              • Hard to wind up
              • The battery could be better

              We understand that pro fishers set out higher demands on their fishfinder to help them find out big fishes better. For you, this model is our proud recommendation for some good reasons.

              First off, it is powered by lithium battery that can work up to 8 hours of continuous use if fully charged. And this factor is seriously important for those anglers who love spending an entire day in the water for fish.

              The next notable thing is its fish-friendly construction with silver colorway to easily fool the fish and lure them close to you.

              You might notice of its price which is slightly higher than other counterparts here but this already includes an 8GB SD card and removable sun-visor. Turn out, it bangs for bucks and you’ll save some extra time to find a place to buy such fishing essentials.

              A big bonus is its ultra-large display screen size – 7 inches with 800x480 pixels – to let you read data or track the fish more easily.

              Cons
              • Not deliver accurate depth above 6 knots
              • The transducer wire is short

              Pick this if your goal when choosing a fishfinder is to navigate and observe fish more clearly.

              The Humminbird 410210-1 HELIX 5 G2 provides you with an efficient 2D CHIRP Dual Beam PLUS Sonar. This is a big improvement that we like the most in this Humminbird model because compared to other forms of sonar, it shoots higher-frequency beams below the surface to present a clearer, crisper portrait.

              So, whether you’re going to fish in coastal waters, freshwater lakes, or even the ice, the picture transmitted will be always in details with good clarity and no distortion.

              Out of this highlight feature, the device also has some other interesting things, such as the micro SD card slot to save more waypoints or optional maps and the Internal GPS Chart plotting.

              Best For Offshore Fishing: Deeper Chirp Smart Sonar – Castable, Portable Fish Finder

              8.6Great
              Pros
              • Ultra-convenient and multi-functional – feature Wi-Fi compatibility and user-friendly app
              • Allow for creating your own bathymetric maps
              • Time-saving - Take shorter time for scanning
              Cons
              • Pricey

              As the name defines, this fishfinder is specifically designed for offshore fishing. But you might be wondering: “What sets it apart from other offshore counterparts?”

              Well, aside from a 5-year manufacturer’s warranty which makes it more reliable, we find its Wi-Fi compatibility and user-friendly app are two decent features. The unit will generate its own signal to connect to your smartphone to directly display all sonar data there.

              That means you can easily track water depth, fish movements, bottom contour and hardness, and more on a bigger, friendlier screen. Plus, the fishfinder’s sensitivity adjustment can’t be easier.

              You are also allowed creating your own bathymetric maps if wanted. The best part is, the time taken to scan what is underneath the water is really fast, which helps you save lots of time.

              How To Choose The Best Fish FindersUnder $400?

              Traditional 2D vs. CHIRP Sonar

              • Traditional 2D sonar operates on single-frequency bands and has been in the market for over 30 years. It usually features 200 kHz of power transmission.
              • CHIRP sonar was invented nearly 8 years ago and features many highlight points. At the same time, it generates a high number of traditional sonar waves at various frequencies in order to give you more detailed readings about the depth and objects’ image.
              • The choice of this factor is relatively about preference and budget issues because the traditional 2D sonar costs much cheaper than the CHIRP. In fact, it still helps boating anglers find lots of fish.
              • But if you want to track in detail the fish movements, the underwater terrains, and more, invest in a CHIRP sonar fishfinder.

              Display Screen

              Keep in mind that all readings from the transducer will be presented on the display screen. Therefore, it should provide a high resolution – meaning a high number of pixels on the screen for cleaner target separation.

              There are two types of display screen: The black and white, and the color.

              This factor, again, is a preference issue but notice that the black and white is commonly the affordable selection for budget-minded anglers. But it won’t last as long as the color display screen.

              Bonus:

              • Look for a bright, sun-readable display screen if you intend to go fishing in daylight, during summer, or in sunny conditions
              • For night fishers, choose a fishfinder that features visual display screen with backlights

              Which Brands Make The Best Fish FindersUnder $400?

              Garmin

              • We bet that even you’re a beginner, there might be at least one time you’ve heard about this brand – Garmin, formerly known as ProNav. This American multinational manufacturer is currently a leader in the GPS technology realm based on its over 30 years’ experience in the industry.

              Eyoyo

              • For those who are in need of budget-friendly price-efficient fishfinders, Eyoyo is a nice go-to choice. This is a young brand – established in 2016 as a group enterprise, but that is key for their unbeatably affordable price range of products.

              Humminbird

              • Humminbird has been always a reputable name in GPS technology and the outdoor device industry. It is owned by Johnson Outdoors Family, who is also the owners of many big brands, such as Eureka, Ocean Kayak, and Old Town.

              FAQs

              Are fish finders necessary?

              Yes, they are.

              Here are some typical reasons why every angler should buy one for their boat:

              • It saves time and energy while eliminating the guesswork when you try to know what kind of structure underneath your boat as well as the depth.
              • Allow you to find flat areas or structure faster and more easily
              • Help navigate your bait when it’s difficult to find by naked eyes on the surface

              How fish finders work?

              Through the transducer, your fish finder sends out sonar signals. Once these signals reach the fish or an object underwater, they will estimate their depth and size, then, display such readings on the screen.

              How long do fish finders under 400 last?

              Commonly within 2 to 12 hours.

              Can you see fish on down imaging?

              Yes, you can.

              Down imaging fishfinders use the transducer to generate sonar waves down beneath the boat to estimate the objects’ depth and size. You’ll see their image presented on the screen.

              Is side imaging better than down imaging?

              Just in some aspects, such as the image and point-of-view of the underwater environments or when you go fishing in those water conditions with many creeks and shallow bays.

              Conclusion

              After months of fishing in a wide range of water conditions with these fishfinders, chatting with each other, and compiling information, we have come to the final choices and awarded our winners. Hope that this guide has helped you find out the best fish finder under $400 more easily.
