7. Furuno FCV558 – Best Operating Frequency Fish Finder
Humminbird might be the king of fish finder industry but that doesn’t mean a well-designed, top-end fish finder from a less-famous brand cannot challenge the throne. Furuno FCV558 is a worthy candidate for the slot; delve deeper and you’ll also reach the same conclusion: the best top-end fish finder under $2000.
The unit doesn’t come with a transducer, which makes things costlier, but it’s compatible with a 600W or 1000W transmitter thereby giving you the liberty to choose the equipment according to your fishing plans. Just a bit of temptation though, the unit has a reach of admirable 400m when powered by a 1000W transducer.
Moreover, it’s not a chirp-induced device, rather works on dual-frequency (50/200kHz) sonar which is so good in bringing desired results that you don’t feel any loss. At 50kHz, it’s going to work wonderfully in offshore fishing, bringing back astounding details about bottom and fish.
It comes with an 8.4” screen, that in my opinion is perfect; not frustratingly small nor ridiculously large. The size is good to let you enjoy the underwater show in sparkling colours.
Note that it’s not a chart plotter so navigational features aren’t included. But, there are other amazing functions like Zoom, bottom determination and lock to give you all the information you want to know about the world below. A few tweaks and taps, and BINGO!

Buyer’s Guide: By Getting to The Best Fish Finder in 2021
There are a few ingredients that are vital for making a fish finder the best. Knowing about them is as crucial as having a fish finder in the first place because only then will the selected unit survive the applications you have in mind. These are:
Transducer
The transducer is the heart and soul of the whole product as it houses sonar beams that garner the information. Power of the transducer and sonar frequencies will determine the depth and shallowness range of the unit. A transducer up to 300W will work best in shallower waters. Anything above that power will be safe for deeper exploration.
Similarly, the frequency range also helps determine the appropriate use.
Frequency
Frequency describes the power of the sonar rays. High-frequency means sonar waves will not delve deeper but will carry large detail. This is good for shallow water fishing. On the other hand, low-frequency rays can travel hundreds of feet deep, near the seabed, but the scan returns with lesser details. Such units are suitable for deepsea fishing. Many models employ dual-frequency to help you get the most out of a single unit, wider coverage and optimum details at once. Buying such a unit will diversify the functionality.
Display
No matter how powerful the transducer is or how impressive the sonar functions are, a fish finder without a brilliant display is just a piece of junk. The size of the viewing window and the image quality will make or break your game. A fish finder with 5” or larger screen laden with coloured palettes will exhibit a bright and intelligible view the activity below water. Also, the backlit screen will make sure that image visibility doesn’t get compromised due to outdoor lighting situation.
Other Features
It’s always helpful to look for a feature-loaded fish finder, especially when you’re willing to spend hundreds of bucks. Performance-grade features like GPS, built-in charts as well as networking support will enable you to get the optimum outcome of every excursion without enduring unpleasant incidents.
Price
It’s simple math, the higher you will go the fish finders’ class range, the higher the price will go. It will be wastage of precious bucks if you spend hundreds of bucks on a feature-loaded device, half of which you’ll not even have an opportunity to use, for occasional getaways. However, if you’re in fishing business or a hardcore angler, high-costing unit laced with cutting-edge technology will keep you at the top of your game.
Conclusion
Now that we have established the fact that fish tracking isn’t an arduous task as long as you’re assisted by the best fish finder; the only onerous challenge is to find a unit that talks the talk. Lucky for you that our above reviews cover a diverse range of fish finders, all designed to supersede each other in quality and performance. You will have no confusion whatsoever about picking the appropriate product once you go through the buyer’s guide given at the bottom.
