The adventures and thrills of catching a big fish are things that a lot of anglers strive for.

Some of them started fishing because of passion, while others are doing it because they consider it as a kind of sport.

Then, of course, there are those who make a living through fishing.

To fully enjoy fishing, you need the right equipment, and you need to buy them from a trusted brand.

Fishfinders are one of the most important devices that you need to have when fishing. They provide the data that you need in order to locate where the fish are.

Among the different brands in the market, Lowrance is one of the best and the most trusted.

It has been in the market for over 60 years and has pretty much an established prestige when it comes to marine electronics.

These Lowrance fish finder reviews aim to help you find the fish finder that matches your fishing preferences and needs.

History of Lowrance Electronics

Lowrance Electronics is the leader when it comes to marine electronics.

It has been in the market since 1957, so it has already built a strong reputation over the years, especially its portable sonar.

In the 1950s, most people rely only on their knowledge and experience in order to find fish.

There were a lot of advancements in rod and reel technology, but finding fish was more like a guessing game for most anglers.

These all change when fishfinders were invented.

The Little Green Box

Carl Lowrance and his sons, Darrell and Arlen, decided to change the course of fishing when they invented the first consumer sonar device—The Little Green Box.

Carl was an avid fisherman, and both his sons inherited the same enthusiasm. The idea for the Little Green Box started because of their hobby.

Carl and Darrell were among the few skin divers in the country, so the experience that they had underwater taught them a lot of things about fish.

Building the First Consumer Sonar

Since Carl was a flight instructor, he already knows sound, navigation, and ranging (SONAR) technology.

This tech was developed by the U.S. Navy during World War II to track the submarine movement of the enemy.

After the war, a lot of fishermen decided to use sonar for fishing, but the machines that they were using were too bulky and, therefore, not a good choice for small crafts or individual anglers.

The main idea of Lowrance was to use sonar for sports fishing, which means that it has to be small enough to be used by small boats.

With the transistor technology, Lowrance was able to reduce the size of the sonar so that it can be mounted to a small boat and operated by batteries.

Darrell Lowrance was studying mathematics and physics at the University of Arkansas, and he was able to reduce the pulse length of the device to one foot, just small enough to identify large fish.

In 1956, the whole family released the first unit, and it was known as Fish Lo-K-Tor. In 1958, their business became known as Lowrance Electronics, Inc.

Lowrance Fish Finder FAQs

1. Do I need a transducer for my fish finder?

Yes, a transducer is the sonar part of the fish finder, and it is the part that sends signals to the water.

It will then sense the echo from underwater to tell you where the fish are and to help you navigate.

The primary goal of buying a fish finder is to find fish, but if the fish finder doesn’t have a transducer, it will not do its job properly.

There are still some fish finders that don’t have transducers, but you have to buy a separate transducer to use it.

2. What should I look for when buying a fish finder?

When looking for a fish finder, you need to look for CHIRP technology, as it provides a clearer view of what’s under your boat.

GPS functions should also be present.

The fish finder should not be too expensive unless you have a lot of money to afford the high-end models.

A high-contrast and high-resolution display should be considered, as well.

Finally, you need to check the size of the fish finder. If it's too big, it won’t be portable, but if it is too small, it would be hard to see the functionalities on the screen.

3. Is side imaging better than down imaging?

Both of them are important for fishing because down imaging detects fish deeper into the water.

On the other hand, the side imaging feature detects the environment underwater.

If you are going fishing, your fish finder should have both of these features so that you can have a better view of the fish and objects under the water.

4. Do I really need a fish finder?

Professional anglers don’t rely too much on fish finders because they always think that the sport is more thrilling if you will only use your knowledge and experience to find your target.

For hobbyists, using a fish finder help save more time because you can just focus on fishing, and the fish finder will find the fish for you.

Using a fish finder is just a matter of personal preference, but if you want your fishing to be smooth and more accurate, getting this device
