But if this is a whole new thing to you, you don’t have to worry since we are here to help you find the best fish finder on the market.

To buy the best fish finder, you will need to know what to look for when choosing one, the price range and the some of the top products with proven success rates. The good thing is that you will not have to look further for this information since that is precisely what you will find in this article.

Things to consider when buying the best fish finder

You want to use the right fish finder on your fishing trip to make it enjoyable and less frustrating, and the best way to do this is knowing what you should look for in a fish finder when you go shopping. The main ones are:


The wattage of the fish finder is an essential factor to consider since it contributes to the efficiency and convenience of using the device. You want a fish finder that will display results fast enough and serve you for as long as you will be on the fishing trip, and that will require the highest wattage possible. All finders will have an indication of the level of wattage from 100-1000W.

Among the things that should dictate the amount of power to use is the depth of the water in which you will be fishing. Fish finders use sonar waves to locate fish, meaning that the shallower the water, the less power you will need. On the other hand, when fishing in deep water bodies, a powerful finder will be ideal since the readings will be displayed fast and will be clear.


The frequency of your device will affect the amount of detail showing up your screen. The higher frequencies – 192 and 200 kHz – are ideal for use in the shallow waters and the low kHz transducers are best for use in deep waters. The frequency of the fish finder will relate to the cone angle and will be 50, 83, 192, 200 or 400+ kHz for dual, single and multiple frequencies.

Therefore, you need to know where you will be fishing to know the right frequency range to pack.


Most fish finders are not bulky or heavy, but depending the type of fishing and the way you will be fishing, knowing the size that works for you will come in handy. For instance, most off-shore fishing requires that you use space efficiently and the best portable fish finder would be ideal.

Screen color

While this goes without saying, it is still worth noting that color screen fish finder is the best pick for your fishing trip. They offer great detail beside being stylish and clearer than the black and white screens. As such, you will be able to see what if going on and to differentiate fish from underwater objects that may pop up on the screen.

Another good thing about the color screens is that you can use them any time of the day regardless of the brightness. This is not always possible with black and white screens especially when the day is too bright. However, if it is the only your budget can allow you to get at that time, half a loaf is better than none, don’t you agree?

Screen Resolution

The other thing to consider is the fish finder’s screen resolution which will be described in terms of pixels. To put it into context, think of a single pixel as a dot on your screen. Best-fish-finder-reviews Therefore, the more pixels you have, the more detail and clarity you will have on your screen. The minimum pixels which will make your screen look okay but not as clear as it should be is 240 x 160 Pixels.

For crispier and sharper images, go for a fish finder with the highest resolution, and when combined with the right size of the screen, you will be sure to have a great time fishing. The small screen units are ideal choices for secondary or backup fish finders. If it is the main unit, go as big as your pocket will allow.


When buying a fish finder, pick one whose transducer’s installation does not require a lot of skill. Transducers are a component of fish finders whose work is to emit sonar signals to the water and receive them after bouncing off objects. This information is sent to the main unit and displayed on the screen as a picture.

In most instances, the transducer is mounted on the boat, and the one that will work for you depend on a number of factors including your needs and the water in which you are fishing.

Cone Angle

The cone angle of a fish finder can be described as the width of the beam sent into the water from the unit. In essence, it is how wide of an area the fish finder will cover when in use. It follows directly that the wider the cone angle, the larger the area covered by the fish finder, but with the increase in the depth of water, the sensitivity drops.

Cones range from 9 – 60+ degrees with the standard range being between 16 and 20 degrees. The good thing about transducers is that they can have multiple beam-emitting cones for more advanced needs. For this reason, you will be able to cover a large area which is ideal if you are fishing in a large water body.

Other considerations

Additional features to look for in the best fish finder include the wireless feature, water resistance, GPS and mapping and the material used to make the transducer. These options will majorly depend on your preferences and the amount of money that you are willing to spend.

How We Picked the Best Fish Finders?

The fact that there are many things to consider when choosing a fish finder makes it difficult for many fishers to pick the right unit. That is why we took the time to research and consider all the relevant features required in a fish finder and came up with the list of top products.

Another criterion was to go for the best rated fish finder on the market. These are those that many fishers have tried and tested and found to be working according to expectation. The resulting list is comprehensive and includes the fish finders that you can count on to have the best fishing experience.

How much does a good fish finder cost?

One of the questions many fishers want an answer to, before setting to buy a fish finder is the much it will cost them. Well, the truth is that you will more likely find a wide range of fish finders with different prices. The market has fish finders from as low as less than $100 to more than $1000.

There is no doubt the cost of a unit will depend on o the features it comes with. For instance, a color screen fish finder will more likely cost more than one with a black and white screen.
