47 17. THEORY OF FISHFINDER 1. THEORY OF FISHFINDER Theory of fishfinder is same as echo among hills Ultrasonic wave transmitted from the transducer directly beneath the vessel is reflected at the sea bottom and received by transducer. Fishfinder indicates the depth by calculating the round-trip time to distance. Also, the unit shows the color image of fish school size/density or sea floor condition according to the strength of reflected wave. Ultrasonic wave runs at 1500m/sec inside the water. Therefore, the depth to fish school and sea bottom can be captured by calculating the round-trip time. Round-trip time 1sec Round-trip time 0.5sec Transducer Reflection from fish school Reflection from sea bottom e.g.) 1sec is round-trip time from sea bottom. Round-trip distance=1500m/sec 1sec =1500m The depth is half the size, so Depth=1500m =750m 0.5sec is round-trip time from fish school Round-trip distance=1500m/sec 0.5sec =750m The depth is half the size, so Depth=750m =375m Display Method Current image is shown at 1 st line of right edge after processing the reflected wave of transmitted ultrasonic. The line image previously located at the right edge moves to one line to the left. Keep executing this operation to create the cross section view. Therefore, the latest image beneath the vessel is located at the right edge. More left side the image moves, more past image the screen shows. You can assume that fishfinder screen shows the image from the side view. The sea floor shape can be only captured when sailing the vessel. No matter how the bottom is shaped, the image shows the flat bottom if the vessel is stopped. Current image Past image There is no relationship between vessel speed and image line speed. 43

48 . Distinguish of Fish School Important tip is comparison between fish school image and actual catch Possible to judge the fish type to some extent from the image of fish school. The shape of fish school changes even for same fish group by time(day/night, season, current change). The important tip to distinguish the fish type is to know fishing point and fish type according to fishing season. Then, compare the fish image and actual catch and look for the point. 3. Distinguish of Fish Quantity Distinguish fish quantity from density/size of fish school. Higher density of fish school has stronger reflected wave. Therefore, the fish density can be seen from the color strength of image. It is wrong that fish quantity is larger for large image on the screen. Fish school located deeper area tends to appear bigger compared to the one at shallow water. This is because the width of transmitted wave becomes wider as it go deeper. The reflected ultrasonic wave becomes bigger as the distance (depth) gets further. The important tip to distinguish the fish quantity is to know fish school located at deeper water appears bigger. Judge from size of fish school and color strength. Reflected ultrasonic Fish school A Fish schoola Image(Shallow) Fish school B Fish schoolb Image(Deep) 4. Distinguish of Sea Floor Condition There are many types of sea floor conditions such as rocky, sandy, or muddy. The condition can be judged by the upper/lower width of sea floor image and nd echo. The reflection is stronger for hard bottom such as rocky area. The image width is thicker, and nd echo tends to appear. On the other hand, the reflection is weaker for soft bottom such as sandy and muddy area. The image width is thinner, and it s harder to have nd echo. nd echo Ultrasonic wave initially transmitted from transducer, reflected from the sea bottom, reflected back at water surface, and reflected again at sea bottom. In short, it is the image (ultrasonic wave) which made -times round-trip. Rocky area Sandy or Muddy area nd echo 44

49 18. CAUTION ON SAFETY When the unit has any problems, please check the following points before sending back the unit for repair. Symptoms Cause Remedy Power cannot be turned on. No display on screen Bottom or fish cannot be displayed at all. Image does not appear sometimes. Voltage of battery is lower than standard value (11V). Contact of power connector is poor. Wrong connection of power. Opposite polarity +-. Cut wire inside power cable. Blown fuse. Brightness is set to minimum level. Contact problem with transducer connector 45 Recharge the battery. Retighten it. Remove and clean the rust/dust. Replace it in the case of corrosion. Replace the power cable Replace the connector on the unit. Check the polarity and connect it property. Exchange to new power cable. Send it for repair. Adjust the brightness. (refer to [Brightness Adjustment] p.19) Retighten the connection. Remove/clean the rust/dust. Replace it in the case of corrosion. Send it for repair. <Problem with Transducer> Check followings and replace it in the case of actual problems. 1.It s normal if you hear the sound like Bo Bo from the surface of transducer..it s normal if rain like dots appear on the transducer surface after setting the sensitivity and depth to the max and rubbing the transducer surface. Transducer is not immersed enough into the water. Internal liquid is not enough inside the case. Transducer is not immersed enough into the water. Problem with transducer installation causes the image problem due to air bubbles at speeding the vessel. Influence from other vessel causing air bubbles. Adjust the transducer installation so that it is always beneath water surface. Add enough liquid to immerse the transducer. Adjust the transducer installation so that it is always beneath water surface. Check the installation of transducer. Move to other location or wait until air bubble disappears.

50 Symptoms Cause Remedy Bottom or fish school is not displayed well. Too low sensitivity. Rubbish and weed attached on the transducer surface. Dirty bottom or liquid. Increase the sensitivity. Or, set to auto gain (auto sensitivity control). Remove the excrescence. Remove the dirt from bottom and exchange the liquid. Water and environmental conditions may cause the problem with image which is not problem at all. Too much noise Too much sludge Too high clutter. Too high sensitivity Lots of weeds Interference with other vessel s fishfinder Noise from engine Muddy and Rapid current dirty locations Activate low reflection color. (refer to [CLUTTER] p.0.) Lower the sensitivity. Set to auto gain (auto sensitivity control) Noise disappears after other vessel moves far away. Change the routing of cables such as transducer and power cables. (keep distance from the engine as far as possible) 46
