If you’re looking to find a great fish finder on the market today, it is important to keep in mind some of the top things you need to look for and keep in mind as you make your decision. When it comes down to it, there are a lot of factors that contribute to making up a great fish finder and the ones mentioned below are some of the most important ones to remember.

As long as you pay close attention to these features, you will have no problem getting the best fish finder to meet your needs.


As you begin to look at the different fish finders, you will find you have a couple different frequency options to choose from including a single, double or multiple frequency options.

Overall, you’ll find that the frequency is incredibly important and will most likely be one of the most important factors in your decision. The higher the frequency, the more detail you will see on your screen since more sonar waves are used.

If you prefer to fish in shallow water, then you will want to find a higher frequency fish finder. However, odds are good that you might fish in a couple different water depths so you will want to find one that has multiple frequencies to choose from.


Like just about anything you plan on purchasing, the power offered by the fish finder will heavily depend on how much you are going to use your fish finder and also where you plan on using the finder once you have purchased it.

The higher the wattage on the unit your purchase, the quicker you will be able to see the readings and the deeper you will be able to go on the water. If you choose to go with a lower watt model, then it will take longer to show the readings and it won’t work as well in deep water.

As you might have already figured out, the deeper the water, the more power you’re going to need, so be sure not to sell yourself short just to save some money because you will regret it if you decide to head out on deeper water. 

Screen Resolution

The next important thing for you to keep in mind is the screen resolution because the more pixels you have on the screen, the clearer the reading is going to be and the easier it will be for you to see what is going on.

If you want to get the clearest and sharpest image imaginable, then you want to find one with a ton of pixels. At the minimum, you should look for a screen that has a resolution of 240 x 160. However, it will still be a blocky image at that resolution so you might want to go higher than that. 

If you are looking for a main unit when it comes to a fish finder and this is going to be the one you use the most, I highly recommend spending the extra money to get a better resolution because you will be able to see everything as clear as you need it to be.


One of the newer and more emerging technologies in electronics with screens is color and it really helps in a fish finder because it can show millions of colors as opposed to the basic shades of gray that you used to get with a black and white screen.

Thanks to the color, you will get better detail and a clearer image of what is happening under the water. Additionally, the color screens are much easier to see in bright light which is a great feature if you fish during the day when it is sunny outside.


One of the next things you need to keep in mind for a fish finder is the transducer because that is exactly what is going to help emit and receive the sonar waves produced by the fish finder. This is going to help send the waves into the water that will bounce off the objects found underwater.

Once it hits an object, it will bounce back to the transducer and those waves will be converted into a picture to clearly demonstrate what is happening under the water. Most of the fish finders you will see on the market are very easy to mount and require little to no installation. 


As you can tell from all of the information outlined above, there is a lot of thought and consideration that needs to go into choosing the right fish finder and you want to make sure you consider each and every point.

By following the information provided above, you will have no problem getting the best results possible and ensuring that you pick out the best fish finder to match up with your wants and needs.
