The Best Fish Finders Are:

As we mentioned, our top pick for beginner fishers and professional fishermen alike is the Garmin Striker 4 with a transducer.

One of the best things about this fish finder is it can easily toggle between the modern-day fish viewer view and the classic flasher format. This makes it perfect not only for regular fishing but also one of the best ice fishing fish finders and vertical jigging options as well. It’s also incredibly easy to use and an overall high-quality product.

What We Would Love to See Improved

While the Garmin Striker 4 is portable, it does require a 12v battery to be used, so be sure to stock up on an extra battery or two. This will make transportation a little more complicated, but it’s worth it once you know when to switch batteries.

  • Backed by the reputable Garmin brand
  • One of the most accurate fish finders on the market
  • Intuitive and easy to use interface

We’ve also reviewed more recent models such as the Helix 7, Helix 9, and Helix 10.

What Needs to Be Improved

What We Would Love to See Improved  

While this is a fantastic all-around fish finder, the expected battery life is roughly one year, which is unfortunate. While ordering a replacement battery is easy, it can be an inconvenience and comes at a cost.


  • Great value all around
  • Highly accurate and user-friendly
  • One of the best ones designed for ice and shore fishing



  • You need to replace the battery every year
  • Safety strap could be improved

What We Like

The 5-inch color display is one of our favorite interfaces its category. The accuracy and resolution of the Garmin Echo is the top of its class. We loved the Quickdraw contours for creating custom HD maps.

What We Would Love to See Improved

We would love for the Garmin Echo to work in both saltwater and freshwater out of the box. Unfortunately, you need to purchase each fish finder individually depending on where you’ll be using it.


  • Great value when considering the features
  • Screen is bright and simple to navigate
  • Easily detaches from mount for quick storage



  • A little pricier than similar options
  • Some of the added functions and features can be overwhelming for new users

We also talk in more detail about 2 other Garmin fishfinders — the Garmin EchoMap 73sv and the Garmin Striker 4.

HookK2 4X

The HookK2 4X is an excellent general fish finder for those looking for quality that costs less than $500. The HookK2 4X stands out with its ease of use while not sacrificing the features you need for the job.

This fish finder includes auto-tuning sonar to help ensure all data is accurate and up to date, so you never miss your target fish. The HookK2 4x also comes with wide sonar coverage, giving you up to two times the coverage of other fish finders on the market.

Key Features

What We Like  

The Lowrance fish finder is a great value due to its affordable price and ease of use. Out of all the fish finders on the market today, it is one of the easiest to get set up and running. The HookK2 4x also includes built-in depth mapping so you can find your next favorite fishing spot with over 3000 lakes included in its mapping software.

What We Would Love to See Improved  

It does not include a GPS out of the box, which is a must-have for fish finders today.


  • Great all-around value and can fit any budget
  • A fantastic investment for kayak and boat use
  • Includes wide angle CHIRP sonar for added accuracy



  • Does not include a working GPS out of the box
  • While affordable, the durability is lacking compared to similar options


The display is easy to view even in the toughest sunlight conditions. You can save your map markups and take your data elsewhere with its included micro SD slot. That said, the fact that it does not include a working GPS out of the box is a pretty big letdown. If you don’t need help with navigation or have a separate GPS unit, this may be the best for you. We review other Lowrance models here.

Buying Guide for Beginners

A fish finder is essentially a tool that uses sonar technology to help you locate schools of fish so that you can put yourself in the best position to make the catch. Fish finders are also incredibly useful for getting the lay of the land (or in this case water), so you know if there are objects in the depths below.

There are two main types of fish finders — portable and fixed. However, we believe that for most fishing use cases, portable fish finders are the way to go. Castable fish finders are a type of portable fish finder that bob in the water. If you plan on staying on a dock and not in a boat or kayak, this can be a great option to consider.

If you spend much of your time on and off the water, it may be worth purchasing both a fixed and portable one depending on your needs.

The Screen

When investing in a fish finder, you want to make sure that it has a high-quality screen that is both easy to read and navigate as well.

When out fishing, you’ll likely be exposed to the sun, which can make seeing your screen difficult. Therefore, it’s imperative to choose a fish finder navigation system that comes with glare protection.

You don’t want to have to use your hand to cover the screen just to see where the fish are.

Additionally, you want your fish finder to include a light setting that allows you to see the screen if you’re fishing in the early mornings or late evenings where there is very little natural light.

While added glare protection and low light settings may seem minor, they can make a huge difference in your overall fish finding experience.  

Screen size is also incredibly important when choosing your fish finder. Bigger screens make it easier to see where exactly the fish are as well as adjust various settings. Most portable ones can easily fit inside your tackle box.

Fish finder screen sizes range from 3 inches to 16 inches; however, we recommend going for a screen that is on the smaller side if possible. For most use cases, a smaller to medium sized screen is more than enough to see all the critical data you need.

Do You Need A GPS?

We recommend that you choose a fish finder with GPS functionality for added convenience. That said, if you mainly intend on staying on a dock or a single location, GPS might not be a priority.

If you’re going to be investing in a high-quality fish finder, it often makes sense to choose one with a GPS just in case you go out on multiple fishing excursions and your needs change.

Fish finders without a GPS are generally less expensive, but the small additional cost is often worth the investment if you plan on fishing in multiple locations over the year.

Down Scan or Side Scan?

When it comes to fish finders, there are generally two types of modes.

The first type of fish finder is the down scan fish finder. This fish finder scans the water directly below your boat.

The second type of fish finder is one that scans sideways from your boat. Some fish finders offer both options which you can toggle depending on your needs.

Having a comprehensive view of below your boat and to the left or right of your fishing location can help you find the best place to fish.


High wattage fish finders will have more range and scope than fish finders of lesser power. So, if you plan on fishing in deeper bodies of water, you generally want to purchase a finder with more power.

Generally speaking, 100 watts of power at 50 kHz will allow for your fish finder to accurately detect fish in the range of 400 feet. A 100 watts of power at 200 kHz, the level provides around a range of 100 feet.

Water Resistance

Another thing to look at when choosing your fish finder is its level of water resistance.  Not all models are designed to be submerged several feet underwater, so it’s important you choose the right one for your needs.

Some fish finders can be in water up to 10 feet deep while others are explicitly designed to sit on top of the water.

Final Thoughts

Whether fishing is just a hobby, or you’re an experienced fisher who wants to improve their skills, investing in a fish finder is a must. We hope our top fish finders guide helped you make a decision.

Our top pick is the Garmin Striker 4. It will provide all the features you want without breaking the bank. Where others might lack GPS or have a dim screen, the Garmin outshines them all.

That said, look over each device to see if it better suits your unique fishing style. If you are on a tight budget, you might want a decent but cheap fish finder. If you fish in saltwater and freshwater, make sure your device can handle both areas.
