One of the most important purchases you will make when finding fish is a good fish finder. There are four features that fish finders should have in order to be effective and reliable. 

Display Size

The display size is perhaps the most important feature of a fish finder. In fact, this is where many fish finders differ from one another and why you should consider display size before making your purchase. The larger the screen, typically means that fish will be easier to spot on it as well. There are various sizes available for fishfinders but typically they fall into these categories: 

  • Standard Screen 
  • Medium Screen 
  • Maxi Screen

It’s a very important part of this gadget. Among all the fish finder benefits that make you want to invest in it, it’s important to have a big screen because of the better perspective of what goes on under the water. You won’t have trouble fishing afterward. 

Screen Resolution

The resolution of the screen is something you should always consider. The better the resolution, the easier it is to spot fish and other objects on the screen. The resolution of fish finders varies from model to model, but a good fish finder will have at least 480 by 640 pixels.

If you have a clear picture on your fish finder screen, you will not only have the ability to see fish better but also be able to determine their species more easily.

It is important that they are used with a clear resolution because if fish are difficult or impossible to spot on a low-resolution fish finder then it can’t really help you in locating fish effectively. When fishing under different weather conditions knowing exactly where fish are at all times makes catching them much easier and efficient for both experienced anglers as well as beginners alike. 

Fishfinder Type

There are different types of fish finders depending on the fishing activity. Some of them are used for ice fishing while others work best in deep water conditions. The type of fish finder to buy should be determined by what you often use it for and where you usually fish.

A handheld fish finder is ideal if you do not have much space or storage room available as they require little maintenance, power source, etcetera. On the other hand, portable fish finders can also offer excellent depth range considering their size which distinguishes them from other types of fish detectors that only operate at a certain depth limit before losing signal strength.


Finally, the amount of money you’re willing to spend on a fish finder should be taken into consideration. If you want the best fish finder on the market, then expect to pay $200 or more for it. However, there are many available at much lower prices that still deliver great quality and performance.

Look into reviews and comparisons to make sure you’re getting the fish finder that best suits your needs.
