Why Use a Fish Finder?

Fishing is a sport that helps man return to the basics and nature. Many years ago, man had to survive by hunting and catching food. There were no stores or restaurants. Ancient man found ways to make it happen. Today, people may not rely on hunting and fishing for survival, but fishing allows you to reconnect with nature. Using a fish finder seems counterproductive to some, but it really does make the whole experience more enjoyable. The reality is that you can’t catch fish if they aren’t there, and being able to know whether they are or not saves a lot of time. In today’s world, time is limited, so having a fish finder makes a world of difference.

How to Choose the Best Fish Finder

Fish finders are made up of two parts: the display and the transducer. From there, they vary in terms of added features. When you are choosing between the different models, there are different features to consider. Take a look at the following:

  • Personal Preference: It is really important to understand your personal fishing habits, and decide what is important to you in a fish finder. Consider the add-on features, and realistically decide whether you will use them. Generally speaking, you are paying for the extra bells and whistles, so make sure that you are actually going to use them.

In addition, determine what size you want, and whether you want touchscreen capability, and if the coloring matters to you. If you do any specialized fishing, do you need additional features? There are fish finders with just about every option out there, so think about what you do and what features might benefit you.

  • Its Accuracy: When you are considering which fish finder is right for you, you want to make sure that it is accurate. It would be a complete waste to buy a fish finder and have it misguide you as to where the fish are. The accuracy is determined by three factors. The first one is the cone angle, and the most common is 20. However, they range from 9 to 60. This angle matters because it determines the field of view of the fish finder.

When it sends out a signal, the angle determines how far the sound waves can spread out. The greater the angle, the further they can spread, and the more fish it will find. That said, if it is too broad, it will be harder to find fish in deep water, but a broad angle would work well in shallow waters. Determine which would be most beneficial for your type of fishing before you decide. 

The other factors are frequency, which ties to the cone angle. Power is the third, and it determines the frequency. Power can use CHIRP (Compressed High-Intensity Radar Pulse) technology to combine frequencies to get the best picture. 

They are all interconnected, and you need to decide what level of accuracy is necessary for your fishing style.

  • Its GPS Capabilities: GPS capabilities are important for a number of reasons. You can keep track of where you are by marking locations. You can also download maps of water bodies and their underwater topography. You can also connect some fish finders to an app on your phone, which is really helpful for analyzing the data. 

  • Manufacturer: Because you want to have confidence that your fish finder works well, you should stick with a known and reputable brand. Reliability is critical, and there is no reason to test out an unknown brand when you have no basis for comparison. Reputable fish finder brands include Garmin, Hummingbird, Lowrance, and Raymarine. 

  • Affordability: The key here is to find the most affordable, yet reliable fish finder. If you only look at price, you may buy something inexpensive that is lacking in accuracy or that doesn’t have any useful features. It is important to set your budget, but be realistic with it so that you can get the fish finder that is going to work the best for your needs.
