Fish Finder User Manual

Fish finder is a gadget to locate the position of the fish or the density of the fish under the water t make an economical and exciting fishing trip. Previously a fish finder was used by the professional fisher man who used to go for fishing in the ocean for a couple of days or weeks. That time, the machine provided a great service to them by making the trip economical and profitable. But nowadays, occasional fisherman, who goes for fishing in the weekend to leave the busy and monotonous city life for a while, also uses the fish finder in their occasional fishing trip to make that trip more exciting.


Whether you are a professional fisherman or occasional fisherman, you have to know the proper use of a best fish finder to get the highest possible output from the machine in this site. Most of the people will be aware of the basic of the fish finder by using it for one or two days. But the feature does not end in the basics. The machine will offer you plenty of opportunity to know about the underwater atmosphere if and only if you can possess the right knowledge about the machine. Are you interested to learn a bit more than basic of a fish finder? Great! Today I will give you the idea of some advance option of a fish finder. No worry if you are a beginner, the basic will be discussed too. Along with that, I will give you idea about some basic fish finders. So, let’s begin:

Synchronization or Co-ordination:

The basic of a fish finder is pretty clear. The transducer transmits ultra sonic sound frequency to the sea bed and surrounding. If the sound wave gets any obstacle, a portion of it reflects to the receiver. The transformer transforms that sound energy to electric energy and the amplifier amplifies it to some extent. Then the processor calculates it and show on the display.

The first thing you have to do is to co-ordinate your chart with the fish finder machine. It will increase your capability to locate the fish very much. As you know, the gadget will show you the fish position with light blink, spot and bobs. But if you set up the display in a long range or a small scale chart, surely you will miss them after a while. Many people have different ways to co-ordinate the chart with the machine. But the best way is to make the division in your charts and set the gadget accordingly. You can use the large scale chart to apply the appropriate position.  If you do not have this mixed equipment, you are recommended to upgrade the system.

Zoom Operation:

I think, within this time, you are already capable of combining the search engine with drawing system. Zoom tool is also a good option for you and your operation. By this mood, you can avail a lot of information about the fishing ground you are floating on. Not only the information about the area, you can also get an idea of the size and shape of the fish at the bottom.

You have to be aware of the display presentation in this mood. Most of the machine has the same kind of display module. In some case, a soft bottom in will slowly represents a hard bottom line and vice versa happens in different case. It actually depends on the frequency of the ultrasonic sound that is transmitted from the transducers and the time difference between the transmitting and receiving. There is a catch in this mood. You need to gain some experience to operate the machine in this mood. The greatest benefit of this zoom mood is you can put attention to a particular water level and scan that range (for example 5 meters to 10 meters) for your desired fish species.

Sensitivity Tuning and Adjusting:

Nowadays, the modern fish finders have built in high processor which is capable of adjusting and tuning its sensors and wave frequencies according to the atmosphere to achieve the best result. You can easily depend on this modern technology. But the technology has some limitation than ur brain. This processor can tune the machine in normal atmosphere but it gets confused in some situation like turbid water, water having a thick amount of phytoplankton or fungi on it. In such situation, you have to step forward and tune the sensors accordingly as the processor is already confused about its activity and atmosphere.

In such condition, a lot of clutter is visible on the display due to this disturbance. You should peak your transducer, reduce the present sensitivity until all the clutter eradicates from the display.

I hope you already got the basic idea as well as operational knowledge about the fish finder. Try to move in every possible option you can operate to know the machine well. The more you are familiar with the gadget, the more accurate result you can obtain from it.
