11 Best Fish Finders: Review And Buyers Guide

Using the best fish finders helps me put more fish in the boat like this 58" musky.
Me and my clients with a 58″ musky. My fish finder allows me to cast and troll precisely, which results in many more fish for my clients and me.

I guided out of a boat for 17 years for musky, bass, walleye, steelhead, and salmon, and I was often in treacherous waters full of rocks. I’ve always used the best fish finders within my budget because I knew for a fact that I would not catch half as many fish without my fish finder and GPS.

I also knew that my fish finder with the GPS kept me and my passengers safer on the water, and it even prevented expensive damages to my boat and motor. With the GPS and mapping system and boating knowledge, I didn’t hit the same hidden rocks other boaters did. Instead, I fished around those rocks and caught plenty of fish.

I even told new anglers that a fish finder with a GPS was more important to me as a guide and angler than the 200HP Merc motor on the back of my boat.

About Fish Finders

The fish finder has come a long way since Japan’s Furuno brothers first designed a device to detect fish in 1948 and Darrell Lowrance turned the idea into a commercially viable fish finder in 1957.

Lowrance Electronics was the first commercially successful maker of the fish finder, but there are many companies making many types of fish finders today.

Types of Fish Finders

In their most basic forms, fish finders fall into one of three categories. Those are standalone, combination, and network fish finders. A standalone fish finder only scans for fish and does nothing else. They are effective, affordable, and usually have the largest imaging screens.

A combination fish finder locates fish and offers chart plotting capability via GPS technology. A network fish finder uses a variety of data sources, including GPS, Wi-Fi, and satellite radio, to provide a wide

You can also use one of 13 types of fish finders that use one of six different types of sonar. Some might offer two or more types of sonar, such as 2D, down-imaging sonar, or side-scanning sonar. Those three types are what most fish finders use to locate fish and structure.

Other types of sonar used are live, 360-imaging, and CHIRP. Each type has distinct advantages and disadvantages, but they all help to increase the odds of catching fish.

How to Choose the Best Fish Finder

Determining the best fish finder for your needs starts with determining your budget and the type of fishing that you would do with it.

If you are a charter boat captain, you could spend thousands of dollars on the best fish finder that helps you increase the odds for your passengers to catch fish. Those who mostly fish local lakes in smaller boats likely would find an entry-level fish finder with an accessible price point would work well.

You’ll want to look at features like CHIRP, down-imaging, and side-imaging sonar systems for finding schools of fish. You also should consider some of the following factors to better know which fish finder would be the best overall.

Factors to Consider When Buying a Fish Finder

Examining six common factors can help you to identify the most compatible fish finders for your purposes. You should look for the following marine electronics features to find the best.

  1. Power — Fish finders usually need an external power source from a 12-volt marine-grade battery. Some portable models might have internal rechargeable batteries or accept disposable batteries to power them.
  2. Frequency — Low-frequency sonar systems of about 50 kHz give you a wide range of the waters below while higher-frequency sonar systems of about 200 kHz to 800 kHz are better for targeting schools of fish and acting as a depth finder.
  3. Screen Resolution — Better resolution makes it easier to read the screen and easy to navigate shallow water while using a trolling motor with your fish finder.
  4. Transducer — The transducer is what sends the sonar signal that makes a find finder work. It might be fixed to the boat’s hull or placed in the water when using a portable fish finder.
  5. GPS — GPS tracking enables more advanced fish-finding equipment to follow charted courses and show premade maps of the lake bottoms and coastal areas.
  6. Networking — Networking combines multiple sources, like Wi-Fi, satellite signals, and GPS, to create virtual maps of the waters you are fishing so you can make sure you are where you need to be while fishing.

What is a Fish Finder?

Fish finders use sonar waves to locate fish and underwater structures that hold them. It’s the same technology that the U.S. Navy used to help win World War II and can help you win the battle with big fish.

Active imaging will show you where they are and in which direction they are moving so you have a better chance of catching fish.

How Does a Fish Finder Work?

The majority of fish finders have two basic components that make them work and help you catch more fish. One is a transducer that you submerge to send sonar waves that locate fish. The other is an LCD screen that shows you what the fish-finding transducer has located, how deep they are, and how many are within the sonar range.

Why Do You Need a Fish Finder?

Anyone who wants to catch fish needs one of the best fish finders to find the fish and spend more time catching them than searching for them. A fish finder finds the fish and tells you how deep and about how many are down there. Some fish finders even tell you which species it has located so you can target specific ones.
