We know that buyers can get confused when it comes to purchasing fishfinders. That’s why we’ve invested a lot of time in completing a thorough research. We would like to give a helping hand to all users out there who are a little puzzled as to which features are a must and which they can do without.

Since the price of some models can be as high as $1,000 or even more, it is very important to read as many fish finder reviews as possible. Other buyers’ opinions are often unbiased and will tell you exactly what you need to know about one unit or another.

Additionally, we’ve selected a number of models that we think are the best. Do not feel compelled to take our word for it, as we’re only here to help. All of the following information has been collected in countless hours of researching the market, so if you think buying the right fishfinder is a daunting task, just have a look at the buying guide.

What do fishfinders actually do?

Because the only thing that fishfinders aren’t truly capable of doing is catching fish for you, they are sometimes unfairly denigrated. Despite the fact that they are extremely complicated electrical devices, it is crucial to understand that they are primarily composed of two very important components: an LCD display screen and a transducer.

For those who are interested in knowing how they function, the simplest explanation is that all of the information that you see is produced utilizing sonar technology. The device emits a sound wave that penetrates the water and generates a cone-shaped beam of light at the surface.

Product descriptions frequently do not include information about the cone angle, which is determined by the manufacturer for each particular model.

While some fishfinders are equipped with a single beam of sonar, others, such as those manufactured by Humminbird, are equipped with multi-beam technology. This last feature allows the unit to send out between 2 and 6 sonar beams, which do an excellent job of covering a bigger area as compared to units that only have a single beam, which are more expensive.

Angles between cones can range from 20 degrees to 110 degrees. What does this mean for you and your family? The gadget can scan up to 13% of 10-ft water depth with an angle measurement of 20 degrees, which is sufficient if you want to fish in shallow water. Fishfinders with a scanning angle of 110 degrees, on the other hand, are more than capable of scanning up to 2.85 times the depth of the same 10-foot water.

The selection of a certain model is a subjective matter because the performance of the device is often dependent on the type of transducer that is used, as well as on elements that are outside the control of the user, such as the temperature and purity of the water.

Choosing the Right Fish Finder

Here’s what you need to look for if you want to get the right unit for your own needs.

Screen info

When it comes to buying fishfinders, screen size matters a lot. Ancient models come with sizes of screens that resemble the one in old cell phones. They’ll do a good job at detecting fish, but you’ll have trouble actually seeing it. Cheap basic fishfinders come with grayscale screens, and this is another reason why you might have a hard time visualizing your catch.

We recommend considering a color model that features downscan/down imaging, as this function is responsible for creating picture-like images.

Resolution is yet another detail to reflect upon. In this case, the rule is simple: the more pixels, the more detail.


Transducers come in a variety of shapes and sizes, but to pick the right model you need to know the material your hull is made of. For instance, transducers made of plastic work great for fiberglass or metal hulls, while the bronze ones are perfect for wood hulls. Some produce a narrow beam that will work for deep waters, while others capture wider displays that are fit for fishing in shallow waters.

Power and frequency

Because the issues of power and frequency are so closely intertwined, we’ve decided to handle them all at once. Higher wattage is advised for persons who want to be able to see clear images that are produced swiftly and efficiently while also maintaining comfort. A decreased power consumption will result in a slower reading speed and blurry visuals.

When it comes to frequency, the higher the value, the more detail you’ll be able to see displayed on the screen. Example: A 50 KHz frequency at 100 Watts will provide depth measurements of up to 400 ft, while a 200 KHz frequency at the same power will provide depth measurements of up to 100 ft.

All things considered, fishing in shallow waters does not necessitate the use of much force, whereas fishing in deep waters necessitates the use of a lot of power. As a result, the 50 KHz frequency that we were talking about will be ideal for deep water operations. Our recommendation is to get a model that allows you to customize the frequency of the alarm, especially if you plan on going on an ocean fishing adventure.

GPS capability

This feature is a must for people who tend to fish far away from home. If you live in an area that’s constantly affected by hurricanes and other hazardous natural phenomena, the GPS or a cartography system will bring you back home safely. Weather info is a plus.
