How to choose Best Fish Finder

Fish finders are not just any sonar-equipped boxes and have a lot to them. The design, development, and production of these instruments require a lot of effort and research. A lot of fishermen do not take all this into account before buying a fish finder. However, a professional fish finder will definitely consider the various features that are listed below.

Display Screen

Display screen must be considered before buying any fish finder. Greater screen sizes are preferred as they help you to find the exact spot of the fish. Full-color screened fish finders are preferable than the black and white ones as they give clearer details. A higher resolution must be selected as it avoids a number of blurry dots on the screen and gets a clearer picture of the fishes below the water. The minimum resolution recommended is 240X160.


Transducers are responsible for the transmission of sonar signals. They receive and send signals. You must select a fish finder that has a good quality transducer and can send and receive signals from greater depths.The transducer must be properly configured and send signals deep into the waters. The frequency of the transducer must also be kept in mind. For fishes at different depths, the transducers would need to have different frequency levels. Some of the best fish finders use multiple frequencies to operate and are in demand for this reason. The portability of the transducers is also an important factor to consider when you want to buy a fish finder. By mounting a fish finder, you could be interfering with its frequency.

Power of the best fish finder

The power of the fish finders is measured in terms of wattage. The higher the power, the faster is the operation of the sonar. The greater power of fish finders indicates the capability to give faster live results. Fish finders of the higher power can give more accurate results and so should be considered while making a buying decision for fish finders. Cone Angle By the cone angle, one gets an idea of the width of the “net” the signal will cast after it has left the boat’s bottom. The more the depth of the water, the wider will be the cone. However, there can be a dip in the sensitivity. The usual range of the cone angles is around 15-20 degrees. But, there are some cones that can cover around 9 degrees while some others that can go up to as wide as 60 degrees. Professional fishermen prefer to use fish finders that have more than one cones so that it is possible for them to capture different angles and also overlap in some specific spots.


There are two ways in which best fish finder can scan

Side scan or Side imaging

Side scan fish finders allow scanning great amounts of water, but are not very effective in greater depths.

Down scan or Down imaging

The down scan fish finders are more focused and powerful. But, by using them you could miss out on fishes that are exactly underneath your boat.

Multiple fish finder

Recently, fish finders with dual-scan features have also been innovated and are slowly being put to use. It is still a long way to go till we find them available for regular commercial use. Until then, the best option is to use multiple fish finders.


Portable fish finders became increasingly popular in the recent times and have been preferred over other fixed models in many situations. Portable devices are convenient for use when you are fishing from a small boat or a kayak. By casting the transducer into the water, you can get your information about the fishes. Such fish finders are often used while fishing in ponds and lakes and other small water bodies. While fishing in an open ocean, it is still advisable to select the traditional varieties of fish finders.

Final Verdict

We have sifted the best fish finders out from a wide range of fish finders in the market. For you to buy one, see which one suits your needs.
