Best Fish Finder for Small Boats Buying Guide

Here are a few important things that you need to know to maximize your investment should you buy a fish finder for small boats.


We don’t know what you’ll do if your fish finder does not come equipped with a transducer. And we take this chance to talk about how a fish finder works, to begin with.

Your transducer is what’s responsible for sending out and receiving the signal from your device. Once the signal is sent out, it reaches whatever objects and fish depending on its depth and range and then that signal is received right back and interpreted on your screen.

So, what you need to watch out for are your fish finder’s cone angle and frequency. These things determine the effectiveness, efficiency, and versatility of your chosen device.

Some devices operate in multiple frequencies enabling you to have dual zones. Usually, the wider zone with lesser detail and the deeper zone but with hyper-visualized details. Choose wisely depending on your needs and frequent fishing spots and style.

Ergonomic Design

A fish finder needs to be portable and be easy to handle. Especially when it comes to these smaller handheld models that we’ve discussed. While most of them can probably be mounted properly even on smaller boats, it’s better if you can hold them firmly.

An ergonomic design refers to how the body is designed that in such a way you can wield them as you go. That’s all the while operating some other tool or maybe your fishing rod on your other hand.

Also, an ergonomic design would refer to its screen. It should be readable enough at all times, no exception. Whether the weather gets bad, it gets slippery, messy, or it gets extremely bright. Choose a unit with a readable screen even in extreme conditions.

Add-on Features

While add-on features can increase the price of your fish finder a little bit, they will come in handy. Devices with built-in GPS features will aid you a lot. You can make maps, create waypoints, or use them as an emergency tool to get you back home when it gets tough.

And trust us, it can go downhill fast when you’re out fishing especially in poor weather conditions.


Of course, there’s no point in high-tech features if the unit is not built to last. It should be constructed that in such a way it’s rugged and made out of the finest materials for endurance. The devices we listed are fit for ice fishing so you know they are tough.

Frequently Asked Questions

What are the Different Types of Fish Finders?

There are 3 common types of fish finders. You have the older 2D fish finder that operates mostly in black and white as these are the first iterations of the device. And then you have the two most common types utilized nowadays.

We’re talking about the side scan and down scan fish finders. As their names imply, side scan fish finders have a wider range up to about 100 feet on both sides when it comes to the details it can present.

They are mostly utilized in freshwater fishing or shallower bodies of water but do take note that sometimes, devices that have a wider range will have lesser details. But that’s not in any way saying that these side scan fish finders have not been innovated to still provide photographic images.

Down scan fish finders will have more depth so they are, of course, utilized more on saltwater and they provide better details.

Also, there’s a somewhat fourth type of fish finder that some of the devices we listed above are categorized into. It’s a hybrid device and will have both side and down scan properties.

How do I make sure to properly utilize my fish finder?

Well, first you need to make sure you know how to operate it especially its interface. Some modern fish finders will have all sorts of symbols on their screen so familiarize yourself with what they mean.

Make sure when to know how to choose the right settings so as not to go on auto-mode all the time. Sometimes, operating on auto won’t get you the desired results.

Get to know sensitivity, range, zoom, color pallets, and screen settings more and more as you utilize it.

Any Maintenance Tips to Prolong the Service life of my Fish Finder Device?

Take note that the waterproofing rating of your fish finder has a limit to it and so don’t be overconfident on either submerging it in water or cleaning it under running water forcibly.

Only use a little amount of soap with your water if it’s really dirty and only use soft microfiber cloth so as not to damage the screen. Also, make sure to take care of your transducer and other components.

Especially when operating on saltwater, the components of your fish finder may suffer from corrosion. Make sure to spray, wax, or grease them with anti-corrosives regularly.
