Whether you go ice fishing, lake fishing, or ocean fishing, the whole point of the exercise obviously is to find and catch fish. However, you can’t see very deep into the water, which is a problem when it comes to knowing where to fish. You also need to know about the bottom contours of the lake or sea bed, plus where obstacles are.
If you go fishing with just your rod, you might never even come across a single fish, at least if you do not know where to look. However, this is where a fish finder becomes useful. These finders use sonar to help map the bottom of the seabed, plus they help find fish of all sizes. Fish finders really are convenient tools and prudent investment for the serious fisher. We are going to help you find the best fish finder by reviewing five very good products, so let’s get to it right now.
Top 5 Best Fish Finder Review For 2021
In terms of moderately priced fish finders, the Garmin Striker 4 Fish Finder is hands-down one of our favorites. It is easy to install, fairly easy to get the hang of, and it can find fish at deep depths, plus it can build bottom contour maps as well.
The Garmin Striker 4 Fish Finder comes in various display sizes. You can choose from a 3.5 inch, 5 inch, and 7 inch display size.

Also, is the Garmin Striker 4 Fish Finder can tell you how fast your boat is going, which comes in handy for several reasons.

This is an interesting fish finder to go with if you are doing small-time fishing, or also just if you are stationary. This is a bobber sonar fish finder that uses your smartphone as a display. It’s quite functional, it’s handy, and it does a great job at what it is built for, plus it’s not that expensive.
The ReelSonar Wireless Bluetooth Smart Fish Finder is a stationary bobber. This means that you just place it in the water beside your boat, and it will float there, gathering information as events happen. It connects to your phone display using Bluetooth.
Some people really like this wireless aspect for convenience and the fact that you can use a simple phone application as the display. However, some people have noted that weather and rough water can affect the Bluetooth connection in a negative way. On a side note, the application for the ReelSonar Wireless Bluetooth Smart Fish Finder can be used on both iOS and Android, plus the app is free.
You can attach fishing line to it so it does not float away from you, although this is not included. We like that the ReelSonar Wireless Bluetooth Smart Fish Finder comes with an easy-to-spot LED beacon; in the event that it gets away from you, at least there is a light on top of it to help locate the fish finder.
This is a very convenient device to use, although it does have somewhat limited functionality. For one, its maximum operational depth is 135 feet. This is OK for lakes and shallow waters, but not for oceans or other deep water fishing applications. Another downfall is that it needs batteries. It has a maximum battery life of 10 hours, although it usually never lasts that long. However, it does have rechargeable batteries, which is beneficial.
With that being said, the sonar readings are very accurate. You will be able to see small and large fish alike, plus you will be able to see bottom contours as long as the bottom of the water is within range of the bobber. Of course, what helps create such accurate and high-quality images is the fact that you are using your smartphone screen for the display.
It also comes with trip and spot logging, weather info, trip info, optional social media share features, fish strike alarms, temperature readings, lunar calendars, and a few other useful features too.
The good part about the ReelSonar Wireless Bluetooth Smart Fish Finder is that it is wireless and it bobs in the water. It also has a plethora of useful features that come in handy when fishing. The ReelSonar Wireless Bluetooth Smart Fish Finder is also not very expensive, and fairly durable too.
The bad part about the ReelSonar Wireless Bluetooth Smart Fish Finder is that the Bluetooth connection does not always work so well. Second, a maximum operational depth of 135 feet is not too impressive. Finally, the battery life on this item is just not that great either.

You can let it float from the boat up to 25 feet from you or you can attach it to a pole or a boat, plus it can be used for ice fishing. It’s quite the versatile fish finder. We like that it is small and portable, because you can easily pack it into your tackle box and take it with you. The fact that you can use it for so many different fishing applications is a bonus.
The Venterior VT-FF001 Portable Fish Finder has a decent display. It’s not huge, nor is it a color display, so it could be a bit better, but it is fairly easy to read, plus it has a backlight for those dark days.

The Lowrance HOOK2 4X Fish Finder features a high-resolution 4-inch color display with a backlight. We like the display because of its large size and the backlight make it very easy to read. The fact that it has a high level of contrast and resolution is very useful. The bottom line is that it is very easy to see fish, the bottom, and all kinds of obstacles. Also, the fact that it is easy to use is another big bonus; many fish finders just are not easy to use, but this one is.

You Should Know Before Buying The Best Fish Finder For 2020
There are a few important things to research before you purchase any fish finder, so let’s talk about these real quicks.
One thing to pay attention to is the angle of the sonar cone. The wider the cone is, the wider the view you will get on your display, thus showing you more information.
There are still good black and white fish finder screens out there. These have the bonus of consuming less energy, but on the other hand, color screens are much easier to read.
Simply put, the higher the frequency of the sonar, the more detailed the images will be. Having a fish finder with multiple frequencies is always a good option.
You want your fish finder to have a lot of power in relation to the operational frequency. The higher the power level, the deeper it can go.
