Best Fish Finders Under $100

Fishermen and anglers all know that going out fishing requires some preparation and fishing is not as easy as it sounds. We all know that besides all the preparation, knowledge about the species you want to fish and location, you sometimes can’t find the fish in the water, be it at a lake or even in the sea. While some might call it that kind of day and give up for that day, while trying to enjoy, some want to maximize their chances of catching fish. You might belong to one or the other but if you don’t catch fish what is the point of going out for fishing. For that purpose to help you locate fish faster than ever I would recommend you to invest in a quality fish finder, and while it won’t make you catch fish, it will put you into contact with more fish, and that is the point of fishing, fighting with the fish, reeling it in, sometimes it escapes but the times when you catch it, you see that all the hassle was worth it.

While there are tons of fish finders in the market ranging that have super high prices, you have to choose the one that will fit your budget, while delivering the most value for their price.

Sure there are tons of models in the market that are priced under 100 dollars, however, not all of them deliver decent and desirable qualities to make them useful for finding fish.

Today I will provide you general tips on how to find the best fish finders under $100, my top picks, what you should consider, features, and some general knowledge about fish finders.

What You Should Consider?

best fish finders under $100

While you may not get all of the qualities that I will mention under the $100 price, you should know what you look for, and check which one fits more your needs, meaning that you will need to prioritize.

Display – When choosing a fishfinder in the sub $100 price you will not get a lot of choices when it comes to displays, since most of them will have smaller displays, however, always opt for the one that has more pixels, or better resolution. The higher the pixel count of your display the better you will see the representation of the objects that are scanned in the water, and of course, a better refresh rate of the display will result in more accurate results.

Power – This is also an important factor when it comes to choosing a portable fish finder, and it will also depend on the location that you are trying to fish in and the depth of the water there. If the water is really deep then you most likely will need to invest in a more powerful fishfinder. The main indicator of power is the wattage of the device, so you better check that out and see if it corresponds with the body of water you want to fish in.

Frequency – You also have to check the frequency of your fish finder, this means that the more frequency that your device has the more detail will be visible on your screen. As a rule of thumb, if you plan to fish in shallow waters higher frequencies may work better in your regard, however, if you want to fish in deeper waters, a low-frequency model might be more useful for you.

Durability – Since a portable fish finder will be faced with some kind of extreme circumstances most of the time it must be a durable device. The water, wind, freezing temperatures, occasional drops, and different scenarios might damage your device, and if it is damaged right away and has no durability and sturdiness, I would say that it is not worth your investment. For that reason opt for models that boast high quality, so you can have your device working for a long time.


There you have it, my fellow fishermen, your guide to buying the best fish finders in the market under $100. While it won’t be the easiest task, you can get a fish finder that will fit your needs, and whatever you get it will improve your fishing experience significantly. Until next time!
