Over the years, professional fishers have devised various ways to make the most out of their fishing. Aside from the use of small boats and kayaks, anglers have also begun to make use of pontoon boats. While you may be wondering about the importance of “larger” (pontoon) boat in the fishing scheme of things, the fact is that pontoon boats could be favorable for fishing. Among the many reasons for adopting and using it for fishing is because of the larger size that can contain many anglers, multiple storage spaces for the fishes and gears, as well as a fantastic overview of the river in the course of fishing.

The fish finder, which is also called the “sounder,” is an instrument that is primarily used for locating fish underwater. It does so by detecting the reflected pulses of sound energy. Recently, the fishfinder is designed with display measurements of reflected sound, which are brought forth in a graphical display. Such a designer empowers the angler or the operator as the case might be to use the graphical display/information to identify the locations where fishes are underneath the water. It’s also possible to use the same information to interpret the bottom of the body of the water and the underwater debris.

The functionalities of the fishfinder are many, and those are part of the reasons why many fishers/anglers are keen on using it anything they go a-fishing. The most significant of it all is the integration of a GPS/navigation, the compasses, and the marine radar.

The transducer of every pontoon boat is located on the bracket underneath the tubes. However, you needn’t work on assumptions, because your boat might have its own in another place. Therefore, double-check to be sure of the location of the transducer in your pontoon boat. Also, ensure the space is enough to accommodate the fishfinder.

  • Size of the Boat

The pontoon boat is not like the kayak or other smaller boats that you can easily keep things within reach. Because of the width of the pontoon boat, you must ensure that the size and the choice of a fishfinder correlate to the size of the boat.

The measurement is that the fish finder should be visible from the primary fishing location on the boat’s deck. Also, you may want to go a fishfinder with a screen size of 7 inches, because that makes it possible for you to see from the rear-facing fishing seats up to the console where the fishfinder was mounted.

If on the other hand, the boat is larger up to 22 inches, then you may want to attach an extension cable from the transducer to the fishfinder. That is usually the case because the cords attached to the fishfinder might be shorter when the pontoon boat is larger. Hence, extending it is the perfect way to reach it to the location you intend to use it.

  • GPS Integration

The last but not the least is the integration of the GPS that enables the movement while on the water. Using GPS is essential because it does not only make it easier for you to locate fish on the water but also makes it possible for you to have real-time information about the environs.
