How to Choose the Right Fish Finder

There are many factors to consider before buying a fish locator. Following these steps will provide you the information you need to find the best fish finder for you.


  • When you’re looking for a fish locator, the frequency range is important to understand which is the best one for you. There are three types of frequencies, including dual, single, and multiple frequencies. They come in 50, 83, 192, or 200 kHz.
  • Higher frequencies, such as 192 or 200, are ideal for fishing in shallow water. Lower frequencies, such as 50 or 83, are perfect for deep water fishing. To find the right fish finder for you, knowing what area you’re planning on using it in will lead to more catches. Remember that the higher the frequency, the more detail you’ll have on the screen.


  • Wattage is the how the finder is powered. The more wattage you have on the fish finder, the faster the response time will be. If you have more wattage, you can see deeper into the water and find the fish. Fishing in shallow water requires less wattage for better it is to see the surrounding area.
  • When you combine the frequency range and the wattage, you can get a clear picture of what it looks like under the surface. A good way to measure this is to remember that at 50 kHz with every 100 watts of power, you can read up to 400 feet deep. When you’re using 240 kHz at 100 watts of power, you’ll have readings up to 100 feet.

Screen Resolution

  • Just like with TV’s and computer screens, you want a high resolution to see everything. You want a fish locator that has a screen resolution of at least 240 x 160 pixels for sight. If you find that this is too blocky, and cannot tell the differences on the screen, you can opt for a higher resolution screen.
  • When you combine the resolution with the size of the screen, you’ll see more in a clearer picture. You should budget for the best screen you can get for your main fish finder. For a backup, you can settle for a smaller screen, since you won’t use it all the time.

Screen Color

  • While the old black and white screens are becoming obsolete, they can still be practical and useful. Depending on your budget, you may need to settle for a black and white finder. They are good for those who have never had a finder before, or want one as a backup.
  • Colored screens are the new standard, and they are much more reliable than their black and white counterparts. They’re easier to read in the sun and make it easy to see what’s going on around you. If you can manage it, a glowing screen will be more helpful than the black and white screen.


  • The transducer is what makes the finder capable of finding fish. They emit and receive the sonar waves that let you know if there are fish and other objects nearby. When it receives the data, it sends it to the main unit and switches it to the screen. Without a transducer, your finder becomes a fancy screen that doesn’t display any data.
  • While every fish locator does come with a transducer, you may want to invest in an after-market transducer. They can receive data faster, read more of the area, and work better than what comes with the box. You can start fishing right away with one, but you want to make sure you have a transducer that works for you.

Other Considerations

  • You want to consider the transducer material, cone angles, and beams for your finder

Using Your Fish Finder: Best Practices

Once you get your fish finder, you may wonder what you need to do to make sure it works correctly. This step-by-step guide will help you get setup and ready to use the finder.

Check the Manual

To understand how your fish finder works, you want to consult the manual. You can read the terms, and how to program the finder. While you may not enjoy reading the technical babble, it is a good way to familiarize yourself.

Mounting the Fish Finder

You want to put the finder in the best spot on your boat. There are a few different types of mounts you can use. You can choose from a transom, trolling, hull, or portable mount for your boat. Depending on your wants and needs, you can choose the right mount.

Setting up the Fish Finder

You want to turn the fish finder on. It will be set in automatic mode already, with the pre-program settings already on. You can switch it to a manual mode at any time to customized the finder. When you first turn it on, you can leave it in the automatic mode. You then want to drive on the water in automatic mode to get an idea of what it’s seeing.

Adjusting the Settings

The first setting you want to understand is the sensitivity. This adjusts the power of the fish finder, allowing you to see more details. When the power is lower, the quality on display is lowered. You can toy around with the fish finder to find the right setting.

Adjusting the Fish ID Setting

When the fish finder is on the automatic setting, it will identify fish automatically. It’s ideal for those who are trying to figure out their fish finder, but once you adjust to it, you can turn it off. You can see the fish arches, which will give you a better view of what's going on underneath the waves.

Using Auto Depth

If you’ve never used sonar before, you want to keep the auto depth turned on. It automatically tracks the floor of the water, making it easier to see how far down it is. When you become more experienced, you can adjust the setting. The auto depth feature can be adjusted to hide the first few feet underneath, and above the true bottom. It’s useful for setting your sights on the fish you want to catch.

Depth Cursor

The depth cursor is a line that goes across the screen. This line will let you know how far down the fish are, which makes it easy to determine where to put your bait. It will move up and down on the screen, making it easy to find the fish.

Suppressor Setting

The suppressor setting is perfect for blocking out the background noise you’ll experience while you’re waypoints . This setting is normally automatic if the transducer is installed correctly, but you can adjust it for your benefit. You don’t want to keep the suppressor on all the time because it can block out the sonar.

How Does a Fish Finder Work?

Fish finders are an excellent tool that can enhance the fishing experience, and allow you to catch more fish. There are typically only two parts to a fish finder, making it easy for everyone to use. They have a screen or display that fits onto your boat and gives you the information you need to catch more fish. They will display how far down the fish are, and how deep the water is. A fish locator uses a transducer, which takes recordings of the area near the boat using sonar. The sonar bounces off fish, rocks, coral, and other objects under the water.

When the sonar comes back to the transducer, this information is relayed to the display screen. It’s a basic computer showing raw data of what lies underneath the surface of the water. It is easy to read and understand display that will help you find where the fish are swimming. They’re ideal for anyone who wants to get a better idea of the surrounding area under the water. Even if you use it for kayaking, it’s good to know whether you’re near any rocks or logs. You can avoid accidents and map out the water for other adventures if you’d like.

What is a Good Price for a Fish Finder?

There are a lot of factors that go into finding a best fish finder for the right price. Depending on the type of fishing you’re doing will factor into the price tag. There are some that are under $200, while others can run up to over $1000. You should consider where you’re fishing, what type of fish you want to catch, and what features you’ll need.

If you’re on a budget, you don’t want to spend too much money on a fish finder. Some of the finders are ones that do everything you want them to do, and won’t break the bank. If you’re looking for the ideal price for a fish finder, you may want to consider spending at least $300, but no more than $800. Unless you can afford some of the more expensive fish finders, your range should be between $300-600.

Final Verdict

A fish finder is an excellent tool you can use to help you find a fish. They’re great because of what information they can show, and how they work. They are simple machines that can make fishing a more enjoyable outing. If you’re thinking about getting a fish finder, the Deeper Smart Portable 3.0 is the perfect fish finder. It is compact, easy to use, and smartphone compatible.

You can get all the sonar readings right on your phone. If you don’t own a boat, the fish finder is the one you want. It works like many of the other finders, but it attaches right to the line.
