  • Page 16: Adjusting Gain

    1. OPERATIONAL OVERVIEW Adjusting Gain Most equipment malfunctioning claims result from improper setting of switches and controls. For example, fish, fish habitat or outcrop can not be readily detected by merely increasing the gain. Initially set the gain between 3 and 5 with the GAIN control. Then, fine tune depending on the fishing ground, frequency used, etc.

  • Page 20: Setting The Tilt Angle

    2. SONAR MODE Setting the Tilt Angle The tilt angle shows the direction to which the sound wave is emitted. When the sound wave is emitted horizontally, the tilt angle is said to be 0° and when emitted vertically, 90°. To set a tilt angle, operate the TILT control. Watch the tilt angle indication at the top right corner of the screen.

With navigation data input, the event marker moves with ship’s movement.

  • Page 23: Detecting Schools Of Fish Effectively

    2. SONAR MODE Detecting Schools of Fish Effectively 2.7.1 Relocating a school of fish for easy observation When a school of fish is near the edge of the screen and inconvenient for observation, use the expanded sonar mode and adjust the TRAIN control (off-center function) to relocate the school of fish close to the screen center.

  • Page 24: Detecting Schools Of Fish Aurally

    2. SONAR MODE nearly equal. The sonar operator will be quite inconvenienced if these echoes are di- rectly displayed on the screen, since he won’t be able to judge the actual size of the target from the size of echoes displayed on the screen. To overcome this inconve- nience, use the TVG function.

  • Page 25: Rejecting Sonar Interference And Noise

    2. SONAR MODE Rejecting Sonar Interference and Noise While observing the sonar picture, you may encounter occasional or intermittent noise and interference as shown below. These are mostly caused by onboard electronic equipment, engine, propeller noise, or electrical noise from other sonars being oper- ated nearby.

    2. SONAR MODE Interpreting the Display 2.9.1 How the picture is painted The wide sounding beam is emitted from the soundome at a certain tilt angle (see hatched area in the figure below). The information (target echoes) obtained by this beam is displayed in 45°...

  • Page 27: Schools Of Fish Echo

    2. SONAR MODE 2.9.3 Schools of fish echo A school of fish appears as a mass of echoes on the screen. The color of the mass shows the density of schools of fish on the sonar beam. To find distribution and center point of a school of fish, try several different tilt angles.

  • Page 28: Wake

    2. SONAR MODE 2.9.5 Wake A wake produced by own ship or another ship can be a strong reflecting object when a narrow tilt angle is used. As the wake appears as a thick continuous line, it can be easily distinguished from a school of fish. A wake contains many air bubbles which at- tenuate ultrasonic energy, making it difficult to sound beyond the wake.

    3. VERTICAL FAN MODE 3.10 Applying Proper TVG The TVG function is the same as the one explained in the sonar mode. For best re- sults, set both TVG level and time a little lower than the ones in the sonar mode. The setting is mode on the BOTTOM/3D menu screen and the usual setting for both time and level is 3.

  • Page 36: Net Mouth Marker

    3. VERTICAL FAN MODE 3.12 Net Mouth Marker The net mouth marker is a tool use to help determine the best timing to raise the nets. This can be achieved by displaying the net mouth marker with the fish echoes. The net mouth marker is displayed as shown below.

VERTICAL FAN MODE 3.13 Interpreting the Display 3.13.1 How the picture is painted The sounding beam is emitted and the information (target echoes) obtained by the beam appears in the corresponding sector as it appears on the sonar mode. The dif- ference is that the training is performed only in vertical direction.
