IntendedUse
Raymarinehsb2Series Fishfinders are intended for recreational fishfinding.
The combined Fishfinder/Chartplotter devices are intended for recreational
fishfinding and course chartplotting.The optional chartplotter function is
intendedas an aid to navigation and should not be reliedupon as a substitute
for official navigation charts.
SAFETYNOTICES
This equipment must beinstalled and operated inaccordance with the
instructions contained in this manual.Failure to do so can resultin personal
injuryand/or navigationalinaccuracies.Inparticular:
1.HIGH VOLTAGE.The LCD display unit contains high voltages.
Adjustments requirespecialized service proceduresand tools onlyavailable
to qualified service technicians – there are nouserserviceable parts or
adjustments. Theoperatorshouldneverremovethedisplayunitcoveror
attempttoservicetheequipment.
2.NAVIGATION AID. The chartplotterunit is only anaid to navigation. Its
accuracycan be affected by manyfactors, including equipment failureor
defects, environmental conditions, andimproperhandling or use.It is the
user’sresponsibility to exercise commonprudence and navigational
judgements.This unit should not be relied uponas a substituteforsuch
prudenceand judgement.

Introduction
Chapter1: Overview
1.1 Introduction
This handbook describes the following hsb2(High SpeedBus) Series
Fishfinder displays:
Raymarinehsb2SeriesFishfinders use the latest processorand sonar
technologyfor accurate performance and echo detection. Units feature 7" or
10.4" daylight viewable monochrome or color LCDdisplays andthe
Raychart(RC) models include a full C-Map NT Chartplotter. With up to 600
watts output power and dual frequency operation, hsb2SeriesFishfinders
provide performance from 1 up to 3000 ft. In fact, the L1250 Plus and
L1250RC Plus units offer1000 watts power and a depthrangeup to5000 ft.
UsetheHigh Speed Bus(hsb2), SeaTalk, and NMEA interfaces to provide an
integrated system with additionaldevices, such as Pathfinder Plus Radar,
RaymarineAutopilot,and RaystarWideArea AugmentationSystem
(WAAS) GPS products.
Connectingan hsb2SeriesFishfinder to an hsb2Series PathfinderPlusRadar

displayed on all three units. Similarly, chart data can be repeated on a
fishfinder-onlydevicefromanyviahsb2fromanyotherhsb2devicewithchart
capabilities.
This handbook describes the display unitcontrols and details both fishfinder
and chart operations. Controls that are specific to either fishfinder or
chartplotterare described in fishfinderor chart sections/chapters.

Introduction
HowtoUseThisHandbook
If youare installing thedisplay system yourself, you should read Chapter 2
before you startthe installation. This chapter also provides information that
will beusefulifyou areconnecting your hsb2Seriessystem to other
equipment.
Foranoverviewofthedisplayunitcontrols,thefishfinderandthechartplotter
systems, read Chapter 1.Chapter 3will helpyou start using your system.
For detailed information on fishfinder operations refer to Chapter 4.
Forchartplotteroperatingdetails,refer to Chapter 5 andChapter 6.
To changethe system setup defaults, readChapter 7.
Chapter2 provides planning considerations and detailed instructions for
installing the fishfinderdisplay unit. It shouldbe referred towhen youare
ready toinstall the system. Details to connect the display to other equipment
via hsb2, NMEA,and SeaTalkare alsoprovided.
Chapter3 explains how to start using thedisplay and describes how touse
some of the basic fishfinder and chart functions. Chapter 3 also provides
operating guidelines for typical chartplotter scenarios; theseguidelines
introduceyou to many of the chartplotter functions.
Chapters4provides detailed operating information forthe fishfinder
functions-selectingdepthrangelimits,adjustinggain,colorandSTC,setting
alarms, using the VRM marker, marks andman overboard.
Chapter5 provides detailedoperatinginformationforthestandard
chartplotter functions -using chart cards, plotting waypoints and routes,
followingroutes and showing tracks.
Chapter6providesdetailedoperatinginformationforfurtherchartfunctions,
includingmeasuring distances, man overboard andcursor echo. It includes
instructions forsetting up a differential GPS.
Chapter7 provides instructions for setting up your system to suit your
preferences. You should read this chapter to determine how to set up the
fishfinder and chartplotter system defaults.
Chapter8 provides information onuser maintenance, and what to doif you
experience problems.
The Appendices provideadditional information thatyou mayfind useful:
AppendixAlists the technical specificationsfor the fishfinder and for the
chartplotter.
AppendixBprovides details on connecting the display unit to specific GPS
systems.

Transducer
Thehsb2Series Fishfinders require a transducer, either thru-hull, in-hull, or
transom-mount.
Transducers can measure water depth, temperature, distance traveled, and/or
speed.It isimportant to position your transducer correctly. For detailson
transducers, including locationand installation instructions, see document

Introductionto
hsb2Systems
Introductiontohsb2Systems
Thehsb2(High Speed Bus)connection enablestransfer of data among
compatible units. For example, fishfinderdata is transferred from the
fishfinder (themaster display) via the hsb2connection and can bedisplayed
andcontrolledon anyother hsb2series LCD or CRT display(the repeater
display).However,ifyouchange,say,depthrangeononedisplay,itaffectsall
displaysshowingfishfinderorfishfinder/chartoverlay.
In particular, you canconnectyour hsb2Series Fishfinder to aremotehsb2
Series Pathfinder PlusRadar and then to a remotehsb2Series Chartplotter to
provide fishfinder, chart, and radar functionality on all three displays.
Full functionality of the fishfinder isachieved when itis part of an integrated
system, with other equipment (in addition to other hsb2units) connected via
SeaTalk orNMEA 0183. Datafrom this equipment including positionand
heading is displayed on thedisplay and is used incalculations.
Itispossibletoconnectto up toeighthsb2series LCD orCRT displays to
provide an integrated system. Earlier HSB (non-Plus) Displayunitswith can
be upgraded to provide hsb2compatibility.Please contactyour authorized
Raymarinedealerfordetails.
Thehsb2systemcanincludeseveralchartplotterdisplays,eachwithtwochart
cartridge slots.Each display can access twolocal and upto six remote chart
cartridges.Chartscanbecontrolledindependentlyoneachdisplay,evenwhen
a remote chart cartridge isbeing used. Details on connecting the equipment
are given in Chapter 2.

OperatingModes
The following are features of the combined Fishfinder/Chartplotter units:
•Displayschart information from the C-MAP NT®chart cards (C-Cards)
•Three full-screen operating modes: Fishfinder, Chart, DataLog (if appro-
priate data is available)
•View fishfinderand chart simultaneously
•Choice ofchartorientation: Head Up,Course Upand North Up
OperatingModes
If youhave acombined Fishfinder/Chartplotterunit, or have anhsb2Series
Chartplotter connectedtoa Fishfinder, three full-screenmodes–fishfinder,
chart and data log are available; you selectthe operating modeusing the
DISPLAY key as described in Chapter 3.
YoucanalsosetWindowsOntosplitthedisplayintotwohalf-screenwindows
toshowsupplementarydata,ortodisplayfishfinderandchartsimultaneously.
The main operating mode(fishfinder orchart) is displayed inthe upper
window;you choose what is displayed inthe lower window.
In addition, if you have an hsb2Series PathfinderPlusRadar display
connected,you can setthe display to radar mode; this provides similar
functionality toa combined Pathfinder Radar/Chartplotter.
If youonly have an L760Plusor L1250Plus fishfinder-only unitconnected,
onlyfishfindermodeis available.

1.2 TheFishfinderDisplay
When youfirst turn the display unit on and select fishfinder mode, the
scrolling bottom graph is displayed. This isa graphicalrepresentationof the

left and becomes arecordof the echoes seen.A typical display isshown in
Figure 1-2.
The images at the right handside of the display arethe mostrecent echoes.
Some echoes indicatefish,and others show thebottom. It can also indicate
bottom structures,such as a reef or shipwreck. The upper and lower depth
range limits areshown.
The fishfinder screen includes a status bar that displaystransducer frequency
and indicates which auto settings areenabled(Gain,Color Gain, Range,
ZoomandFrequency),andalarmstatus(fishandshallow/deepwaterdepths).
You can customize thefishfinder by choosing what isdisplayed and howit is
displayed(including language andunits). For example, youcan set the scroll
speed ofthe bottom graph display, and youcan select the range to adjust the
amountofdetaildisplayed.
Youcanviewthe cursorpositionandavarietyofdata(suchasspeed,heading
and depth) fromthe transducer and other equipment in user-selectabledata
boxes.These data boxes can be moved aroundthe screen andthey can be
switched on or off.
