Fishing has a lot to do with patience. But there’s only so long you can wait for fish to bite, especially if you went through the trouble of driving all the way to a lake. A portable fish finder takes the guessing game out of fishing. You can spend more time fishing and less just sitting around.
Since they’re portable, you don’t need to mount them anywhere. Some models will even fit in your pocket — that’s how small they get. In this article, we’ll go over the best portable fish finders. We have reviewed them based on key features, ease of use, convenience, accuracy, and price. Also, if you are a fishing lover, you will definitely need a portable fishing boat.

Venterior VT-FF001
You won’t see the scans in colors on the display. There are no fancy display methods. Instead, you’ll get the information in black and white.
That doesn’t have to be a drawback, though. We find it much easier to read the scans this way, without any weird blotches showing up on the screen.
This device does a lot more than just scan for fish. It gives you readings of how deep the water is and of where rocks, sand, and tall plants are.
You can use the Venterior fish finder at night. Simply turn on the backlight setting for the screen. The fish alarm also helps with nighttime fishing or even ice fishing.
This is a very simple fish finder but it does the job well. With very low depths and a loud alarm, this fish finder really shows you what’s lurking below. With a two-year warranty, this is a great little fish finder for those starting out.
RICANK Portable Fish Finder
The last item on our list is quite modest and affordable. It just goes to show that a good fish finder doesn’t need to cost an arm and a leg!
Sure, the RICANK screen is black-and-white and doesn’t have any fancy display settings. But that’s not a bad thing! For once, it’s a lot easier to read and understand than other fish scanners. It’ll clearly point out to you how deep the school of fish is.
The yellow float connected to the transducer makes it easier for you to spot it in the water. Whether you’re fishing in a lake, river, or by the shore, you won’t lose sight of your precious sonar.
This device has a depth range of up to 300 feet. You can use it in shallower water or deeper waters alike. The sound wave cone emitted is 45 degrees. While you don’t have the flexibility to narrow or widen it, it’s still a decent angle for most kinds of fishing adventures.
Lastly, you can recharge the batteries of both the handheld scanner and the transducer. They both have a battery life of up to 5 hours, but if you turn on the battery-saving setting, it will last you longer.
LUCKY Portable Fish Finder
A LUCKY fish scanner is also an affordable option. It’s smaller than other units, and so more easily transported, but works just as well.
You’ll find that the screen of this fish scanner is much smaller when compared to others on the market. It measures just 2.4 inches diagonally, but it’s still big enough for most people with no visual impairments to see the readings perfectly.
The unit tracks water depth, underwater contour, water temperature, and—of course—where fish are.
A unique feature is the fish attractive lamp. The transducer is yellow and, at the bottom, has two light beams meant to attract fish. It also helps you see the transducer in the dark if you go night fishing.
Both the transducer and the handheld scanner can be recharged. They come with two USB cords for this purpose. The scanner itself has a battery life of approximately four hours, while the transducer lives for up to 10 hours.
ReelSonar Wireless Bluetooth Smart Fish Finder
Another popular choice is the Reel Sonar Wireless scanner. It’s a bit different from the ones we’ve reviewed so far, as it uses your phone to show you where the fish are.
It doesn’t get more portable than this. The transducer (the piece that emits the sonar waves) fits in the palm of your hand. It’s shaped like a small ball and sends the image of what it scans to your smartphone. You can the two via Bluetooth.
On top of all that, the unit allows you to mark fish, map the depth contours and underwater structures, save the water temperature, and memorize your specific location. Then, you can share all this information on social media.
As if that weren’t enough, you can use the unit with its GPS functionalities. Thus, you can mark on the map your favorite spots, a dock, water depth, and so much more.
It’s also worth mentioning that the iBobber has a built-in LED beam and a strike and fish alarm. All this makes it a great option for ice fishing or nighttime fishing.
A great basic tool, this fish finder works with an app for easy use. The app has a whole bunch of features, including alarms that help you see when something is happening under the water.
The beacon makes it easy to spot, but it doesn’t connect well to the app beyond 50 feet, making it less useful for shore fishers. Anglers casting close by should consider this, but, as it has a long battery life and variable fixtures to make it a trusty and versatile tool that can be transported easily.

FAQ for portable fish finders buyers:
How are fish finders powered?
Fishfinders and other electronics need electricity to function. On boats, electricity is supplied from the batteries installed in the battery compartment. The battery is connected to the main switchboard, and the power cable from the fish finder is connected to the same switchboard.
Do fish finders actually work?
If you hang out around a marina, boat launch, or other places where fishermen are with their boats you’ll notice that just about every boat is equipped with a fish finder. It is considered an essential piece of equipment, but for most people, it is a waste of money because it doesn’t help them catch more fish.
Do I need a transducer for my fishfinder?
Transducers are essential parts of every fish finder. Transducers come with different types of mounts. The easiest one to install is the transom mount. But, if you have a bigger boat or need something more serious, you can opt for another type, like the thru-hull mount.
Are portable fish finders any good?
A portable fish finder is a small device that uses sonar technology to detect things beneath the surface. It is great at detecting all kinds of fish, both small and large ones. The best thing about these gadgets is that they don’t need to be mounted on a boat to work.
What do fish look like on a fish finder?
While fish may look the same with a 2D sonar, fish do appear smaller on side imaging because it features a down beam that comes as a narrow slice of the water column. So you’re likely to see something like Crappie looking like circles, or small ovals.
What should I look for when buying a fish finder?
When choosing a new fishfinder, beginning fisherman can be overwhelmed by all of the features and options: Power Wattage, Number of Pixels, with or without Transducer, Display Screen Size, and the list goes on and on. But there is one feature you should not go without and that is GPS.
