Lessons in Reading a Fish Finder Transducer

Among all the devices that were invented for the fisherman, the fish finder might just be the most incredible. However, it may be difficult to learn at first but once you get the hang of it, you can do it with your eyes closed.

When using a fish finder, you should remember that the SONAR is reflected on the screen of the fish finder in a right to left direction. This means that the latest reading is the one which is being shown on the right. This kind of direction may not be a problem if the boat you are on is moving. The SONAR which is reflected on the right most is the area which your boat just passed. However, it becomes tricky when the boat is not moving. When the boat is still, this is not considered

This is a HummungbirdPiranhaMax 190c. This one has the most basic of features and displays its readings on a 3.5 inch colored screen. It is classified as an entry-level fish finder.

As you may have noticed, the image reflects two number on the top left of it screen. These two readings indicate the depth of the reading and the temperature of the water. The temperature only shows up on the screen if it has a sensor which reads the temperature. It is also possible to read how fast the boat is going. However, it is not available in all the models.

Take a look at the thick red wavy line that the monitor of the image above is showing. This line indicates the bed of the body of water where you are at. If you may have noticed, when a thick red wavy line has green beneath it, it signifies that this portion has a soft bottom. This kind of reading is caused by SONAR waves bouncing back from the bottom after penetrating the bed deeply. If it is a soft bottom, it causes the waves to bounce back slowly. If the monitor only shows a thick red wavy line, then this indicates that the bed beneath your boat is

This indicates a structure on the bottom and it should be noted that fish loves to hang out in certain structures. So, this is the best place to look for your catch. If you see arches above the structure, then that is a definite indication that you have hit the jackpot.

High Frequency Down or Side Imaging Finders

This model that you are seeing above is an image of a Hummingbird 398ci Side imaging fish finder. The sides images are made possible by the side imaging transom mount transducer. This is specially made for this model. In addition, it can also read the depth of the water which is indicated at the top left corner of its screen. It is also able to read the water’s temperature and its speed.

If you noticed, the images that it reflects are clearer compared to the previous model. This is because it uses a higher frequency. The resulting image is the same as when you stick your head into the water, or taking a look at your self at its
