Fishing is one of those activities that can be traced back to the olden days where people simply relied on a few tools and their instincts to catch fish. Nature cannot be relied upon to maintain the same conditions and that is why we will be reviewing the best fish finders for 2020 with side imaging for maximum catch, because fishing these days without technology can very be challenging.
Sometimes you go out looking for fish and come back empty-handed. However, advancements in technology have enabled people to have easy time fishing and actually catch fish. These advancements in technology include fish finders with side imaging, GPS enabled, ice fishing and many more.
A fish finder is very important because it enables you to know where the fish are. Definitely you will not be able to catch fish if you are fishing where there is no fish.
Fish finders enable you to save time by removing the frustrations that you would otherwise have and making your fishing experience wonderful. A basic fish finder is made of two parts which include the transducer and the display.
Other fish finder models have whistles and bells. The display shows the readings while the transducer is normally attached to the ransom or hull and does most of the work. Some portable models have a transducer that you just place into the water on a cable.

A transducer is any device used to convert energy from one form to another – typically when converting input energy into output energy. For transduction to occur, a change from one form of energy must also take place, such as a conversion from mechanical to electrical energy or vice versa.

Difference between a fish finder and a depth finder.
Fish finders are sonar (Sound, Navigation, and Ranging) units that release high-frequency sound waves into the water which thereafter bounce off any solid objects on the way. These returning waves are gathered by the sonar unit which processes them through a tiny computer circuit. By the fish finder moving across the surface over time, it develops an on-going two-dimensional picture of what lies under the surface.
A depth finder is usually compared to a fish finder because they both use sonar which helps in finding the bottom surface of the water as well as fish. However, those people looking to buy a depth finder are more interested in finding the depth of the water than fish.
These people may not even be fishermen but rather they may be interested in positioning their boats on shallow water. A digital depth finder or a depth finder as the name suggests provides you with a display of depth information. The information shows the depth of the water under the boat which is mostly used to detect shallow water depth when there is no need for a graphic display.
Divers may also need a depth finder to enable them to know about the best water diving spots. Fish finders can also be useful in this case; however, they may not be able to reach certain depths because they are mainly interested in finding fish.
They also will not be able to determine the water depth in certain areas because the areas are very deep. A depth finder can help you catch more fish. They are quite expensive but easy to read and dependable. Depth finders use sonar to measure the depth of a water body and immediately display the information.
What to Consider before purchasing a fish finder
If you are looking for a fish finder and you do not know what to look out for, this buyer’s guide is for you. Here are the major factors you need to consider before purchasing fish finders or depth finders:
There are fish finders without a proper GPS system which we do not recommend. A GPS system enables you to mark return waypoints, download pre-made maps of various water bodies and their topography and others provide you with customized navigation and cartography. Fish finders equipped with GPS give you information about your location and the objects besides and under your boat.
This information is very important especially when it comes to navigating the water, scouting for new waters and finding productive fishing locations. Currently, most fish finders come equipped with GPS. This factor also applies to depth finders because you will be able to find the location of shallow water.
High-Quality Display Screen
No matter the amount of data collected by a fish finder and depth finder, it will not be worth much to you if the information cannot be easily displayed on the screen. You need to choose a fish finder which has the best display screen.
In addition to choosing a display screen with high resolution and full-color images, you need to select a fish finder with the biggest screen. Choosing a bigger screen will enable you to easily view images when you are close to the unit or when you are at the other end of the water body.
Most of the finest fish finders enable you to customize the way the transducer gathers information which is very important when it comes to optimizing the unit and how the information is displayed.
A good example is how some fish finders enable you to change the colors on display. These colors are very beneficial in terms of maximizing the visibility and contrast displayed in dim lighting or bad weather. Most fish finders will enable you to choose different data types to display.
Wireless Device Compatibility
Most modern fish finders are able to connect to other devices like your tablet or smartphone. This feature enables you to control your fish finder and see the images they produce wherever you are on your boat.
You can transfer data which includes custom maps, navigation routes and way-points to any of your other digital devices. Many modern fish finders are compatible with both iOS and Android-based devices; however, it is still important to check whether the one you want to purchase is compatible with your devices.
Fish finders vary in the way they are designed to be installed in your boat and the degree of difficulty they present during the installation process. It is recommended that you choose a unit that you can easily install. This is especially important for those who have to repeatedly mount and remove them. For example, those who rent boats for fishing would want to a fish finder that is easy to install so that they can install it and remove it easily.
Type of Use
One of the main factors that you need to consider before buying a fish finder is what you are going to use it for. You need to determine whether you are fishing offshore or from a lake’s kayak in several meters of water.
You need to determine whether you are looking for a place to ground your boat or whether you want to determine the depth of water for fishing purposes. For example, if you are fishing from a kayak, you do not need a large fish finder because you have to consider the issue of space. In this case, you are better off using a more vertical small fish finder.
Suitability of the Transducer
You should consider the transducer before making a purchase. The transducer is the most important part of a fish finder because it sends the sonar waves to the water and displays what lies below the water surface. It was designed on the mechanism of sending a fishing probe which bounces off the fish or any object and is displayed as an image on the fish finder screen.
If the transducer is weak, you will not be able to locate fish or determine the depth of the water at all. Currently, a wide range of sonar types are available which include sidescan, downscan, different types of sonar frequencies and structure scan. These technologies combined are ideal for different types of fishing and different locations.
You need to pick the right transducer material depending on the type of boat you will be using. A plastic transom mount is ideal for casual and enthusiast fishermen. This material is compatible with almost all kinds of boats. Those who are using a transducer with an in-hull mount or a thru-hull mount, metal hulls or fiberglass require plastic housings.
Steel or aluminum hulls require stainless steel housings. Boats with wood or fiberglass hulls require bronze housings. For recreational users, most fish finders come with trolling motor transducers or transom mounts transducers. These are compatible with almost any type of boat and all you need to do is ensure that you follow the installation guidelines.
Black and White Screens vs. Color Screens
Currently, color screens have become the standard in all electronics. They offer displays of up to millions of colors and so much detail whereas black and white screens only offer 265 shades of grey. The information put out by a transducer is easier to read and understand with a color screen. Black and white screens are harder to read in direct sunlight or during dark or cloudy weather.
With the above buyer’s guide, I guarantee that you will be able to buy the right fish finder. Consider the type of use and your preference to get the one that best suits your needs. All the best!
