How to Choose the Right Fish Finder for a Pontoon Boat

Transducer Location:

The first and foremost thing that you must consider while going to purchase a fish finder is whether your ponton has a place to put it or not. Basically, the transducer is a sensor and part of a fish finder that is placed into the water. It works on sending the sonar waves and receiving the reflected pulses.

Boat Size:

Well, the size issue of your pontoon matters much while getting a fish finder. That's why you should check your pontoon boat size first. Then check the transducer cable length you want to purchase whether it is compatible with your boat or not. Because it will make a great impact on its performance. 

You will find some cheap fish finder that is made for small boats. As a result, it will not be able to transmit a strong signal as your boat is bigger. If you are confused about your pontoon boat size, then you can check the instruction manual that comes with it.


A fish finder along with a GPS is a blessing. It is recommended to go for the fish finder that comes with a GPS. Because it will help you to find out your position as well as will prevent you from loosing while fishing. You can make your own maps though. A GPS will not make any impact on its performance. Fish finder without a GPS will work fine too. In fact, a fish finder with a GPS feature is expensive.

Get the right sonar:

Well, there are a few types of sonar. The Side-scan, down-scan sonar and mixture of two. Which one you should get? The answer depends on some criteria. Let's have a look at these:

  • You should go for the side-scan sonar if you need a fish finder to deal with shallow water. It is not the best for water deeper than 75 ft.
  • The Down-scan sonar is great to deal with the deep waters. It will show tremendous performance in shallow water. This type of sonar has the ability to turn your display into a cluttered mess.
  • The last one is the combination of the about-mentioned two. This type of sonar works fine in both deep and shallow water. They are expensive too.

If you don't have budget limitations, then you should go for the last one that is the combination of both side-scan and down-scan sonars. However, if you have limitations in your budget, then you should go for the specific one.

Screen size:

Not necessary actually. Most people think that the bigger screen is better. There is some situation like display various data metrics or split-screen modes where you can find the bigger screen is beneficial. Here you no need to pay heed much.
