2. Raymarine Dragonfly 4DV Sonar

At first sight, this fish finder looks like a cheap, low quality piece. A closer look at it however reveals a different story altogether. The Dragon 5 from Raymarine is home to some premium features. For instance, it comes with a much-needed anti-fog feature complete with a backlit. If you have been out there fishing during foggy days you can imagine how this feature can get.

Another interesting thing is that you can even check your boat speed right from the screen. What’s more, you can track trolling speeds for fish species and specific lures.

However, its reviews speak otherwise. In fact, majority of its users admit they were surprised by how effective this unit is. For starters, it has a wide variety of settings and scrolling options.

While that may sound like a big turn-off to newbies, the fish finder’s use friendliness overrides all expectations. The buttons and screen are well laid out and easy to grasp.

The screen offers detailed resolution and although it could be bigger and better we certainly think it’s worth its under $100 price tag. Because it is backlit, it means you can easily read the details from every angle irrespective of the position of the sun.

One little feature that makes this among the best fish finders in the market is the advanced signal processing functionality. This completely does away with the need for manual adjustments. It makes it a tad easier to analyze details as you focus on controlling the boat. To make sure you are not shooting in the dark, the fish finder comes with a broadband sounder.

This is a hybrid system as it offers both portable and fixed functionalities. Recommended for small boats, the T-Box comes with a transducer, which is equipped with a wireless module. This module is connected to your phone through an app, which means you can track everything right from the palm of your hand.

The only issue here is that it only works when connected to a 12-volt power supply. So you will need to fit your kayak with a source of power to keep this unit working. At a price that is well below the $200 mark, you get a unit with a dedicated transducer. What that means is that you can transmit images to pretty much any screen.

So screen size is not an issue here. Want a big screen, then you simply need to connect it with your tablet screen. There is really no limit to the screen size you can use. This fish finder operates on 200kHz dual beam which allows you to scout a conical area of up to 40 degrees. For deeper views, this unit allows to analyze depths of 240 feet in fresh water.

That’s obviously more than enough for a beginner. We really like the fact that this unit is highly accurate. Its transducer works like just any other unit you would find in pricier models. When all is said and done, the Vexilar SP200 provides good value for money. You can even use it with a 10 inch iPad screen.

If you were to opt to buy any other fish finder with a 10 inch screen, you would have to spend at least $1,000. So this unit really provides good value for money. 


  • Uses patented WiFi signal to transmit live signal to your device
  • Cell phone network coverage not needed to operate
  • Free app available for iOS and Android systems
  • Easy to use

Small is the new big in the world of fish finders nowadays. The iBobber, is small and petite but wait until you discover that it can any screen size. To start with, this fish finder is app based. This app typically transforms your mobile/tablet screen into a Sonar screen. You therefore get the freedom to scout for fish at the comfort of a screen you’re familiar with.

That’s not all, the iBobber gives readings of up to 135 feet deep which is absolutely not too shabby for something this petite. Price-wise, this fish finder is relatively cheap.

  • Amazing connectivity with smartphone irrespective of carrier network status
  • Can be used anywhere in the world
  • Easy to set up and use
  • Good value for money

If you’re looking for more flexibility, then the 43cv is just what you need. Built with enhanced CHIRP sonar technology, this unit provides high screen resolution. Its ClearVu functionality has a capacity of 1750ft which you will agree is quite deep. To back this up is a high resolution backlit screen which operates on 480H x 320V pixel resolution.

Moreover, the unit operates within the frequencies of 77kHz and 200kHz. The former provides up to 45 degrees conical view while the latter provides 15 degrees. Of course, that range of view is much less than some of the units we’ve seen here.

But all in all, 45 degrees is quite wide – and probably just enough to get you started. The Garmin 43cv runs on a 5Hz internal GPS which makes it easier to plot maps and set locations.

Besides that, it comes with advanced transducer with incorporated temperature sensor. That means you can explore the waters with a bit more data. More data means more confidence and greater chances of large catches. Admittedly, this is a very small unit.

However, given its depth capabilities, you can’t help but admire its performance. What’s more, it has incredible speed scanning abilities. Use it in calm waters and you should be able to track great depths even when cruising at 30MPH. For optimum readings, though, it’s recommended to use it at a maximum of 6 MPH.

Buying Guide

Technology and modern-day fishing are like Siamese twins. It’s almost impossible to separate the two. When it comes to fish finders, identifying one that is capable of delivering the best results is key. With factors like budget and level of experience, it is important to search further. Talking about budget, the best fish finder under 200 could mark a good starting point. But is price the only factor to consider? We delve deeper.


It’s recommended to go for higher frequencies like 200 kHz when operating in shallow water. However, if fishing in deep waters then 50 kHz would work best. What you need to know is that, the higher the frequency, the more details will show up on the screen.


Since anglers operate outdoors most of the time, it’s crucial to consider the power options offered. Units with high wattage are known to be faster. Those with lesser wattage tend to be slower and are recommended for shallower water. As a general rule, the shallower the water gets, the lesser the wattage you’ll need.

Screen Resolution

The pixels your screen displays is an important factor worth considering. Usually, the more the pixels, the greater the detail you get to see. Avoid going for units with less than 240×160 pixels. Anything below that tends to be blocky and vague. Remember, the higher the pixels, the better the resolution. That also means sharper, crisper images.

B/W Vs Color Screens

Black and white screens are still available. However, you should only go for them if you’re operating on a really tight budget. On the other hand color screens allow for greater detail. Such a screen would make it easier for you to differentiate fish from other underwater objects. Quite frankly, color screens make it easier to see and understand what’s going on. 


A transducer is a unit that encodes and decodes sonar waves. A well-to-do transducer is one that translates signals into pictures we can understand. Fortunately, most well made fish finders come with transducers out of the box.

Cone Angles

It is important to go for a cone angle that allows for a wide beam to be illuminated right to the bottom of the water. A cone angle of 20 degrees or thereabout would be enough for a beginner. However, as one advances, it’s recommended to go for 60 degrees. What you need to know is that the wider the degree, the larger the area under cover. That could also translate to more catches as well as less effort on the anglers part. 

Final Word

Considering all the facts, it’s nearly impossible to pick the best fish finder under 200. It seems like most manufacturers have really upped their game. With the entry of smart fish finders, the stakes have only gotten higher. That said, Garmin Striker 4 still rules the charts.

It’s backed by numerous positive reviews edging rivals to rank as Amazon Bestseller. While it is not perfect, we like the fact that it has a highly effective GPS, CHIRP sonar and scaling graphics. We’d recommend trying it particularly if you’re looking for a customizable fish finder.
