Fish finders have become essential gear to have whether you’re standing on the edge of the lake, or you go deep sea fishing. They help shorten the time it takes to your catch, and provide better insight for newer fishermen.

More Detailed Portable Fish Finders Reviews
Deeper PRO PLUS Smart Fish Finder Review
Deeper PRO is the best fish finder because it floats right on the water, and scans nice and deep. 79 meters of underwater coverage gives you every bit of information you need.
Shore anglers will love the built-in GPS navigation system, aiding you in the right spot to cast your line. Deeper PRO really took the cake because of its ultimate scan function.
With 15 scans per second, you end up with constant up-to-date information at all times, giving you an edge over every fish in your path.
Humminbird HELIX CHIRP GPS Review
Humminbird continues to be the best fish finder for the UK market, strictly because of its GPS function that really contours to our map (not just designed for US use, for once).
With a 12.7 cm color display, all information is displayed accurately and is easy to read. Small details on the map become extremely vibrant.
You can add a micro SD card for expanded storage, or use the on-board memory to store images of maps and previous routes for later use.
CHIRP dual beam and PLUS sonar work together to give consistently accurate information, with a small 615mA power draw for better battery life.
Garmin Striker Plus GPS Fish Finder Review
Garmin has always and will always be a top-tier brand for the outdoors, and their Striker Plus just solidifies that fact. As one of the best portable fish finder units on the market today, it comes with a little bit of everything.
Built-in mapping gives you the best storage for maps, so you can get back to your original fishing spot quicker the next time around.
Everything comes encased in an IPX7 waterproof rating, which is more than enough for ocean splashes and some rain.
At the end of the day, it’s Garmin’s 2M+ acre mapping, enhanced sonar, and crystal clear on-screen visuals that really take the cake.
Raymarine Dragonfly 7 Pro Sonar and GPS Review
Raymarine packed a punch with this sonar and GPS combo, displayed on a 17.7 cm display with vibrant color and perfect clarity so you know exactly what you’re doing at all times.
Designed for power above everything else, Raymarine definitely charges a premium, but includes the built-in down vision, and CPT-DVS without needing an SD card to run it.
Overall, it’s a lightweight system that doesn’t require a huge power draw. You can hook this up to solar panels to operate it if you wish.
Lucky Wireless Fish Finder Review
Often hailed as the best fish finder for a small boat, this lightweight unit doesn’t require a lot of power to turn on and run well.
With nearly 9 cm of visible screen space, you get vibrant color to see everything on, although a low resolution.
With audible alerts, you’ll always know when fish are close and when it’s the right time to cast that reel. From 1 to 100 meters, you’ll know where everything is.
Built to be the best fish finder for kayak use as well as ice fishing use.
Portable Fish Finders FAQ
What Should I Look for When Buying a Fish Finder?
Fish don’t remain static. They’re constantly on the move, meaning you have to get up-to-date information as often as possible. For this, you want multiple scans in any given minute, as well as GPS navigation.
Display is also important, because information is useless if you can’t effectively read it. LCD screen size and brightness settings matter, specifically because of screen glare during bright daylight hours when we’re all commonly fishing on our boats.
Usability, battery life, and a comfortable UI is also important. At the end of the day, you want extensive, up-to-date information on a visible screen.
How Does a Fish Finder Work?
Fish finders use sonar, which is actually an abbreviation for sound navigation ranging. This is like a miniature version of what you can expect to see in submarine sonars, with little to no impact on marine life.
A sound pulse is sent out, and it returns back to the fish finder with information. Upon returning, another pulse is sent out to bring more up-to-date information in front of you.
Are Portable Fish Finders Any Good?
Yes, they can be useful, but they don’t have the best battery life. Almost all portable fish finders are powered using lithium-ion batteries, and while these can be hooked up to and charged by personal 5W solar panels (which you can mount on your boat), it might not be enough to sustain an all-day fishing affair.
Do You Really Need a Fish Finder?
You don’t need one, but they’re helpful. The fun of fishing isn’t sitting by and waiting for your reel to catch something; it’s about casting, catching, and pulling it back to shore (or the side of your boat).
Fish finders help drastically cut down the time you have to spend actually finding a good fishing spot. Not to sound bleak, but with the way marine life is shrinking due to overfishing and pollution, it’s not going to get any easier to find fish in the near future.
Do Cheap Fish Finders Work?
They work, but not well. You can expect a cheap fish finder to perform basic scanning up to about five or ten meters in the water, but depending on where you’re fishing, it won’t be enough. You don’t need a fish finder for lake fishing, but if you were going to use one, a cheap one would do the trick.
