What is A Fish Finder?

Fish Finder is one type of device which will allow you to locate fish underwater via detecting the pulses of sound energy which is in sonar. You will be shown a graphical data of whether there are fishes underwater or not. Some of these fish finders will also show you sand, small or tall weed. Some of the best fish finders have other different types of features like GPS, multimedia support, advanced navigational system. Some advanced powerful fish finders even have down imaging system that will provide you with a high-quality picture like image of the bottom and structure. However, these devices can measure the depth of water also. One of the most important things about these devices is that these best fish finders will surely maximize your fishing experience.

How to Choose the best fish finder?

Fish finders have many several functions with add-on features. The main purpose of a fish finder is to find the fishing spot. However, it also depends on the beam, transducer, and other features. We will provide a short review on what can make these into the list of best fish finders.


The transducer is one of the most important parts of your fish finder. It is connected with the fish finder device, and it throws a “ping” into the water and listens to the echo. It is a must to have a good transducer system for your fish finder because without a right transducer your fish finder will perform very poorly. Transducers send sonar signal to the water which gets bounced back from the objects underwater & gets picked by the sensor. The outcome is an image which might differ from fish finder to fish finder, but the general reading is quite same. If you are using an advanced fish finder, you might get an image like picture on the screen.

Usually, most fish finders come with a transom mount transducers out of the box. These are pretty easy to install with less effort. However, if you are looking for a more advanced purpose, you may want to go for other transducers like hull through.

To choose the best fish finder, you need to check with the transducer features too. One of the essential features of the transducer is the cone angle. We have written about the cone angle below.

Cone Angle 

Cone angle is significant features to choose the good fish finder for yourself. Assume the cone angle as a point from the beginning of the transducer. It starts spreading from the point and the deeper it goes, it becomes wider. Please note that the more it widens and goes underwater, the more it loses its sensitivity. Usually, the cones range from 9 degrees to 60 degrees. Normally the transducers come with a cone angle of 16 to 20 degrees. Most of the time, 20-degree cone angle is good for most anglers.


Most of the transducers have a single beam. More advanced transducers come with dual beam, triple beam, side beam and more. These superior beams offer you the service to cover more water beneath your boat. This option comes very handily when you are looking for fishes in a big lake or river. If you are looking for the best fish finder, try to get a fish finder with at-least dual beam.


A good angler will always choose the best fish finder with proper frequency. It is related to the angle of the cone. Usually, fish finders come with a 50,83,192, or 200 kHz frequencies.

For shallow water use 192 & 200 kHz.
For deep water use 50 kHz.

If you are going for fishing in shallow water, it is advised to choose a fish finder with high frequency as it will allow you high-resolution display. If you are going for saltwater then selecting a low frequency will be better.

how to choose frequency for fish finder

Please note that high frequencies show great detail of the bottom, but a lower frequency comes best at the deep water which will display a wide area of the bottom. Most of the fish finders come with dual or multiple frequency transducers like 50/200 kHz.


Power is another factor that you need to check while getting a fish finder. The power of fish finder is measured with wattage (w). Usually, if the wattage is higher, your device will show faster and accurate readings. However, if the wattage is low, then it will take more time to show the data.

However, if you are looking for fish in shallow water, then low wattage will do the work for you. But if you are going to fish in big lakes then you need a more powerful unit. Usually, 600 watts is enough for shallow water and for serious anglers it is recommended to use a fish finder with 1000 wattage or more.


The display is another important factor while choosing the best fish finder. If your fish finder has a big screen, it can offer more data easily. Advanced fish finders come with color display along with other features. Advanced fish finders with big color display come with high resolution and great image like pictures of the objects below your boat.


Most of the advanced fish finders come with a GPS option. It is basically included in the device which will help you to find the spot you previously found. This will even help you to navigate through the lakes, rivers or in the ocean. This actually helps to minimize your effort to find the best fishing spot you found previously.
