INSTALLATION AND OPERATION
PARTA: INTRODUCTION
Scanning sonar has many applications in commercial
fishing, pleasure boating, sport fishing, navigation,
diving and salvage, underwater security, and a host
of other uses only now being developed. The HD800
series is designed for easy operation, and you will be
able to learn how to use your sonar quickly.
PART B: YOUR NEW SONAR
WESMAR’s new HD800 series sonars have the most
advanced technology of any marine electronic equip-
ment on the market today, technology specifically
designed to help you make more money.
With anewlydesignedscreendisplay, specialfeatures,
and four options menus, the HD800 sonars provide
moreinformationabout thetargets you’reafter soyou
can make the kind of catches you want—profitable
ones. The high-definition sonar screen offers four
times the picture resolution of older models, which
means you get a truly accurate presentation of what
is in the water before and around you.
New features boost the effectiveness of the HD800
series and make your job easier. Front panel gain
controls are digitally displayed on the screen for
easy reference. Scanning speed can be increased
or decreased instantly from the front panel enabling
you to track fast moving fish. Adjustable thresholds
and pulsewidth give added bottom discrimination.
The four options menus were designed for the setup
of your new sonar. After installation, on your first
time out with the HD800, you can make many small

SONAR OPERATION
WESMARisfamousfordesigningsonarsthatareeasytooperate.
The HD800 Series follows this tradition by having a minimum
of controls. In addition, the HD800 series is the world's most
advanced sonar. The technician or operator can customize the
sonar to suit water conditions and fishery by selecting different
sonar parameters in menu.

Page 12 WESMAR
HD800
PARTA: OPERATION
Like all sophisticated computer equipment, the
HD800 series sonar has temperature limits of 0
degrees C (32 degrees F) to 43 degrees C (110
degrees F).
THESONARSHOULDBEOPERATEDONLY
WITHIN THESE TEMPERATURE LIMITS.
TheHD800hasan internalmemorythat willremember
allthe specialsettings youhave selectedforyourfish-
ery. This internal memory will retain all your settings
even when the sonar is turned off. There is a remote
possibility the settings may return to the default set-
tings if there is a power surge. If this happens, turn
the sonar off, wait a few seconds, and turn it back on.
Reset your special settings as before.
The HD800 sonar is like having two sonars in one;
one part scanning horizontally, the other scanning
vertically. With two separate operations, each has its
ownindividual controls. Whenscanninghorizontally,
the adjustments are set for sonar operation. When
scanning vertically, the adjustments resemble that
of a sounder. When the sonar moves back and forth
between the two operations, all preset adjustments
also switch back and forth.

INSTALLATION AND OPERATION
PART B: CONSOLE CONTROLS
The HD800 is a multi-option sonar designed for easy
operation and interpretation. Following are some
simple instructions and guidelines to help tailor the
HD800 to your fishing or navigational needs.
1.0 POWER
To turn on your sonar, push the POWER Button. When
power is applied the following will occur:
1.1 The monitor will show the system test screen for
10-20 seconds.
1.2 The Hoist Down light will turn red if the hoist
switch is in the down position.
1.3 Thecoolingfan, locatedon the consoleback panel,
will start to spin.
1.4 The console front panel lights will illuminate, vis-
ible under low light conditions.
During this period the sonar performs a system test. When
all the functions are operational, the screen will display:
SYSTEM TEST PASS
If other messages are displayed, consult your dealer or
WESMAR.
In addition to system test, the version of the software is
also displayed.
2.0 HOIST
The HOIST Switch raises and lowers the soundome.
If the HOIST Switch is in the down position, the
soundome will lower when the console is turned on
and raise when the console is turned off.

When the sonar is on, the soundome can be retracted
by moving the HOIST Switch to the up position. This
isuseful whenoperatingthe sonarinthesoundermode
without extending the soundome.
2.1 Hoist Down Light
When the Hoist Down Light is on, it indicates that the
soundome is in the down position. This light serves as
a warning. The light must go off when the soundome
in retracted.
3.0 VOLUME
This control is used to raise and lower the volume
of the external speaker. Sound is proportional to the
echo strength of the target displayed on the screen.
Also, weak targets below the preset threshold can be
heard when volume is turned up.
4.0 BRIGHTNESS
The BRIGHTNESS Control allows you to adjust the
intensity of the sonar display. For nighttime view,
WESMAR recommends dimming all the white text
and removing the blue background color. See Menu
#3, this page. Note: If brightness knob is turned
completely CCW, the video will still come on during
self test, but then fade to a black screen. Simply turn
the brightness knob CW to the desired brightness.

7.0 TILT
7.1 Tilt, Sonar
The TILT angle of the sonar soundbeam can only be
changed when the soundbeam is scanning in sonar, full
or split screen. When the soundbeam is in the sonar
mode, the TILT switch will move the transducer from
4degreesabovehorizontalto-90degreesvertical.TILT
angle is displayed in the TILT Box located on the left
of the screen.
Note: TILT reading will go blank when scanning the
bottom,inprofile, andtaking avertical scan(thickness)
in sonar.
7.2 Tilt, Profile
TheTILTSwitchhasasecondfunction.Whenthesound-
beam is in the profile mode, the TILT Switch selects the
size of the Profile Sector. By pushing down on the TILT
Switch, the profile sector will reduce approximately 10
degrees for each toggle. Pushing up on the TILT Switch
increases the profile sector.
8.0 BEARING
8.1 When operating in full screen sonar, 360 degree
scan, the BEARING Knob will position a BEARING
line around the screen. Relative BEARING to a target
can be determined by positioning the BEARING line
over the target. Relative BEARING is displayed in the
SCAN box to the left of the screen.
8.2 When scanning a sector in sonar, the BEARING
Knob will move the sector clockwise or counterclock-
wise around the screen. The BEARING line marks the
center of the sector.
8.3 When vertically scanning a school of fish for a
thickness view, the BEARING Knob will reposition
the vertical scan. Move the BEARING line over the
target to view the thickness. The leading edge, center
and tailing edge of a school can be profiled to validate
density.

INSTALLATION AND OPERATION
9.0 CURSOR
The CURSOR POSITION Switch moves the square shaped
CURSOR up, down, left and right.
Horizontal range and depth of a target can be determined
by placing the cursor over the target. Range and depth are
displayed to the center right of the screen.
10.0 SECTOR
10.1 SECTOR Knob
The SECTOR Knob lets you choose the size of the area
to be scanned in the sonar mode. Sonar SECTOR is
centered on the bearing line. Moving the bear line will
move the SECTOR.
10.2 Manual Position
Manual position will stop the soundbeam from scan-
ning. This stationary beam can be positioned with the
BEARING Knob and in tilt with the TILT Switch.
10.3 FullScreen BottomProfileorFullScreen
Sounder, Selected in Menu 1.
10.3.1 BOTTOM PROFILE will scan the
soundbeam across the bottom. Fish close to the
bottom, contours and sea bed composition, will
be displayed across the screen. By using the Tilt
Switch, the PROFILE can be sectored down or up
in 10 degree increments.
10.3.2 SOUNDER will tilt the transducer auto-
matically down to 90 degrees and rotate in bearing
to 90 degrees. At this position the soundbeam is
stabilized for vessel roll providing excellent fish
detection off the bottom.
10.3.3 SOUNDER-SIDESCAN
When operating in the SOUNDER mode, both
Tilt Switch and Bearing Knob will reposition the
soundbeam in any degree of bearing and tilt.
Forexample: IfyouwanttoSIDESCANtheshore

Page 18 WESMAR

to port, position the soundbeam to 270 degrees
bearing with the Bearing Knob and tilt with the
Tilt Switch. As the vessel parallels the shore, all
targets between the vessel and shore will mark on
the SOUNDER DISPLAY.
11.0 TRACK - VERTICAL
PROFILE SWITCH
11.1 TRACK
To TRACK a school of fish, the HD800 console must
be connected to a GPS unit with NMEA0183 output.
The sentence format recognized by the HD800 is RMC
and GLL, VTG. This format includes; time, latitude,
longitude, speed over ground, course over ground and
date. All this information is used to track and log each
track into menu 4.
NOTE:TherearemanyGPSmodelsonthemarketrang-
ing in speed and reliability.All GPS units give latitude,
longitude,and calculateheading. Headingis calculated
between two or more GPS updates. Because bearing
is a calculation, the greater the distance between GPS
readings, the more accurate your heading will become.
WESMARrecommendsa vesselspeed offour knotsor
greater,withnocoursechangeduringthetargetmarking
phase. Once tracking is engaged, the vessel may then
pursue any course.
To TRACK fish detected in the sonar mode, place the
cursor over the fish with the Cursor Position Switch.
Immediately lift up the TRACK SWITCH. When the
TRACK SWITCH is clicked up for the first time, the
HD800 console will calculate the GPS location of the
fish, which it holds in memory. When the GPS location
is calculated, the fishlupe to the right of the screen will
disappear.
Continue to sweep the target. When noticeable move-
ment of the school is detected, mark the target for the
second time with the cursor. Immediately lift up the
TRACKSWITCH. Tracking is engaged when the fish

icons start to move to the right of the screen. Informa-
tion as to: range to the fish and bearing to the fish from
the vessel will be displayed in the fish box to the right
of the screen. Also, speed and direction of the fish is
displayed in the lower half of the fish box.
When tracking is engaged, range and bearing will dis-
play on a green background for 10 minutes. After 10
minutes the background will change to yellow, also for
10minutes.After10minutesof yellow,thebackground
will change to red. When twenty minutes have passed,
tracking will stop. Caution: The computer cannot ac-
commodate the uncertainty of fish travel or affects of
water currents.
This color change over time is to alert the operator that
theexpectedpathorcalculatedpathofthefishmayvary,
due to change in direction or speed of the fish.

11.2 VERTICALPROFILE(THICK-
NESS)
As the soundbeam in sonar passes through a school of
fish, push down on the TRACK SWITCH. An overlay
screenequaltoafourthofthescreenwillshowavertical
profile or thickness of the school of fish.
When vertically scanning, the BEARING KNOB will
repositionthe verticalscan. Bymoving thebearing line
over the target, the vertical profile view will show the
thickness of the leading edge, center and trailing edge
of the school of fish.
VERTICAL PROFILE starts at 0 degree tilt and steps
the transducer in 1.8 degree increments in the vertical
plane down to -90 degrees. To sector the profile for fast
target update, press up on theTILT SWITCH. The sec-
tor will move up from the vertical in 10 degree steps.
