The Skinny On Fish Finders

In the game of fishing, there is a wide range of cool gadgets, products and tools. The industry has fully embraced technology making fishing much easier and enabling anglers to catch more fish. Whistles and bells have replaced that notion of, “that spot looks good.” However, one tool stands out among all of them, is the fish finder. It leads the way when it comes to definite angler advantage and functionality. Without one, you will be relying on the advice of relatives, friends, and other unreliable sources, to identify potential fishing spots. Worse still, you will be relying on chance, hoping that the spot you have cast your line is the chosen one. With a powerful locator device in your posession, you have an invaluable resource that can create all the difference between that invaluable trophy and coming home empty-handed.

What is a Fish Finder?

This is a sonar instrument designed for the sole purpose of detecting fish in water. It achieves this purpose by detected reflected signals of sound energy. All electronic signals reflected off the fish, are then converted into information. This information is displayed via graphic rendition on its screen. Apart from locating fish, these devices allow an angler to measure water depth, water temperature, locate underwater debris and the view the bottom structure. Moreover, you can use finders to mark product waypoints, which adds to the overall safety of your fishing expedition using GPS technology.

Thanks to this wonderful technology, it is now more easy than ever to find some good fish! It’s possible to get a good catch without electronics as well, but why hold yourself back, you know what I’m saying? Despite the fact that a good finder device can really help you out, it never hurts to know more about manually finding fish. It is especially helpful for newbies, noobs and nubcakes to learn how to find fish, before relying entirely on an automated device. And besides… you are still going to have to learn how to read that nifty device of yours. Can’t expect automation to automate your understanding. But without further ado… let’s continue talking about fish finders!

Which is the Best Fish Finder?

How do you choose a good fish finder? With so many models and brands available today, it can be quite hard to isolate one and say it is the best of all. The best fish locator device should meet your individual fishing style as well as fishing needs. Moreover, you can easily get lost in the world of sonar, transom units, flashes, and transducers. Therefore, the most important question to ask yourself, is whether it will help you to catch more fish. After all, that is your goal as an angler. Regardless of how technically advanced a device is, if it does not enhance and improve the productivity of your fishing, then it is not worth your time and money. To make your work a lot easier, this buying guide will provide you with all the information you need, to help you make the best choice.


This is the main part of a fish finder. It sends sound waves thus allowing you to see what is beneath the water surface. A transducer sends a sonar signal into the water. The signal is then reflected back by the objects that are underwater. The transducer then receives the signal and converts it into a picture. When assessing transducers, the most important aspect to consider is the cone angle. In simple terms, the cone refers to the extent or diameter of a beam sent from the bottom of the boat. It is narrow when it leaves the boat but gets wider as it hits the bottom of the water body.

If you are looking for a bigger viewing perspective, then you should chose a bigger cone degree. With a wider beam, you get more coverage of the target area, which gives you the ability to locate more fish. The main setback of a wider beam is the loss of strength. This means that it doesn’t have great penetrating power, as compared to the narrow beam. Apart from that, it does not provide as clear details as the narrow beam. On the other hand, the narrow beam covers a small extent. However, it can penetrate disturbed or murky waters and still provide accurate details on the structure of the bottom.

To enjoy the best of both worlds, look for transducers with dual beam sonar. They are also known as dual frequency transducers combining both features into one device. Some transducers tend to be more specialized. Some can have as many as 4 different beams or even more. These provide more options and can cover a wider water extent while scouring a lake or other water body for fish. Some brands are sold with these accessories while others need an upgrade. One other option is the Side Beam feature, which will be discussed in detail below.

Side Beam Technology

Also known as side scan, this is a revolutionary design that allows you to see what is happening on the side of your fishing boat. It provides a bird’s eye view of all the details on your screen. These picture-like, amazingly clear images, will provide every detail on either side of your fishing vessel as far as 240 feet. It saves you a significant amount of energy, when would have been spent when using a regular downward transducer. This feature penetrates murky waters easily, showing you humps, rock piles and even schools of fish that couldn’t have known they were there, if you were relying on conventional fishing methods. If you are a serious fisherman or a tournament angler, a side scan is an absolute luxury that can significantly increase your catch quota.

Display – Size, Resolution and Color Quality

The display is mainly determined by the pixels. If your display has more pixels, then you will be able to see greater object details. It is therefore an important feature to consider. However, fish finders that have higher pixels tend to be more expensive. A fish detector with a minimum of 240(v) x 160(h) pixels would be perfect for both beginners and professional anglers. However, the image will appear blocky in this resolution. If you want a better resolution and a sharper image, then you should be ready to invest more.

High definition (HD) screens are among the latest market additions. These realistic devices offer almost the same quality as your HDTV at home, giving you some of the highest realism and best quality available. You will be looking at maps that almost look like real ones. As for the fish, well, you will be able to differentiate them in sizes, and to some extent the variety. Of course, fish finders with HD-enabled screens come at a higher price tag.

Fish finders with black and white displays are also available on the market. They are much cheaper. However, it is more preferable to choose devices with color. Color provides enhanced screen definition, making fish to ‘pop out’ in different hues. This makes interpretation and identification much easier. Color screens also tend to be more visible in bright light. Additionally, viewing them under cloudy or dark conditions makes them produce a brilliant view.

However, that is not to mean that black and white is useless. If you are tight on budget, just go ahead and purchase, and they will serve the purpose to a certain extent. They are better off than nothing.

Screen size is another aspect that comes to mind, when looking at the display. Lower-end and cheaper models generally have smaller screens. This is perfect if you intend to use it as a backup or a secondary device. However, for your main device, go for the largest screen size that you can afford. Don’t, compromise on this. After all, you are buying a fish finder to help you catch more fish. A bigger screen gives you greater viewing surface, which means that you will be able to identify and isolate the fish from other structures beneath the water. A bigger screen also offers better quality. A 5-inch screen is an ideal starting point.


This is another essential feature to consider when buying a fish detector. Power of sonar units is measured in watts. A device with higher wattage is more powerful and efficient. It also has better display speeds and more usable depth. On the other hand, devices with low wattage produce slow readouts. This means that it will take a longer period to receive the readouts of a spot you have just travelled over. Therefore, if you intend to go fishing in deep waters such as the Great Lakes or in various saltwater bodies, then you should buy a more powerful unit. If you are a beginner, a 600-watt fish finder will be perfect for you, as you hone your skills in shallow waters. Serious anglers who are planning on going far and deep, need to look for a device with 1000 watts or more. And in this case, also be sure to bring waterproof pants and a waterproof jacket. Those big catches aren’t letting themselves reeled aboard easily, if you catch my drift.

Fixed or Portable

You can choose either a portable or entirely self-contained unit or a fixed fish detector that you have to mount on your fishing vessel. If you usually rent boats, go ice-fishing of fly-fishing retreats, then you should consider the portable option. These can be used in various situations, are compact in size, and even come with a carrying case thus making travelling a breeze. Apart from that, they have in-built batteries, which are rechargeable. In the portable units, the transducer is already attached to the transom using a suction cup. Portable fish detectors perform the same way as their fixed counterparts with portability being the only difference. On the other hand, fixed fish finders are preferred by the watercraft owners and settled anglers. You can fix the device on any location on your boat. They can be mounted on the trolling motor, the hull or the stern.

Fish Finders and the GPS Option

Any experienced fisher knows that a GPS is a must have. GPS uses satellites positioned in the sky to identify your precise location. With this feature, you can mark product spots then come back later, once you have exhausted the other locations. It also helps in finding your way home easily, especially if you happen to be fishing on unknown territory.

Most GPS-enabled detectors are combo units. This means that they have both a chartplotter and a depth sounder. Chartplotter shows your exact location, superimposed on a map. With this feature, you can always pinpoint your exact location. A GPS-enabled fish finder also allows you to enter waypoints easily. You can use waypoints to mark all fish locations. If you are into big-water fishing, then you should have a GPS-enabled device. It will open up a completely new world of fishing opportunities and fun.

It is clear that devices for location fish, are great additions to your fishing gear. With one of these, you are guaranteed higher catch rates in the fishing world. A large catch is what everyone desires, strives and looks forward to, whenever you go fishing. Happy fishing!
