    1.6.2 Sample display mode pictures Below are typical pictures. For sake of brevity indications and marks are not shown. Horizontal mode This mode provides 360 degree coverage around the vessel and it is useful for general search. For further details see Chapter 2. 2000 Figure 1-8 Horizontal mode display 1.
  • Page 22 1. OPERATIONAL OVERVIEW V1 and V2 modes The V1 and V2 modes show a vertical slice of the bearing selected by the vertical bearing mark on the horizontal display. The vertical 2 mode provides two vertical slices. Chapter 3 discusses the vertical mode. V1 + ES1 (or ES2) mode The V1 + ES1 (or ES2) combines the vertical 1 display with the picture from an echo sounder or a net recorder.
  • Page 23 History mode The history mode shows the horizontal and history displays. Echo data for the echoes within the history marker on the horizontal display scroll down the history display in the downward direction – the latest echoes at the top and the oldest at the bottom.

The net recorder display can show the downward looking picture alone or both the downward and upward looking pictures. Note that this mode can also show the echo sounder picture. Figure 1-13 ES2 display (shown: downward picture) ES1 + ES2 mode The ES1 + ES2 mode shows the echo sounder and net recorder displays.
  • Page 25: Adjusting The Gain

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

  • Page 32: Automatic Tilt

    2. HORIZONTAL MODE 2.4.2 Automatic tilt The [AUTO TILT] key automatically scans the tilt angle within the selected width. This is useful when you want to find the center depth of a fish school. 1. Press the [AUTO TILT] key to select auto tilt angle desired. Each time the [AUTO TILT] key is pressed the auto tilt angle changes in the following sequence.
  • Page 33: Bottom Echo And Tilt Angle

    For example, when the [RANGE] control, [TILT] control and [AUTO TILT] key are set to 200 m, 8 and width (1) respectively, the tilt angle changes at each transmission as follows: Note: The [AUTO TILT] key is inoperative when the target lock function is active or is made active.
  • Page 34: Tilt Angle For Surface Fish

    Fish school "a" Points to consider Normally, a vertically distributed fish school is a better sonar target than the bottom, because it reflects the transmitted pulse back toward the transducer. In case 3, both fish schools “a” and “b” are presented. Generally speaking, however, midwater fish schools tend to be larger than bottom fish schools and they are often displayed near the bottom on the display.

  • Page 38: Suppressing Bottom Tail

    When fish school is located on a long range setting (about 800 meters) and is approaching own ship do as follows: Adjust the tilt to keep the fish school in the center of the sonar beam, namely, fish school is displayed in strongest colors possible. Confirm that the fish echo is displayed in the same color as it approaches.
  • Page 39: Agc

    While it is ideal to suppress bottom echoes with the AGC alone there are some fishing grounds where this is not possible. (The high power sonar has the advantage of long-range detection but this can also be a disadvantage, since weaker echoes may be hidden in strong, unwanted echoes such as the bottom.)
  • Page 40: Suppressing Bottom And Sea Surface Reflections In Shallow

    2. HORIZONTAL MODE Suppressing Bottom and Sea Surface Reflections in Shallow 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 functions, especially when the TILT is set to a larger angle in order to track fish schools approaching within 400 m.
  • Page 41: Rejecting Sonar Interference And Noise

    1. Stop transmission on the TEST menu, referring to page 7-10, and turn on the power of all on-board equipment one by one while observing the picture. If noise appears on the sonar display, that equipment is emitting noise. Check the offending equipment’s ground and installation.
  • Page 42: Changing Tx Interval

    6. Select QUIT at the top of the menu screen and press the [MENU] key to close all menus. Note: When the sonar is used in shallow water with the range set between 60 m and 200 m and Tx cycle at “9”, bottom reflections caused by the 2nd-to-the-last transmission may appear on near ranges.
  • Page 43: Noise Limiter

    2.9.5 Noise limiter Weak, unwanted reflections, colored light-blue or green, appear when the water is dirty, plankton layers exists, or due to ship’s noise. The noise limiter can reduce the effects of these unwanted reflections. Raising the setting causes unwanted reflections to become colors of blue to background color. Normally a setting of 3 or 4 is sufficient.
  • Page 44: Tracking A Fish School (Target Lock)

    Two types of target lock are available: position (TARGET MARK) and fish school (FISH) and you may select one from the menu as below. Default setting is “FISH.” However, if the FSV-24 can not receive sufficient level of echo, tracking may not be performed.
  • Page 45: Fish School Mode

    If the target is lost, the tracking mode changes to position mode (see next section) at that position. When the FSV-24 detects and tracks the target again, the mode returns to the fish school mode. 4. To turn off the target lock, press the [TARGET LOCK] key again.

    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.

    Tracking of bonito and tuna presents a special challenge to the sonar operator: He must try to keep them within the sonar beam, a formidable task considering their high speed and penchant for leaping and diving. The FSV-24, however, with its vertical beam, makes this task easier.
  • Page 88: Approaching

    While a flock of birds hovering over the sea surface is usually a good indication of the presence of a fish school, the sonar can better verify fish school size. 3.13.4 Catching While the sonar operator monitors the sonar for other fish schools, the crew can scatter bait and water to attract fish to the boat.
