What to consider when you’re buying the best fish finder in 2021.

Many fish finders are currently available, and various new & innovative models are coming into the markets daily. These models are different from each other based on their features, functionality, durability, and prices.

Most of the latest fish finders provide extra features that are not always relevant for you in different fishing environments. It’s relatively easy for a lot of fishing beginners to feel lost. Because of these reasons, It becomes difficult for anglers to choose the best fish finder in 2021 for their fishing needs.

But there’s nothing to worry about, Fellow Anglers!

We have put together a complete buying guide that provides all the details you need before buying a fish finder. The most reliable way to find the best fish finder within your budget is the ability to distinguish between the features you must need and the optional features you won’t ever use.

At the end of this guide, you’ll be confident enough to decide, ”What is the best fish finder for you?”, even if you’re a first-time buyer. So, without any fuss or delay, let’s see some of the components below that you’ll see in most of the latest fish finders while surfing the markets.

Different things to know about before Buying a Fish Finder

By understanding the different features of a fish finder, you can easily classify all the components into two categories; the features that your fish finder must provide and the unnecessary features that are optional.

1- Transducers for the fish finders

The way a transducer works is, it cast sound waves in the water in various directions. The waves hit with different objects submerged underwater, including target fish, baitfish, and various underwater structures. The hitting sound waves bounce off, and the transducer receives the waves back for further reading.

The interpretation of received Sonar Waves

The central unit of the transducer interprets the received data in a readable form. The display of your fish finder finally shows the translated data in images. The imagery the transducer provides is very beneficial to give fishing insights to the anglers. The detailed images further help to understand different water structures and tell the potential worth of fishing spots.

The transducer you select will vary according to the waters you choose for fishing. You should choose one that provides clear images at any of your favorite fishing spots.

2-Mounting locations of a Transducer

You can mount a transducer in various locations on your boat. The location where you install the transducer specifically depends on the boat’s most convenient place so that it can fit there easily to do the job efficiently.

The most common spot where a transducer is usually mounted is a boat’s transom. You should go for a Transom mount transducer if you’re planning to fish from a small boat and usually do fishing at low speeds.

In-hull transducers are glued directly to the inside of the hull. You should opt for an In-hull mount if your boat’s hull is either made of fiberglass entirely or thick aluminum that partially covers the hull.

You can mount a Thru-hull transducer through a hole drilled in the boat’s base and extend it directly into the water. The Thru-hull transducer is typical among anglers because it provides the best performance and detailed accuracy.

3-Understanding the Cone Angles

Transducer cones usually vary from 10-60 degrees, but most of the depth finders for boats are coming between 15-20 degrees of cone angles. The transducers with wider cone angles are less effective in shallow waters.

If you are new to fish finders and often go on fishing tours with friends and family, a transducer with at least a 20-degree cone angle will be your best choice to hunt fish in different water depths easily.

4-Understanding the Scanning Sonars

There are generally two methods that a depth finder for a boat uses to scan water structures and lookup for the target fish; Down Imaging and Side Imaging.

How Side Imaging works?

The Side Imaging Sonars let you see all the details on both sides of your boat. Furthermore, the main advantage of such a fish finder with a Side Imaging Sonar is that you can cover a broader range of fishing water horizontally.

Side Imaging is very useful, and anglers mostly use it in freshwater, where you won’t have to explore more in-depth as the water clarity is high compared to saltwater, and fish like to swim near the surface.

How Down Imaging works?

On the other hand, a Down Imaging Sonar allows anglers to scan underwater details vertically. Down Imaging Sonar’s primary goal is to get you detailed and accurate images of a water body where most of the target fish tend to swim near the bottom or more in-depth.

Anglers mostly prefer to use Down Imaging Sonars in saltwater because of salinity in the water and target fish not swimming near the surface. To better understand what’s sneaking beneath your boat, you’ll need the help of a Down Imaging Sonar that supports more power wattage. The logic is that you will have to explore deeper in saltwater, so you will have to send waves more depth than freshwater.


Side Imaging Sonar is very useful when fishing in the water where the water clarity is high because of less salinity, and you can easily spot water in a typical depth. Down Imaging Sonar is very useful when targeting fish in saltwater, where fish naturally like to swim near the bottom of the water bed.

Furthermore, If you are on the higher side of the budget and can’t decide which scanning Sonar your fishfinder must have, you should opt for one that offers both Sonars in 1 unit at an affordable price.

5-Importance of Display

A fish finder’s display is as important in your fishing trip as other components that provide crystal-clear underwater images.

In addition to the display size, the ability to read the screen in various fishing environments, the color range used to display images, and the durability are the key factors to determining a fish finder that can assist you in your next fishing trip.

It would be best to opt for such a fish finder that gives you as much ease as possible while operating it from the display. For example, a fish finder’s touchscreen will help you quickly access the fish finder’s essential functions with a few taps. A large HD display screen will allow you to view more underwater details simultaneously.

6-Importance of built-in GPS in a fish finder

A fish finder with GPS compatibility provides important fishing insights to anglers throughout a fishing tour. When you own a fish finder that provides you with detailed underwater details and the latest precise maps, you get an extra edge on your fellow angler, for sure.

A fish finder with a built-in GPS takes you to your favorite fishing spots easily. Most fish finders with GPS compatibility also allow you to note water temperature and other essential fishing insights. You can get your current location on the water within seconds, whenever you want.

Most of the GPS fish finders combine with Mapping and Chartplotting. Whether you want to continually stay aware of your current location or where are the most productive fishing spots, you can easily do it with maps and Chartplotters.
Furthermore, you can easily store your newly discovered sites as maps and waypoints on an SD card.

6 Questions you need to ask yourself before buying a fish finder

Before buying anything from the internet, many questions come to our mind before we initiate the call of action and purchase the product, we were interested in getting. If the buyer can get satisfactory answers to those questions, it becomes easy for them to choose the best product for themselves.

Keeping the above things in mind, here are the six questions that any angler should ask himself before buying a fish finder, whether they’re a first-time buyer or upgrading to a fish finder recently released.

1-What is the preferred type of water you’ll be fishing to catch fish?

There are different types of water where anglers fish in their spare time. Fishing in these water bodies differs from each other based on some factors, such as salinity level, depth, etc. As the fishing environment changes, the fish locators vary from one model to another.

Three types of fishing in different water bodies are as follows.

1-Saltwater fishing

Fishing in saltwater requires mostly in-depth scanning because fish like to swim near water beds in such waters. You should opt for such a fish finder that does excellent scanning in the water vertically. In easy words, you should go for a fish finder that’s well known for Down Imaging or Down-scanning.

2-Freshwater fishing

Fishing in freshwater doesn’t require in-depth scanning because there’s less salinity in the water and water clarity is high. And secondly, fish like to swim near the water’s surface.

Based on the above factors, you should specifically opt for a fish finder that does excellent scanning in the water horizontally. In easy words, you should go for the best portable fish finder known for Side Imaging or Side-scanning.

3-Ice Fishing

Ice fishing is fishing on a frozen body of water where the anglers use an opening in the ice and use the fishing gear to catch fish. Fishing on icy water is slightly more challenging than fishing in saltwater and freshwater because you can never know what’s sneaking beneath the thin layer of frozen icy water without the help of an ice fish finder. That’s where an ice fishing fish finder comes in handy and does all the hard work for you.

2-What type of boat will you use for your fishing trips?

Whether you’re fishing from a Kayak, Bass Boat, Center Console, or Pontoon, the type of fishing boat matters as well that you’ll be taking for the fishing trips. The primary reason behind this logic is that the proper installation of a fish finder on any boat depends on many factors. Spare space available on the ship, the safety and durability of the fish finder, and how easy it is for you to operate it efficiently are the key factors to consider before installing a fish finder on any boat.


If you mostly take your kayak on fishing trips, you’ll need a portable depth finder because of the small space available on a kayak. Although you can also choose a mountable fish finder for kayaks, it would be slightly challenging to use it in such a situation.

3-What can be the preferred type of fish finder for your boat?

Different fish finders available in the market can be broken down into three major categories, because of the difference in their installation, how they work, and how you can operate them efficiently from a boat.

Portable fish finders

Most companies have designed the best portable fish finder for small boats, where the spare space on the boat is a significant issue. Some anglers also prefer to use handheld fish finders, even if they’re not fishing from a small boat, because of comfortability and ease of use.

Mountable fish finders

Anglers can also mount their fishing units on various spots on a boat so that they can safely drive the boat to their favorite fishing spots and continually see the fish finder’s display at once. Mountable fish finders also need you to spend some time for a proper installation as the process is not necessarily the same for all boats.

Castable Fish Finders

Fishing with the help of the best castable fish finder is very useful when you’re fishing from shore or near the coast. You can attach the floating transducer with the fishing reel and cast it into the water. Because of their unique working, such units usually connect the transducer with the smartphone through Wifi or Bluetooth connectivity. You can get all the underwater images on the synced smartphone in no time.

4-What is your budget, and how many bucks can you invest in a fish finder?

One of the most important questions you should ask yourself before buying anything off the internet is your budget and the maximum amount you can invest in that specific product. Such an action will help you get a fish finder that’s most suited for your fishing needs and meets your budget.


If you own a small boat, such as a kayak, and you’re low on budget, you should go for one of the best portable fish finders. It is the most economical choice you can make while choosing from a list of best fish finder GPS combo & kayak depth finders on a limited budget.

If you own a medium-sized boat for recreational or commercial fishing, you should opt for a fixed fish finder that falls under a medium budget. The long-run advantage of a mountable fish finder is that you can use it on a kayak (you’ll have to be slightly careful while using it on a kayak) and easily adjust it on a boat as well.

5- What features and functionalities should your desired fish finder have?

Most fishing units come fully packed with various features you may not need in different fishing environments. If you often fish in freshwaters, select a fish finder equipped with a Side Imaging Sonar rather than Down Imaging.

Furthermore, suppose you’re mostly fishing in local small lakes, and you’re entirely familiar with the areas of those small lakes. In that case, you don’t need a fish finder integrated with preloaded maps. As a result, You can save a noticeable chunk of money this way.

6-Are you going to use it as a recreational fisher or a commercial fisher?

The crucial question determining your budget is whether you’ll use that specific product for personal or professional usage.

Recreational Fishing

If you’re someone who especially goes on fishing trips in your spare time as a recreational activity, you should go for a budget-friendly fish finder that can accurately do most of the tasks to help you catch more in less time.

Commercial Fishing

If you’re commercially attached to fishing and catching more fish is your goal, you’re a commercial angler. You should prioritize a pricier fish finder with all the necessary features and functionalities to achieve your desired productivity.

The extra amount you invest in a more expensive fishfinder will reflect a wrong decision at first. Despite the extra money you invest, the additional perks get you more fishing productivity at that price.
