You may be wondering which fish finder is right for you, or if buying a fish finder is even worth the trouble. We’ll cover all of that and more below, including the pros and cons of each AA battery-powered fish finder. Plus, check out our great FAQ section at the end of it all to wrap it all together.
How Do Fish Finders Work?
Fish finders use sonar to “see” what is under and around your vessel. The fish finder does this by using a transducer to send out sound waves into the water.
These sound waves bounce back to the device when they hit something, like a rock, fish, or plant. The fish finder also measures the time it takes for the sound wave to return, which is how it calculates distance and depth.
The level of detail that is interpreted depends on the frequency of the sound waves. The more frequencies a fish finder uses, the more accurate its imaging. One example of accurate imaging is done through CHIRP technology, which is utilized in some of our reviewed fish finders below.
Generally speaking, lower frequencies are better for deep-water fishing and higher frequencies for shallower waters.
Garmin Striker 4 Fish Finder
Garmin has always been a strong name when it comes to fish finders, and the Striker 4 is one of its most compact devices offered to date. Particularly good for use on a small vessel, such as a kayak or jon, this small device packs a powerful punch. It hosts enough features and functionality for any focused fisherman.
Pros ✅
The Garmin Striker 4 incorporates CHIRP sonar technology. This type of sonar uses multiple frequencies with a short wait time in between pulses, making sure the projected image is always up to date.
Its 3.5-inch display may be smaller than competing fish finders, but its clarity and colors make it easy to read; not to mention, it has excellent GPS functions. You can mark your top fishing spots, as well as identify favorite boat ramps, docks, and shoreside campsites.
While you’re fishing, this fish finder tracks your location while also tracking the fish around you. If you’re in an area you frequent, you can even plan for your ride to go over favorited areas where you have caught whoppers before.
The Garmin Striker 4 is waterproof, which isn’t commonplace for all fish finders – although we feel it should be. This portable fish finder’s transducer is also durable and of good quality.
For all of these features, the Garmin is still incredibly affordable and outperforms other fish finders that are much more expensive.
Cons 👎
Some fishermen may not be content with the 3.5-inch sized screen on the Striker 4. With competing fish finders sporting much larger screens, this choice depends on your preference.
Additionally, the Striker 4 does require you to plug it into a 12V power source.
Deeper Pro+ Smart Sonar Fish Finder
The Deeper Pro+ Smart Sonar fish finder is our list’s splurge item, its convenient size fits in the palm of your hand while pairing with your smartphone or Wi-Fi device for your far-out fishing needs.
The Pro+ Smart Sonar fish finder is castable, allowing you to get a better reading of the area you’re fishing in.
Pros ✅
This convenient fish finder maps out the depths of the water around you, creating a map of your path through its GPS.
By saving them on the cloud through your phone’s hotspot, you can even browse these maps later on from the comfort of your own home, tracking where you’ve been and the places you want to return to or avoid on your next trip.
The Pro+ Smart Sonar device uses dual-beam sonar technology to issue fifteen pulses per second – that is one of the clearest and most up-to-date images you can record. You can also choose to implement either a broad or narrow scan, depending on your fishing strategy.
Cons 👎
Even with the use of batteries, the Pro+ Smart Sonar fish finder’s battery life is not the best. Charge it before leaving the hours to ensure you get at least 8 hours of use out on the water.
As with all castable fish finders, you also run the risk of getting it caught or lost in the water if not cast correctly.

The Fishing Buddy is much better at distinguishing between fish and other underwater obstacles, like rocks or plants.

Its 3.5-inch screen may also be a deterrent for some fishermen.
Why Use a Fish Finder?
A fish finder uses sonar input to create an image on its screen. Fishermen can then interpret the image to see what underwater structures are under and around their boat, including any large fish or schools of baitfish they may be looking for.
Fish finders can also provide important information, such as the water’s depth, temperature, and your vessel’s GPS location.
Advanced fish finders can even track your favorite fishing spots, advise you on nearby docking locations, and connect with your smartphone or another Wi-Fi device.
Overall, a fish finder is bound to make your fishing trip more complete, offering exclusive details on your surrounding and allowing you to get closer to reeling in the big guys.
Fish Finder FAQs
Will a fish finder help me catch more fish?
Yes, a fish finder can and will help you catch more fish if used properly. Of course, turning on a fish finder won’t magically bring you to a fisherman’s dream world, but it will provide the details you need to decide when and where to cast your line.
How do fish finders work?
Fish finders use a transducer to send out sonar (sound) waves below and around your boat. These sound waves bounce off of objects like fish, plants, and the seafloor and return to the transducer. The fish finder then interprets this data and projects it onto the screen, displaying the topography of the area around your vessel.

Overall, we recommend the Garmin Striker 4 or Humminbird Fishing Buddy fish finders for the best value. The Striker 4 offers more features at a reasonable price, but the Fishing Buddy comes with the convenience of AA battery life, which means you won’t have to go back to shore or cut your trip short if your device needs more juice.
