  • Page 18: Selecting A Display Mode

    Selecting a Display Mode Mode NORMAL HISTORY The CSH-73 provides three display modes: normal sonar pic- ture, echo sounder (E/S) combination, and history display com- bination. Those modes may be selected with the NORM, E/S and HIST keys. Table 2-1 Display mode description The sonar picture appears over the entire screen.

  • Page 19: Selecting A Display Range

    Selecting a Display Range Setting the Tilt Angle Operate the RANGE control to select a display range. The range selected appears at the top center of the screen. The tilt angle shows the direction to which the sound wave is emitted.

  • Page 20: Adjusting The Gain

    Adjusting the Gain Measuring Range and Bearing to a Target The GAIN control adjusts receiver sensitivity (gain). Adjust it so fish echoes are clearly displayed with minimal noise on the screen. Too high a setting not only displays excess noise and makes it difficult to discriminate wanted echoes but also causes seabed echoes to be painted in strong colors, resulting in echoes being masked by seabed reflections.

  • Page 21: Fine Tuning The Picture

    FINE TUNING THE PICTURE Eliminating Unwanted Feeble Echoes This chapter provides the information necessary for tuning the sonar picture. All operations are performed on sub panel 2 (data setting window). Figure 3-1 Display unit Echoes from targets such as seabed and fish return to the trans- ducer in order of distance 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...
  • Page 22 Figure 3-2 Principle of TVG The TVG is also used to suppress unwanted echoes and noise which appear in a certain range area on the screen such as sea surface reflections and cruising noise. To set TVG properly, do the following: How to adjust TVG 1.

  • Page 23: Seabed Echoes

    Suppressing Seabed Tail AGC (data setting window: SIGNAL, SIGNAL PROCESS) The AGC functions to automatically reduce the receiver gain only against strong echoes such as the seabed or a large fish school. Since weak echoes remain unaffected, a small fish school becomes easier to detect.

  • Page 24: Fish Schools

    Suppressing Seabed and Sea Surface Reflections in Shallow Waters WRONG METHOD CORRECT METHOD Rejecting Sonar Interference and Noise Data setting window: TVG•TX, OUTPUT In shallow fishing grounds with hard or rocky bottom, seabed reflections often interfere with wanted fish echoes and they can not be eliminated sufficiently with the aforementioned TVG and AGC controls, especially when the TILT is set to a larger angle in order to track fish schools approaching within 400 m.

  • Page 25: Identifying Noise Source

    Interference from Cruising (propeller) other sonar noise of own ship Figure 3-4 Forms of interference Identifying noise source To eliminate noise effectively, you should first identify the noise source as follows: 1. Turn off the TX switch and operate all on-board equipment one by one while observing the picture.

  • Page 26: Noise Limiter

    Inter- ference Figure 3-5 How CYCLE works Note: When the sonar is used in shallow water with the range set between 60 m and 200 m and Tx cycle at “9”, seabed reflec- tions caused by the 2nd-to-the-last transmission may appear on near ranges.

  • Page 51: Detecting Fish Schools Aurally

    Detecting Fish Schools 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 fish schools and seabed through the built-in speaker.

  • Page 52: The Fish Alarm

    The Fish Alarm The fish alarm sounds an audible alarm when a fish echo above a preset strength enters an alarm zone. You set parameters for the fish alarm at ALM on the data setting window. ON/OFF: Turn alarm on or off. Level: Set echo strength level which will activate the alarm.

To move the own ship mark back to the screen center, press the OFF-CENT key again.

  • Page 54: Comparing Of Fish School Concentration

    Comparing of Fish School Concentration 7-10 You can get an estimate of the volume of two fish schools by using the two ESTIMATE keys. 1. Operate the trackball to place the trackball mark on a fish school, and then press the ESTIMATE 1 key. The estimate mark appears on the fish school.

  • Page 55: Measuring Fish School Speed

    Measuring Fish School Speed Latest fish mark To ensure a good haul, it is important to estimate the direction and speed of the fish school 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.

  • Page 56: The Event Mark

    The Event Mark 7-12 Note 3: Each time the FISH key is pressed the latest fish mark and ship’s speed mark change in the sequence shown below: Fish key pressed once: Fish key pressed twice: Fish key pressed three times: Fish key pressed four times: The event mark is useful for finding the horizontal range, depth and bearing to a location some distance from current position.

  • Page 57: Entering An Event Mark

    Entering an event mark 1. Set the trackball mark where you want to place an event mark (latest event mark). 2. Press an EVENT key. The horizontal range, depth and bear- ing to the event mark appear at the bottom left corner of the screen.

  • Page 58: True Motion Display

    True Motion Display 7-14 The relative motion display places the own ship mark at the screen center, and echoes from fish and the seabed move on the screen relative to own ship’s movement. This means that even when the ship is dead in water, fish echoes move on the display. In the true motion display, however, stationary objects are fixed and own ship and fish echoes move on the display in accordance with their true courses and speeds.

  • Page 59: Plotting Net Location Mark

    Plotting Net Location Mark Before shooting net, you will decide the shoot timing consider- ing the water current direction, distance to fish school and mov- ing direction of the fish school. Use the net location mark as a guide to decide the timing. This function requires speed and heading inputs.

  • Page 60: Setting Distances Between Net Sonde Transmitters

    Setting Distances Between Net Sonde Transmitters 7-16 To accurately display the net shooting mark and net sonde mark position, the distance between transmitters must be correctly set. This is done on the DATA SET menu. Figure 7-14 How to measure distances between transmitters How to set net sonde transmitter distances 1.

  • Page 61: Observing Net Behavior

    Observing Net Behavior With net sonde connection you can observe net behavior after the throwing of the net, on the echo sounder combination mode. Accurate depiction of net sonde position depends on proper set- ting of the distances between net sonde transmitters. You can set those distances on NET SONDE XMTR in the DATA SET menu.

The seabed echo is represented on the screen as a thick line which realistically shows the bottom contour.

  • Page 70: Fish Schools

    Fish Schools Tilt: 40˚ A fish school appears as a mass of echoes on the screen. The color of the mass shows the density of the fishes and the size of the mass how they are distributed. In the following figures, the same fish school is observed with two different tilt angles.

  • Page 71: Sea Surface Reflections

    Sea Surface Reflections Wake As ultrasonic pulses at both edges of the 180˚ sector beam are always emitted horizontally along the sea surface regardless of the tilt angle setting, sea surface reflections appear as a thick line extending across the own ship mark. When the sonar is used with a narrow tilt angle, the sea surface reflections cover an extended area as illustrated below.

  • Page 72: False Echo By Sidelobe

    False Echo by Sidelobe Sidelobe Noise and Interference (A) Interference from other sonar An ultrasonic wave is emitted only in the direction set by the TILT lever, however there are some emissions outside the main beam. These are called sidelobes. The energy of the sidelobe is fairly weak but when the water is comparatively shallow and the bottom is rocky and hard, strong signals are detected by the sidelobe.
