee
seeninthehorizontalview,onlyin
theverticalview.Thetiltindicator
shownintheverticalpicturetellsyou
thatyouneedmoretiltinorderto
seetheschoolinthehorizontalview.
Theschoolisclearlyshowninthe
verticalviewatabout200meteraway
fromthevessel.Theverticalviewis
primaryusedtomeasurethedepthof
theschool.Thisviewisprovidedso
youdonotneedtosaildirectlyover
theschool.Thiswouldscatterthesh,
andbreakuptheschoolinseveral
smallerparts.Theverticalviewthus
makesiteasiertocatchthesh.
Operationalfrequencyis30kHzusing
HyperbolicFMtransmission.
Looking into the seine
“Offcentre”modeisselected
toobtainbetterresolutioninthe
directionoftheschoolinhorizontal
andverticalviews.
TheSX90hasasuperbshortrange
detection.Inthisscreencapturethe
sonarisoperatedwitha300meters
rangesetting,andtheshisnomore
than50metersfromthevessel,as
clearlyseeninboththehorizontaland
theverticalpresentation.Inthetop
righthandcornerallPIdepthsensors
arefullymarkeddownto80fathoms.

SIMRAD SX90
Scattered mackerel detection
TheSX90sonarisoperatedat30
kHz.Thisupperfrequencyisselected
becauseitwillprovidethenarrowest
beam.At30kHz,noothersonars
caninterferwiththeperformanceof
thissonar,evenwithmulitplesimilar
sonarswereoperatinginthearea.
Themackerelcanbeseenasalong
“stripeofsh”aheadofthevesselin
bothhorizontalandverticalviews.
Thewaterdepthis100meter,andthe
echofromapipelinecanbeseenin
theverticalpresentationbehindthe
vessel.
Blue Whiting
Thisscreencapturesshowshow
theSX90hasdetectedaschoolof
BlueWhiting.Therangeisset4500
meters,andthesonardetectstheBlue
Whitingallthewayouttotheendof
therange.

SIMRAD SX90
Tuna
Thissonarpresentationshowsa
schooloftuna.Ithasbeendetected
allthewayoutto2500meters.In
theverticalviewyoucanalsoseea
planktonlayeratabout150meters
depth.Suchlayerscaninsome
casesdisturbtherangedetection
capabilities,andcreateunwanted
echoesasthehorisontalbeamhitsthe
layeratonepointinrange.TheSX90
overcomesthisproblembymeansof
itsefcientlteringcapabilities,and
masksouttheplanktonlayerinthe
samemannerasunwantedsurface
echoes.
Wreck detection
Thisscreencaptureshowsalong
rangedetectionofasunken35.000
toncargovessel.Youcanseeitat
10°portside,itismarkedwithtarget
trackingtriangle.Thewrecklaysat
about100metersdepth.Theother
echoesareshallowbanksinthearea.
Thesonarisoperatedat23kHzusing
“FMAuto”and“NarrowBeam”.The
positionofthevessel,aswellastime
anddate,isindicatedinthedialog
