Hello and welcome to our website. If you’re looking for a fish finder for your small boat, you’ve come to the right place. We have gathered all of the information that you need about finding the best fish finder for your boat in this article, so read on!

A fish finder is a device that uses sonar to detect objects underwater. It sends out sound waves, and when they hit an object, they bounce back and are picked up by the fish finder. This information is then translated into a image on the display, so you can see what’s below your boat.

There are different types of fish finders available on the market, but all of them work in basically the same way. The most important factor to consider when choosing a fish finder is how it will be mounted on your boat. Some models come with their own mounting bracket, while others require you to purchase one separately.

How to Choose The Best Fish Finder For a Small Boat

  • Water Resistance Rating

One important factor to consider when purchasing a fish finder for a small boat is how water resistant the device is. You don’t want to end up with a pricey paperweight if your boat takes an unexpected dip! Devices that are labeled as “waterproof” can withstand being submerged in water, while those labeled as “water resistant” can handle light rain or splashing. Make sure to check the IP (Ingress Protection) rating of any device you are considering; the higher the number, the more water-resistant it is.

Most good quality fish finders will have some degree of water resistance, but if you are looking for something that can really take a beating, then you may want to consider a model that is specifically marketed as “marine grade” or “for boats.” These devices are typically more rugged and can withstand harsher conditions.

  • Power and Wattage

When looking at the power and wattage of a fish finder, you need to consider your application. A handheld device is typically much less powerful than one that will be used on a boat; however, it can still provide useful information about what’s going on under the surface if you are fishing in shallow water or want to do some exploring around your dock.

If you plan to venture out into open waters away from any landmarks (such as rocks or other boats) then look for high-powered devices rated between 50-60 watts per inch squared. If you know where these points of reference are located and don’t plan on venturing too far off shore, then an entry level option may work just fine–you should be looking for a device rated between 25-40 watts per inch squared.

  • Considering Multiple Frequencies

When considering different frequencies, you need to consider whether or not your boat will be in shallow water. If the answer is yes, then you should definitely opt for a device that has both high and low frequency options (ideally 100 kHz and 200 kHz). The higher frequency will provide better detail in deep waters while the lower one works well when fishing near rocks or other objects that could cause issues with a sonar signal at deeper depths.

  • Screen Resolution

Another important factor to consider is how clear the screen will be. If you are shopping for a handheld device, then this likely won’t matter as much to you since it can easily be viewed without an issue; however, if you plan on using your fish finder in bright sunlight or other conditions where glare could become an issue, make sure that any unit you buy has at least 256 colors and high resolution (400×240 pixels).

Some of the best small boat fish finders come with LED backlighting which makes them easier to view when used outside during daylight hours. Most devices these days also have anti-glare filters built into their screens–a great feature!

  • Black and White vs. Full-Color Screens

Most handheld devices only have black and white screens. In most cases, this isn’t a huge issue since you will be using the device to find fish in water; however, if you plan on exploring the insides of rivers or creeks for things like sunken treasure or old bottles, then a full-color display is going to give you much better results.

Full color displays are typically found on more expensive models that are designed for use as boat electronics rather than those meant just for fishing from shorelines or small boats.

  • GPS Feature

A GPS feature can come in handy if you want to mark certain spots where you have had luck fishing in the past or if you need to quickly return to a spot on the river. Not all fish finders include this capability, so it’s important to check before purchasing.

Some units also offer mapping capabilities which can be helpful when trying to locate underwater features or track your progress while out on the water.

If these features are something that interests you, then make sure that the device you choose has either a built-in GPS or an accessory port that will allow you to connect one.

  • Type of Water

The type of water you are fishing in will determine what kind of fish finder works best for your application.

For example, if you plan on using it to look at the insides of rivers or creeks with steep gradients or fast currents, then a device that has both high and low frequency options is going to be ideal–those found on entry level units won’t work as well here because they aren’t powerful enough to penetrate through the strong current.

  • Cone Angles and Beams

When looking at the specs of any fish finder, you will see that it has a cone angle and beam. The cone angle is how wide the signal is (measured in degrees) while the beam width is how far out from the center of the transducer the signal will reach.

The wider both of these measurements are, the more area you will be able to cover when looking for fish. So, if you are fishing in a large open body of water, then you will want a device with a larger cone angle and beam; conversely, if you plan on using your fish finder in tight spaces like creeks or rivers, a unit with a smaller cone angle and beam width would be better suited for your needs.

  • Down Imaging vs. Traditional Sonar

The two most common types of sonar used on fish finders are Down Imaging and traditional (or standard) sonar.

Traditional or standard sonar emits a signal straight out from the transducer, whereas down imaging sends it at an angle so that you can see below your boat; however, some units come with both options to allow for versatility depending on what type of water you plan on fishing in.

Down imaging allows for images of fish right beneath the surface which is great if you like ice fishing since this gives you a clear idea as to how many fish are underneath your hole–especially important during those frigid winters! It’s also useful when trying to pinpoint exactly where fish may be hiding in a certain area.

  • Console vs. Bow Mounted Units

Console units typically have a larger screen that is easier to read from a standing or sitting position; however, they can be harder to see while you are actually on the water since it requires you either bend over at an awkward angle or stand up which could make your boat unstable if not done carefully. Bow-mounted devices do solve this problem since they sit right in front of the person who will be navigating–usually positioned between their legs for ease of use. However, these require additional installation costs as well as wiring which may pose some issues depending on where your battery compartment is located.

Features of the Best fish finder for a small boat

  • Larger display

More brands of fish finders come with a larger screen these days, and that’s definitely something to look for if you want the best possible user experience. A large screen makes it easier to see what is going on below your boat at all times, so you’ll be more comfortable and confident when operating any vessel.

  • Multiple mounting options

If you plan on using various different boats or even just need some flexibility in how often you can use one type of vessel before needing to install another device on it, choose a model with flexible installation options such as those featuring suction cups instead of brackets. This way, changing between vessels won’t feel like such an ordeal!

  • Price range

The price of fish finders varies greatly depending on their features and manufacturer. If possible, decide how much money you’re willing to spend before checking out any product listings so you can narrow down your options accordingly. After doing some research, we found this model priced under $200 which makes it an affordable yet high-quality option perfect for beginners!

  • Depth range

The depth range of a fish finder is the distance from the device at which it can still pick up readings. This is an important feature to consider if you’ll be fishing in deep water, as some models are only able to detect objects at shallow depths.

  • Temperature reading

A good fish finder will also give you a temperature reading so that you can determine whether the area you’re looking at is hospitable for certain types of fish.

  • GPS capabilities

If you frequently go on fishing trips in unfamiliar territory, look for a model that has GPS capabilities so you can mark your favorite spots and return to them easily.

  • Wireless transmission

Some advanced fish finders come with wireless transmission features that allow you to share collected data with other users, such as your friends and family.

  • Diagrams

Some fish finders come with diagrams showing what types of fish are nearby so that you can prepare yourself for likely catches even before leaving shore!

All in all, investing in a good quality fish finder is the best way to enjoy more successful fishing trips. If you’re looking for additional information about various products on the market right now, we recommend following this link !


What kind of battery does a fish finder for small boat use?

Fish finders typically use a rechargeable lithium ion battery. Some batteries allow you to plug the device into an AC outlet or USB port if desired, but many come with their own charging cable and must be charged from within the unit itself. The time it takes to charge your device varies by model.

Are flasher sonar units any good as best fishfinder for small boats?

Yes, Flashers are also known as down imaging or dual frequency sounder that can show depth and temperature at same time along with bottom contour lines on screen which is very useful feature available in this type of Sonars. It has got another feature of showing fish as well.

How far do I need to be from the bottom for best sonar performance?

You should be at least 12 feet away from any object such as a rock, weed line or other structure in order to get an accurate reading on your device. This is because you want it scanning everything beneath and around your boat equally so that every obstacle becomes clear when viewing the screen.

What type of transducer works with small boats?

A thru-hull mount transducer will work well if mounted correctly to provide good water flow and ensure proper coverage area needed by this unit which is required for providing better readings. You can also use portable ones but they are not as accurate.

Is there any way to get a fish finder for small boat that also includes GPS?

Yes, there are many fish finders that include GPS to help you mark fishing hot spots and save them. This information is stored in the device for you to access when you return. You can also use the GPS function to help with your navigation while out on the water.
