7 Tips to Choose A Fish Finder


Are you looking for the best fish finders? Are you in need of a more accurate and advanced fish finder for your fishing trips? Fish finders have become important fishing devices for anglers. They identify possible locations where fish are concentrated and makes it easier for you to fish from a boat. In this article, we discuss tips to help you choose a fish finder.

1. Power

One of the first things to pay attention to when choosing a fish finder is the power it provides. The power of the fish finder is measured in watts. The power indicates the strength of the sound waves that it will send out.

The amount of power determines the reach of the “pings” that are sent out by the transducer. How much information the fish finder gathers also depends on its power. Therefore, the power of the fish finder is very important. The higher the power in watts is, the better. You can easily find fish finders with power ranging from 100 to more than 1000 watts.

2. Transducer

The transducer is another important part of the fish finder that you should become familiar with and learn which type of transducer is in the fish finder that you want to get. The transducer plays a key role in the functions of the fish finder.

It sends out and receives sound waves that carry information about the area under the water where the fish reside. It is this device that collects that information about the whereabouts of the fish and displays it on the LCD screen.

The more accurate the readings, the better the information that will be displayed on the screen about the fish underwater. There are transducers that emit single, dual, and multiple frequencies. The transducers that emit dual and multiple sound waves produce more accurate readings.

3. Screen Size

The screen size of the fish finder plays a major role when you are fishing underwater. The larger and clearer the screen, the better you will identify the locations where fish reside and have a good chance to catch them.  There are many sizes of screens and you can easily find them in the range from 3.5 inches to more than 12 inches. The most important thing is to choose a screen size that will work for you and help you catch more fish.

4. Resolution

The resolution of the fish finder’s screen is very important as it determines how clear the images will be on the screen. The resolution is measured in pixels. How many pixels you need for the resolution depends on how far deep underwater you will be fishing. The deeper you go into the water, the more pixels you will need.

Like the squares on a checkerboard, the pixels on LCD screens are arranged in vertical columns and horizontal rows. The measurement of depth and the separation of underwater suspended items like fish are done by the vertical columns. Each pixel reflects less linear depth as there are more pixels in each column, allowing things to be displayed on the screen closer together.

5. Portability

The portability of the fish finder is also important.  There are fixed fish finders and portable ones. Today, most of the fish finders you will see will be portable fish finders.  This allows you to use them in boats, kayaks, canoes, and other vessels while fishing.

It will all come down to your preference but most likely you will want a portable fish finder that you can take with you from one vessel to another and not the one that is physically attached to a vessel.

6. Durability

The durability of the fish finder is also very important. You want a durable and long-lasting fish finder that will withstand the rigors of fishing. The fish finder may have a few drops in water and in the boat during its lifetime and a rugged fish finder will withstand this rough treatment that may be very frequent.

Most fish finders are constructed of durable plastic for its body which makes them very durable and can withstand drops, accidental step-on, and many other accidents.

7. Water-Resistant

Most fish finders are built to be water resistant as they will be in contact with water regularly and may often fall into the water. Most are also designed to be corrosion-resistant and this allows you to fish in both freshwater and saltwater.


Fish finders are very important and useful devices for anglers when fishing today. They are the eyes under the water that displays on a screen just exactly what is underneath the water.

Fish finders make it easier for anglers to get a good idea of what underneath the water looks like and this information helps them to be successful in catching more fish during their fishing trips.

In this article, we discussed tips to help you choose the best fish finders for your fishing trips.
