What Are the Important Considerations When Buying This Product?

  • When buying a fish finder for a pontoon boat, you have to consider the size of the boat. You want your fish finder to be readily visible from the locations where you are going to be fishing, so you don’t have to keep walking over to the unit. This Humminbird has a seven-inch screen that is clear and easy to see.
  • The location of the transducer is another important consideration as you want it to be close enough to you that you can easily spot fish. Most people put the transducer on a metal bracket along the aft side of a pontoon, which places it a long way away from the front of the boat. This unit is so powerful that you won’t have problems transmitting, no matter where you place the unit.
  • It’s also important to consider how your fish finder will work with other electronics that you are going to be using while on the water. Interfacing correctly is essential if you want to get the most out of your fish finder, mainly if you are thinking about buying a wireless trolling monitor in the future. Knowing that your fish finder will work well with future equipment is essential.

Why We Chose This Product Over Others

We chose this Humminbird fish finder over all of the other available fishfinders on the market not only because of how easy it is to set up and to use but also because it is sized perfectly to work on a pontoon boat. While it’s much easier to buy a great fish finder for a smaller fishing boat, when you are going to be fishing off of a pontoon, you have to make sure that the fish finder will be visible and sturdy enough. This Humminbird fish finder fits the bill perfectly and is easy to install as well.

The screen is large enough for you to view it from all over the boat but it’s not so big that you have problems mounting it on the busy console. Pontoons have less area for mounting a monitor, but this one is sized just right to fit comfortably while still offering you unobstructed views of everything going on underneath you. The GPS on this fish finder is powerful, easy to use, and incredibly precise. Additionally, with this fish finder, you will enjoy fantastic cartography with incredibly detailed maps, making it easy to see where you are and under the water no matter where you are standing.

What We Like and Dislike About This Product


This Humminbird has one of the brightest screens that you can buy, which makes it incredibly easy to see everything from a distance. No matter where you are standing on your pontoon you will have a reasonably easy time keeping track of what’s going on in the water, and the ultra-bright display won’t dim in the sun.

Enjoy incredibly detailed maps that show vegetation, contours, and the hardness of the bottom. You’ll be able to distinguish between fish of different sizes easily, so you don’t waste your time chasing smaller fish.

SmartStrike makes it easy to set your parameters and see instant results on the screen, so you don’t have to keep searching for great fishing spots.


The GPS doesn’t show the speed at which you are traveling, which can make tracking your distance and your location a little more difficult.

The included mounting bracket is made of plastic and not the best option for securing this fish finder to your pontoon boat. If you want to make sure that your fish finder doesn’t move around when installing and that you don’t risk losing it, you will likely want to buy a metal gimbal bracket, which isn’t inexpensive.

Why We Feel That You Should Buy This Product

Buying a great fish finder for a pontoon boat can be a little tricky. When you’re in the market for the best fish finder for pontoon boat, you want to make sure that the unit you buy is powerful enough to work in even deeper water, you can see the screen from all over the boat, and that you’ll be able to track your location and your travels easily.
