Introduction INTRODUCTION The purpose of this manual is to provide the information and procedures required for safe and efficient use of the Simrad SH80 Fish finding sonar system. A thorough understanding of system functions and controls is necessary to optimize overall performance. Sonar conditions vary, sometimes drastically, and it is not possible to identify settings that will provide the best data at all times.
Simrad SH80 Important matters As with all advanced instruments, there are a few important matters about the SH80 that you must remember. Before you switch on the sonar When you power up the sonar, the transducer is lowered down below the vessel’s hull. Make sure that you have sufficient water depth before you do this! When the sonar is not in use To protect the sonar when it is not in use, we strongly advice you to hoist the transducer, even though you may not switch off the power.
Introduction Basic information The Simrad SH80 Fish finding sonar is an omnidirectional high frequency sonar, designed for all sized fishing vessels, both purse seiners and trawlers. The standard frequency is 116 kHz (multiple frequencies as option), and the beam can be electronically tilted from +10 to –60 degrees. Great emphasis has been placed on giving the best possible presentations on a high resolution colour display.
Simrad SH80 Main units The Simrad SH80 Fish finding sonar consists of the following units: • Normally installed in the wheelhouse: – Display monitor – Operating Panel – Processor Unit – Interface Unit • Normally installed in the sonar room: – Transceiver Unit – Hull Unit Wheelhouse units The Display Monitor is a high-resolution colour LCD (Liquid Crystal Display). In addition to the sonar picture, the monitor can also display the user menu for the interactive operation.
Introduction Note Note that SH80 sonars shipped before August 2003 use a different Processor Unit; the APC10. These sonars do not have the Interface Unit fitted. All interfaces to peripheral equipment are then handled by the APC10. Sonar room units The Transceiver Unit is located in the sonar room, close to the Hull Unit. One signal cable is used for communication with the Interface Unit in the wheelhouse.

Introduction Basic functionality The basic principles of the Simrad SH80 Fish finding sonar are unique because of the 240 transmitter and 480 receiver channels with their transducer elements spread around on the cylindrical transducer array. The transmission, reception and data processing are under computer control, and the powerful capabilities of the sonar are the results of sophisticated digital signal processing software and state of the art hardware.
Simrad SH80 Figure 3 60 degrees vertical slice This vertical slice, which is presented by the white audio line in the horizontal picture, can be selected to any bearing by the manual training control. The combination of the Omni mode and the vertical slice will give an optimal visualization of the catch situation.
Introduction In addition to the Omni picture, the vertical slice is especially useful for visualizing the vertical distribution of a school of fish. In that way, it is not necessary to go over the target to see the distribution on the echo sounder, which often results in a spreading of the school. Stabilization system When the beam stabilizer is activated, both horizontal and vertical beams will be stabilized electronically for roll and pitch movements up to ±20 degrees.
Simrad SH80 interference, noise and reverberation. In addition to giving a clean and stable echo presentation, this will normally also increases the sonar’s detection range. Frequency selection (Option) The optional multiple frequency selection can be used for suppression of interference from other sonars. However, the sound absorption in salt water increases with the frequency, thus giving the lower frequencies a longer detection range.
Introduction controlled parameters include power output and time delay for each transducer element in order to form a beam with the selected tilt angle. When the stabilization system is active, the tilt angle for each beam will automatically be corrected relative to the vessel’s pitch and roll movements. Optional functionality The standard Simrad SH80 Fish finding sonar is a single 116 kHz version with beam stabilization. The beam stabilization was an optional function until 1 January 2003.
Simrad SH80 In addition to log and gyro, the following peripheral equipment can be connected to the sonar: • A (D)GPS may be connected to the SP70 sonar to establish the vessels position and provide cursor and marker latitude and longitude. • Simrad echo sounders (EQ, ES and EK Series) provides a bottom plot on the catch data page. • Simrad PI32, PI44 and PI54 Catch Monitoring systems provide the net depth in digits and bars on the catch data presentation.
Introduction SW 1.2.X Beam function added to the Horizontal menu. Dead reckoning function implemented on the Setup menu. The TX Power function is changed to have the power switched off when the sonar is powered up. The Mode buttons on control panel can be used to choose operational modes or operator setup. The PP Filter has been improved. User configurations can be stored and retrieved. The Fish alarm function was added to the Setup menu. Dual 2 operational mode added.

Simrad SH80 DISPLAY MODES This chapter describes the Simrad SH80 display modes. The various modes represent the graphical presentation of sonar data. Several display modes are available to present the best possible presentations as well as flexible choices for a large range of user applications.
Display modes Bow up When Bow up mode is selected, the vessel symbol is stationary on the screen with the bow pointing upwards. The echo presentation covers 360 degrees around the vessel, and all echoes are updated for every ping. The distance from the vessel symbol to the outer echo ring is equal to the selected range. Figure 15 “Bow up” display mode The movement of the echoes across the screen are controlled by a combination of the vessel’s course and speed and the target’s own movements.
Simrad SH80 North up When North up mode is selected, true north is always up on the screen. The vessel symbol is stationary with the bow pointing in the vessel’s course direction. The movement of the echoes across the screen are controlled by a combination of the vessel’s course and speed and the target’s own movements.
Display modes True motion When True motion mode is selected, the picture is locked to a geographical position, where the vessel moves around the screen according to its present course and speed. All echoes are always presented in their correct position relative to the vessel, and their movements on the screen will be a true representation of the movements of the targets through the water.
Simrad SH80 Bow up/Audio When Bow up/Audio mode is selected, the upper half of the screen shows a 180 degrees bow-up presentation, while the lower part is used for a recording of the audio channel. Figure 18 “Bow up/Audio” display mode The audio channel is shown with a continuous white line in the horizontal picture, and it can be trained in any direction. The recorded echoes are a direct replica of the echoes under the white audio line.
Display modes 270°/Vertical The 270°/Vertical mode is specially designed for purse seining. The vertical half slice is displayed in the lower left corner for normal setting with the net on the starboard side. If the net is set on the port side, the 60 degrees vertical slice will be displayed in the lower right hand corner.
Simrad SH80 Bow up/Vertical When Bow up/Vertical mode is selected, the picture is divided into three sections; where the left side is a bow-up presentation similar to the Bow up presentation previously described. Figure 20 “Bow up/Vertical” display mode The upper part on the right hand side is a Catch data presentation, while the lower part is a 60 or 90 degree (optional) Vertical slice presentation.
Display modes True motion/Vertical When True motion/Vertical mode is selected, the picture is divided into three sections; where the left side is a True motion presentation similar to the true motion presentation previously described. Figure 21 “True motion/Vertical” display mode The upper part on the right hand side is a Catch data presentation, while the lower part is a 60 or 90 degree (optional) Vertical slice presentation.
Simrad SH80 Dual 1 The Dual 1 mode is a kind of “two sonars in one” operation, where each presentation is updated for every second transmission. All settings can be set individually for each of the two presentations. This makes the dual mode especially useful for optimizing settings by directly comparing the two presentations. Figure 22 “Dual 1” display mode To optimize the horizontal settings, use the Horizontal menu to try different settings in the upper picture.
Display modes Dual 2 The Dual 2 mode is very similar to the Dual 1 mode previously described, but the “two sonars” are presented next to each other. All settings can still be set individually for each of the two presentations.

Menu descriptions MENU DESCRIPTIONS This section provides a detailed description of the complete menu system for the Simrad SH80 Fish finding sonar system. The chapter Menu structure gives a description of the menu system configuration with references to more detailed descriptions of all the menu. Any selections you do in the menus will bring up the parameters available for the chosen setting.
Simrad SH80 About the menus The Simrad SH80 Fish finding sonar comprises a large number of different menus on several levels. Menus are selected by pressing their respective tabs on the right hand side, and the appearance of menus and tabs depends on the chosen operational mode and the current settings. The menu types are organised as follows: • Active menus: Relevant for each of the display modes, available at all times, can be selected by the appropriate tab.
Menu descriptions Horizontal menu The Horizontal menu is used to control the horizontal presentations. The parameters chosen are present in all display modes. When a horizontal parameter setting is selected and defined in one mode, the chosen settings will automatically be applied to all modes. The Horizontal 2 menu is identical to the Horizontal menu. It is used during Dual 1 and Dual 2 operations. Buttons Range: Select the range for the horizontal presentation.
Simrad SH80 Frequency: On the SH80 you can alter the sonar’s transmission frequency. This is very useful to eliminate interference from other equipment on board, or from other vessels in the vicinity. (► Frequency on page 122) TVG: Time Varied Gain. This function will automatically adjust the gain in the sonar to compensate for geometric spread and absorption. Note that the TVG will only work within the first 1000 meters.
Menu descriptions Vertical menu The Vertical menu is only shown in modes with a vertical slice function. All relevant settings, except the TX Power, can be selected separately for the vertical modes independent of the horizontal settings. When any vertical setting is selected and defined in one mode, the setting will be applied to all vertical modes. Buttons Range: Select the range for the vertical presentation. (► Range on page 141) Bearing: Use this function to adjust the bearing.
Simrad SH80 RCG: Reverberation Controlled Gain. This function will automatically remove unwanted reverberation from the bottom or from the sea surface. It may however also remove scattered fish. (► RCG on page 143) PP Filter: The Ping-to-Ping filter will only show you the echoes if they are still present after several consecutive pings (2, 4 or 8). This function will provide you with a more stable echo presentation, as spurious echoes will be suppressed.
Menu descriptions Resolution: Select 16 or 64 colours in the display presentation. The chosen resolution is shown in the colour bar below the button. Panel Backlight: This function controls the intensity of the backlight in the Operating Panel. (► Panel Backlight on page 137) Mode buttons: Use this button to choose how the Mode buttons on the Operating Panel shall work. You can either choose between the four most frequent modes, or the four most frequent user settings.

Basic theory BASIC THEORY This chapter explains some of the basic theory related to settings, error sources and noise conditions. Topics Settings on page 171 Noise and reverberation on page 175 Layers and deflections on page 177 Settings A sonar will transmit a sound wave into the water around the vessel. When this sound wave hits fish, bottom, or other objects in the water, a part of the sound will be returned as echoes.
Simrad SH80 When you choose the TVG setting you can either switch it off, or choose a “X log R” value. The different settings determine how much gain the sonar will use as time elapses along the X-axis. A higher value for “X” will make the angle (C) steeper. Default setting on the SH80 sonar is 20 log R. What is the PP Filter? PP Filter means “Ping-to-Ping Filter”. When this function is activated, the sonar will compare the echoes from one ping with the echoes from the next pings.
Basic theory Figure 30 Beam widths: Wide (A), Normal (B) and Narrow (C) (CD015005A) A B C Default setting on the SH80 sonar is Normal. This setting is basically designed for longer ranges. You may also try setting Auto. This setting will automatically adjust the beam width depending on the current range. About Gain You can adjust the gain in many different ways, but the most important is the setting made by the Gain buttons on the Operating Panel and on the Horizontal and Vertical menus.
Simrad SH80 The RCG will remove unwanted echoes from the sea surface and the bottom. If you select a strong setting the bottom echoes will disappear altogether if the bottom is flat, while schools of fish close to the bottom will be easier to see. Note that scattered fish may be more difficult to spot if the RCG function is active, as these can be misinterpreted as reverberation. It is therefore important that you use the RCG with great care if your are searching for scattered fish.
Basic theory Noise and reverberation Every time you use the sonar the quality of your search operations will depend on numerous error sources caused by the natural environment and physical properties of your vessel. We distinguish between the two terms noise and reverberation. • Noise is generated by the vessel: engine, propellers, winches, refrigerating plants etc. • Reverberation is caused by natural conditions in the sea: temperature, salinity, sea state and bottom conditions.
Simrad SH80 The echoes from the bottom will vary with how uneven the bottom is, what kind of bottom you have under your vessel, (rock, mud, sand etc.) as well as your current tilt setting. The echo from the sea surface will vary with the current sea state and your current tilt setting. The illustration demonstrates how the bottom and the sea surface return echoes back to your sonar transducer.
Basic theory 2 Switch the equipment on again one at the time, and check the sonar every time. With luck, you will spot which of your electrical systems that create the noise. To deal with the problem, consult your dealer and/or a certified ships electrician. Layers and deflections Your sonar operations may also be disturbed by environmental situations that you are unable to control.
Simrad SH80 Figure 34 Water temperatures on warm days B A (CD015005G) When the temperature decreases (A) closer to the bottom, the sonar beam is deflected down as indicated by the illustration. The school of fish (B) you thought you would see is not visible at all. On cold days, you may experience the opposite: the cold water will be close to the surface, and the water temperature increases with increasing depth.
On-board maintenance ON-BOARD MAINTENANCE This chapter deals with maintenance work that you may carry out on board. In addition to cleaning the cabinets and dust filters, you should inspect the sonar room at least once a week. The ventilation and heating system, as well as the bilge pump arrangement should then be checked to be in good working order. For location and replacing of fuses, refer to the chapter for the unit in question.
Simrad SH80 Preventive maintenance schedule The Simrad SH80 is a state of the art sonar system with only a minimum of moving parts.

Provided with two power buttons, a red button to power off the hull unit, and a green button to power it on.
Simrad SH80 Hoisting and lowering from the sonar room In case of failure in the normal hoist/lower operation controlled from the Operating Panel, or for maintenance purposes, the transducer may be hoisted and lowered from the sonar room. Three different procedures may be used. Caution In the event of improper operation, the powerful 3 kW electric motor may cause serious damage to the equipment and/or injury to personnel.
On-board maintenance Hoist/lower contactors K301 and K302 If the 3-phase voltage for the hoist/lower motor is available, the transducer can be hoisted and lowered by operating the hoist (K301) and lower (K302) contactors in the Motor Control Unit by activating the small switch handle on the front of the contactor.
Simrad SH80 Manual hoist and lower with hand crank 1 Locate the motor overload switch S301 in the Motor Control Unit, and press the red button marked 0. 2 Locate the hand crank in the Motor Control Unit. 3 Remove the plastic plug on the top cover of the Hull Unit, and mount the hand crank onto the stub shaft through the hole in the top cover. 4 Use the hand crank to hoist and lower the transducer.
On-board maintenance Motor overload switch To prevent the hoist/lower motor from overload, an overload circuit breaker S301 is located in the Motor Control Unit. This may automatically be switched off during hoisting if the vessel’s speed is too high, or if the transducer shaft has been bent.
Simrad SH80 Docking the vessel When docking the vessel, great care must be taken not to damage the sonar trunk and protecting blister. WARNING The sonar must never be powered up when the ship is in dry dock. The transducer will be damaged if it transmits in open air. To prevent inadvertent use of the sonar, set the main on/off switch on the Processing Unit to Off, or disconnect the mains power, whenever the vessel is in dry dock.
On-board maintenance 1 Ensure that the water depth below the vessel is sufficient to lower the transducer array. 2 In the Motor Control Unit, set the mode selector switch S302 to position HOIST, and then to position STOP. 3 Set the mode selector switch S302 to position LOWER. 4 Observe that the transducer array is lowered down into the water. • The hoist/lower motor will automatically stop when the transducer shaft reaches the lower limit switch.
Simrad SH80 Cleaning the transducer The transducer normally needs little attention. However, the transducer face should be inspected and cleaned when docking. Note Do not paint the transducer array with traditional hull plating paint. Use only the correct type of paint approved by Simrad. Do not use metal tools or high pressure water on the transducer array. Observe the following procedure.
On-board maintenance • If you wish to ensure that the array is not lifted inadvertently, remove the hand crank from its storage position in the Motor Control Unit. This will disable the S302 control switch, and the array can not be hoisted at all. 6 Perform a thorough check of the transducer array. If necessary clean the array. • To clean the array, use normal synthetic soap and water. • To remove marine growth, use fine-grade sandpaper or emery paper. • Do not use strong solvents.
Simrad SH80 Air bleeding In order to protect the inside of the installation trunk against corrosive attacks, the air bleeding system must be operational. This system consists of a small air bleeding cock on the top of the mounting flange and a pipe leading up and above the sea water level. The pipe allows air to escape from the trunk. Figure 47 Location of the air bleeding cock The air bleeding system must be checked after the ship has been docked. Observe the following procedure.
On-board maintenance Hull unit lubrication The hull unit is fully lubricated when it is installed on the vessel, and this is also checked during installation. During normal conditions, the lubricants applied will last for a long period of time. Note Additional lubrication of the hull unit must only take place when it is required. 1 Observe the following procedure. The numbers refer to the lubrication points on the illustration.
