Whether fishing out of your kayak after work, on the boat for the weekend, and or on the ice in winter, you need the best portable fish finders for everywhere you fish. And just because you fish different ways doesn’t mean you need different fish finders. The best portable fish finders are adaptable and powerful to cover the water wherever you fish.

The concept of a fish finder is nothing new and pretty basic—a device that helps you determine structure, depth, water temperature, and, of course, find fish. Traditional fish fish finders are permanently mounted on the boat with a transducer on the bottom of the hull. But modern fish finders have revolutionized the game, allowing anglers to take their devices wherever they fish whether it be from a boat, kayak, through the ice, or from shore. I tested out some of the best portable fish finders on the market so you can find the perfect fit for your fishing style.

Things to Consider Before Buying a Portable Fish Finder

There are many choices for the best portable fish finders and great options at every level. To meet the need of anglers fishing from kayak, boat, shore, and on ice, manufacturers are packing the latest portable fish finders with the most modern features like live view sonar and premium charts. And they’ve perfected keeping the control unit, battery, transducer and other accessories compact enough to fit in a take-anywhere carry case. 

To pick the best portable fish finder, consider how you will use the sonar and navigation system. For shore and kayak anglers, a basic system with sonar and GPS plotter is easy to install and transport. However, anglers looking to carry their portable fish finder from boat to ice to kayak will appreciate the advanced live and scanning sonar and premium charts. Here are three things to think about when choosing the best portable fish finder.

Fish Finder

The most obvious consideration is choosing the best sonar for your fishing. Portable sonars are available with the most advanced side-view and live-view sonar offering a photo-like image of fish and structure below the water. But anglers looking to save some money and space in the boat can get a small color display and basic GPS for a bargain.

GPS

In addition to finding fish, the best portable fish finder will help you find your way to fishing spots and back home. Whether you need a basic GPS plotter to mark hotspots or want navigation charts with advanced features and detailed depictions of underwater structure, the best portable fish finders include accurate navigation information, a valuable fishing tool and an extra layer of safety.

Portability

Portable fish finders are more than just a fish finder in a bag. They need to be versatile, allowing anglers to transport them easily and use them in any situation. The carry case or shuttle houses protects the control head with room for accessories and battery. To go from boat to kayak to the ice, the best portable fish finder will have attachments that make it easy to install the display and transducer. After all, the most important job for a portable fish finder is going places.

Methodology

The best portable fish finders, well, need to be portable. The idea of being mobile while still performing at a high level was at the core of my testing. A reliable portable fish finder needs to be able to take abuse in all different environments and fishing styles without blinking an eye. For each category, I compared apples to apples, looking at the most popular models with similar features and price tags to find the best portable fish finders at the best value. Then, I took to the kayak, boat, and even onto the ice to test how the parts came together for easy operation and effective performance.

Size: How well does the display, transducer, and accessories fit into a portable carry case?

Performance: Does the fish finder give accurate readings of structure, water temperature, and depth?

Durability: How well does the fish finder take abuse? Can it withstand being transported from boat to kayak to the ice shack?

Setup: How difficult is it to setup and transport?

Value: Does the quality of the fish finder match the price tag?

FAQs

Q: How much do portable fish finders cost?

Portable fish finders range in price from just over a hundred dollars to thousands of dollars. Of course, most of the price is in the control unit. A large nine-inch touch screen display costs more than a two-inch screen. Adding an advanced sonar and premium navigation also increases the price. An advanced sonar will require a more powerful and more expensive transducer to send and receive the signal. Portable fish finders come with a carry case or shuttle and other accessories, which can add to the price as well. Manufacturers sell the case, display and transducers separately, but you can save some money by purchasing a pre-packaged portable bundle.

Q: Can you use a fish finder without a boat?

Yes. The best portable fish finders will be just as useful from a boat or kayak, but anglers can certainly use a fish finder without a boat. If you are fishing from shore or on the ice, you still have options for electronics. Most portable fish finders can be turned into an ice fishing fish finder by adding a special broadband transducer to produce real-time images of the fish and structure below the water. To use a fish finder from shore, choose a castable transducer and smartphone application (like the Deeper Pro Plus). Then cast the transducer away from shore and it will transmit images of fish and structure to your smartphone.

Q: Do I need a GPS on a portable fish finder?

The best portable fish finders double as a navigation tool. In addition to sonar to see fish and structure below the water, a fish finder with GPS helps you find the most productive fishing locations and safely navigate on the water. But all GPS and fish finder combos are not the same. The best navigation systems offer detailed charts and navigation data. Less expensive models will have less detailed charts best for basic navigation. The least expensive option is a GPS plotter. A plotter doesn’t display maps but saves tracks and waypoints to mark fishing hot spots and important locations. Some anglers fishing from shore, a small boat, or on a kayak may not need a fish finder and GPS combo. While you don’t need a GPS with a portable fish finder, today’s technology makes it easy and affordable to combine sonar with navigation.

Final Thoughts

The most advanced sonar and navigation tools work well on the kayak, boat, ice, and even from shore, allowing you to catch more fish and have more fun. To choose the best portable fish finder, consider how and where you will use the unit. For shore fisherman, a castable sonar allows you to stand on the bank and virtually see through the water to the bottom. For anglers who fish from a kayak, boat, and on the ice, a more advanced fish finder with GPS helps locate fish and navigate safely. Even anglers looking for the latest live and scanning sonar technology will find the top-of-the-line fish finders in a portable package. The best advice for choosing electronics is pick the model with the features you use most often, and a control head and transducer that fit your fishing platform.
