How to Determine the Best Fish Finder for Yourself

fish hiding in coral


It is your ears and eyes in the water as it transmits the signals and deciphers the feedback. The ideal type of transducer is highly linked to the type of fishing you intend to do and the fish finder you are using. Different approaches are needed depending on compatibility and the type of fishing.

For instance, a wide cone angle transducer will be ideal for topwater fishing, while a narrow angle is perfect for deeper angling.


The larger the display, the more you can see, so naturally, you should go for the largest you can accommodate in terms of budget and space. A big one may not fit in your boat or will unnecessarily cram up your vessel.

You should also consider other display elements, like screen resolution, color, and contrast. A backlit display also comes in handy in situations of low visibility.

Portable or Fixed

This choice is also pegged on the kind of fishing you will be engaging in and whether you have a permanent place to fix the fish finder. A fixed fish finder will give more consistent readings, but not all circumstances are ideal for fixing.

GPS Integration

GPS is crucial in navigation as it will enable you to fish even in waters you have never been in. It also keeps you constantly aware of your location so you can trace your way back to where you began or return to the same spot later if it was fruitful. Many fish finders nowadays are integrating GPS because of this convenience, some with built-in maps.

It may not be very critical to have, however, if you are not venturing into the water but are fishing from the shore or waterfront.

Down Scanning vs Side Scanning

  • Down scanning captures what is directly underneath the boat. The angle is narrow, but the pictures are sharper, meaning it is ideal when you have already identified a spot, and when you want to go deep.
  • Side scanning covers the sides of the boat and is more expansive. It captures the general terrain, which is great for shallow water fishing.

Some fish finders have both, which gives them an edge because they can be used for both purposes, separately and concurrently.


A quality fish finder should last a long time, longer than your other fishing gear, because it is not tackling the fish directly. Indicators of long-lasting fishing gear are water resistance items, especially since the transducer needs to be in the water, the finishing touches, and how easy it is to operate.

You should also peruse the manufacturer’s warranty as it usually reflects on their confidence with their product. The average warranty period for fish finders is one to two years.

What Makes the Humminbird Helix 5 Outstanding?

What are some other features and advantages that really make the Humminbird Helix 5 stand out for anglers?

Dual Beam PLUS Sonar

This refers to combining two beams: a narrow one that focuses on a specific point, giving very detailed and accurate coverage of the terrain, and a wide one that covers a larger surface to help picture the surrounding. You can view the results separately, next to each other, or blend them to get the whole image.

SwitchFire Sonar

It refers to the ability to switch how your returns are displayed, depending on what you want to see. Different display modes will give you various perspectives, enabling you to get a clearer picture of the water’s depth, turbulence, and many other variables.

These two features are enough for a decent fish finder for the bay, shore, or riverbank fishing, such as the Humminbird Helix 5 Sonar G2, which will be relatively cheap yet functional enough as you won’t be moving around much. It even has a portable version that comes with a custom portable carrying case, the Humminbird Helix 5 Sonar G2 PT.

The two fish finders are the pioneers in this series and did not even have GPS or any form of navigation features. We put together an additional list of portable fish finders if.

CHIRP Digital Sonar

The newer Helix 5 series models are much more advanced since the introduction of Compressed High-Intensity Radar Pulse (CHIRP)digital sonar. This covers a wider range of frequencies, giving more elaborate readings and enabling you to see more details than you would with other sonar devices.

The accuracy of CHIRP Digital Sonar has made other improvements to the Humminbird Helix 5 fish finder series possible; The latter models have a built-in Humminbird Basemap, AutoChart Live, are LakeMaster Compatible and Navionics compatible.


Map Studying

The Humminbird Basemap

It is in-built in all post CHIRP Digital Sonar Humminbird Helix 5 fish finders. It is based on NOAA data (The National Oceanic and Atmospheric Administration under the U.S. Department of Commerce).

The NOAA supports marine commerce, monitors climate and weather patterns, and manages fisheries. This makes it easily the most reliable source of data. The Basemap gives an accurate description of the underwater terrain and points out the areas of interest. The charts cover most of the U.S and parts of Canada.


This is Humminbird’s improvement to the Basemap, providing higher definition details that are even more exact. Imposing this on the Basemap sharpens the accuracy, and you can better see the contours and estimate water depth.


This is a boating app that provides boaters all around the world with electronic cartography for navigation in marine areas, lakes and rivers.

It has been reviewed several as one of the best navigation apps in the market today. It is a definite plus if it is compatible with your fishfinder.

These three enable you to eliminate unproductive water and only focus on the best fishing spots, saving time and resources in the process.

AutoChart Live

It is a feature that lets you create your own maps from experience. You can save the contours encountered, the lay of the underwater terrain, your best fishing spots, and the routes taken. If you combine this intelligence with the Basemap and LakeMaster features, you will greatly eliminate guesswork from your fishing and spend more time actually fishing.


CHIRP Side Imaging

A signal is sent with CHIRP Digital Sonar precision on both sides of the boat, covering up to 480 feet. It gives a clear view of the lay of the waterbed surrounding you. Combining side imaging allows you to filter out unnecessary noise and only focus on what is relevant.


CHIRP Down Imaging

This time the signal is sent downwards to cover what is beneath your boat. It has the same CHIRP Digital Sonar accuracy that provides clear and precise images while. You can discern between underwater structure, vegetation, and fish. It also lets you know the water depth and shape of contours beneath you.

Though it is relatively new in the market, we have considered it on the grounds of its relatively fair price for a 7” screen fish finder. It is also a color screen, albeit a WVGA (the Humminbird Helix 5 is a TFT).

It also uses a CHIRP Sonar and has all the usual perks like built-in GPS and mapping software. It is worth checking out.
