Quick Comparison – Best Fish Finder for Small Boats
Searching for the right fishfinder for your boat can be overwhelming as you have so many options available on the market. We have provided you with the best options suitable for you so that it easy for you to select the right one according to your needs.
To further narrow down your search we will acquaint you with the important features to look out for in a Fishfinder before investing your hard-earned money. Let’s look at each of the features in detail:
If you are going to use an in-hull or a thru-hull transducer mount then you need to be careful about the material that the Fishfinder is made of. Whichever material you opt for should be compatible with the hull of the boat. So, if you have a wooden hull it is good to opt for bronze housing material.
On the other hand, if the boat has a steel or aluminum hull then you should go for stainless steel housing material as it is more durable and compatible. If you are an amateur then plastic housing would also be a good fit.
The choice of the battery would depend on your usage. So, if you go fishing for a couple of hours then you can opt for finders that have AA or AAA batteries but don’t forget to carry extra ones in case they run out.
On the other hand, if you like to spend the whole day fishing then you should go for finders with rechargeable batteries that have a longer battery life and you can also pack some spare batteries just in case you run out.
Frequencies and Cone Angles
Another important consideration before getting a fish finder is its frequency. The finders are available in single, dual as well as multiple frequencies. The frequency of a model would depend upon the cone angle. The distance and speed of travel of the cone beam is directly related to the cone angle.
So, if you go for a high frequency mode then it will provide you more detail as compared to a low-frequency Fishfinder. Higher frequencies are suitable when you are fishing in shallow waters.
If you are fishing in deep waters then a low-frequency transducer will be a good fit for you. Also, people who regularly go for fishing at one spot can opt for a low-frequency Fishfinder as a single frequency will work well for them.
Also, some fishers come with both large and small cone areas and this helps you choose the cone area according to the depth you are fishing at. These days many finders come with a lot of customization so you can choose the right frequency and cone angle according to your needs.
Although these are generally costly but you can use them for different fishing styles and depths so they are worth the investment.
Display resolution of the screen is important in order to view the images and other info clearly. If you want sharp pictures then go for maximum pixels. However, you will see that some displays work fine with fewer pixels and might be good enough.
The minimum resolution that is required to see images clearly is 240×160. A basic Fishfinder would generally have less resolution and you will not be able to see many details in this resolution.

Best Fish Finder for Small Boats – Frequently Asked Questions (FAQ)
As you go deeper you would need lower frequency as they travel larger distances and provide better returns. So, your fishing depths and frequencies are inversely correlated. If you are fishing in depths that are more than 1,500 feet then you should opt for frequencies lower than 140kHz.
On the other hand, if you are fishing in medium water depths that range from 600 to 1,500 feet then it is good to go for frequencies between 80kHz and 150 kHz.
If you are fishing in shallow waters up to 600 feet then opt for frequencies above 150 kHz to get an optimal performance.
Yes, seasoned fishers may be able to determine the species of fish based on their sonar returns, however it takes a lot of skill and practice.
The fish are detected with the help of their air bladder which varies from one species to another. As all the fish belonging to the same species have the similar shape of returns it is possible to identify the species.
As a matter of fact, all three of them do! But if you are looking specifically for ice fishing, you might also want to check out our article on the best ice fishing flashers.
