Page 21: Adjusting The Gain
1. OPERATIONAL OVERVIEW 1.3.7 Adjusting the gain The GAIN control adjusts receiver sensitivity. It should be adjusted to see fish echoes clearly with minimal noise on the screen. Too high a setting not only causes excessive noise on the screen and makes it difficult to discriminate wanted fish echoes but also causes bottom echoes to be painted in strong colors, resulting that the echoes from bottom fish are masked by bottom reflections. -
Page 22: Setting The Tilt Angle
1. OPERATIONAL OVERVIEW Setting the Tilt Angle The tilt angle shows the direction to which the sound wave is emitted. When the sound wave is emitted horizontally, it is said to be zero (0) degrees and when emitted verti- cally, 90 degrees. To set a tilt angle, operate the TILT lever for the desired angle while watching the tilt angle indication at the top right corner of the sonar display. -
Page 23: Bottom And Tilt Angle
1. OPERATIONAL OVERVIEW For example, when the RANGE control, TILT lever and automatic tilt are set to 1000 m, 8° and ±2-10° respectively, the tilt angle changes at each transmission as follows: 8° 10° 8° 6° 8° … Tilt Angle Auto tilt concept 1.4.2... -
Page 24: How To Discriminate Fish Echoes From The Bottom
1. OPERATIONAL OVERVIEW 1.4.3 How to discriminate fish echoes from the bottom The following figure illustrates how two schools of fish (a) and (b) are displayed on screen using three different tilt angles. Case 1: Tilt angle 30 to 40 degrees School of fish is obscured by the bottom echo. -
Page 25: Suitable Tilt Angle
1. OPERATIONAL OVERVIEW sound is reflected just like a light hitting a mirror at a narrow incident angle, it propa- gates away and the sea surface reflections become negligible. However if the sea is not calm enough, they will become dominant and will interfere with observation of wanted echoes. -
Page 26: Finding Range And Bearing To A Target
1. OPERATIONAL OVERVIEW Finding Range and Bearing to a Target Operate the trackball to place the trackball mark on the target you want to measure the range and bearing. The slant range, horizontal range, bearing and depth to the tar- get appear at the upper left corner of the sonar display. -
Page 27: Sonar Menu Overview
1. OPERATIONAL OVERVIEW Sonar Menu Overview This equipment has four menus: sonar menu, sounder menu, marks menu and system menu.

Page 31: Fine Tuning The Sonar Picture
FINE TUNING THE SONAR PIC- TURE Eliminating Unwanted Echoes Echoes from targets such as bottom and fish return to the transducer in order of dis- tance to them, and when we compare their intensities at the transducer face, those from nearer targets are generally stronger when their reflecting properties are nearly equal. -
Page 32: Displaying Surface Fish Clearly
2. FINE TUNING THE SONAR PICTURE proaches. If the color changes suddenly to weaker colors as the fish echo enters FAR and NEAR areas, the TVG is improperly set. Adjust the TVG to correct it. If this again produces sea surface reflections and noise, try to remove them with the AGC and noise limiter as described later on. -
Page 33: Pulse Length
2. FINE TUNING THE SONAR PICTURE 2.3.2 Pulse length The pulse length control determines the length of the transmission pulse emitted into the water. While a longer pulse is advantageous for long-range sounding, it has the disadvantage of being poor in discrimination of targets, i.e., ability to separate several closely located targets. -
Page 34: Suppressing Bottom And Sea Surface Reflections In Shallow Fishing Grounds
2. FINE TUNING THE SONAR PICTURE Suppressing Bottom and Sea Surface Reflec- tions in Shallow Fishing Grounds In shallow fishing grounds with hard or rocky bottom, bottom reflections often interfere with wanted fish echoes and they can not be eliminated sufficiently with the aforemen- tioned TVG and AGC, especially when the tilt angle is large in order to track schools of fish approaching within 400 m. -
Page 35: Rejecting Sonar Interference And Noise
2. FINE TUNING THE SONAR PICTURE Rejecting Sonar Interference and Noise While observing the sonar picture, you may encounter occasional or intermittent noise and interference. These are mostly caused by on-board electronic equipment, engine or propeller noise, or electrical noise from other sonars being operated nearby. 2.5.1 Identifying noise source To eliminate noise effectively, you should first identify the noise source. -
Page 36: Rejecting Interference With Tx Cycle
2. FINE TUNING THE SONAR PICTURE 2.5.4 Rejecting interference with TX cycle When other sonars of the same TX frequency as own sonar are near, an interference ring caused may be displayed. To erase the interference ring from the screen, reduce the TX CYCLE setting. -

2. FINE TUNING THE SONAR PICTURE Choosing Beamwidth 2.6.1 Horizontal beamwidth If you wish to have better bearing discrimination (ability to distinguish two closely lo- cated targets at the same range and different bearings) for schools of fish and also wish to examine the contour of bottom, set [HOR BEAMWIDTH] to [NARROW], on the [SONAR] menu. - Page 38 2.

3. ADVANCED SONAR OPERATION Detecting Schools of Fish Aurally Sometimes you may be preoccupied with other tasks and unable to concentrate on watching the sonar picture. In such cases it would be a good choice to use the audio function. This function enables you to monitor echoes from schools of fish and bottom through the built-in speaker. -

Page 42: Measuring Speed Of School Of Fish
3. ADVANCED SONAR OPERATION Measuring Speed of School of Fish To ensure a good haul, it is important to estimate the direction and speed of the school of fish before shooting the net. You can do this with the FISH key. If the tidal current data is used together with fish speed data, you can determine the timing of the net shooting more efficiently. -

3. ADVANCED SONAR OPERATION Event Mark, Own Ship Position Mark 3.6.1 Event mark The event mark, which requires speed and heading data, is useful for finding the hor- izontal range, depth and bearing to a location some distance from current position. Plotting an event mark on the display is equivalent to dropping a buoy with an anchor- ing chain that extends from surface to bottom. -

Page 61: Interpreting The Display
INTERPRETING THE DISPLAY Bottom Echo When the tilt angle is changed, the bottom echo will appear on the screen. When the tilt angle is decreased, the bottom trace becomes wider and weaker. By observing the bottom condition on the screen, the skipper can prevent the net from being damaged by a reef or a shipwreck. -
Page 62: School Of Fish
6. INTERPRETING THE DISPLAY School of Fish A school of fish appears as a mass of echoes. The color of the mass shows the den- sity. To know the distribution and center point of a school of fish, choose several dif- ferent tilt angles. -
Page 63: Sea Surface Reflections
6. INTERPRETING THE DISPLAY Sea Surface Reflections To reduce sea surface reflections, set the tilt angle to 5° or more so that the upper edge of the sonar beam does not hit sea surface, or adjust the TVG functions. When the sonar is used with a narrow tilt angle, the sea surface reflections cover a large area (up to 300 m to 400 m) as illustrated below. -
Page 64: False Echo By Sidelobe
6. INTERPRETING THE DISPLAY False Echo by Sidelobe An ultrasonic wave is emitted only in the direction set by the TILT lever but, in practice, there are some emissions outside the main beam that are called "sidelobes." Energy of the sidelobe is fairly weak but when the sonar is used in comparatively shallow wa- ter with a hard and rocky bottom, strong target signals are detected by the sidelobe. -
