Tips for Choosing the Right Fish Finder Under 300

Color Screen

Most fish finders have a color screen. However, you will still find some that offer grayscale display. If you would like to pick the fish from the debris, it’s better to choose a locator with a color screen. Majority of color screen displays show over 250 colors.

The combination of the right transducer and color screen will enable you to know whether something you are seeing is fish or debris. A color screen fish finder will also make you more likely to catch fish since you can easily tell where they are hiding.


Fish finders use a transducer to send and receive information from underwater. Some transducers can be installed on the boat. When the information is sent to the transducer, the sonar is sent to the screen. The sonar information is what you will see.

When you have the right transducer, you can easily know what is under the water where you are fishing.

Screen Resolution

The resolution of your screen will determine whether or not the images will be sharp and clear. The resolution is measured in pixels. The more the screen pixels, the clearer the images that will be displayed.

On the minimum, go for a fish finder with a resolution of 240 x 160 pixels. If you can afford one with more pixels, this is even better.


The amount of power a fish finders has is measured in watts. Choose a device that is powerful enough to read the waves as well as provide clear pictures of what is under the water. For example, a fish finder with 100 W at 50 kHz can show up to a depth of 450 feet.

The more the wattage, the better.


You should know the frequencies that the fish finder operates in. Generally, the lower the frequency, the more likely the fish finder is to reach deeper insider the water. The higher the frequency, the better the information the fish finder will provide of shallow water.

The best fish finders allow you to change frequency from high to low. If you will be fishing in different water levels, get a fish finder that operates on multiple frequencies.

If you usually go fishing, you need a fish finder. The devices are easy to use and provide invaluable information about the contours at the bottom as well as where fish are hiding. Some fish finders also allow you to map your location and share your fishing images on social media.
