Budget Fish Finder Buying Guide

There is an array of varying units out there and with most of them packing numerous additional features, it’s quite understandable for any buyer to get lost when shopping for fish finders.

Plus, you may have to consider the fishing locations and see if the device is fit for it. By knowing the features that you’ll need and ones you can do without, you’ll be able to find the ideal fish finder without having to spend so much.

All that said, the following are some key features that you have to consider before purchasing fish finders:


This is an important component of the fishfinder and is responsible for sending sound waves underneath the water’s surface and gather sonar readings. When these waves are emitted into the water below, they bounce off various objects and gives you an accurate direction of where the fishes are. There are three essential aspects you need to consider when it comes to transducers – they include installation type, cone angle, and operating frequency. You can fix the transducer in various locations, hence it can be fixed wherever it’s convenient for you. Generally, it’s mounted on a trolling motor or a transom. The transducer you pick depends strongly on the cone angle. As such, you should pick one that is ideal for the fishing type you’re participating in.

GPS Integrated

Global positioning systems or GPS is another critical feature to consider before buying a fish finder. By getting a unit with a GPS, locating the best fishing spots and maping your routes won’t be an issue. Also, if you have any favorite fishing spots, it can mark the location for you to easily locate them again. Fishfinders with GPS can also perform both depths sounding and chart plotting. The depth sounder is the device itself and the chart plotter shows your location constantly, eliminating the need for a separate device to know your location. Regardless of which fish finder you end up buying, a GPS will surely improve your fishing experience.


This is another key feature worth looking into when buying fishfinders. You need to pay close attention to its display color, size, detail, and contrast as they’re very important in determining whether or not you can interpret what is displayed on the screen. See how many pixels the unit you’re planning to buy has. Remember the more pixel it has, the clearer and smoother the image will be, which will allow for easy deciphering. Additionally, a color display will not just be pleasing and vibrant, it’ll make it easier for you to read.

Fish Finder FAQs

Fish Finder

If you still have some questions concerning the device, fret not. We understand that purchasing a device like the fish finder can give rise to several questions, especially if you’re new to the device. To help you with that, we have handpicked three of the most burning questions people have about fish finders.

How Do You Install a Fish Finder?

In terms of installation, there are numerous ways to do it. For small boats, the transom mount is the most typical way. This involves securing the transducer at the boat’s rear, right below the water surface. Then you need to fix the power cord either via the rear hull or to the edge of the boat and then connect it with the head unit. The thru-hull method is another alternative way to install fishfinders.

Though a little trickier, this method doesn’t involve any screwing/interference to the boat hull. Here, you just need to fix the transducer inside the boat hull (usually inside a small box full of silicone to make sure no air or gaps exist between the hull and the transducer. This makes it possible to send uninterrupted signals from the transducer and into the water.

How Does a Transducer Work for a Fish Finder?

Transducers are an integral part of fishfinders. It helps in converting electric pulses into acoustic energy or sound waves and back again. Simply put, transducers work by sending out sound waves and then receives the echoes, which the echosounder can read or interpret what is underneath the water surface. You can know if the transducer is working by feeling its face while the sounder is running. If it’s working, you’ll hear the transducer tick or sense pulses.

What Do Fish Look Like on a Fish Finder?

Generally, most fishfinder display will show the same, unless it’s a 3d scan, side scan, or down scan. A fish finder typically displays the bottom surface as yellow. Generally, the unit won’t display any color between the bottom and the surface. When there are marks or disturbances shown at the bottom, it can either be floating debris or fish. Remember that the fish is likely to be a large one if the mark displayed is larger and thicker. Also, if you find any arches, it’s more than likely to be a fish. A large ball is generally a bait ball so you should look out for larger blobs or dots around the ball because it indicates that a predatory fish is nearby.
