How Does a Fish Finder Work?

best fish finders under $500

Some people don’t believe that fish finders are functional, but I and thousands of buyers can attest that they are super functional and useful. This device works by transmitting a sound wave, which is converted in the transducer from an electrical impulse. So the sound wave travels around the water and when it hits the fish or the bottom it bounces back. Depending on the model you will see fish finders that display the size, shape and even the composition on the fish.

One quality that separates the best from the worst is the accuracy, and that will depend on the frequency and the pulse that is being transmitted while working, and under the $500 price, a fish finder will deliver reliable and accurate findings without any problem. These devices are ultra-functional and are quickly replacing the more traditional hit and miss methods of fishing, such as large maps, and word of mouth.

Features You Should Consider

Just because it is a small device that isn’t used for many different purposes, doesn’t mean that there aren’t a lot of features to consider when it comes to fish finders. I can say that there is a wide range of features to consider, and they will all affect its efficiency and price.

Display – This is one of the most obvious factors and it is the first thing you will see when it comes to specifications and features. For example, a premium display will help you catch more details on screen since its resolution and detail reproduction will be higher compared to other models. Take all that aside, a better display will enhance the overall fishing experience, because you will get the details much faster and you won’t have to look at the screen for a while to figure out what is going on. Also, I would recommend you to go for the biggest screen you can afford to get the best experience.

Power – The power of your machine will mostly depend if you plan on fishing on fresh or saltwater, and if you are shopping for the latter, you should take a look for models of at least 250 Watts of RMS power and 3000W peak to peak, and the higher the better. The indicator of power when it comes to fish finders is its wattage and the larger the number the more powerful your device is. Consider where you are going to fish and its depth before choosing a more powerful machine because you won’t need a super-powerful fish finder if you will fish in shallow waters.

Frequency – This is another factor that will significantly affect the performance of the product, but like the power, it will also depend on the location you are fishing int. For example, high-frequency fish finders are pretty good for shallow waters and deliver better performance for that issue. On the other hand, deep-sea fishermen, and commercial anglers prefer low-frequency devices, at about 50kHz. However, recently we have seen tons of models that come with several frequencies you can choose resulting in a versatile device.

Wireless Connectivity – Most of the fish finders in the market can be connected via USB cables to your computer or smartphone, the better or more advanced models connect to your phone with Bluetooth or WiFi, which adds to the convenience and you can transfer data super quick and painlessly toy our phone.

GPS – The majority of the fish finders these days rock GPS capabilities, which in my opinion is one of the best features. This is especially true if you tend to fish in large lakes or even oceans, which in turn will make it much faster to navigate back to the coast. Besides, that GPS systems will also allow you to mark favorite fishing places, and even check dangerous areas in the water.


This is it my fellow anglers, this is the guide on how to get the best fish finder under $500, I hope that I have provided a good amount of knowledge to you, and now I feel that you are ready to purchase the best fish finder for your needs.
