Each time the range is changed the newly selected range appears in large characters for five seconds at the top of the sonar display.
  • Page 19: Adjusting The Gain

    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 20: 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 vertically, 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 21 Range (m) 50, 85, 100, 150, 200, 250, 300, 350 400, 450, 500 600, 800 1000, 1200, 1600 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: 1.
  • Page 22: Bottom And Tilt Angle

    1. OPERATIONAL OVERVIEW 1.4.2 Bottom and tilt angle Finding the proper tilt angle is of utmost importance when searching for fish, especially in coastal water fishing, where the depth of the fishing ground is from 50-100 m. In this type of fishing ground it is imperative that the bottom echo be always displayed to properly distinguish between fish and the bottom.

    5-6 degrees so that the upper portion of the beam becomes almost parallel with the sea surface. When the sea is rough, it is often set to a little larger angle. * 15° for CSH-5L, 13° for CSH-8L Tilt angle and surface fish (example: CSH-5L) Sea surface...

  • Page 25: Sonar Menu Overview

    Sonar Menu Overview This equipment has four menus: sonar menu, sounder menu, marks menu and system menu. Of the four menus, the SONAR menu is the one you will use most often. Note that the gain and range cannot be adjusted while the menu is displayed. 1.6.1 Operating procedure 1.
  • Page 26: Sonar Menu Description

    1. OPERATIONAL OVERVIEW 4. Use the [RANGE] control to choose a menu item. The selected item is highlighted. Note: Items displayed in red are locked to prevent accidental change of setting. When any of those items are selected the display shown below appears, to ask you if you are sure to change the setting.
  • Page 27 Description of sonar menu (con’t from previous page) Item COLOR Adjusts color level against strong reflections. The higher the setting, the more the red color is RESPONSE displayed and weak level colors are displayed as is, thereby giving the appearance that the gain has been raised.

  • Page 29: Fine Tuning The Sonar Picture

    The CSH-5L/CSH-8L incorporates two TVG functions, NEAR and FAR, and they mainly compensate for propagation loss on short and long ranges respectively, centered at the ranges shown below.
  • Page 30: Displaying Surface Fish Clearly

    2. FINE TUNING THE SONAR PICTURE 8. On a long range, locate a fish school which is approaching own ship. Note that the tilt should be kept adjusted so that the fish school is always placed in the center of the sonar beam, i.e., so that the fish school is displayed in strongest colors possible.
  • Page 31: Pulse Length

    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 32: Suppressing Bottom And Sea Surface Reflections In Shallow Fishing Grounds

    2. FINE TUNING THE SONAR PICTURE Suppressing Bottom and Sea Surface Reflections 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 aforementioned TVG and AGC, especially when the tilt angle is large in order to track fish schools approaching within 400 m.
  • Page 33: Rejecting Sonar Interference And Noise

    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 35: Choosing Beamwidth

    Choosing Beamwidth 2.6.1 Horizontal beamwidth If you wish to have better bearing discrimination (ability to distinguish two closely located targets at the same range and different bearings) for fish schools and also wish to examine the contour of bottom, set HOR BEAMWIDTH to NARROW, on the SONAR menu.

  • Page 37: Advanced Sonar Operation

    ADVANCED SONAR OPERATION Tracking a Fish School (target lock) Target lock, which requires speed and heading inputs, automatically tracks a fixed location (such as a reef) so that you won’t lose sight of it on the display screen. 1. On the sonar display, operate the trackball to place the trackball mark on the location you want to track.
  • Page 38 3. ADVANCED SONAR OPERATION Note 3: The target lock feature tracks a target up to 55° tilt angle. For example, if a ship moves from position A to position D, the target lock works between positions A and B. The tilt angle is fixed between positions B and C is 55°, however calculation continues internally.
  • Page 39: 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 bottom through the built-in speaker.
  • Page 40: The Fish Alarm

    3. ADVANCED SONAR OPERATION The Fish Alarm The fish alarm generates an audio alarm when a fish echo above a certain strength enters the alarm zone. 1. Operate the trackball to place the trackball mark on the starting point of the alarm zone.
  • Page 41: Measuring Fish School Speed

    Measuring Fish School Speed 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.

    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 horizontal 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 anchoring chain that extends from surface to bottom.

    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 65: Sea Surface Reflections

    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 66: 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 water with a hard and rocky bottom, strong target signals are detected by the sidelobe.
